9. LEVEL control
Rotary level control: it a enuates the level of the signal sent to the subwoofer speaker. The a enua on ranges from
“0” fully closed (the signal is completely a enuated) to “10” fully open, nominal level (the signal is not a enuated in
any way, so is fed to the internal amplifi er at the same level at which it arrives on input).
10. LIMIT indicator
GREEN LED illuminates to indicate the presence of the signal at the built-in amplifi er input.
RED LED illuminates when the internal amplifi er's output is limited. When this LED fl ashes 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 rela ve to the
full-range sat speakers, you can get a be er low-frequency response in the room if you reverse the polarity of the
subwoofer’s signal. Listen in diff erent posi ons of the venue in order to fi nd which is the best sounding se ng.
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 a subwoofer out-of-phase respect the other. Be always sure all these
switches are in same posi on.
12. ON indicator
GREEN LED: when lighted indicates that the amplifi er has been turned on and AC power is available.
13. POWER switch
Speaker is "ON" when the switch is in the "I" posi on. Use this switch to set the speaker power to ON or OFF.
NOTE: When you shut down your equipment, turn off the speaker fi rst. When powering up, turn on the speaker last.

WARNING: replace the protecƟ on fuse only with same type as shown on the product.
If aŌ er the subsƟ tuƟ on, the fuse interrupts again the apparatus working, do not try again then contact the proel
service center.
16. LINE VOLTAGE selector
This selector set the AC voltage line of your country (usually it is set by factory and isn't necessary to change). The 115V
se ng is for mains line in the range of 105-120V~ and 230V se ng is for mains line in the range of 210-240V~.
WARNING: an incorrect seƫ ng of AC LINE VOLTAGE could damage seriously the internal amplifi er!
17. POWER OUT AC~ socket
Here’s where you plug in your satellite speaker’s mains supply cord. Connec ng the satellite speaker to this socket you
can switch on/off the whole system from the SW110A power switch.
WARNING: the maximum load for each socket is 4 amperes, the power out sockets are NOT protected by the
fuse.
