The new SIGNUM SXE series is visually inspired by the successful HORIZON HXE series. It features massive connection terminals and the noble aluminum end panels which takes it a class higher. The new amplifiers are also the first choice in terms of sound: The high-quality NE5532 operation amplifiers in the input section ensure the finest resolutions over the entire frequency range and guarantee lowest distortion values. The amps were also upgraded with the high-level inputs with auto turn-on; they are equipped with the “Error Protection System” (EPS), so when connected to OEM factory radios no functions are impaired or error messages are written to the vehicle memory. All models are equipped with bandpass filters and the 1 ohm stable, high-performance Class D mono blocks offer additionally a phase controller and the master/ slave option for linking two identical amps including a very small, easy-to-install cable remote control for the bass level.
