DA-250DH

Digital Power Amplifiers

The DA-250DH is a 2-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 ƒ 2 channels (40 › 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).

  • 2x 250 W rated output
  • 100 V speaker outputs
  • Light weight and compact
  • Class D design 85 % efficient
  • For 19" cabinet rack mounting with 1 U height
  • Independent power supply for each channel
  • Forced-air cooling system
  • Low heat dissipation
  • Comprehensive protection circuitry
  • Removable dust filters for easy cleaning
