JVC KS-DR1004D 4-Channel Marine & Powersport Amplifier - 100 x 4 Watts

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