Product Description
The 25/70V 50W Audio Amplifier is the ideal solution for supporting a distributed audio system in a classroom, conference room or other environment that requires installation in a plenum space. This amplifier supplies 50 Watts of power, 25 Watts per channel, and is built to an industry standard 25/70 Volt design. This amplifier supports many advanced features which make it a perfect fit for most applications
Noise Reduction
Audio systems installed in commercial environments are susceptible to noise caused by an electrical ground loop. This will often manifest as a hum or buzz through the system. This amplifier features noise reduction technology on both the 3.5mm and RCA Stereo Audio inputs. This noise reduction eliminates the interference and allows the audio signal to pass through.
Standby Mode
After five minutes without a signal, the amplifier will enter standby mode providing energy savings. The amplifier will wake from standby mode automatically when a signal is received.
Accessory Power Output
The accessory power output provides 12 Volts DC and 500 mAmps. This makes the amplifier the perfect match for a controller such as the TruLink® A/V Controller
Multiple Inputs
This amplifier acccepts a 3.5mm and RCA Stereo Audio input as well as a 3.5mm Microphone input. The mixing function ensures that audio from all three inputs are mixed and sent to the speaker outputs.
Remote Control
This amplifier is designed to accept either RS232 control or control signals from an industry standard volume control.
Public Address (PA) Sensor
The PA sensor will automatically mute the audio inputs of the amplifier allowing the public address to be heard.

Will this amp duck to a page if tied in? It looks like it would but there is no mention of it.
Asked by: FlattopMike
It sounds like you are asking if the intercom or PA is tied in will it switchover during use, and the answer is yes.
