Digital bitstream indicates that it contains a mono program. This feature can process a
one-channel program into five-speaker sound, directing the signals so that dialogue
remains locked on-screen, while music and ambient effects fill the room. You experi-
ence a surround sensation, providing extra enjoyment when you watch older (that is,
pre-stereo) movies. This feature can be used for mono TV shows and movies when you
select TV, VCR, AUX, or TAPE.
Mono decoding is off.

Treble
Compensation:
–14 to +14
After
ADAPTiQ
system
calibration:
–9 to +6
Decreases (–) or increases (+) the treble sound.
Rooms with few sound-absorbing furnishings, especially those with bare
floors and walls, may sound overly shrill or “bright.” Decreasing the treble
sound can be useful. Conversely, rooms with a lot of sound-absorbing
furnishings, such as upholstered furniture, wall-to-wall carpet, or heavy
drapes, can sound “dull” and may benefit by increasing the treble sound.
Different source materials, such as DVDs, CDs or radio stations, may also
vary in the amount of treble they have.
You can decrease the treble sound by lowering this setting to a negative
value from –1 to –14. To increase the treble, raise this setting to a positive
value from +1 to +14.
Note: Completion
of the ADAPTiQ
audio calibration
compensates for
your room acous-
tics. Subsequently,
the treble and bass
controls operate
only over the range
from –9 to +6 and
should only be
needed for occa-
sional adjustments
due to source mate-
rial variations.
Bass
Compensation:
–14 to +14
After
ADAPTiQ
system
calibration:
–9 to +6
Decreases (–) or increases (+) the bass sound.
Placement of the Acoustimass
®
module affects the amount of bass you
hear. Placing the module closer to the corner of the room will increase the
bass. Moving the module away from the corner will decrease the bass.
Different source materials, such as DVDs, CDs or radio stations, may also
vary in the amount of bass they have.
You can decrease the bass sound by lowering this setting to a negative
value from –1 to –14. To increase the bass, raise this setting to a positive
value from +1 to +14.
