The Roswell Cybox is a Bluetooth receiver that allows you to listen to music on your boat from any Bluetooth enabled wireless device up to 20 feet away. Simply power the Cybox and connect the outputs directly to your head unit or amplifier. Cybox supports aptX , A2DP, and AVRCP profiles optimized for real-time audio streaming. With a built-in line driver, the Cybox produces a line-level output voltage that allows it to function as a standalone unit, eliminating the need for raising the gain settings to unwanted noise levels, and allows your amplifiers to achieve their optimal output. Play your favorite music from your wireless device on your boat's audio system and never miss a beat again.
