Digital SR Amplifier

Overview

The DSA100D is a compact half rack digital power amplifier. This two channel

amplifier uses Class D circuitry and switch mode power supply delivering

High power output with great efficiency. Its high efficiency design ensures low

power consumption with very low heat dissipation. Features include an input

sensitivity adjustment, a high pass filter and remote contact closure power on.

The amplifier outputs can be bridged offering twice the output on one speaker

line. Euro Block type input and output terminals simplifies quick and easy of

installation. Using a external Output Transformer Unit (OPT-100D), DSA-100D

can be used in applications require a high impedance amplifier.

Compact Half Rack Digital Amplifier

With its compact half rack form factor design the amplifier delivers
high efficiency with low power consumption and very low heat
dissipation

HPF(High Pass filter)

HPF allows the amplifier to be used according to the kinds and
features of speakers.

ENERGY STAR CERTIFICATION

ENERGY STAR CERTIFICATE that EPA and DOE recognize is
achieved, and it is eco-friendly product which has high energy
efficiency and low standby power(less than 1W).

Bridge Mode

The amplifier outputs can be bridged offering twice the output on
one speaker line.

Remote Power ON/OFF

The remote power on allows the amplifier to be turned on or off
from other device via dry contact closure.

Euro Block

Euro Block type input and output terminals give an advantage of
easy installation without a certain connector.

Input Sensitivity Adjustment

The input sensitivity adjustment allows the amplifier to be used
with a variety of input sources.

External Output Transformer Unit

Using a external Output Transformer Unit (OPT-100D), DSA-100D
can be used in applications require a high impedance amplifier
which has 70V/100V output.

VCA(Voltage Control Amplifier)

(DSA-100DV)

VCA is a circuit that sound volume is changed according to
control voltage. If sound volume is needed to be changed in an
external area, it is possible to control without noise even though
connected line of variable resistance is long if VCA control is
used.
