General Information
Manufacturer	Toa Electronics
Manufacturer Part Number	A-812D
Product Name	Digital Mixer Amplifier, Black
Overview
This mixer amplifier provides maximum flexibility with up to eight inputs and up to 120 W of power. Browser based control and monitoring from anywhere reduces your time troubleshooting and adjusting systems. Onboard DSP, a sleek new appearance, optional MOH output, two available 900 series module slots and TOA's legendary quality and reliability makes this a perfect fit for background and foreground music, paging, and noise masking applications. The amplifier offers a single speaker output that's switchable between 4 ohms and 70V operation. The integrated Power Factor Correction (PFC) circuit prevents damage from faulty power. The unit offers several functions, including volume control, priority, chime, and remote confirmation. In addition, it is equipped with a 2-channel input Bus of Audio and Duck, and the signal processing function. The A-812D includes a power cord, several block terminal plugs, a volume control cover, and rackmount hardware.
