KS-DR1004D

4-Channel Compact Amplifier for Compact Car, Marine, UTV and Motorcycle / Max Power 400W / 45W RMS x 4 @ 4 ohms


Amplifiers for Marine/MotorSports

Versatile Application

The CS-DR620MBL/CS-DR621MWL offers a tough design that conforms to the IPX5 standard, so you can enjoy high-quality music playback even under the harsh environment of marine and motorsports use. The speakers are also equipped with LED Illumination so you can choose your favorite color that suits your mood or music.

Conformal Coating

A conformal coating is a protective chemical coating to safeguard electronic circuits from harsh environments that may contain moisture or chemical contaminants. It provides a barrier to airborne contaminants from the operating environment, such as salt-spray, thus preventing corrosion.

Circuit Separation Construction

Separated circuit boards of the Pre-amp and Power-amp sections contribute to a reduction in radiation noise.

Large LPF Coil

The large LPF coil provides stable, high quality sound with no distortion even when playing at high volume.

Variable HPF & LPF

Incorporates a rotary type HPF and LPF which enables fine adjustment. Compared with fixed type switching, more precise sound adjustment is possible to match your preferences.
