SOUND FIELD PARAMETER DESCRIPTIONS
74
You can adjust the values of certain digital sound field parameters so the sound fields are recreated accurately in your
listening room. Not all of the following parameters are found in every program.
■ DSP LEVEL (DSP level)
Function: Adjusts the level of all the DSP effect sounds within a narrow range.
Description: Depending on the acoustics of your listening room, you may want to increase or decrease the DSP
effect level relative to the level of the direct sound.
Control range: –6 dB to +3 dB
■ INIT.DLY (Initial delay)
Function: Changes the apparent distance from the source sound by adjusting the delay between the direct sound
and the first reflection heard by the listener.
Description: The smaller the value, the closer the sound source seems to the listener. The larger the value, the farther
it seems. For a small room, set to a small value. For a large room, set to a large value.
Control range: 1 to 99 msec
For 2ch Stereo:
■ DIRECT (Direct)
Function: Bypasses this unit’s decoders and DSP processors for pure high fidelity sound when playing 2-channel
analog sources. The AUTO setting is effective only when BASS and TREBLE are set to 0 dB.
Choices: AUTO , OFF
• When multi-channel signals (Dolby Digital and DTS) are input, they are downmixed to 2 channels and output from the front left and
right speakers.
• When “BASS OUT” is set to BOTH, or “FRONT” set to SMALL and “BASS OUT” set to SWFR, front left and right speaker low-
frequency signals are redirected to the subwoofer.
