6.7m). Press

The speaker distance will be shown in either units feet or metres.
Note: If inappropriate speaker delays are set, a warning will display indicating too much
time offset between Left and Right channels. The following warring will display;

THX ULTRA2
Set the subwoofer BOUNDARY GAIN COMPENSATION to ON or OFF depending on
whether you have one or two THX ULTRA2 subwoofers in close proximity to vertical surfaces.
If a listener is sitting too close to a vertical surface their perception of the low frequencies is
perceived as exaggerated. However, with The Boundary Gain Compensation filter applied to
all output channels, the bass is equalized resulting in a flatter, more accurate bass response.
Press
ENTER on the HTRM to save the boundary gain settings.
Note: Boundary Gain Compensation is only available for THX ULTRA2 subwoofer
selections.
DISTANCE BETWEEN SBL+SBR SPEAKERS
When you select two surround back speakers, set the distance between the two speakers in
between 0ft to 22ft (0m to 6.7m). This setting will give correct spacial effect of the rear
channels during THX Cinema, THX Surround EX, THX Music, and THX ULTRA2 decoding.
Press
ENTER on the HTRM to save the distance settings.
