Using in-band pink noise (meaning 200 to 2kHz), set the reference level for each of the 5 main channels to 85dB SPL (or other reference level desired). You must calibrate each channel individually with the others muted. Set the level of the LFE channel of the subwoofer to 4dB above the chosen reference level (89dB if the reference level is 85dB).

No. You must hook the Xbox optical output to some device capable of decoding the AC-3 digital audio. There are NO EXCEPTIONS. You need either an AC-3 capable receiver or an AC-3 capable PC sound card with optical input.

This is typically caused because the home theatre receiver is not in Dolby Pro-Logic or Dolby Digital Surround mode. Different brands of home theatre receivers have different methods to put the system in this mode. It is usually controlled from the remote and often called "listen mode" or "mode". Also occasionally you’ll encounter a movie with little or no surround information on the soundtrack. The older the movie the more likely this to be the case.

No, the HDMI outputs on the Movie Player and the Movie Player 2 carry video and PCM stereo audio only. When using HDMI for video, you can use digital coaxial, digital optical, or analog stereo outputs for audio. No. The DVD CCA License does not permit the use of RGBHV video output during DVD playback. The Kaleidescape Movie Player 2 supports both HDMI and component video (YPbPr) for high-quality video output.

Dolby Digital, Dolby Pro Logic II and DTS are all supported and processed. Remember all audio is processed by the Cell and developers can use whatever audio codecs they want…so this is only the beginning.

of a few years ago, most consumer off-the-shelf systems feature either 5 identical speakers or 4 identical speakers with a center channel modified for better placement on top of the television. For a home theater system designed primarily for watching movies, the center channel may be of dubious quality and design though. In many older (circa 2000 or so) consumer music-only surround system, the front speakers may be matched direct radiators and the rear speakers may be dipoles (see 1.10).

That's the steering system of the Dolby Pro Logic decoder in your receiver extracting the rear channel information. Because the process is very phase dependant, the swishing sound (phase shift) can be evident during action scenes with a lot of panning. The latest Pro Logic II is less susceptible to this effect.

Your film will be shown in Standard Definition in stereo or mono with an aspect ratio of 4:3. So you may shoot in HD, in widescreen, or in surround sound, but the film will not be projected that way. We require you to submit a Standard Definition, letterboxed, stereo or mono version of your film—anything else can lead to problems during our mastering process.

This is a slightly touchy subject. My original intent in building this site was to celebrate the Dynaco company formed by David Hafler, and crewed by talented folks such as Ed Laurent, Wade Burns, Joe Sparacio, Jim Elliott, Sid Lidz, Bob Tucker, Bill Phillips, Harry Klaus, Erno Borbely, John Ferranti, Doug Hercus, Richard Pley, etc. etc. I wanted to provide detailed info on the equipment they designed, supported, and serviced, right through the end of the company in 1980.

Ideally, surround speakers should be either wall-mounted or stand-mounted to either side of the couch or primary listening area, from one to six feet higher than seated listeners' ears, and slightly forward or rearwards of the listening area if you wish. Axiom's Quadpolar surrounds are especially versatile and can yield excellent performance with stand or wall-mounting to the rear as well as at side locations. (see our dedicated stands for the QS Surround speakers in the Store).

Thanks to the increasing power and dropping cost of signal-processing chips, sound that appears to come from around the listener is now possible with just two speakers. These audio processing systems, often referred to as "virtual surround," require that the listener be positioned in a specific "sweet spot" in front of the two speakers. As a result, they cannot substitute for multiple speakers in home theater applications.

The Boostaroo Revolution's patent pending circuit is an adaptation of cross feed circuitry. A cross feed circuit combines parts of the left stereo channel and the right stereo channel. This combination of sound fields alters how your brain perceives what you are hearing. This will make the music seem to come from all around you, rather than just regular left and right. This effect is more apparent in higher grade headphones, and speakers.

The DVD side of the DualDisc offers superior audio. Many DualDiscs include surround sound mixes that have been specially created during the recording process. When listened to on a 5.1 channel surround system, the result is a rich, three-dimensional musical experience.

Answer: This is a generic term for any speaker setup that includes rear speakers that receive a different signal than the front speakers. This is meant to create a 3-dimensional effect, allowing you to hear sounds behind you, just like in the movie theater. Current "surround sound" speaker setups usually feature two front speakers, two rears, a center, and a subwoofer. This is known as 5.1 (5 speakers, 1 subwoofer.

bull; A center-channel speaker (located directly above/below your HDTV) that reproduces dialog on your screen. bull; Two front (or main-channel) speakers, which reproduce most of the musical soundtrack, plus left and right spatial cues (like someone walking into the room from one side or the other).
