This range of four channel power amplifier is Class-D series, which built four separate amplifiers into are single chassis. The output power of this series amplifiers are 120W, 240W, 350W and
500W by four channels. The amplifiers are designed to be both tabletop and rack mount in 1U height. A shinning feature of this amplifier is that power electricity saving technology has been
adopted . From one hand, switch power supply, the machine efficiency is as high as 85%. From another hand, this amplifier is also preferable for much lower heat generation of less than 55
even at severe working conditions, thus this benefits are not only good for green environment but also good for extension of life span. Four channel separate balanced line inputs by phoenix
connectors . Four channel RJ45 ports for remote power control, volume control and status monitor. Remote power on/off could be done through the RJ45 port. Four channel separate speaker
outputs of 100V line without transformer. Four Channel separate volume control. Four channel separate status indicatorsinclude signal, peak and protection. AC 230V working voltage. Four
channel separate DC 24V input for higher reliability, which is also designed for wide range protection within 20V to 25.6V, so as to protect battery during power shortage and protect circuit from
high voltage damage. Four channel separate cooling system to ensure the system internal temp kept under 55 . Extensive protection includes high temp, overload and short-circuit.
