The TOA DA-250F is a 4-Channel Digital Power Amplifier featuring lightweight, compact, high power output, and high efficiency. It delivers 250 W × 4 channels (4 Ω output) using a switching power supply. Each channel is equipped with an independent power section. It can be mounted in an EIA Standard equipment rack (1 unit size).

 

The DA-250F power amplifier utilizes advanced digital technology to provide multi-channel high power outputs. Featuring high efficiency amplifier topology, the low impedance DA-250F is ideal for various installed sound applications. The lightweight construction and compact dimensions of the DA Series allows for easy placement in virtually any venue, as well as for use in stacked configurations as required. Each amplifier is equipped with low-noise constant speed fans for adequate cooling and designed for ultra-reliable long-term operation with multiple independent power supplies that ensure uninterrupted operation even if a channel fails. Redundant protection circuitry monitors amplifier status and protects the amplifier and system in case of problems.
