Lexicon MC-4, User Manual

MODE ADJUST
MC-4
5-33
MASTER LEVEL
–5dB to +5dB
Adjusts the output level of 2-channel Logic 7-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.
LFE MIX
–20.0dB or –10.0dB 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 audio output
labeled Subwoofer. Low frequencies from up to seven other chan-
nels 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 sub-
woofer overload. When the speaker setup does not include a sub-
woofer, LFE information is mixed into speakers for which the cor-
responding
CUSTOM SETUP menu parameter is set to FULL or to the lowest
crossover points.
LISTENER POS
–127 to +127
See “PANORAMA CALIBRATION” on page 5-12 for more informa-
tion.
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
–25dB to +25dB
Applies low-frequency spatial correction to the input signal. This
correction is applied to uncorrelated input signals below 60Hz.
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 audio output connectors labeled Center,
Sub, 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 multichannel output signals. Instead, an out-
put-specific parameter appears. For instance, the Mono listening
mode menu includes a SUB LEVEL parameter.
