Setup
Volume Control (TX208 & TX210 only)
The TX208 and TX210 loudspeakers accept both line-level and mic-level audio sources.
Before connecting your audio source, turn the Volume knob to the minimum position (fully
counter-clockwise).
Line-Level Audio Source
When using an audio source such as a mixer, CD/MP3 player or audio preamp, follow the
outer/Line level band indicator.
If the Signal Limit LED is on, do not advance the Volume knob any further. Doing so may
damage your TX2 loudspeaker.
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 (as explained above).
Mic-Level Audio Source
Important: If you are using an instrument with active preamp, treat the instrument as a
line-level audio source (as explained above).
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.
As you turn up the Volume knob, please observe the Signal Limit indicator. If the Signal
Limit LED is on, do not advance the Volume knob any further. Doing so may damage
your TX2 loudspeaker.
