ZXM500.4 – 4 channel MINI Amplifier

Small in size big in power

The ZXM500.4 is an impressive Class-D 4-channel Mini Amplifier. The ZXM amplifiers are made to be as small as possible without compromising sound quality, power and functions. The ZXM500.4 is a 4-channel amplifier with a total power of 500W RMS. This equals 4x80W RMS in 4Ohm but the amplifier is stable into 2Ohm and then delivers 4x125W RMS. The 4 channels can also be bridged into 2x250W RMS in 4Ohm. The amplifier comes with adjustable HP/ LP filters and also a switch to use 2ch input or 4ch input low or high level.

A high level of engineering has gone into making these amps with low EMI emissions to not interfere with the advanced electronics or FM signal.
