4-Channel Amplifier
KS-DR1004D
4-Channel Compact Amplifier for Compact Car, Marine, UTV and Motorcycle / Max Power 400W / 45W RMS x 4 @ 4 ohms
Versatile Application
Receivers and amplifiers for marine and motor sports applications need to perform in harsh environments exposed to outdoor elements. JVC’s marine and motor sports receivers and amplifiers feature compact size for versatile installation even in tight spaces. Conformal coated main PCBs (printed circuit boards) offer additional protection against moisture and condensation from damaging the product.
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.
