ESX SXE2000.1D

The ESX SIGNUM SXE2000.1D is a high-performance digital mono amplifier from the SIGNUM SXE series, designed specifically for the powerful and precise drive of subwoofers. With up to 1,000 watts RMS at 1 ohm, this power amplifier offers ample power reserves for demanding car audio systems.

The SIGNUM SXE series is visually modeled after the proven HORIZON HXE series and impresses with its high-quality construction, featuring solid connection terminals, aluminum end panels, and a robust heat sink. High-quality NE5532 operational amplifiers in the input stage ensure clean signal processing and low distortion.

Thanks to the built-in high-level inputs with EPS (Error Protection System), the amplifier can also be integrated into vehicles equipped with factory-installed car radios. The system is designed to prevent error messages and malfunctions caused by the connection to the original radio. An automatic power-on function via the high-level inputs further simplifies installation.

For custom bass tuning, the SXE2000.1D features an adjustable low-pass filter, subsonic filter, bass boost, and phase control. The master/slave function allows two identical amplifiers to be connected to each other. A compact bass-level remote control is also included.
