DPA-4300M: Power Amplifier 4CH

Model: DPA-4300M 
Manufacturer: INTER-M - KOREA

•Rated Output Power : 300 W

•High efficiency and low heat generation design

•Using digital amp(OPT LESS)and SMPS

•Detachable and hot swappable module type for easy maintenance


Digital amplifier DPA-4300M is designed to organize the four channels of sound amplification systems in public address. Amplifier consists of a base unit and modules independent amplifiers DM-300 , placed in the compartments of the base unit.

Each module DM-300 has 2 line inputs: PGM and PRI. Adjust the volume to the inputs of the PGM and PRI produced independently. In normal operation, each channel reinforces the input signal from the PGM. When an emergency occurs, and contact closure PRI SELECT module DM-300 amplifies the input signal from PRI.

Setting the parameters of the amplifier modules are individually. To do this, on the front panel of each unit there are volume buttons, select the priority input source, start the self-test, turn on the power. Provided the "hot" replacement module DM-300 in the case of its failure.

In addition to the basic mode of operation, DPA-4300M can work in parallel and bridged modes. Bridged mode allows you to get two independent channels of amplification with 600 watts each.

Thanks to the integrated Ethernet-interface and specialized software DPA-4300M can communicate with the computer over the network. The software allows you to monitor the current state of DPA-4300M and modules DM-300 operating mode, temperature and fan speed. You also have the ability to remotely control the operation of each module DM-300: Power On, changing the volume of the signal, and so on. N.

DPA-4300M has an effective protection against excess voltage and temperature, as well as over-the exit.
