Denon AVR-1509 (Year 2009 Model) is HERE !

The all new Denon AVR-1509 (Year 2009 model) is here. When it comes to home cinema sound, Denon is one of the best in the home theater brands. Denon has been awarded with many WhatHifi awards (whathifi.com) with its high end receivers and amplifiers. Nevertheless, Denon has never neglected the lower end market and by providing entry-level models such as this AVR-1509 at an affordable price of RM1,799 msrp, most of us can enjoy quality sound from this solid built AV Receiver without worrying a bigger hole in our wallet.

Like the previous model AVR-1508, this is a 7 channels AV Receiver that produces 75watts (8 ohms) x 7 channels power. You get to enjoy DTS surround sound, Digital EX, ProLogic II/IIx, ES Discrete6.1 and ES Matrix 6.1 sound. It supports 2 HDMI 1.3a input and 1 HDMI 1.3a output for your LCD, plasma or project with HDMI input.

The only downside of this AVR-1509 is that it does not come with the video upscaling features as compared to the higher model AVR-1709. There is no audio transfer via HDMI from your Bluray dvd player. The component video bandwith is also rated at 30Mhz only and there is no bi-amp supports for your speakers.

However, at a price tag of RM1,799 msrp, this is a highly recommend equipment for entry-level user. So? Why wait? Get it at Sound Fusion Sdn Bhd located at 3rd Floor Wisma Satok, Kuching, Sarawak. Malaysia. Tel: +6 082-420020

Why Sound Fusion?

Buying a set of new home theater system is a big decision, and with so many options and brand names available, how do you decide which one is right for you?










At Sound Fusion Sdn. Bhd., we can provide the information you need in finding the most suitable home theater set according to your budget.










An expensive home theater does not always out perform a cheaper one. The formula is how to match the speakers with the amplifier or receiver.










I have seen and known too many people who have spent their hard earned cash into consumer brand, didn't realize they are just wasting their money in buying those all-in-one system. I will go into more details on why those systems are totally a waste of cash and investment.










Problem with most consumer brands all-in-one system is over heating problem with the amplifier and the build in dvd player. Most of them are having heat issue where user cannot use it for extended period of more than 3 -4 hours. You will notice image degration and sound distortion after 3 -4 hours. Some dvd will start to skip chapters or experiencing occassional pauses throughout the tracks. Continue to operate will cause serious damage to the system.

That is why audio specialist chooses standalone av receiver/amplifier/dvd for durability. You pay a little more BUT you use it longer (more than 10 years on most cases).

This blogspot brings your awareness on why you should save enough for your next system rather than throwing your money into the drain when the all-in-one system goes into waste after couple of years.

Do the math !

The Misunderstood Aspect of your Screen Shape

Nearly everyone has been into a store and seen the new, huge HDTV sets. At some point, we probably notices that the screen is more rectangular than square, and while this fact may have made a small impression, the reasons why, and the impact of the new shape may have gone right on by us. Here’s some help.

So what do we call it? To call it rectangular is not very specific. Just how rectangular is it? To define its shape in a number to two, it’s been reduced to a ratio of width to height. A standard TV has a width to height ratio of 4:3, which can further be reduced to 1.33:1. Sometimes this is just stated as 1.33, assuming the “:1” part as understood. That aspect ratio came from the early days of movies, when the screen size was picked. It was standardized as 1.33:1 nearly 100 years ago, in 1907, when the fledgling film industry recognized the need to set a standard film size and frame shape. Yet, even as early as 1897 there were experiments with wider screen shapes. But big changes really happened in the early 1950s, when TV began to supply to the consumer the bane of movies existence: free entertainment. To the TV boys it made perfect sense to make the screen the same aspect ratio as movies, since there would probably be a lot of film shown on TV. But size and shape aside, TV did one thing very well…it caused theater ticket sales to plummet. The movie industry was desperate to save itself in any way it could. It stepped up the production of color films, but TV responded by announcing that it too would soon be in color. The movies only real option was to build on the physical size of their screen, to emphasize that a movie was more of a special experience than just entertainment. So, out of desperation, the movie industry developed ‘wide screen’ movies. But since wide screen was more of a knee-jerk reaction than a well-planned strategy, there were many different systems, film formats, and aspect ratios tried. The names of these processes are entertainment in themselves: CinemaScope, Cinerama, Panavision, Super Panavision 70, Technirama, Todd AO, VistaVision, and more. (My favorite one is “Cinemiracle”…just the name, not the wide screen process). Enough to fill a book! And in fact, it did. You can buy “Wide Screen Movies – A History and Filmography of Wide Gauge Filmmaking” by Robert Carr and R. M. Hayes on Amazon.com for the full story. It’s an exhaustive studio of the wide screen movie concept, the variations, screen sizes and shapes, and the people that invented them (or in many cases just copied from others!) While much of the book is an extensive filmography of each wide screen process, the stories of the development of these formats is nothing short of fascinating, though possibly not quite worth the hefty price of the book.

But back to wide screen movies. Since each process was somewhat different, and movies had to show on thousands of theaters, there had to be at least some standards. Two methods proliferated above all others. Generically known as “Scope” (from CinemaScope), but used to refer to any film made with an anamorphic process, the screen became 2.35:1. The film is shot through special lenses that squeeze the image horizontally by 2X, then re-stretch it during projection to take a 1.18:1 film frame (yes, it was more square than even 1.33) out to 2.35. The various squeeze/stretch amounts were eventually standardized, and we now have “Panavision”, a company that makes equipment used to produce the current most popular “Scope” format. But, since 2.35 was quite wide, and some theaters couldn’t even show the full width properly, and since there are limitations in cinematography imposed by the special lenses, the Academy of Motion Picture Arts and Sciences chose to standardize an in-between aspect ratio of 1.85:1 (known today as “flat” in the film world). It requires no special lens, and is achieved by masking off the upper and lower parts of a 1.33 frame by using an appropriate aperture plate in the projector. Cheap, easy, and at no additional cost…the film industry embraced it wholeheartedly. With very few exceptions, all films made today are either 2.35:1 “scope” (anamorphic) or 1.85:1 “flat”, and shot on 35mm film.

Fast-forward to HDTV. The TV industry had long experienced the difficulty of showing a 2.35 scope film on its 1.33 screen. You’ve seen “letterboxed” versions, panned and scanned versions, and just plain bad cropping where one of the key actors is on screen in the theater, but off screen on TV. Since every theatrical film made in the last 40 years was at least 1.85, but TV was standardized at 1.33 over 50 years ago, broadcasters had a problem, and with new standards being developed for HD television, they had a chance to solve it. But the problem proved more thorny than anyone though. Introducing a new standard aspect ratio in TV would alienate old TV viewers. You’d have the cropping and pan/scan issues all over again, but this time on every program all day long, not just movies. It would have made sense to pick an HD aspect ratio that matched Hollywood’s 1.85 standard, right? But broadcasters know about compromise, and being worried about letterboxing a standard image within a 1.85 frame, they chose a compromise of 16:9, which reduces to a rather inconvenient ratio 1.7777777:1 (the 7’s go on forever). Now, you have to wonder what drove this. And the simple answer is, it's related to the problems of scanning the front of a picture tube with an electron beam, and getting it to work into the corners of the tube. Yes, it's rooted in a display technology that virtually vanished once 16:9 flourished. Sure, as HDTV slowly penetrated the market, for a time there would be two side bands when a 1.33 image was shown on a wide screen TV, but soon every TV made would have the new wide screen, and eventually 1.33 sets would go away. But rather than match the prevailing 1.85 standard, they picked the 1.77 compromise because it results in a little letter box to show 1.77 on a 1.33 set, and a little vertical letterbox (pillarbox) to show a 1.33 image on a 1.77 set. Neither is optimized, and when you see a real wide screen ‘scope film, it’s always a large letterbox. Actually, my personal theory is that Broadcasters picked 16:9 because it matches the aspect ratio of the original Star Trek series View Screen. Hey, it's as valid a reason as any other given.

Simply put: they goofed, big time. They compromised the long term aspect ratio by catering to a short term problem. It turns out nobody likes to see a letterboxed image, and constant display of a letterboxed image will actually burn a letterbox into a TV screen, so TV manufactures developed their own compromise: stretching. If you have a new HD set and have a standard image to show, the set can stretch it to fit the new wide screen…and in doing so add 30 pounds to every actor or actress, distort the image, and mess up the cinematographer’s composition. You’d think this would be something any viewer would object to, but go into any TV store and you’ll see one stretched image after another. Go into any sports bar and you’ll see more of the same. In fact, we were shocked recently to go into a Sushi bar and see a nice non-stretched 1.77 HD image TV program with 1.33 aspect commercials, just as it was meant to be…at least in the world of broadcast television.

So that’s the story. It’s a compromise, and a poor one. But there are solutions! You can still see a 2.35 wide screen movie letterboxed inside your 1.77 screen. Several projector manufacturers are now making equipment designed to utilize the anamorphic images found on some DVDs and make them fit a real 2.35 screen. When this is done with HD DVD or BluRay DVDs, the result should be real, honest to goodness, 2.35, ‘scope, Panavision, CinemaScope, Technirama images on your home screen. That’s your own, home, 2.35:1 aspect ratio screen! And what to do about 1.85 or 1.33 material? How about motorized masking curtains that make your screen the right shape for every format. It’s available. Today. From Platinum Home Theaters.

If you’re interested in taking the ‘wide view’, give us a call, and we’ll help you do it. In fact, we look forward to it!

5.1 surround? 7.1 surround? Bah! 10.2!!!!

I've heard the future of audio, and it is 10.2!

We've all by now heard of 5.1 channel surround, and the greater percentage of home theater sound systems are capable of playing that format. Most of today's home theater receivers are capable of 7.1 channel surround, though very few films are mixed with 7.1 channels. But what I heard goes beyond 5.1, beyond 7.1, to 10.2 channels.

Before you groan thinking "I can't put 3 front speakers where I want them, how am I ever going to place 12?", we have to go through a little analysis.

The logic goes: everyone can hear the improvement that stereo has over a single speaker mono. Similarly, the improvement between 2 channel stereo and 5.1 channel surround is also unmistakable. If you follow that line of progression, you'll notice that every time the channel count is doubled, the improvement is unmistakable. So, the next logical step past 5.1 is 10.2 channels…not 7.1, which would be an incremental step.

The Sound

The goal of all surround sound systems, from early 4 channel (Quad) systems to present day 7.1 channels is to wrap the listener in an immersive soundscape. It could be for ambience sound support of picture, or it could be used to provide a new perspective, such as a "front row" position at a concert, or a prized seat within the band itself, a position simply impossible to purchase a seat for. To a considerable extent, 5.1 channel systems do that, and create a sound space that wraps the listener in 360 degrees of sound…in a horizontal plane. So long as the speakers are mostly aligned for that horizontal 360 degree wrap, the sound field will be a thing of its own, a creation of a sound field, not the re-creation of an acoustic space.

The System

Enter 10.2 channel surround. Research has shown that the more precise the directional content of sound is, the more we perceive it as "real". What that means is, if you want a sonic image in a particular location, you need a speaker there. Early research into what became "stereo" seemed to indicate that for a 360 degree sphere of sound, you need a 360 degree sphere of thousands of speakers. Lacking that ability, compromises could be made that achieve most of the effect with far fewer speakers. 10.2 is the next logical step. Rather than limit the sound field to a basically horizontal plane, it adds the element of elevation with two high front speakers, and adds two forward side channels between the listener and the L and R speakers, and adds a single rear speaker directly behind you, along with a second subwoofer channel.

That's how 10.2 differs over 5.1, but what about 7.1? Here's a comparison:

	5.1	7.1	10.2
Left/Center/Right	yes	yes	yes
L-surr/R-surr	yes	yes	yes
L-rear/R-rear	no	yes	no
L-side/R-side	no	no	yes
L-high/R-high	no	no	yes
LFE-1/LFE-2	no	no	yes

Now, before you look at the chart and say "Look! 7.1 offers something 10.2 doesn't!", look closely. No, 10.2 does not have a Left and Right Rear, but keep in mind that Lr/Rr systems cannot reliably place a sound directly behind you. To do that they depend on a phantom image between two speakers, which only will exist if you are equidistant between two speakers playing exactly the same sound. That phantom image is fragile. Remember stereo? If you don't keep your head locked on the center-line between L and R, you won't have that firm center image of a vocalist. That means stereo has a small "sweet spot". Placing a center speaker between L and R creates a solid center, regardless of listening position. The rear speaker in 10.2 does exactly that, but behind you. The function of Lr/Rr from 7.1 is maintained by placing sound between Ls and Rear, for example. From a surround standpoint, 10.2 works like 7.1, but with a palpable rear image. That "no" in the Lr/Rr 10.2 column could really be a "yes".

What about two subs? Didn't you think subwoofers were omni-directional? Turns out, that's only true to a degree. Having two LFE channels adds dimensionality to bass while preserving the advantage of multiple subwoofers from an acoustic standpoint.

So, that's what it is. Impressed? Want to actually hear 10.2? You will have to take a little trip to San Antonio, TX. There's where you'll find Bjorn's (just Bjorn's) (http://www.bjorns.com) and their Ultimate Home Theater Experience demo room, with the only 10.2 system in a retail space. And it's a very special room and system, designed personally by Tomlinson Holman (inventor of THX, and the one who named 5.1 channel surround), and calibrated by him. In fact, he supplies the demo material, complete with his own personal introduction. The demo includes a marching band, orchestra (from both the audience perspective, and from a perspective within the orchestra) and a demonstration of the systems ability to reproduce the acoustic space of a large hall. One orchestral segment is the final few minutes of Aaron Copland's 3^rd Symphony…an presentation so involving, so immersive, that it brought us to tears…quite literally. The final segment is a very fun 10.2 mix of a Herbie Hancock piece, with lots of electronic pings, fast multichannel pans, all to a lively bit of jazz. For storing the 10.2 material, there was a computer with Firewire audio interfaces, and a bit of software for playback.

There is no video to go with 10.2 at this time. In fact, the material available in 10.2 is limited to the demo selections, and possibly others from Holman's TMH Labs, the sole supplier of 10.2 at this moment. Of course, the new Blu-ray Disc has all the capacity needed for HD picture and 10.2 channels of audio in PCM or DTS (which supposedly can support up to 2,000 channels!). There's a bit of a problem getting 10.2 out of a player right now, but providing a bit-stream output is a start.

So, you want one, right? So do I! And, quite honestly, if you don't mind waiting for more music, or even better, have the budget to commission 10.2 recordings, Platinum Home Theaters would be more than happy to build a system for you…right now. We'll also be happy to arrange for and produce those recording sessions for you. Of course, when we say budget, it's not for the squeamish. But if you REALLY want immersive audio, this is THE way to get it.

There is simply no way to describe the experience of 10.2 in words. I know, because I've been trying to for several years. You just need to pop for a weekend in San Antonio. Bjorn's is a short cab ride from the airport, and downtown San Antonio is only about 10 minutes away from the store, with its picturesque River Walk, dinner cruises around the narrow canals, restaurants with live jazz, and world class hotels. Make a weekend of it…but the highlight, I promise you, will be 10.2.

Stand by…10.2 will get here. It's already had a start of the best part of a decade. We just need to wait for those other 5.1 and 7.1 slow-pokes to get out of the way!

Blowing a Brain Breaker

Every so often I read or hear about something that trips an internal circuit-breaker in my brain. That breaker is usually tripped by an urban legend, hoax, or flat-out un-truth. Something so off the wall, so out-there, so completely implausible that it overloads brain circuits and trips a brain breaker. You get what I mean.

Here’s the latest. I hesitated even writing about this, as merely doing so propagates the myth, but better to inform than not, so here we go. It’s called the HiFi-Tuning Fuse. That’s right, a fuse. The typically cylindrical object that goes into your gear on the power-line side of things that prevents the unit from catastrophic melt-down in event of some sort of failure. The same fuse that almost never blows, and if it does, can be replaced for about $1. Only this fuse costs a bit more: try $40-$50. For one. Of course, it’s a very fine fuse, hand-made in Germany with the finest of materials, ceramic, silver, and gold. That’s not the problem, no doubt it’s well made. It’s the claims that it makes a “night and day” improvement in sound!

A fuse is simply a piece of wire that is designed to melt when a certain amount of current is passed through it, encased in a protective package. There are variables that usually address how fast it blows when an over-current situation occurs. Slower is good if you get momentary intentional over-current conditions that you don’t want to blow the fuse. Fast is better if you only expect over-current conditions when there’s a critical failure, and want to quickly protect other devices in the circuit. By its very nature, a fuse must have a small resistance in it so that it gets hot enough to melt the conducting wire inside. The wire itself is usually that resistive element. However, the net voltage drop across a fuse is extremely small, usually equivalent to many feet of wire. And, it should be said that these days the time it takes to blow a fuse is an eternity compared to how fast solid state devices can blow up. The joke is, the transistor blows out to protect the fuse. It does happen.

That’s about it. Nothing more, nothing less. So how can this be a problem? I don’t rightly know. But the testimonials on the web site for the HiFi-Tuning Fuse seem to indicate an audible improvement when they are installed. For that to actually happen, the new fuse must have change something electrically in the circuit. It must have different electrical properties than a standard fuse. What could these be?

First is resistance. A fuse must have some resistance to work as a fuse. The current causes the fuse wire to heat and melt...and that happens because of a small amount of resistance. It’s very small, though. For example, a 2A fuse run at 2A will have about a half volt drop across it. Your power line voltage swings around more than that on a daily basis. Oh, and lets not forget that 60Hz power line voltage changes direction and thus instantaneous voltage continuously…at a 60Hz rate.

Next is inductance, again very small. In fact, the power transformer the fuse is in line with has much more. There are no published figures, but as you will see, even a few mH of inductance won’t matter in the long run. Read on.

Last is capacitance. There are also no published figures, but it can be assumed that it is quite low, or a fuse would produce AC leakage, not a good thing. Again, insignificant.

So much of electrical properties of fuses. What about the “audible effect” they have? Lets consider where they are in a circuit. A fuse is usually placed in line with the AC power cord, just ahead of the power transformer or power supply. No audio, video, or computer circuit uses 60Hz AC power line voltage directly. It must first be changed to one or more DC voltage power supplies. To accomplish this in a simple analog power supply, you need a transformer to step-down the power line voltage, then a rectifier to change the AC to DC, then a filter to smooth off the resulting ripple, then a regulator to further smooth and stabilize the DC voltage. What you’ve built in a power supply circuit is something that is, by nature, designed to ignore fluctuations of voltage on the power line, first as 60Hz, but beyond that, voltage variations, impulses, sags and surges. Within limits, a well-designed power supply will keep its equipment running even during a 20% brown-out. So whatever variation a fuse introduces is more than compensated for in the power supply. Switching power supplies are used in a lot of equipment today to eliminate or reduce the need for large power transformers, but they serve the same function…produce a stable, smooth, noise-free DC voltage regardless of power line frequency or voltage fluctuations. (Are you starting to question the need for power conditioners? Hmmm!) By the time the power line AC is converted to regulated DC, the miniscule effects of power cords, fuses, and hospital-grade AC plugs are long since swamped out.

That’s my electronics theory on it. A fuse can’t have an effect on the sound or picture of a piece of audio or video gear. Now here’s my challenge:

If someone, manufacturer or otherwise, would like to send me a sample of their fuse to test in my equipment and lab, I will do so and report on the results. If it is, as claimed, a “Night and Day” level improvement, I’ll not only say so on this blog, but I’ll also sign up to become a dealer for the product, and advertise it for free on my web site. However, if it does not live up to the claims, I’ll also say so here. I’ll even return the sample, postage paid. I will take every precaution during testing to insure the fuse is not blown.

To be completely fair, the manufacture’s web site on this high end fuse makes no direct claims as to what it does, only that it is a precision manufactured item, which not doubt, it is. The claims are in the form of testimonials from reviewers and users. Care to win over a skeptic?

There it is, the gauntlet is laid down. Not as dramatic as the “Amazing Randy’s” challenge about cables, but laid down none the less.

Any takers?

Oh, and by the way, the War is over...

In what some now think was a very predictable outcome, HD-DVD has died, and Blu-ray is the winner. Since it's been covered elsewhere, here's a link:

Engadet Story

So what now? Are we done for good? Never!

Now that we know what disc based HD format we'll be using, there are still lots of problems to solve! Here are some:

1. Player control - most Blu-ray players are sluggish to respond to remote controls. In the old days (yes, way back!) early VCRs, particularly Betamax machines, responded instantly to a remote control button press, giving the user a feel of control. Scanning back for a missed piece of dialog was immediate. And the remotes themselves made sense...simple, and easy to understand, not like the current glob of black buttons on a black remote with dark gray lettering.

2. Picture improvement - What??? Sorry, folks, Blu-ray isn't the be-all and end-all. In fact, it's got quite a ways to go. For some time my personal reaction to HD of almost any flavor has been consistently "Why isn't this sharper, cleaner, lower noise, just plain better?" Whether it's been intentionally hobbled to limit the quality available to the consumer, or it's still a storage capacity thing, there are still many aspects of HD that 35mm film beats. And, digital theater projection is moving to 4K (1080p is essentially 2K). Down the road, might we see some sort of High HD consumer format? That's a subject for another post, though.

3. Lower the hardware cost, already! Blu-ray's two limiting factors to a hands-down win a year ago where second to market (can't help that now) and competitive hardware cost. An HD-DVD has always been less expensive to buy, and that's a problem still. When will we get the $149.95 Blu-ray player? Oppo, are you listening? How about the Oppo up-converting, all format playing (including SA-CD?) Blu-ray supreme player? I'd pay a lot more than $149 for that!

4. Then there's the non-disc HD content competition. Most of us still don't accumulate thousands of movies. We recognize that most of what Hollywood produces isn't worth owning, but we might subject ourselves to a one-time, low cost viewing, otherwise known as a rental. Yes, we can go to the video store and get a disc, but how much easier it would be to stay at home, not have to deal with the store's strange lack of organization, already checked-out discs, store personnel with piercings through every body part, huge check-out lines and late fees? Much. And that is rapidly becoming a viable option from Apple via Apple TV, and others. We won't have the quality of full 1080p for a bit yet, but that's a bandwidth thing, and bandwidth does seem to keep going up. If on-line rental via a set-top device is as cheap as a physical rental, almost as fast as a trip to the store, and has at least 720p quality, the convenience factors will win, and disc rental will eventually loose volume, stores will close (they are already closing), and physical rental will get harder which will avalanche on-line rentals forward. From a studio standpoint, if you don't have to produce physical materials, it's way less expensive to distribute your content. I see non-disc based distribution as being the way of the future, and your dedicated Blu-ray player becoming a dinosaur in as little as 5 years. And while that may not be enough to influence your purchase now, in a few years it will. Look for Apple TV or the like with increased capabilities like 1080p and multichannel sound and a built-in Blu-ray transport. You know it's coming...

All of that said, the Blu-ray win is welcome. We have a single standard, which we should have had all along. And HD is a definite improvement over standard video, both in picture and sound.

So, for the first time, we have a recommendation: buy a Blu-ray player, plug it into your HD home theater system, and enjoy.

Don't forget that to enjoy optimum picture and sound in your HT system of any size or type, you should have it professionally calibrated. Call Platinum Home Theaters for details.

The Re-Equalization Debacle…The "Industry" shoots itself in the foot…again!

If the term "Re-Equalization" is new to you, hang on for a minute...it's something you need to know, and we'll explain it, and the problems surrounding it as a feature in your receiver or Pre/Pro.

Simply, re-equalization is a tonal correction that needs to be applied to film soundtracks that are mixed for a large theater, but played in the home. Large theaters are equalized to the industry standard "X-Curve", which deliberately rolls-off the high end in an attempt to correct for the problem of speakers sounding to bright in large rooms. However, the "X-Curve" is actually in error, and applies too much roll off. Dubbing stages used to mix film soundtracks are equalized to an extended X-curve, and sound mixers push highs to compensate for the overly aggressive roll-off. As a result, when film soundtracks are played back on home systems with reasonably flat response, they sound too bright. Re-Equalization compensates for this anomaly. Re-equalization is part of the THX specifications for home theater equipment, and was developed by Tom Holman as part of the original Home THX specification set.

Today there are several variants on the idea (Denon has "Cinema EQ", for example) but the concept remains misunderstood. Even Denon's description of the reason their own Cinema EQ is needed is incorrect. They claim it is required because theater speakers are placed behind the screen which causes high frequency loss, but home speakers are not. In reality, 'screen loss' is compensated for elsewhere in theater sound systems, and does affect the mix. The real reason Re-Equalization is needed in home theater systems has to do with acoustic differences between large and small spaces, and the effect they have on sound systems. Recall that film soundtracks are mixed in large "dubbing stage" theaters, and thus the soundtrack is created specifically for the characteristics of that size space.

Some form of Re-Equalization is necessary in home systems if film soundtracks are to sound properly balanced and not overly bright. However, other material such as TV programs are mixed in smaller control rooms, which match the home environment more closely. Re-equalization isn't required for that material. So, on the surface, if you only watched movies on your DVD player, selecting it on your AV receiver or Pre/Pro could also automatically select re-EQ, and you might think you'd have the problem licked…but you'd be wrong.

In its inimitable style, the entertainment industry has pointed their shotgun once again at their own feet and pulled the trigger. With tens of thousands of films on DVD now, and with the normal procedure being to directly transfer the original soundtrack without modification, re-EQ would seem to be required for every one of them. But in the last year or so some DVDs have produced with re-EQ already on them. Applying re-EQ in the receiver would apply it a second time, which would result in a very dull presentation of the soundtrack. Some of these DVDs indicate in a set-up menu that re-EQ has already been done, but some do not. Even some high def discs have been re-equalized, some have not. How are we supposed to know? A fine-print notice buried in a set-up menu will hardly grab most viewer's attention, even if they did know what it meant. That means the average consumer won't know there is any action they need to take for optimum presentation. Then there's the DTS soundtrack…which has the reputation of being "re-mastered for home video", whatever that means. If directors only knew what was happening to their finely crafted soundtrack, they'd surely spontaneously combust.

We had a de-facto standard…re-EQ for all film soundtracks, no re-EQ for everything else. Now we have growing ambiguity, and as time marches forward, little chance of a fix. And it's even more frustrating knowing that the Dolby Digital audio format has within it a status bit designated for a re-eq indication…which by extension, could be used for an automatic re-equalizer trigger. But it's never been implemented, possibly due to industry rivalry between Dolby and THX…but that's conjecture…I think…but it doesn't matter really, because the result is the consumer is the one taking the beating in the form of sub-standard audio. And all of this continues in the new high-definition soundtracks found on HD disks. The Re-EQ debacle is, in fact, worse than ever.

What do we do? Assume that up until a year or so ago, re-eq is required for film soundtracks. For recent disks of any type, you need to research each one to discern if Re-EQ is required on your part, or if it has already been done on the disk…that's if you can. And finally, use your ears. If it sounds dull, turn of re-EQ. If it sounds bright, turn re-EQ on. And to that statement we do mean to imply that you need to get out the manual to your receiver or Pre/Pro, find the Re-EQ (or similar function) feature, and learn how to quickly turn it on and off, and at least find out how to tell if it's on or off.

Once again, along with the aspect ratio mess, the entertainment industry has done a major disservice to the very people that support it…us.
