The DMPA12 is a powerful digital audio processor and multi-channel power amplifier combined into a single rack space component designed to work with DM Series processors. The design represents a milestone in DSP technology in its basic architecture and in its processing speed and efficiency. The primary applications are sound reinforcement and teleconferencing systems in boardrooms, courtrooms, lecture halls, distance learning applications, hotels and other systems with multiple microphones and loudspeakers. The design is ideally suited to mix-minus sound reinforcement designs.
