Front Panel (cont.)
15. Aux Level
Use this to control the level of an audio device plugged into the Aux input. Note
that the Aux channel is independent of the Mute switch, so you can play pre-
recorded music on your breaks.
16. Master Volume
Set the overall level of the Loudbox Artist with the Master Volume. In general
put the Master Volume as high as possible (2 o’clock to 5 o’clock) to achieve the
cleanest sound.
17. Power
Lights up when the amplifi er power is on.
18. Headphone Jack
When you plug in stereo headphones here, the speakers shut off. This output
monitors Channels 1 & 2 and the Aux input, so you can play along with
pre-recorded music through the headphones.
19. Channel Mute
The Channel Mute switch shuts off the signals from Channels 1 and 2 to the
speakers and all XLR outputs. The Channel Mute does not affect the Aux Inputs
or the effects sends. When mute is active, its button LED will be lit.
20. Tweeter Level
Turn this control to attenuate the tweeter’s output level to where it sounds best
to you.
21. Phantom Power
Provides 24V to the XLR input on each input channel to power a condenser
microphone. When phantom power is active, its button LED will be lit.
Most condenser and dynamic microphones, as well as some
preamps, can be used safely with phantom power.
However, phantom power can damage some audio devices including some
unbalanced mics, preamps or stompboxes that have been modifi ed for
balanced XLR use. Whenever there is doubt, contact the manufacturer to
confi rm compatibility.
