The HVC-2800 camera was one of the few that featured separate input jacks for adding stereo audio. Mounting a stereo microphone in the accessory shoe and plugging in the mic cables produces two separate audio signals from the camera head. Incorporates a K-type plug and cable. When used with a SLO-420 it can record dual audio on its two linear tracks. Can also be used with the HVC-220 Camera Adapter to break out the stereo lines. This allows it to be used with any stereo VCR with dual inputs.
