ESX SXE1200.1D

The ESX SXE1200.1D from the SIGNUM SXE series is a high-performance digital monoblock amplifier that impresses with its premium build quality, state-of-the-art amplification technology, and extensive customization options. The elegant design, featuring a solid aluminum heat sink, high-quality aluminum end panels, and a recessed diamond-cut logo, underscores the series’ high standards of quality.

High-quality NE5532 operational amplifiers in the input stage ensure precise signal processing, enabling detailed sound reproduction and low distortion. Thanks to efficient Class D technology, the amplifier achieves an efficiency of up to 88% and delivers an output power of up to 600 watts RMS into 1 ohm.

The built-in high-level inputs with the Error Protection System (EPS®) allow connection to factory-installed car stereos without interfering with their diagnostic functions. An automatic power-on function simplifies integration into existing vehicle systems.

To customize the subwoofer's settings, you have access to an adjustable low-pass filter, a subsonic filter, a bass boost, and a continuously variable 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.
