Amply 2 kênh TOA DA-250DH
The DA-250DH is a 2-channel digital power amplifier designed for 100V line high-impedance distribution and features lightweight, compact, high power output, and high efficiency.
It delivers 250 W x 2 channels (40 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).
