TheDA-250DH is a 2-Channel Digital Power Amplifier designed for 70 V linehigh-impedance distribution and features lightweight, compact, high poweroutput, and high efficiency. It delivers 250 W × 2 channels (19.6 O output)using a switching power supply. Each channel is equipped with an independentpower section. It can be electrically isolated from the high-impedance speakersystem by attaching the MT-251H Output Transformer (optional). It can bemounted in an EIA Standard equipment rack (1 unit size).
