How to Adjust the Subwoofer Settings
The Subwooofer Settings allow for optimizing perfor-
mance in the Home Theater System that relate to Room
Acoustics and Loudspeaker Characteristics. For most
Home Theater Loudspeaker Systems the default setting
will produce the best performance. Refer to the Owner's
Manual that came with the Loudspeaker, your dealer and/or
the manufacture of the Loudspeaker for recommendations.
Note: Before adjusting the SUBWOOFER SETTINGS, you
FIRST must have performed the SPEAKER SIZE,
SPEAKER TIME DELAY and SPEAKER LEVEL
Adjustments.
1. Press and hold the Front Panel SETUP Push-button ap-
proximately three seconds to enter the Setup Mode.
The word SETUP will appear on the MHT100 Front

Mc Bass Mode
When a Home Theater System contains Loudspeakers that
are refered to as Large, the Bass Management Circuitry
will steer all the Low Frequency Sounds away from the
Subwoofer and to the Large Loudspeakers. With the MC
BASS MODE set to ON the Low Frequency Sounds are
sent to both the Large Loudspeakers and to the Subwoofer,
thus increasing the total low frequency output of the Home
Theater System. The default setting for the MC BASS
MODE is OFF. Refer to figure 21 and perform the follow-
ing steps to switch it On.
3. Using the Up or Down
select MC BASS MODE from the On-Screen Menu,
followed by pressing the Left
push-buttons to active the circuit. Select EXIT on the
menu and the MAIN SYSTEM SETUP Menu will re-
appear on the Monitor/TV screen.
