AV1 Mode Adjust

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 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 bal- ance 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 parame- ter is set to FULL or to the lowest crossover points.

LISTENER POS -127 to +127

See “PANORAMA CALIBRATION” on page 5-12for more information.

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.

MASTER LEVEL -5dB 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.

CAUTION!

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

OUTPUT LEVELS

MODE ADJUST (Listening Mode) OUTPUT LEVELS

Opens the OUTPUT LEVELS menu, which can be used to adjust out- put 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 accom- modate multichannel output signals. Instead, an output-specific parameter appears. For instance, the Mono listening mode menu includes a SUB LEVEL parameter.

Option/Parameter	Default Setting	Possible Settings
CENTER	+0dB	OFF, -30dB to +12dB
SIDE L/R	+0dB	OFF, -30dB to +12dB
REAR L/R	+0dB	OFF, -30dB to +12dB
SUB	+0dB	OFF, -30dB to +12dB
