LD Systems XS400 Power Amplifier
The XS400 is an extremely compact, dependable Class D power amplifier with an output of 200W per channel at 4 ohms 400W in 8-ohm bridged mode, and a wide transmission range of 20Hz – 20kHz. Our Class D power amplifier technology makes it possible to pack high performance into a minimum of space without generating unnecessary loss energy. The XS400, at 1U and a weight of 3.4kg, is conceived for all professional applications in which ease of transport or space is important, whether mobile or in permanent installations.

The XS400 has all protection circuits against short-circuiting, DC, overheating, and overloading and has a soft-start delay. The amplifier features XLR, RCA and jack input connectors, with Speakon-compatible sockets and screw terminals as outputs. On the rear panel, it is possible to select the mode of operation and gain and activate the limiter and ground-lift function. LEDs on the front indicate power, signal, clipping, triggering of the protection circuit, and the mode of operation. The transparent sound of the XS400 stands out with high dynamics and impulse fidelity.
