JL AUDIO JX400/4D
4-Channel Class D Full-Range Amplifier, 100 W x 4 @ 2 Ω / 70 W x 4 @ 4 Ω - 14.4V
The JX400/4D employs a highly-efficient Class D design with a robust MOSFET power supply to deliver a strong 100 watts to each of its four channels into 2 ohms (14.4V, 1% THD).
Use the JX400/4D in combination with our JX500/1D or JX1000/1D monoblocks to build an amazing amplification system at a very affordable price. Or, use the JX400/4D by itself to power two satellites, plus a subwoofer.
The JX400/4D includes a defeatable 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 50-200 Hz.
Dedicated hi-level inputs are included, in addition to conventional low-level RCA inputs, making it easy to integrate with a variety of OEM and aftermarket head units.
