LISTENING MODE MENU OPTION & PARAMETER DESCRIPTIONS (continued)

Note the following:

•Dolby Digital Surround EX decoding cannot be engaged unless both side and rear speakers are present.

•When the Shift command bank is activated, pressing the remote control DOLBY button while a 5.1-channel Dolby Digital source is present activates the Dolby DIGITAL EX or Dolby DIGITAL listening mode. Subsequent presses adjust the EX DECODING parameter, cycling through the AUTO, ON, and OFF settings.

This parameter is available in 5.1 PLIIx MOV, 5.1 PLIIx MUS, and DOLBY DIGITAL (EX) modes.

FRONT STEERING OFF, MSURR, MUSIC, FILM

Adjusts front steering between the front left, front right, and center speakers. When set to FILM, maximum front steering is applied to the center channel. When set to MUSIC, moderate front steering is applied. When set to MSURR, minimum front steering is applied. When set to OFF, no front steering is applied. You should set this parameter to FILM for film and broadcast sources and to MUSIC, MSURR or OFF for music sources. Available in L7 TV, L7 MUSIC, L7 MUSIC SURR, 5.1 L7 TV, 5.1 L7 MUSIC, dts L7 MUSIC, , and 5.1mc L7 MUSIC modes.

INPUT BALANCE L< to <> to >R

Controls the balance of the selected stereo analog audio input connectors, compensating for audio input sources with audible channel imbalance. Available in PANORAMA mode.

LFE OFF, -30.0 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. Available in all 5.1 Dolby Digital modes, except 5.1 2-CHANNEL, 5.1 MONO LOGIC, 5.1 MONO SURR, and 5.1 MONO. Also available in 5.1mc L7 FILM, 5.1mc L7 MUSIC, 5.1mc THX, 5.1mc THX MUSIC, 5.1mc STANDARD, 5.1a BYPASS, DTS L7 FILM, DTS L7 MUSIC, DTS THX, DTS THX MUSIC, and DTS modes.

LFE MIX -20.0 or -10.0 to +0.0dB

Controls the output level of LFE information – the .1 channel in a 5.1-channel or 6.1-channel input source – that is sent to the audio output labeled Subwoofer. Low frequencies from up to seven other channels may 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. Available in all DTS and all Dolby Digital modes except MONO modes (5.1 MONO LOGIC, 5.1 MONO SURR, 5.1 MONO), and all 5.1mc modes except 5.1mc STANDARD and 5.1a BYPASS modes.

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.
