Listening Mode Menu Option & Parameter Descriptions
(continued from page 5-31)
LFE MIX -20.0 or -10.0 to +0.0dB
Controls the output level of LFE information – the .1 channel in a
5.1- or 6.1-channel input source – that is sent to the Main Zone
audio output labeled Subwoofer. Low frequencies from up to seven
other channels might be combined with the LFE information to
create the subwoofer output signal, which significantly increases
subwoofer output levels. Careful adjustment of this parameter
allows achievement of proper tonal balance and reduces the risk of
subwoofer overload. When the speaker setup does not include a
subwoofer, LFE information is mixed into speakers for which the
corresponding CUSTOM SETUP menu parameter is set to FULL or
to the lowest crossover points.
LISTENER POS -127 to +127
Refer to page 5-12.
LIVENESS 30ms to 20.2s
Depends on the SIZE parameter setting. The LIVENESS parameter
adjusts the amount of effect recirculation. Higher settings mimic
more reflective surfaces and increase decay time.
LOW FREQ WIDTH -25 to +25dB
Applies low-frequency spatial correction to the input signal. This
correction is applied to un-correlated input signals below 60Hz.
MASTER LEVEL -5 to +5dB
Adjusts the output level of 2-channel LOGIC7-encoded sources.
MID RT 24ms to 24.3s
Works with the BASS RT and SIZE parameters to adjust the amount
of time required for mid-frequency information to decay below
60dB in level.
Setting the BASS RT, MID RT, or SIZE parameters to a high
value may produce undesirable or damaging audio.
CAUTION
OUTPUT LEVELS
Opens the OUTPUT LEVELS menu, which can be used to adjust
output levels for the Main Zone audio output connectors labeled
Center, Subwoofer, Side L/R, and Rear L/R. The OUTPUT LEVELS
option does not appear on listening mode menus when the
listening mode does not accommodate multi-channel output
signals. Instead, an output-specific parameter appears. For
instance, the Mono listening mode menu includes a SUB LEVEL
parameter.
