1. Power Input: Use the included power cable to
connect this input to a power outlet. Make sure
the speaker’s power switch is set to “off” when
connecting or disconnecting the cable.
2. Fuse: If the unit’s fuse is broken, lift this tab to
replace the fuse. Replace it with a fuse with an
appropriate rating (printed under the unit’s power
cable input). Using a fuse with an incorrect rating
can damage the unit and/or fuse.
3. Cooling Vent: Keep the area in front of this vent
clear from obstructions. The fan behind the vent
cools the loudspeaker’s amplifier, preventing
overheating.
4. Power Switch: Use this switch to power the
loudspeaker on/off. Make sure all volume knobs
are set to “zero” before powering it on.
5. Power LED: This light illuminates when the
loudspeaker is powered on.
6. Input: Use a standard 1/4” (6.35 mm) TRS or XLR
cable (not included) to connect your sound source
to this input. Use the input volume knob to adjust
the level of each one.
7. Input Volume: Turn this knob to adjust the volume
of each input.
8. Mix Out: Use a standard XLR cable (not included)
to connect this output to the input of another
loudspeaker. The signal sent from this output is a
summed mono signal of the two inputs.
9. Signal Limit LED: This light illuminates when a
high audio signal level activates the internal
protection circuit. The protection circuit
dynamically reduces the signal level to avoid
audible distortion and to protect the woofer and
high-frequency driver from over-excursion or
mechanical damage. If this light is lit constantly, or
the sound is distorted, reduce the signal level of
your sound source, or lower the volume with the
Volume knob.
10.
Contour: Engage (depress) this switch to
emphasize low and high frequencies by +3 dB.
Disengage (raise) the switch for a “flatter”
response for live performance or for maximum
output.
11. Ground Switch: Engage (depress) this switch to
reduce hum or noise.
