ESX HXE100.4

The ESX HXE100.4 from the HORIZON series is a powerful 4-channel Class A/B analog amplifier that combines robust technology, versatile settings, and high-quality craftsmanship. With an RMS output power of 4 x 60 watts into 4 ohms or 4 x 100 watts into 2 ohms, this power amplifier is ideal for driving front and rear speakers.

Thanks to the bridge configuration, which delivers up to 2 x 200 watts RMS at 4 ohms, even high-power speaker systems or subwoofers can be driven. The built-in high-pass and low-pass filters allow for individual adjustment of the frequency ranges. Additionally, a bandpass function and an adjustable bass boost are available.

The solid aluminum heat sink with acrylic inserts, the recessed diamond-cut logo, and the sturdy connection terminals highlight the high-quality construction. A MOSFET PWM power supply and a triple protection circuit ensure a reliable power supply and safe operation.
