Description

TOA DA500FH is a 4-Channel Digital Power Amplifier designed for 100 V line high-impedance distribution and features lightweight, compact, high power output, and high efficiency.

TOA DA500FH delivers 500 W x 4 channels (20 ohm output) using a switching power supply.

Each channel is equipped with an independent power section. It can be electrically isolated from the high-impedance speaker system by attaching the MT-251H Output Transformer (optional).

Its Control/Monitor terminals permit power ON/OFF control of the individual channels and status monitoring for the power ON/OFF on each channel, protection on each channel, and fan operation.

Prepare the control panel or status monitor display panel separately. It can be mounted in an EIA Standard equipment rack (2 unit size).

Extremely high amplification efficiency of 80-90%, resulting in reduction in power consumption by more than 60% compared with Class-AB amplifiers.

The DA-250 Series is 1-unit size and the DA-500 Series is 2-unit size. 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.

Stands up to extended hours of operation. The DA amplifier has undergone a large number of rigorous tests to prove its durability. In addition, TOA has been conducting a “non-stop driving test” of the DA Series.

The DA amplifier has a comprehensive protection circuitry for protection against excessive current flow due to overload, short circuit, unusual DC voltage output, and heat sink temperature rise.

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 Channels 2-4 (Channel 2 in case of DA-250D/DA-250DH). It is also possible to use one of the channels as a spare amplifier.
