8. FILTER switch
Use this switch to set the crossover frequency for the internal LOW PASS filter and for the HIGH PASS filter of
LEFT and RIGHT outputs. Choose the crossover frequency by your taste or music genre, or according to the
type of satellite connected.
The crossover frequencies vary between models: 125 / 160 Hz for S10A, 100 / 160 Hz for S12A and S15A, 80 /
125 Hz for S18A.
9. LEVEL control
Rotary level control: it attenuates the level of the signal sent to the subwoofer’s speaker. The attenuation
ranges from “0” fully closed (the signal is completely attenuated) to “10” fully open, nominal level (the signal
is not attenuated in any way, so is fed to the internal amplifier at the same level at which it arrives on input).
10. SIGN/CLIP indicator
GREEN LED illuminates to indicate the presence of the signal at the built-in amplifier input.
RED LED illuminates when the internal amplifier's output is limited. When this LED flashes continuously you
should reduce the input signal level.
11. PHASE 0° / 180° switch
This switch reverses the polarity of the subwoofer. Depending on the placement of the subwoofer relative to
the full-range satellite speakers, you can get a better low-frequency response in the room if you reverse the
polarity of the subwoofer’s signal. Listen in different positions of the venue to find which is the best sounding
setting.
NOTE: ALL SUBWOOFER SPEAKERS MUST BE HAVE THE SAME POLARITY. If you note a lack in lowest frequency
range using more than one subwoofer, probably you have one of them out-of-phase respect to the others. Be
always sure that all these switches are in same position.
12. ON indicator
GREEN LED: when lighted indicates that the amplifier has been turned on and AC power is available.
13. POWER switch
Speaker is "ON" when the switch is in the "I" position. Use this switch to set the speaker power to ON or OFF.
NOTE: When you shut down your equipment, turn off the speaker first. When powering up, turn on the
speaker last.
14. LINE VOLTAGE selector
This switch sets the AC voltage line of your country (usually it is set by factory and isn't necessary to change
it). The 115V setting is for mains line in the range of 100-120V~ and 230V setting is for mains line in the range
of 220-240V~.
WARNING: an incorrect setting of AC LINE VOLTAGE could damage seriously the internal electronics!
15. FUSE holder
Here is placed the mains protection fuse.
REPLACE THE PROTECTION FUSE ONLY WITH SAME TYPE AS SHOWN ON THE PRODUCT.
IF AFTER THE SUBSTITUTION, THE FUSE INTERRUPTS AGAIN THE APPARATUS WORKING, DO NOT
TRY AGAIN THEN CONTACT THE PROEL SERVICE CENTER.
