1. Cooling Vent: Keep the area in front of this vent
clear from obstructions. The fan behind the vent
cools the amplifier, preventing overheating. This
fan operates as needed to control the
amplifier's internal temperature. Due to minor
differences in electrical component tolerances,
it is normal for the fan speed and behavior to
vary from unit to unit. This variance does not
affect the unit's performance.
2. Power Input: Connect the included power
cable to this input and connect the other end
of the cable to a power source. Make sure the
Power Switch is set to off when plugging
and unplugging the cable.
3. 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.
4. Power Switch: Turns the loudspeaker on/off. Make sure the Input Volume knobs are set to
"zero" before turning it on.
5. Power LED: Illuminates when the loudspeaker is on.
6. Input 1: Use a standard XLR or 1/4" (6.35 mm) TRS cable (not included) to connect a sound
source to this input, and set the Line/Mic Selector appropriately.
7. Input 2 (XLR or 1/4" TRS): Use a standard XLR or 1/4" (6.35 mm) TRS cable (not included) to
connect a sound source to this input. The signal sent here will be mixed with the signal sent to
this input's RCA connectors.
8. Input 2 (RCA): Use a standard RCA cable to connect a sound source to this input. The signal
sent here will be mixed with the signal sent to this input's XLR+1/4" (6.35 mm) connector.
9. Line/Mic Selector: Set this switch to the Line position when using a line-level audio source
connected to Input 1. Set this switch to the Mic position when using a microphone connected to
Input 1.
10. Input Volume: Turn this knob to adjust the input volume of the channel.
11. Signal/Limit LED: This LED lights up green when an audio signal is sent to the loudspeaker—it
flashes at lower levels and lights solidly at higher levels. The LED lights up red when output
limit/protection is active—if the LED is lit red continuously, reduce the volume of your audio source.
12. Thru Output: Use a standard XLR cable (not included) to connect this output to the input of
another loudspeaker. The signal sent out of this output depends on the setting of the Input
1/Mix Selector.
13. Input 1/Mix Selector: Press this switch to determine the audio signal sent out of the Thru Output:
•
Input 1 (raised): The Input 1 signal is sent out of Thru Output, post-Input Volume.
•
Mix (depressed): The summed mono mix of both Inputs is sent out of the Thru Output,
post-Input Volume.
14. EQ Setting: Set this switch to determine the loudspeaker's equalization:
•
Flat: The levels of the frequencies of the output signal will be the same as those of the
input signal. We recommend this setting if you intend to make EQ adjustments on an
external mixer.
•
Boost: The low and high frequencies will be boosted slightly while mid-range frequencies
are reduced slightly. We recommend this setting for lower listening levels.
