DESCRIPTION OF CONTROLS
FRONT PANEL
A)
SUBWOOFER SELECTOR:
1)
Selection of type of subwoofer:
The block of switches on the left allows the
selection of the type of subwoofer. The choice is based on the size of drivers and their
acoustic load: the labels "18" "15" "46" "38" refer to the products reference. The "S"
switch must be engaged if the subwoofer's reference includes one.
B)
TOPOLOGY OF SYSTEM:
Local / Distant
: This switch modifies the crossover frequency in accordance with the relative
position of the subwoofers and the main speakers. If the main speakers are stacked on the
subs or at less than 1.5 meter (5ft), the switch must be in the Local position. If the speaker is
at more than 1.5meter (as when installed on a pole), the switch must be pressed in the
Distant position.

3)
Phase
: When depressed, this push-button introduces a polarity reversal to
compensate wiring problems or acoustical phase reversals
4)
Align:
the phase of the subwoofers relative to the main speakers can be aligned,
optimizing the system's crossover.
5)
Sub Level:
this potentiometer controls the level of the subwoofers. A center detent
indicates the nominal position. The range is from infinite attenuation to 6 dB gain.
