This tiny amplifier packs a serious full-range punch delivering a staggering 100 watts to each of its four channels into 2 ohms. The breakthrough that makes this much power possible in such a small chassis is the NexD ultra-high-speed switching design which allows for full bandwidth Class D operation with extremely low distortion and outstanding efficiency. Use the XD400/4v2 in combination with XD600/1 monoblock to build a 1000 W amplification system to power four satellites and a subwoofer and fit the whole thing under a seat. Or use the XD400/4v2 by itself to power two satellites plus a subwoofer. With XD’s the possibilities are endless. The XD400/4v2 includes a 12 dB/octave filter for each channel bank which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-500 Hz. The XD400/4v2 also features the v2 Spec feature set which consists of automatic turn-on capability and a dual-range differential-balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control the amplifier’s level can be directly controlled from the driver’s seat. This amplifier features a black powder-coat finish and a gasketed brushed aluminum cover for the controls.
