DA-550F/500F-HL
Multi-Channel Digital Power Amplifiers
DESCRIPTION
FEATURES
The TOA DA-550F and DA-500F-HL multi-channel power amplifiers offer a wider choice of power ratings, advanced 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
DA-550F is ideal for multi-zone applications such as presentation and press-conference rooms, restaurants and similar-sized
locations. The DA-500F-HL is well-suited to such locations as exhibition halls, sports facilities, multipurpose halls and houses of
worship.

DA-500F-HL
•High efficiency
Extremely high amplification efficiency of 80-90%, resulting in reduction in power
consumption by more than 60% compared with Class-AB amplifiers.
•Highly durable
Stands up to extended hours of operation. The DA amplifier has undergone a large
number of rigorous tests to prove its durability. In addition,TOA has been conducting
a “non-stop driving test” of the DA Series.
•High reliability
The DA amplifier has a comprehensive protection circuitry for protection against excessive
current flow due to overload, short circuit, unusual DC voltage output, and power amplifier
heat sink temperature rise ( over 100°C), power supply temperature rise (over 80 C).°
•Amplifier with world-class lightweight design*
Installation has become much easier thanks to the lightweight design.
*TOA comparative data (weight/watt)
•Compact design
The DA-500 Series is 2-unit size, and they can be efficiently mounted on a rack, so they
require only a small installation space. Because the amplifiers do not generate much
heat, 5 units can be stacked together in a rack.
•Independent power supply
Each of the channels has its own power supply. If the power supply of Channel 1 should
fail, this won't affect the operation of Channels 2-4. It is also possible to use one of the
channels as a spare amplifier.
