Product Description
This tiny amplifier packs a serious full-range punch, delivering a staggering 100 watts to each of its four
channels into 2 ohms (14.4V, 1% THD). The breakthrough that makes this much power possible in such a small
chassis is our NexDTM ultra-high-speed switching design, which allows for full bandwidth Class D operation with
extremely low distortion and outstanding efficiency. Use the XD400/4 in combination with our 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 XD400/4 by itself to power two satellites, plus a subwoofer. With XD's, the
possibilities are endless. The XD400/4 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. With the addition of an HD-RLC remote level control (sold separately), the amplifier's Ch. 1 & 2 level
or overall 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. Amazingly small in size, but huge in audio
performance, the JL Audio XD amplifiers are the perfect solution for space-conscious installations or for anyone
seeking affordable excellence in a mobile amplifier. As with their more expensive HD siblings, XD's also deploy
our Advanced Thermal Rollback System to completely eliminate annoying thermal shut-down events. Beneath
every XD's removable control cover, you will find studio-grade signal processing with fully variable crossover
filters. Also included are our noise-killing, highly flexible differential-balanced inputs with remote level control
capabilities via the HD-RLC remote level control (optional). Read more
