EQUALIZATION SETTINGS AND ADJUSTMENTS
The preamplifier provides 3 ways to modify the frequency response (equalization) for particular listening situa-
tions. These equalization are in addition to the room equalization and room resonance adjustments made in
the speaker setup menu. Pressing the EQ button consecutively on the remote control will step through the
preamplifier’s user EQ selections. To quickly select an EQ, press EQ, then the EQ number. Equalization is
not available for DVD-Audio, Direct, or LtRt Modes.
The available user EQ’s are defined as follows:
0 Flat - No equalization applied.
1 Variable - User designated EQ settings. To adjust the variable EQ
from the OSD, highlight the Variable EQ selection from the Z1 Operation
- Theater Zone Menu. Press the ENTER button to access and adjust
the variable EQ settings as shown. Bass and treble level adjustments
can be made using the LEFT and RIGHT arrows. Your preamplifier
allows the designation of the frequency at which the bass and treble
adjustments occur.
LFE gain can be adjusted. Note that this affects only the separate LFE
(.1) track available on Dolby Digital and DTS material it has no effect on
the reproduction of normal bass from the front, center, or surround
channels.
The dynamic range (Dolby Night-time mode) can be limited for late night
listening while processing Dolby Digital or DTS bitstreams.
2 Loudness - The human ear's frequency response varies with volume
level. At high levels it has relatively flat response, while at low levels its
sensitivity to high and low frequencies are reduced. The loudness equal-
izer is designed to cancel the ear's frequency response anomalies to
provide consistent tone at all volume levels. Note that you will hear little
difference using the loudness control at high volumes as it has its greatest
effect at lower volume levels.
3 Vocal - Frequency gains have been cut on both the high and low end for vocals only listening. This is
useful for late night listening as it allows you to hear the dialogue, but reduces the volume of sound effects
which might disturb others. Unlike Dolby Digital/DTS nighttime modes, the vocal filter is effective for all source
material including PCM and analog.
This equalizer is also effective in reducing the vocal boominess often associated with FM talk radio. Some
crackly old movie soundtracks will have improved clarity with the vocal filter on.
The table below outlines how the various EQs can be applied in each audio mode. To manually select an
EQ, press the EQ button on the remote control followed by the EQ#.
