The DA-250DH is a 2-channel digital power amplifier designed for 70V line high-impedance distribution and features lightweight, compact, high power output and high efficiency. It delivers 250W x 2 channels (19.6 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). It can be mounted in an EIA Standard equipment rack (1 unit size).
  • High efficiency
  • Amplifier with world-class lightweight design
  • Compact design
  • Highly durable
  • High reliability
  • Independent power supply
  • 500W (1kHz, 4 ohm) total output all channel driven
  • 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. In addition, TOA has been conducting a “non-stop driving test” of the DA series.
  • Includes 1 power cord (2 m (6.56 ft)), 2 removable terminal plug (3-pin) and 2 tamper-proof cap
  • MT-251H matching transformer optional
