JL Audio XDM400/4

Discover the XDM400/4, a 4-channel marine amplifier from the renowned manufacturer JL Audio. This device is characterized by its power of 75 watts per channel and delivers extremely low-noise acoustics as well as precise and dynamic sound reproduction. Perfectly designed for use in demanding conditions, the M400/4 is waterproof and therefore particularly durable. In addition, it offers the possibility of implementing a wide variety of setup variants. Its technical equipment and compact dimensions make it the ideal solution for anyone looking for high quality and reliability.

• 4-channel Class D full-range amplifier, 100 W x 4 @ 2 Ω / 75 W x 4 @ 4 Ω - 14.4 V
• This tiny amplifier packs a serious full-range punch, delivering an astonishing 100 watts to each of its four channels into 2 Ω (14.4 V, 1% THD). The breakthrough that allows so much power in such a small package is our NexD ultra-high-speed switching design™ , which enables full-bandwidth Class-D operation with extremely low distortion and excellent efficiency.
• Use the M400/4 in combination with our M600/1 monoblock to build a 1000W amplifier system to power four satellites and a subwoofer... and fit it all under one seat. Or use the M400/4 on its own to power two satellites and a subwoofer. With the M-Series amplifier, the possibilities are endless.
• The M400/4 features a 12 dB/octave filter for each channel bank, which can be configured as a low-pass or high-pass filter and offers a continuous cutoff frequency selection from 50-500 Hz. With the additional HD-RLC remote control (sold separately), the levels of channels 1 and 2 or the overall level of the amplifier can be controlled directly from a remote location.
• This marine amplifier features a white and gray powder coat finish, a sealed control cover, and stainless steel hardware for long life in the marine environment.
