JVC KS-DR2104DBT Marine Powersport 4-Ch Amplifier w/Bluetooth Controller 50W x 4

IP67/IP66 Waterproof & Dustproof

IPX6: Protection against Powerful Water Jets / Water projected in powerful jets, up to 12.5mm (0.49 inch) against the amplifier from any direction shall have no harmful effects.

IPX7: Protection against Immersion, up to 1 m (3 feet, 3 inch) depth / Restricts harmful amounts of water entry when the amplifier is immersed in water under defined conditions of pressure and time, up to 1 m (3 feet, 3 inches) of submersion.

Dust Tight

IP6X: Effective against Dust-tight / Dust entry is restricted to avoid damage to the amplifier.

ASTM B117 Rustproof

Saltspray-proof: ASTM B117 salt spray (or salt fog) corrosion test simulates harsh conditions in a saltwater environment to ensure the amplifier does not corrode or fail in these harsh conditions. By adopting the Corrosion-Resistant Sealed Cast Aluminum Chassis and stainless-steel screws resistant to rust and corrosion, this amplifier achieves the highest level of durability in its class.

Vibration-proof

Vibration-proof: Vibration can be damaging to amplifier if it is not designed to withstand it. This amplifier passes a 3-axis multi-frequency vibration test.

15/64 Inch Die-Cast Material

The amplifier mounting section is made of 15/64 inch die-cast material to suppress the amplification of vibration. In addition, the thick heat-transfer sheet was also placed to the substrate and the Aluminum die cast heat sink to suppress the vibration of the substrate.

Increased Power Flow

Thicker terminal connection points and increased wire size enables maximum current flow and higher output for better low frequency response and cleaner output.

High Quality Capacitors

High Quality PMLCAP’s (Polymer Multi-Layer Capacitors) are utilized to lower distortion levels, improving the overall listening experience at higher volumes, while maintaining the integrity of the sound.

Magnetic Shielding

Magnetic Shielding for the output coils reduce radiated noise, delivering smooth and accurate sound.

Waterproof Bluetooth Remote Control

The Bluetooth antenna is housed inside the remote control. This provides more sensible range for device connectivity, ensuring uninterrupted music playback.
