The TOA DA-250F/FH, DA-250D/DH and DA-550F/500F-HL multi-channel
power amplifiers offer a wider choice of power ratings, advanced digital
Class D amplification circuitry, and a highly efficient AC mains to output power
ratio, for the complete technological superiority it takes to support long-term
installation applications. These energy-efficient, space-saving amplifiers are designed to combine
high levels of performance and efficiency, and are well-suited to ensure sound reinforcement reliability
in a wide range of venue types. The low-impedance models are ideal for multi-zone applications such
as presentation and press-conference rooms, restaurants and similar-sized locations. The high-
impedance units are well-suited to such locations as exhibition halls, sports facilities, multipurpose
halls and houses of worship.
