Subwoofer master control. Turn the knob clockwise to increase volume,
or counterclockwise to decrease it.
4 GND
Press this switch to reduce or eliminate the noise of the electric ground
when connecting signal lines between multiple devices. It is very effective
in eliminating ground loops, but the actual result depends also on other
connected devices.

When it is activated, use the OUT L/R to connect two additional active
speakers.
6 PHASE
Press this button to invert by 180 degrees the subwoofer phase to easily
compensate possible phase cancellations due to venue acoustics, the
presence of multiple subwoofers, or when using not-standard phased
satellites.

unbalanced cable.
8 RIGHT INPUT

9 LINK L/R
Balanced Left/Right channels XLR-M line outputs for parallel wiring of
further active speakers.
10 OUT L/R
Balanced Left/Right channels XLR-M line outputs.
Use these outputs to connect further active speakers, whose signal is
influenced by the LOW CUT filter at 100Hz.
1 SIG/CLIP
Led lit green: input signal present.
Led lit red: Indicates the activation of the internal limiter circuit preventing amplifier
distortion and protecting the speakers against overloads. In this case, reduce the
MASTER level and that of the sound source.
