Toa Electronics DA-250DH - 2-Channel Digital Amplifier (2 x 250W @ 70V)
The DA-250DH from Toa Electronics is a high-quality 1RU digital amplifier designed for installed applications running at 70V. 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-250DH to operate at 85 percent efficiency, so it consumes almost 1/3 less power than analog amplifiers.
Sleek, 1RU unit fits into any standard audio rack
Two channels of I/O, perfect for multiple zones
Terminal block inputs and a screw terminal strip for outputs make it easy to connect equipment
The channel 1 input may be routed to all outputs, perfect for paging
Class-D circuitry for great audio quality and efficiency
Independent power supply for each channel
Simple interface with front-panel level control knobs
Protection circuitry for short circuits, overheating, and overloads
Status LEDs for power, input, output, peak, and protect
Removable dust filters for easy cleaning
