JVC KS-DR2104DBT 600W Peak (200W RMS) DRVN Series Class-D 4-Channel Amplifier with Bluetooth Remote General Features JVC DRVN Series Class D 2 ohms Stable 4-Channel Amplifier RMS Power Rating: Total power output: 300 watts Pulse Width Modulated MOSFET power supply Corrosion-Resistant Sealed Cast Aluminum Chassis Polymer Multi-Layer Capacitors are utilized to lower distortion levels The amplifier doesn't corrode in a saltwater environment. Vibration can damage the amplifier if it is not designed to withstand it. This amplifier passes a 3-axis multi-frequency vibration test. Dust entry is restricted to avoid damage to the amplifier The amplifier mounting section is made of 15/64 inch die-cast material to suppress vibration amplification. The thick heat-transfer sheet was placed on the substrate, and the Aluminum die cast heat sink was used to suppress the vibration of the substrate. Thicker terminal connection points and increased wire size enables maximum current flow and higher output for better low-frequency response and cleaner output. A Drain Tunnel Structure creates a gap between the amplifier and the installation surface. This prevents saltwater and sand from accumulating on the bottom, increasing corrosion protection. 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 for the output coils reduces radiated noise, delivering smooth and accurate sound. Qualcomm Bluetooth 5.0 The Bluetooth antenna is housed inside the remote control. This provides a more sensible range for device connectivity, ensuring uninterrupted music playback.
