T-4D120R - Global Sources
With RS232 Interface 4-Channel Class-D Power Amplifier
T-4D120R
Descriptions
The amplifier adopts high class D amplifier circuit, and it is built in high-efficient power switch
which enhances the efficiency up to 85%. The product uses reasonable dissipation layout,
which makes the amplifier can keep less than 55 even at severe working conditions,
thus largely expanding its life span.
The amplifier is designed with rack mount in 1.5 U height and 19 inches. The output power
of this series amplifiers are 120W, 240W and 350W and 500W. The rear panel provides with
4 channels 100V output terminal wiring speaker, and a RS232 connector for remote volume
control, remote product condition reading and remote standby control. Extensive protection
includes high temp, overload and short-circuit.

Features
* Built-in powered band pass signal filter, Effectively filter out useless audio signal.
* 4 channel balanced line inputs, 4-channel 4 120W/240W/350W/500W power output.
* 4 channel separate volume control.
* 4 channel separate status indicators include signal, peak, protection and Led power supply.
* With power amplifier output normal condition monitoring, power amplifier standby control
and power amplifier standby cascade port.
* With RS232 interface for remote control control switch machine and remote monitoring
power amplifier working condition. Capable to achieve 4 channels power amplifier volume
control adjustment, fault output feedback and trigger amplifier function etc.
* Power amplifier matches with DC 24V power supply terminal and has the voltage
protection within 21.6~26.5Vdc, which avoids long-term supply for battery failure or
damage of high voltage equipment.
* Speaker Output: 100V constant voltage.
* With the electric isolation of the equipments, and signal input and power amplifier output
is also isolated in electric, matching with 3C, UL, IEC60065 certificates.
* Extensive high temp, overload and short-circuit protection.
