CLASS-D PA AMPLIFIER
2U Size High Power Class-D PA AMP
AC&DC Dual Power Operation
Class D audio amplifier with ECO Digital degine
offers greater than 90% power efficiency and
lower heat dissipation over traditional low
efficiency and noize from analog amplifier.
Wide Range of Selection
1CH (S) : 1200W/900W/600W/300W (4Type)
2CH (D) : 600+600W/300+300W (2Type)
3CH (T) : 300+300+300W (1Type)
4CH (Q) : 300+300+300+300W (1Type)
SMPS provides high efficiency and low weight
SMPS - Switch mode power supply provides high
efficiency and low weigh. Among their advantages
is their reduced physical size and lower heat
dissipation. SMPS offer power efficiency and
reduced power consumption over traditional
amplifiers.
AC & DC dual power operation. Normal power
operation via AC 220V electrical power input.
Amplifier will switch automatically to DC24V
battery backup supply input when AC power is
interrupted.
HPF Function
A 3 positions of HIGH PASS FILTER by
OFF/ 200Hz/400Hz, helps to improve speech
intelligibility.
Priority Program Override
Each amplifier module has 2 audio inputs.
The Primary program input, PGM and Priority
input, PRI. The primary regular broadcast program
input, PGM is interrupted and over ridden by the
Priority input, PRI, when a contact closure is
received on the PRI select terminal. This is Ideal for
Emergency message broadcasting applications.
Power On/Off Control with control
The user can control the Power On/OFF at a long
distance by using a control input.

input
It is easy to monitoring a status of amplifier with
LED display (RUN, -30dB, -10dB, CliP, Priority,
fault, AC, DC).
