The TOA DA-250FH power amplifier utilizes advanced digital technology to provide multi-channel high power outputs. Featuring high efficiency amplifier topology, the high impedance version DA-250FH is ideal for various installed sound applications.

Description

The DA-250FH is a 4-channel digital power amplifier designed for 70V line high-impedance distribution and features lightweight, compact, high power output, and high efficiency. It delivers 250 W x 4 channels (19.6 Ω 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). It can be mounted in an EIA Standard equipment rack (1 unit size).

Features
  • 4x 250W (70V)
  • 2x 500W bridged mode (140V)
