Key Features

4 Ch. Class D FullRange Amplifier, 400 W - JL Audio JD400/4

The JD400/4’s controls can be found on the input panel of the amplifier, with all speaker and power connections located along the opposite end of the extruded aluminium 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 convenient feature lets you set your amplifier’s 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.
