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. Power Switch: Use this switch to power the
loudspeaker on/off. Make sure all volume
knobs are set to "zero" before powering it on.
4. Power LED: This light illuminates when the
loudspeaker is powered on.
5. Input: Use a standard 1/4" (6.35 mm) TRS or
XLR cable (not included) to connect your
sound source to each input. Use the input
volume knob to adjust the level of each one.
6. Input Volume: Turn this knob to adjust the
volume of each input.
7. 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.
8. 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.
9. 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.
10. Ground Switch: Engage (depress) this
switch to reduce hum or noise.
