Amply 4 kênh TOA DA-250FH
-The DA-250FH is a 4-Channel Digital Power Amplifier designed for 70 V 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).
