ESX SXE1000.5

The ESX SIGNUM SXE1000.5 is a high-performance 5-channel power amplifier that combines high-quality sound reproduction with powerful bass performance. Thanks to its innovative hybrid technology, the amplifier combines four Class A/B channels for front and rear speakers with a high-performance Class D mono channel for the subwoofer.

The SIGNUM SXE series takes its visual cues from the proven HORIZON HXE series and impresses with solid connection terminals, high-quality aluminum end panels, and elegant craftsmanship. High-quality NE5532 operational amplifiers are used in the input stage, enabling detailed music reproduction with exceptionally low distortion.

With a total output of up to 1,000 watts RMS, the SXE1000.5 offers ample power reserves for demanding car audio systems. The built-in high-level inputs with automatic power-on function and EPS® (Error Protection System) also allow for integration into vehicles with factory-installed radio systems.

Individually adjustable crossovers, an adjustable subsonic filter, and the included bass level remote control allow for precise tuning to the connected speakers and subwoofer.
