ESX QM500.4 – Ultra-Compact 4-Channel Class D Amplifier
Full description
The ESX QM500.4 is a 4-channel Class D amplifier that combines performance, compactness and energy efficiency . With its small dimensions ( 190 x 35 x 102 mm ), it fits easily into any vehicle , even when installation space is limited. It is inspired by the QUANTUM QL range, but in an even more compact and easy-to-integrate format.
Its power of 4 x 125W RMS under 2Ω (or 2 x 250W RMS in 4Ω bridged mode ) allows you to efficiently drive speakers or a subwoofer. Its high energy efficiency (up to 83%) guarantees clear sound reproduction while limiting power consumption and heat dissipation.
The ESX QM500.4 is equipped with comprehensive active filters , including an adjustable HPF (10-5000 Hz) , an adjustable LPF (50-5000 Hz) , and a Bandpass mode for optimal sound customization. It also incorporates high-level inputs with EPS® (Error Protection System) , automatic power-on , and Start/Stop compatibility , making it easy to integrate into a stock system .
For added flexibility, a compact bass control remote is included, allowing bass level adjustment directly from the driver's seat.
