DA-250FH

Digital Power Amplifiers

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 ƒ 4 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).

  • 4 x 250 W power output
  • 100 V speaker output
  • Low power consumption and light weight
  • Each channel with independent power supply
  • Control covers eliminate tampering
  • Low-noise constant speed fans
  • Stacking possible
  • Protection circuitry
  • Pulse width modulation with controlled power supply
