Connections
Inputs:
• AUX
A stereo combining RCA pair are provided for connection of an external
line level audio device. The AUX input works in conjunction with the
MUSIC SELECT switch and the MUSIC control on the unitʼs front panel.
• LINE
A stereo combining RCA pair are provided for connection of an external
line level audio device. The line input works in conjunction with the LINE
control on the unitʼs front panel.
Microphone Input:
• MIC
A standard XLR type balanced microphone connector is provided for the
connection of a paging microphone. The microphone can be either a
low impedance Dynamic or Electret Condenser type. The connection
polarities for the microphone input are printed on the rear panel near
the connector.
• PHANTOM
The Phantom push button allows phantom power to be supplied to the
microphone if it is needed. Only Electret Condenser microphones need
this function. It should be set to OFF for dynamic microphones.
• VOX
The VOX switch allows the microphone input to override the other audio
inputs when it is in use. By setting the switch to on, any audio activity
detected at the microphone input will mute the audio from the other
inputs until the microphone is no longer in use. With the VOX set to off,
the Microphone will not mute other inputs but instead mix into the audio
program with the other input sources.
Microphone inputs are very sensitive and can pick up the slightest audio
from the microphone. This can cause false signal triggering VOX muting.
Because of this, it is recommended to use a microphone that has an
ON/OFF switch that quiets the microphoneʼs output when it is off.
Push-to-talk desktop or gooseneck microphones work very well for this
purpose.
• AC Power
Plug the line cord into a standard 15A, 120VAC outlet after making all
the necessary connections. A push to reset circuit breaker provides
overload protection. Reset this breaker should the unit ever fail to turn on.
