4+4 Channel Public Address Mixer

Designed in conjunction with pro-sound contractors, the A 4432 is a stand alone 8 input mixer with 5 channels which provides a flexible way to bring multiple audio sources together. It combines many of the best features from our popular mixer and signal processing range into one compact unit. Inputs 1 to 4 can be configured for either mic or line use. Mic inputs are 5 pin euro block including PTT contacts. Line level is via RCA. Input 5 consists of 4 line level RCAs which are selectable from the front panel. With the addition of the selection wallplate, input 5 sources can be selected and adjusted remotely. A local input plate (A4931) can be connected to the selection wallplate (A4433) offering additional flexibility within the zone. Inputs from A4931 will automatically mute input 5 sources.
Tone Generator Operation.
Tones, chimes and pre-recorded messages are played from the micro SD card which plugs into the rear panel of the mixer. Individual level controls are provided for alert/evac, chime and voice over. All of these can be triggered by closing contacts such as switches, from Fire Indicator Boards (FIB) or any other remote contact source.
