ESX SXE2800.1D

The ESX SXE2800.1D from the SIGNUM SXE series is a powerful 1-channel Class D mono amplifier designed specifically for driving high-performance subwoofers. With an output power of up to 1,400 watts RMS into 1 ohm, it offers ample power reserves for powerful and controlled bass reproduction.

The high-quality amplifier circuitry, featuring NE5532 operational amplifiers in the input stage, enables precise signal processing with low distortion. The efficient MOSFET PWM power supply, with an efficiency of up to 84%, ensures reliable power delivery.

Thanks to its high-level inputs with the EPS Error Protection System and automatic power-on function, the amplifier is also suitable for integration into factory-installed sound systems. Extensive adjustment options—such as a low-pass filter, subsonic filter, bass boost, and continuously variable phase control—allow for customization to match the subwoofer being used.

The master/slave function allows two identical amplifiers to be connected to each other. A compact, wired bass-level remote control makes it easy to adjust the bass level.
