Description
The A4432 is a versatile 8 input mixer with 5 channels, designed in collaboration with professional sound contractors. It brings together multiple audio sources in a compact unit, featuring the best aspects of our popular mixer and signal processing line. Inputs 1-4 can be configured for mic or line use, while input 5 provides 4 selectable line level RCAs and can be controlled remotely with the selection wallplate (A4433). Additional flexibility is available with the use of a local input plate (A4931), which can also mute input 5 when in use.
Tone Generator Operation.
The device includes a micro SD card slot for playing tones, chimes, and pre-recorded messages. The rear panel provides individual control levels for alert/evac, chime, and voice over options. These can be triggered by closing contacts from Fire Indicator Boards (FIB) or other remote sources, such as switches.
