EQUALIZATION ‘EQ’
Selecting an EQ function via the remote control
- allows you to override how the audio is currently being
processed. This is where you may set the Dynamic Range to either Normal (default) or Limited for late night
listening while processing Dolby Digital or DTS bit streams.
Settings made here are intended for occasional adjustments for a particular source material. They affect all inputs
but are temporary. After turning the system off and on, the original parameters from the SETUP menus are
restored. If there are temporary settings you use often, you may wish to store them in a preset for instant recall
See PRESETS.
You may select EQ, Off ‘EQ 0”, Variable ‘EQ 1’, Loudness ‘EQ 2’ or Theater ‘EQ 3’.
The table below shows the various audio modes and how the EQ feature may be used. Under normal usage a
user would select one of these EQs to either correct or enhance their processed audio.
Note, while in ‘DIRECT’ or ‘LtRt’ (speaker selections 8 & 9) the equalizer feature of your unit is not available and
disabled (see EQUALIZATION ‘EQ’).

If your processor is used in a THX home theater environment, best results during movies may be realized using
the THX audio listening mode (see AUDIO MODES, THX). Selecting the audio mode THX incorporates Lucasfilm
Home THX Re-Equalization™, Timbre Matching™ and Adaptive Decorrelation™ to correct for the tonal and
spatial errors that occur during the translation from the movie theater environment into the home. THX Ultra2 ™
Cinema mode and THX MusicMode ™ use Advanced Speaker Array ™ (ASA). In audio modes THX Movie and
THX Music, ASA is used to perform additional processing to optimize the use of surround side and surround back
speakers in a home theater system.

Adjust LFE Level
If you have no subwoofer and you wish to reduce the low frequency effects (LFE) channel to lessen its
contribution to the bass going to your remaining large speakers. Or, even with a subwoofer, you may just wish to
reduce the overall LFE level, especially in an apartment situation. Note that this affects only the separate LFE (.1)
channel available on Dolby Digital and DTS material it has no effect on the reproduction of normal bass from the
front, center, or surround channels.
