Description

Details

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. The 40881 supplies 50 Watts of power, 25 Watts per channel, and is built to an industry standard 25/70 Volt design. It supports many advanced features which make it a perfect fit for most applications.

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. The 40881 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. After five minutes without a signal, the amplifier will enter standby mode providing energy savings. It will wake from standby mode instantly when a signal is received.

The 40881 accepts 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. It is designed to accept either RS232 control or control signals from an industry standard volume control.
