Overview

4-Channel Class D Full-Range Amplifier, 100 W x 4 @ 2 / 75 W x 4 @ 4 - 14.4V

UtilizingJL Audio'sexclusive NexD high-speed switching technologies, the JD400/4 amplifier is engineered to deliver loads ofcleanpower, with excellentefficiency and low distortion. This little guychurns out 100 watts of audio from each of its four channels into 2 ohms (14.4V, 1% THD) and is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a whopping 200W x 2 into 4 ohms.

TheJD400/4s controls can be found onthe input panel of the amplifier, with all speaker and power connections located along the opposite end of the extruded aluminum chassis. Signal processing features include high or low-pass 12 dB / octave filters (defeatable) for each channel pair, with continuously variable frequency selection from 50-500 Hz, and dual-range, differential-balanced inputs capable of accepting line-level or speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard equipment.

Onboard LED-clipping indicators are also included surrounding each input sensitivity control. This convenientfeature lets you set your amplifiers input sensitivity, quickly and accurately, without special equipment. You will also find a set of buffered, pass-through preamp outputs on-board, so you can pass signals to another amplifier.
