Gain Switch; Phantom Power Switch; Invert Switch; Low Cut Control - Art PRO CHANNEL II Service Manual

GAIN Switch

This switch increases the tube gain by 20dB to support low output mics and instruments. It should
only be used when the GAIN control cannot provide enough gain.

Phantom Power Switch

The switch safely applies +48Volt phantom power to the XLR input. Use phantom power only when
the microphone that you are using requires it. Doing so will extend the life of the Pro Channel II as
well as reducing the possibility of shock hazard.

Invert Switch

This switch selects the output phase of the Pro Channel II. There is a 180-degree phase shift
through the Pro Channel II preamp section when lit.

Low Cut Control

This control allows adjustment of a 6dB/Oct high pass filter from 10Hz to 250 Hz. The filter is
designed to remove rumble, pops, and wind noise, yet still sound natural.

Preamp Output Control

This control adjusts the output of the Preamp section allowing up to 10dB of gain or allowing you to
mute the output when fully CCW.
