Listening Mode Menu Parameter Descriptions

(continued from page 5-37)

LFE

OFF, -30 to +12dB

Controls the output level of the Main Zone audio output connector labeled LFE. The OUTPUT LEVELS menu does not include the LFE parameter unless an LFE subwoofer is present.

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 source – that is sent to the Main Zone audio output connectors labeled Subwoofer L/R and LFE. 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

Compensates for primary listening positions that are not centered between the front left and right speakers. Each increment within the –127 to +127 parameter range represents about one-third of an inch. Refer to the Calibration section that begins on page 5-12 for more information about the LISTENER POS parameter.

Note:

The LISTENER POS parameter range might extend past the location of the front left and right speakers.

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 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. The full parameter range might not be available depending on the BASS RT and SIZE parameter settings.

CAUTION Setting the BASS RT, MID RT, or SIZE parameters to a high value may produce undesirable or damaging audio.
