1. AC Input: Use the included power cable to
connect this input to a power outlet. Make sure
the 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 or off. Make sure the Volume
knob is set to its minimum (counterclockwise)
position before turning it on.
4. Power LED: This LED lights up when the
loudspeaker is on.
5. Cooling Vent: Keep the area in front of this vent
clear from obstructions. The fan behind the vent
cools the amplifier, preventing overheating.
6. Volume: Turn this knob to adjust the loudspeaker's
volume.
7. Input: Use a standard XLR or 1/4" (6.35 mm) TRS
cable (not included) to connect your audio source
to this input. Make sure to set the Input Selector
to the correct position.
8. Input Selector: Set this switch to the Line position
when using a line-level audio source connected to
the Input. Set this switch to the Mic position when
using a microphone connected to the Input.
9. Mix Out: Use a standard XLR cable (not included)
to connect this output to the input of another
loudspeaker (i.e., another TX3 loudspeaker).
10. 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.
11. Contour: Engage
emphasize low and high frequencies by +3 dB.
Disengage (raise) the switch for a flatter response
for live performance or for maximum output.
12. Ground Switch: Engage (depress) this switch to
reduce hum or noise.
