Surround parameters @
CINEMA EQ. (Cinema Equalizer):
The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture
soundtracks. Select this function if the sound from the front speakers is too bright.
This function only works in the Dolby Pro Logic, Dolby Digital and DTS Surround modes. (The same contents are set for all operating modes.)
D.COMl? (Dynamic Range Compression):
Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night,
or whenever the maximum sound level is lower than usual, the Dynamic Range Compression allows you to hear all of the sounds in the
soundtrack (but with reduced dynamic range). (This only works when playing program sources recorded in Dolby Digital.) Select one of the four
parameters ("OFF", "LOW", "MID" (middle) or "HI" (high)). Set to OFF for normal listening.
LFE (Low Frequency Effect):
This sets the level of the LFE (Low Frequency Effect) sounds included in the source when playing program sources recorded in Dolby Digital
or DTS.
If the sound produced from the subwoofer sounds distorted due to the LFE srgnals when playing Dolby Digital or DTS sources when the peak
limiter is turned off with the subwoofer peak limit level setting (system setup menu), adjust the level as necessary.
Program source and adjustment range:
1. Dolby Digital: -10 dB to 0 dB
2. DTS Surround: -10 dB to 0 dB
% When DTS encoded movie software is played, it is recommended that the LFE LEVEL be set to 0 dB for correct DTS playback.
% When DTS encoded music software is played, it is recommended that the LFE LEVEL be set to -10 dB for correct DTS playback.
