Setup

Volume Control

The TS3 Series loudspeaker accepts 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 TS3 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 TS3 loudspeaker.
