ESX QM400.4 mini digital amplifier 4-channel Class D with 480 Watt RMS output power

The QM amplifiers offer cutting-edge technology in a very small space and are all solidly built. The three amplifiers of the QM series are based on the slightly larger models of the ESX QL series, maintaining more compact dimensions, making them much easier to install. Thanks to high-level inputs including EPS and the automatic turn-on function, they are also perfectly suited for integration into factory audio systems. Each model is also equipped with a compact remote control for bass level.

Beyond their power, they are also well equipped: EPS technology "Error Protection system" (protects against the impedance problem that can arise when modifying the audio system of a recent vehicle), high-level input with automatic turn-on.

Main features of the ESX QM400.4 amplifier
