Product Overview
The A812D mixer-amplifier from TOA provides up to 120 watts of power across eight inputs to drive background and foreground music, paging, and noise masking applications. It can be run at 4 Ohms or drive a 70V system.
Control and monitoring are possible from anywhere, thanks to the A812D's web-based interface. View and update volume levels or verify amplifier status from your office location. Then with a quick check of the downloadable log files, you can verify the need to dispatch a technician. Saving time saves money and your peace of mind is worth even more.
Onboard DSP, a sleek new appearance, MOH (music on hold) output, two available 900 series module slots, plus TOA's legendary quality and reliability make this an ideal choice for new and existing systems. Mic inputs 1-4 have phantom power available and 5-6 feature priority audio ducking with depth control plus a stereo RCA record out!
