Stereo Mini to 1/4

Connection: Stereo Mini (headphone or line-out source) to Mono ¼ inch

Plug this into your MP3 Player (headphone or line out jack) (black end to MP3 Player)

and attach coloured ends to this:

Male (pointy) end then plugs into

Channel 1 or 2 (allows control of tone and relative volume from R1 Remote)

-= or =-

Channel 3 or 4 (control from music source)

You could get two RCA to 1/4" adapters, but then you would have to use both channels 3 & 4. Since the L1 is mono, there is no particular reason to use two channels.

(disclosure: I have nothing to do with Radio Shack but they have decent pictures).
