JL98621 – 4Ch. Class D Full-Range Amplifier, 400 W

Model No: RD400/4

Description

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

Utilizing our exclusive NexD™ high-speed switching technologies, the ultra-compact RD400/4 amplifier is engineered to deliver loads of audio output power, with incredible efficiency and low distortion. Don’t let its modern styling and small size fool you though, this little powerhouse churns out 100 watts of crystal-clear audio from each of its four channels into 2 ohms (14.4V, 1% THD) and is fully bridgeable, so it can be used as an 3-channel amplifier, or as an 2-channel amplifier producing an whopping 200W x 2 into 4 ohms.

For your convenience, the RD400/4’s controls can be found on top of the amplifier, beneath an protective cover, with all connections located along one side of its chassis. Studio-grade 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 most input voltage levels. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard equipment, along with all-new input type switches for bridging of stereo output channels without needing to use Y-adaptors.

Onboard LED-clipping indicators are also included with your RD400/4. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity settings, quickly and accurately, with no special equipment needed. You’ll also find an set of preamp outputs on-hand, so you can pass signals to another amplifier, almost effortlessly. The RD400/4 features an durable, black powder-coated finish and an top-mounted, dual-color LED light strip that reports the overall status and condition.
