  • RD 400W 4-channel full range amplifier in Class D
  • The top seller of 4-channel amplifiers at JL Audio!

Test result:

  • Test in Car & Hifi 2/2017 - top class - grade 1.4 - purchase value: very good

Features:

  • 4-channel full-range amplifier Class D, 100 W x 4 @ 2 Ω / 75 W x 4 @ 4 Ω - 14.4V
  • Using JL's exclusive NexD™ high-speed switching technologies, the ultra-compact RD400/4 amplifier is designed to deliver high audio output power with incredible efficiency and low distortion.
  • The RD400/4's controls are on the top of the amplifier under a protective cover, with all connections located on one side of the chassis.
  • Studio-quality signal processing features include high-pass or low-pass filters with 12 dB/octave (disengageable) for each pair of channels with continuous frequency selection from 50 to 500 Hz and differential balanced
  • An automatic power-on function (via signal sampling or DC offset sampling) is standard, along with all-new input switches for bridging stereo output channels without the need for Y-adapters.
  • Integrated LED clipping indicators are also included with the RD400/4. This all-new, innovative feature allows you to quickly and precisely adjust the amplifier's input sensitivity settings without the need for special equipment.
  • A set of preamplifier outputs is also available, so that one can effortlessly route the signals to another amplifier.
  • The RD400/4 features a durable black powder-coated finish and a top-mounted, two-color LED light bar that indicates overall status and condition.
