The AA400PHD is a six input channel mixer amplifier designed for distributed business paging and background music (BGM) systems, medium to large sound masking systems, and in applications where music on hold (MOH) plus paging is required.

The AA400PHD provides 400-watts output power into 25V, 70.7V, or 4Ω speaker systems. Rear panel DIP switch allows for creation of Zone 2 output mix using any or all of inputs 1-4. Unit can also be set-up to mute Inputs 2 through 6 on signal from Input 1 for paging applications where other input sources need to be muted during a page. Inputs 1-4 are either Mic or Line input selectable and Phantom Power is an option when using them as a microphone input.
