THX ULTRA2 SUB ON, OFF
Indicates whether or not the subwoofer connected to the audio
output connector labeled Subwoofer is Ultra2 certified. Select ON
if the connected subwoofer is Ultra2 certified and OFF if the con-
nected subwoofer is not Ultra2 certified. When ON, the CUSTOM
and THX SETUP menu BGC parameter (next column) are used to
adjust boundary gain compensation. When OFF, the BGC parame-
ter is not available (N/A).
BGC (BOUNDARY GAIN COMPENSATION) ON, OFF
Adjusts boundary gain compensation when the CUSTOM and THX
SETUP menu THX ULTRA2 SUB parameter is ON. When the BGC
parameter is ON, a highpass 55Hz filter is applied to all listening
modes and audio output connectors. When OFF, no filter is applied
to listening modes and audio output connectors. When the param-
eter setting is N/A, the THX ULTRA2 SUB parameter is OFF and
boundary gain compensation cannot be adjusted.
Note:
BGC compensates for increased bass energy that is caused by the proxim-
ity of the speakers to the listening room walls.
