TOA POWER AMPLIFIER 4x250W/70V

The DA-250FH 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. It delivers 250 W x 4 channels (40 ohms 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-250H Output Transformer (optional). It can be mounted in an EIA Standard equipment rack (1 unit size).
