Digital Power Amplifier, 2x 250 W @ 4 Ohm (2x 170 W @ 8 Ohm), 1x 500 W Bridged @ 8 Ohm (1U)

The DA-250D from Toa Electronics is a high-quality 1RU digital amplifier designed for installed applications. It offers two channels of input and output, with removable terminal block inputs and a screw terminal strip for outputs. If desired, the first input channel signal can be routed to both outputs, perfect for multi-zone paging.

The front of the unit provides large control knobs for input level control, as well as LEDs to show input, output, power, peak, and protect status. The built-in protection circuitry protects against damages from short circuits, overloads, and overheating. Class-D circuitry provides excellent audio quality and allows the DA-250D to operate at 85 percent efficiency, so it consumes almost 1/3 less power than analog amplifiers.
