Do you have a camera installed in your car and wish you could get the audio from your radio system synced up with the video? Would you like to listen to a second audio input from a RACEceiver or MP3 device all while maintaining perfect communications with your crew? Well guess what? We at Racing Radios have engineered the perfect solution for you. The RRC-AUX-IO is an adaptor cable that plugs inline with your helmet cable. The adapter has a 3.5MM audio input and it also has another 3.5MM audio output for connecting to a camera. The input jack is perfect for connecting a RACEceiver or other listening device for those required to monitor the series' radio traffic. The audio output jack will connect the driver's microphone audio and the Racing Radios in-car radio's receive audio to the camera system. The audio you'll hear on the video is incredible!
