JL Audio RD400/4 4 Channel Amplifier

The JL Audio RD400/4 4 channel amplifier is small, sleek and amazingly powerful and versatile.  Using NexD switching technology, this 4-channel car amplifier gives you 100 watts of clear RMS power from each of its four channels. You can also choose to bridge it to produce 3-channel or 2-channel power. That’s what has made this a popular choice for many applications at Audio Express / Quality Auto Sound.

JL Audio has packed the RD400/4 with studio-grade signal processing features such as high or low-pass defeat able 12 dB/octave filters for each channel pair, and dual-range, differential-balanced inputs designed to clean stray noise from the signal. Automatic turn-on, using signal sensing or DC-offset sensing, is standard equipment. Pass-through preamp outputs make it easy to integrate this amp into a system.

The black powder-coated case features all of the controls on top of the amplifier, beneath a protective cover, with all connections located along one side of the chassis. Top-mounted, dual-color LEDs report the overall status and condition. Onboard LED-clipping indicators let you easily set your amplifier’s input sensitivity quickly and accurately with no special equipment needed.

If you want big power, total control and lots of flexibility, let the experts at Audio Express / Quality Auto Sound introduce you to the JL Audio RD400/4 4 channel amplifier.
