configuration of your listening environment, the placement
of the unit, and your seating arrangement. Due to the way
bass sound waves develop in different rooms, there is no rule
of thumb for setting phase. For instance, if your room has
a peak at the subwoofer crossover area, you may wish to
set the phase so the actual acoustic outputs of the subwoofer
and main speakers are out of phase. Experiment, try dif-
ferent settings and be patient.
Power
The Auto/On/Standby switch controls Descent i's energy
saving feature. When set to 'Auto', the Descent i will turn
on when a music signal is detected and off when there is
none. The 'On' setting prevents the Descent i from enter-
ing energy saving mode. The 'Standby' setting forces the
Descent i into energy saving mode. While set to 'Standby',
the Descent i will not operate.
25Hz & 50 Hz Level
The 25Hz & 50Hz Level knobs significantly adjusts fre-
quencies where peaks and dips of different amplitudes
often manifest in real world environments. The ideal set-
ting is dependent on room size and construction, system
configuration and personal preference.
High Pass Filter: Out
The High Pass Filter: Out control filters the signal output
from the Right Out and Left Out connections.
Status Light
See descriptions of the status light on page 8. The top con-
trol panel status light functions identically to the back plate
status light.
