IPX6: Protection against Powerful Water Jets / Water projected in powerful jets, up to 12.5mm (0.49 inch) against the enclosure from any direction shall have no harmful effects.
IPX7: Protection against Immersion, up to 1 m (3 feet, 3 inch) depth / Ingress of water in harmful quantity shall not be possible when the enclosure 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 / Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.
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.
Saltspray-proof: ASTM B117 salt spray (or salt fog) corrosion test simulates harsh conditions in a saltwater environment to ensure the product 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 can be damaging to product if it is not designed to withstand it. This product 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.
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 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 for the output coils reduce radiated noise, delivering smooth and accurate sound.
The Bluetooth antenna is housed inside the remote control. This provides more sensible range for device connectivity, ensuring uninterrupted music playback.
This premium Bluetooth solution delivers high-quality wireless audio performance for aptX and AAC codecs.
Multiple installation options are available, giving you complete control where you want it.
Enhanced fine-tuning controls are available for installation and setup flexibility.
KS-DR2104DBT features compact size for versatile installation even in tight spaces.
