Operations
Signal input gain control
The PR-Series mixer-amplifiers can accept balanced mic or line input signals, thanks to the gain selection switches
(figure 3.1).
Phantom power
The PR-Series mixer-amplifiers can supply 48V DC phantom power to use condenser microphones on any of the
mic channels. To use phantom power, please set the switch to the PH position (figure 3.1).

VOX Priority / Ducking
The PR-Series mixer-amplifiers offers a MIC priority / Vox feature for input 1-4. When set to on, this slide
switch configures mic channels 1-4 to mute the other input channels when a signal is present on the connected
microphones. The level at which an input will mute the other ones can be adjusted by the LEVEL volume.

Priority Control
The PR-Series mixer-amplifiers have a three (3) layer priority mute function. When a higher priority source is ac�vated,
other input signals are muted except the sources on the same priority level.

User message recording and playback
The PR-Series mixer-amplifiers have an internal memory for recording and playback of a simple message.
You can record and playback a message of approximately 60 seconds. This message is recorded and played via contact
closure on the rear panel. The message can be sent to a specific zone but selecting the zone prior to activating the
contact closure.
