Pro Audio Technology DMA-1508 Amplifier/DSP Processor

PRO DMA-1508 Amplifier

Pro Audio Technology (PRO) today announced the 1500-watt DMA-1508 1-RU, eight-channel digital amplifier with dealer-programmable DSP features. The compact 8-channel design provides a comprehensive suite of system calibration tools that make even the most advanced commercial or residential audio systems quick and easy to deploy.

Flexible by design, the DMA-1508 ships configured as an 8-channel unit featuring 2 x 300 watts and 6 x 100 watts of high-efficiency Class-D amplification in a chassis weighing less than 10 pounds. Each 100-watt channel pair can be bridged independently to create an additional mono channel delivering 300-watts, meaning integrators can deploy the DMA-1508 in configurations of 3x300w / 4x100w, or 4×300 / 2x100w, or for a maximum total power of 1500 watts, a 5×300 watt version.

In all of its possible power configurations, each channel of the DMA-1508 is controlled by the same proprietary state-of-the-art DSP software used to program PRO’s larger PMA amps. Features include programming for each of PRO’s loudspeaker and subwoofer products, brand specific compensation filters to adjust for screen attenuation, and environmental compensation filters for speaker placement near boundaries. Advanced controls include eight bands of parametric equalization per channel and independent channel gain and delay to allow integrators to optimize system low-frequency performance.

The gain of the DMA-1508 is also perfectly matched to PRO’s PMA amps, making it possible to mix and match the amps in larger systems. Advanced internal signal routing and looping outputs also make the DMA-1508 easily scalable for large distributed audio systems.

“System configuration and calibration are often time-consuming jobs that tie up critical staff and erode margins,” said Paul Hales, founder of Pro Audio Technology. “Manufacturers often make this process harder than it should be. With the DMA-1508’s trouble-free signal routing, flexible power configurations, and intuitive diagnostic feedback, installers can quickly and easily set up even the most complex distributed audio and home theater systems.”
