Atlas IED AA400PHD 6-Channel Input, 400W Amplifier Mixer

The 6-input 400 watt AA400PHD from Atlas is a multi-zone mixer amplifier designed for distributed business paging, background music (BGM), and applications where music on hold (MOH) plus paging is required. The AA400PHD can run 4 Ohm speakers or 25/70V lines, making it ideal for retrofitting as well as new installs.

Installers will appreciate the input selection which includes 4 balanced mic/line/telephone, and 2 unbalanced stereo line inputs that will accommodate paging microphones, CD players, and digital music receivers. The balanced mic/line/telephone inputs are accessed via euroblock connectors, featuring phantom power per mic for use with condenser microphones, while the stereo line ins are on RCA jacks. There's also a 3.5mm stereo jack available for mobile device plug-in.

The AA400PHD provides for remote volume control of the master or music channel by adding an optional wall plate connected to the VCA terminals. This feature is handy for music level adjustments from a central location and can also be assigned to the entire amplifier. VOX muting is also included allowing a signal on input one to mute one of the other channels such as the music during an announcement.

External gear like EQs or limiters can be hooked up via the preamp out / power amp in terminals providing greater flexibility and control. Atlas included their innovative Push Here Diagnostic (PHD) for 70V systems. All you need to do is push a button and the amplifier will confirm all tap settings are correct and that there are no speaker shorts.

Full-featured and hassle-free, make your next install an AA400PHD.
