AC-3 STATUS displays the current status of incoming AC-3 data. The
displayed items are not user adjustable.
COMPRESSION enhances the intelligibility of Dolby Digital material at
low volume levels (-6dB or lower). When set to AUTO, this control auto-
matically limits peak signals and boosts low level signals. The amount of
compression increases proportionately as volume is decreased. This is quite
useful when listening to Dolby Digital soundtracks at low output levels.
When set to ON, full compression is applied, regardless of volume.
RE-EQUALIZER equalizes the left, center, and right channel outputs to
match the overall frequency balance of the original recording. Without this
re-equalization, many films and some television programs will sound too
bright.
SURROUND LEVEL controls the volume level of the side and rear speakers.
Although we have selected a default value, the correct setting will vary with
each recording, the room, and your personal taste.
REAR DELAY OFFSET is an additional delay added to the rear channels
when listening to LOGIC 7 and MUSIC SURROUND. This delay increases
the apparent size of the listening space by increasing the rear delay time.
Feel free to experiment to find the setting that works best.
LFE MIX LEVEL allows separate level attenuation of the LFE channel,
which is ultimately mixed to the subwoofer output. As the bass from as
many as five other channels is added to the LFE, it can significantly raise
subwoofer output levels — and create the risk of damage to a system.
Careful adjustment of this parameter will allow you to achieve proper tonal
balance and reduce the risk of damage.
SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the
normal subwoofer level is set during the calibration procedure, with some
recordings it may be desirable to increase or decrease this deep bass level.

CUSTOM
This Effect, available only in DC-1’s equipped with Dolby Digital process-
ing, enhances playback of Dolby Digital music recordings, or Dolby Digital
film soundtracks with strong musical content. This effect contains many of
the features found in 5.1 LOGIC 7, with settings that are more appropriate
for music. 5.1 Music
