Hosa CMR210 10ft Y-Cable features a Stereo Mini (1/8") Jack to RCA Phono plugs ideal for connecting an array of gear. Hosa CMR210 splits a stereo Mini (1/8") signal into mono Left and Right. CMR-210 Send Return lead (also known as a Insert Cable), comes conventionally wired: TIP = Send, RING = Return. It can be used as a "Y" to split stereo signal into Left and Right. In this case, Right = RING and Left = TIP.
