Switch between up to four audio feeds and mix in an independent mic or line-level input to the selected audio channel with the 4 x 1 Audio Switcher with Mic/Line Voice Mixer & Mono Amplifier from FSR. Featuring four switched program audio inputs and a mic/line-level input, this switcher enables you to add the feed from a voice-lift system or microphone to your selected active program audio. Additionally, an integrated 25W mono audio amplifier enables you to drive either a 4- to 8-ohm speaker or a 70V line output.

The switcher offers balanced/unbalanced input and output capability and is equipped with DIP switches that allow you to set the voice input level to mic or line, adjust microphone sensitivity, set phantom power, and select mono or stereo operation. There are two sets of control buttons for adjusting the volume or muting the program audio and voice inputs. In addition to the front-panel push buttons, the switcher can also be controlled via an external dry contact closure or RS-232 serial commands.
