ESX SX 800.4

With the new SIGNUM SX power amplifiers, ESX is opening a whole new chapter: For the first time, the series features heavy, precision-fit heat sinks made of die-cast aluminum – a feature previously unheard of in this price range. The advantages are obvious: The solid construction combined with modern Class D technology allows the cabinets to remain astonishingly compact and set new standards with their high efficiency and performance. This makes the SIGNUM SX series the ideal solution for anyone who demands exceptional quality in sound and workmanship.   The 4-channel SX800.4 is the all-rounder in the SIGNUM SX series. With a clean 4 x 200 watts RMS at 2 ohms, this amplifier delivers more than astonishing power for its size, along with top-notch sound, making it highly recommended for powerful front and rear speaker systems. Thanks to its generously sized high-pass and low-pass filter sections, adjustable from 50-5000 Hz per channel pair, it can also drive high-quality 2-way systems in fully active mode. If a 3-channel configuration with a subwoofer is required, this is also possible thanks to the mono bridged mode. With 400 watts RMS at 4 ohms, it optimally drives mid-sized subwoofers. The included bass level remote control perfectly complements the 3-channel setup.
