description

TOA DA500FH is a four-channel digital energy Amplifier designed for one hundred V line excessive-impedance distribution and functions light-weight, compact, high strength output, and high efficiency.

TOA DA500FH delivers 500 W x four channels (20-ohm output) using a switching strength supply.

each channel is equipped with an independent strength section. it could be electrically remoted from the excessive-impedance speaker machine via attaching the MT-251H Output Transformer (elective).

Its control/display terminals permit energy ON/OFF manipulation of the individual channels and standing monitoring for the electricity ON/OFF on each channel, protection on every channel, and fan operation.

prepare the manage panel or popularity reveal show panel one by one. it can be mounted in an EIA trendy gadget rack (2 unit length).

extremely high amplification efficiency of eighty-ninety, resulting in a reduction in power intake by more than 60% compared with class-AB amplifiers.

The DA-250 collection is 1-unit length and the DA-500 collection is 2-unit length. They may be successfully mounted on a rack so that they require only a small setup area. because the amplifiers no longer generate much heat, 5 devices may be stacked together in a rack.

Stands as much as extended hours of operation. The DA amplifier has passed a massive range of rigorous assessments to prove its sturdiness. Furthermore, TOA has been carrying out a “non-prevent using take a look at” of the DA series.

The DA amplifier has comprehensive protection circuitry for safety against excessive modern-day float because of overload, a brief circuit, uncommon DC voltage output, and heat sink temperature upward thrust.

each of the channels has the power to deliver. If the energy supply of Channel 1 should fail, this gained’t affect the operation of Channels 2-4 (Channel 2 in case of DA-250D/DA-250DH). it is also viable to apply one of the channels as a spare amplifier.
