Manufacturer Description

Digital multi-channel amplifier DA-250FH 4x 250W (70V) 2x 500W bridged (140V The DA Series multi-channel digital power amplifiers are ideal for multi-zone distributed speaker systems and professional sound applications. Engineered with Class D technology, the new DA Series amplifiers operate at 85 percent efficiency and consume almost one-third less power than conventional analog amplifiers. The compact and lightweight single or dual rack-space design and ultra-low heat dissipation allow designers to rack-mount up to five units without open space between units. The DA Series is comprised of high and low impedance four-channel models each equipped with an independent power supply for each channel to assure continuous operation and unmatched reliability and performance. Other features include recessed stepped attenuators for precise gain calibration, removable dust filters for easy maintenance, and optional isolation transformer. Competitively priced, the new DA Series multi-channel power amplifiers are backed by TOA's five-year warranty.

Product Features

Extremely high amplification efficiency of 80-90%, resulting in reduction in power consumption by more than 60% compared with Class-AB amplifiers. Stands up to extended hours of operation. The DA amplifier has undergone a large number of rigorous tests to prove its durability. The DA amplifier has a comprehensive protection circuitry for protection against excessive current flow due to overload, short circuit, unusual DC voltage output, and power amplifier heat sink temperature rise (over 110°C/167°F), temperature rise inside the unit (over 80°C/176°F). The DA-250 Series is 1-unit size, and they can be efficiently mounted on a rack, so they require only a small installation space. Because the amplifiers do not generate much heat, 5 units can be stacked together in a rack. Each of the channels has its own power supply. If the power supply of Channel 1 should fail, this won't affect the operation of Channel 2 - 4. It is also possible to use the either channel as a spare amplifier.
