INPUT L and INPUT R
Line-level left and right inputs via COMBO sockets.
COMBO sockets allow you to either connect a mono/
stereo male XLR or male Jack plug.
These are balance inputs.
More details about connections are available further in
this guide.

THRU L and THRU R outputs
These 3-pin XLR outputs allow you to send the incoming
signal to amplified speakers (for instance).
3
LEVEL control knob
Allows you to adjust the sound output of your subwoofer.
Although you can turn it at full volume, we
recommend, to guarantee an optimal sound quality,
not to exceed 0 dB signals level on your mixing desk.
These settings do not affect THRU L and THRU R
outputs.

Indicator LEDs
• Power
: Lights up upon activation of your subwoofer.
• Signal
: Lights up upon detection of an incoming
signal.
• Clip
: Lights up when incoming signal levels exceed
0dB. Please make sure this LED only lights up briefly
to guarantee an optimal sound quality.

PHASE
Phase inverter switch.
The phase inversion is especially
useful when using several subwoofers
simultaneously.
Depending on the position of your subwoofers, low
frequencies might cancel each other. use the phase
inverter to fix this.
6
FREQUENCY control knob
Cutoff frequency control knob.
Allows you to adjust the cutoff frequency of your
subwoofer depending on the connected broadband
speakers.
75Hz is exact same cutoff frequency of SR series
amplified speakers.
If using SR12 or SR15A, this value is perfect to cover the
whole audio spectrum.
SR10A speakers will require you to slightly increase the
cutoff frequency.
These settings do not affect THRU L and THRU R
outputs.

Fuse
Protects the power supply module of the built-in
amplifier.
If need to replace it, please make sure the new one has
the exact same characteristics.

electrical outlet via the supplied IEC power cord.
Please make sure the voltage delivered by the electrical
outlet is similar to the voltage selector positioning before
activating your device.
