Yamaha CM500 wiring for K2?

wrmoore
Does anyone have the wiring for the CM500 to connect to the K2? Or  
just the pin-out for the CM500 stereo
connector?

Tnx es 73

It's the mic connector I'm asking about. This is probably a dumb  
question, but it's only the second mic I've ever owned in about 45  
years of hamming!

Connect the "tip" of the CM500 mic connector to the mic input pin of the
K2, connect the "ring" of the CM500 mic connector to the +DC pin on the
K2 mic connector through a resistor of about 5K (value not critical),
and connect the "shell" of the CM500 mic connector to the shell of the
K2 mic connector.

Two ways to do this. For both you need to buy an 8-pin connector. Method
1) Cut the connector off the CM500, strip the wires and identify which
color goes to which pin. Strip the wires from the headset and wire them
to the 8-pin connector.  

Method 2) Don't cut any wires. Buy a female 1/8-inch jack from Full
Compass (a very good pro audio vendor in Madison, WI) and make an
adapter.

You'll pay $1.30 for one connector and about $8 to ship it. :)  That's
silly, of course, but it's how life is. So instead of buying only one
connector, think about other connectors you need and stock up. I did
this about two weeks ago and bought ten each of four types of hard to
find connectors.

I strongly recommend method 2. You'll find that this mic and headphones
work really well on a computer, and on the K3. For these uses, you need
no adapter at all -- they plug straight in.

Note that I haven't identified which pins on the K2 connector are which
-- that depends on how you wired it when you built it, so check the K2
manual and your build notes for that detail.
