Description
Speaker bi-amplification via Digital Signal Processing lies at the foundation of PRO design philosophy and the DPA-1002 combines these technologies into a single light weight rack-mount chassis.
Delivering 1000 watts per channel into a 4-ohm load, the DPA-1002 is a powerful solution for theater system amplification. Designed to bi-amplify PRO’s medium and large format screen channel loudspeakers and subwoofers, each DPA-1002 comes pre-programmed from the factory for the speaker model with which it will be paired. Each amplifier houses on-board DSP processing for all crossover functions, time alignment, and high-resolution frequency response shaping. But unlike the DPA-502, one channel of the DPA-1002 is optimized for driving the LF drivers within the system. As such, it may not be used as a traditional power amplifier to drive a full range speaker on each channel.
Beyond its high output power and DSP processing prowess, the DPA-1002 offers intelligent feedback of system status to simplify installation and troubleshooting of the system. LED indicators for power, signal present, clipping, and protect modes, are provided on the rear of the chassis, where they are easily accessible during system set-up and tuning, but will not interfere with theater room aesthetics during operation. In addition to system diagnostics, the DPA-1002 offers selectable DSP “voicings” allowing the installer / system designer to compensate for loudspeaker placement in either 2-pi (in-wall) or 4-pi (free field) environments. Selectable via a simple push button located on the rear panel of the amplifier, a frequency contour optimized to the speaker’s position corrects for boundary interaction, resulting in an accurate system response even with the loudspeaker flushed into a wall.
Built upon proven Class-D technology from Bang & Olufsen, the DPA-1002 operates so efficiently that large heat sink fins or cooling fans are not required. As a result, the amplifiers are dead-quiet in the rack and can be safely mounted tightly together without concern of over-heating. Each DPA-1002 has its power switch located on the rear panel along with a 12 volt/contact-closure sensor for remote power-on control. The 12VDC trigger input draws very little current and the looping output jack makes controlling a whole rack of DPA amplifiers a breeze.
