JVC KS-DR2104DBT Marine Grade 4-Channel Amplifier w/ Bluetooth

Description:4-Channel Compact Digital Amplifier featuring Bluetooth for Compact Car, Marine, UTV and Motorcycle / Max Power 600W / 50W RMS x 4 @ 4 ohms - IP67/IP66 Waterproof & Dustproof - IPX6: Protection against Powerful Water Jets / Water projected in powerful jets, up to 12 ...Description:4-Channel Compact Digital Amplifier featuring Bluetooth for Compact Car, Marine, UTV and Motorcycle / Max Power 600W / 50W RMS x 4 @ 4 ohms - 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. - IP6X: Effective against Dust-tight / Dust entry is restricted to avoid damage to the amplifier.

- A Drain Tunnel Structure is employed for creating a gap between the amplifier and the installation surface. This prevents saltwater and sand from accumulating on the bottom, increasing corrosion protection. - 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-proofVibration-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. - 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. - Sound Optimization - 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 PMLCAPs (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.GeneralWaterproof Bluetooth Remote Control - The Bluetooth antenna is housed inside the remote control. This provides more sensible range for device connectivity, ensuring uninterrupted music playback. - Qualcomm Bluetooth 5.0This premium Bluetooth solution delivers high-quality wireless audio performance for apt - X and AAC codecs.

- Versatile Installation - Multiple installation options are available, giving you complete control where you want it. - Easy-to-Use Remote Control - Enhanced fine-tuning controls are available for installation and setup flexibility. - Specifications:Audio unit - Max Power Output: 600WRated Power Output:Stereo (4Ω): 50W x 4 (20Hz20k - Hz, 1.0% THD)Stereo (2Ω): 75W x 4 (1k - Hz, 1.0% THD)Bridged (4Ω): 150W x 2 (1k - Hz, 1.0% THD)Speaker Impedance: 4Ω (2Ω to 8Ω allowable) (Bridged connection: 4Ω to 8Ω allowable)Frequency response (+0, 3d - B): 10Hz20kHzSignal to noise ratio: 89d - BLow pass filter frequency (12d - B/oct.): 50Hz200Hz (variable)High pass filter frequency (12d - B/oct.): 50Hz200Hz (variable)Preout: 5V (Max)Bluetooth - Version: Bluetooth Ver.5.0
