In reaction to the fact that the 6 channel pan on Avia appears to be flawed, I have authored 2 DD test tones which will allow people to test the level of LFE vs the level of rerouted bass from other channels. The idea is that the 40hz sine wav in any channel, with the speakers set to small, will be rerouted to the sub. Since it is the same freq, coming from the same sub, with the meter in the same position- the only variable in the level of output would be the amount of signal being sent by the preamp. If the decoding is done correctly, the main channel tones and the sub tone should be within 1 db of one another. 1) dd140hz1.wav: A 40hz tone at -20 which repeats in each of the 6 channels, 5 seconds at a time (Left, Center, Right, Left Surround, Right Surround and LFE). The exact same wav file was imported for each of the channels- so it is absolutely identical. Because the LFE track in a dolby playback system (if configred correctly) boosts the LFE by 10db- a correct playback should keep the tone even until it reaches the LFE, where it will jump by several DB (approx 10). If your final tone does not jump obviously- there might be an incorrect setting in your processor. 2) dd140hz2.wav: A 40hz tone at -20 in the mains/ -30 in the LFE which repeats in each of the 6 channels, 5 seconds a time (Left, Center, Right, Left Surround, Right Surround and LFE). The exact same wav file was imported for each of the main channels- so it is absolutely identical (aside from the LFE tone which is 10db down- but all tones were generated using professional tone generation software). Because the LFE track in a dolby playback system (if configred correctly) boosts the LFE by 10db- a correct playback should keep the tone even through all 6 speakers. If the final tone drops off significantly in your system, there is a LFE error. -The tone is 40hz sine wave- so for this experiment you will have to have your speakers set to small (the whole point is testing rerouted bass vs lfe!) and you might want to start out with your x-over point around 80, and if you usually run lower- work your way down and see what effect it has. - Tones are 5 megs a piece, so broadband is probably a must. - These two files are DD encoded wav files. It is possible to burn them to a CD, and play them in a cd player or a dvd player with a digital output- and get DD. This does not work with every player. However- if you have a PC with Spidf output, you should be able to use windows media player to play the files and get DD on your processor (it worked for me with the Maudio Audiophile card). Note, if you try to play these back in the analog domain or if your player can't deal with the format you will get very displeasing noise! Be careful, turn the volume all the way down until the processor confirms a DD lock! If anyone has any questions- feel free to post.
