I'm looking for a CD player that can be remotely started (play) with a
simple short circuit. I've looked into the Gemini product but their
"control" cord has eight pins and it'll take some time to find out what
combination starts the CD player. Any/all information would be much
appreciated.
Thank you

The service manual should tell you which pin is which.

Denon makes some broadcast machines with remote relay start for connection
to broadcast consoles. So does Teac. You'll still need the manual to hook
them up, though.

A lot of folks hack up consumer machines with outboard jacks connected to
the play button.

I do it the cheap and dirty way which works with almost every machine
on the market. For about $5 parts and 30 - 60 minutes do the
following. Just about every play button is merely a switch that is
soldered to a circuit board somewhere. Solder a pair of wires to
these 2 points on the circuit board using some strain relief so it is
sturdy and bring them to a 1/4 unbalanced jack mounted anyplace on the
back of the unit. Make sure the grounded side of the switch is the
one that is touching the chassis on the 1/4 jack. You can then run a
1/4 plug to wherever you have a closure to start the machine.

Most CD players will automatically play the disk in the tray when they are
turned on.

If that's all you want to do, all you need is a power switch.

PS: If you use the "two wires across the Play button" solution, you'd be
better off using a FET and a logic gate to short the switch, rather than two
"nude" wires. It's better to provide a bit of isolation; you never know
what's going to come down those dangling control wires.

I guess you're right, but I've done it this way 25 or 30 times and
never had a problem over a 10 year period. That's a pretty good track
record. The rest of the system is always grounded properly and the
device supplying the closure is usually a TTL or open collector type
device designed for this purpose although I have used a simple contact
relay at times too.
