Features
Rear Panel: TX308 & TX310
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.
6. Volume: Turn this knob to adjust the loudspeaker's
volume.
When using an audio source such as a mixer, CD/MP3
player or audio preamp, follow the outer/Line level band
indicator. In most circumstances, you will not need to
turn the volume beyond 0 dB. If your audio source has
unusually low output, you may turn the Volume knob
past 0 dB, but not past the Signal Limit indicator.
When using a microphone or instrument audio source,
follow the inner/Mic level band indicator. Because the
mic and instrument level is typically lower than a line
level, you can use the full rotation of the Volume knob.
Please see Setup > Volume Control
7. Input: Use a standard XLR cable (not included) to connect your audio source to this input. Make
sure to set the Volume knob to the correct position.
8. Mix Out: Use a standard XLR cable (not included) to connect this output to the input of another
loudspeaker (i.e., another TX3 loudspeaker).
9. Signal/Limit LED: This light illuminates green when audio signal is received and lights red 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.
