Mono IFB Plus Stereo Audio Input.
RemoteAmp Two provides a listen only connection for mono IFB or full bandwidth stereo music listening. Separate volume controls for the XLR and 3.5 mm line input jacks allow a simple mix of mono and stereo sources. The XLR line level input accepts either a balanced mono signal, or a party line intercom feed (listen-only). The ½ watt, ¼” stereo headphone jack will cut through any crowd noise. Connect an IFB earpiece to the 3.5 mm earpiece jack for mono operation.
