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 pow

consumption b

y 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 r

igorous tests to prove its durability. In addition,TOA

has been conducting

“non-stop driving test” of the DA Series.

• High reliability

The DA amplifier has a comprehensive protection circuitry for protection against excessiv

current flo

w due to overload, short circuit, unusual DC voltage output, and pow

er amplifier

heat sink temper

ature 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 the

require only a small installation space

. Because the amplifiers do not generate m

uch

heat, 5 units can be stac

ked together in a rack.

• Independent power supply

Each of the channels has its own power supply. If the pow

er supply of Channel 1 should

fail, this w

on't affect the operation of Channels 2-4. It is also possible to use one of the

channels as a spare amplifier.
