Description

With the new SIGNUM SX power amplifiers, ESX opens a new chapter: for the first time in the series, robust and perfectly fitting die-cast aluminum heatsinks are used – a feature never before seen in this price range. The advantages are clear: thanks to robust construction combined with modern Class D technology, the enclosures remain remarkably compact and set new standards in efficiency and performance.

The 4-channel amplifier SX800.4 is the versatile model in the SIGNUM SX series. With a power of 4 x 200 watts RMS at 2 ohms, it offers impressive power for its size, as well as exceptional sound quality, making it ideal for powerful front and rear speaker systems. Thanks to its high-capacity high-pass and low-pass filters, adjustable from 50 to 5,000 Hz per channel pair, it can also power high-end 2-way systems in active mode.

If a 3-channel configuration with a subwoofer is needed, this is also possible thanks to the bridged mono mode. With 400 watts RMS at 4 ohms, it optimally powers medium-sized subwoofers. The included bass level remote control perfectly complements the 3-channel setup.

⚠️ IMPORTANT - INSTALLATION: It is IMPERATIVE to connect this amplifier at the impedance recommended by the manufacturer and to use the recommended wiring size. For amplifiers over 2000W RMS, the vehicle's original battery is no longer sufficient. It is strongly advised to adapt the power supply (additional battery, reinforced alternator) to the amplifier's consumption to avoid any risk of damage and ensure optimal performance. WARNING: Any voltage drop below 12V can damage the product.
