The only thing I'm using the mic jack for is to activate the PTT circuit. The audio signal is being sent through the 13 pin ACC jack on the back of the radio. I purchased a Timewave 13 pin DIN cable (#40570) and wired a 3 pin XLR plug onto it.
The pins of the XLR plug are:
Pin 1 Ground
Pin 2 Audio +
Pin 3 Audio -
The pins on the 13 pin DIN that are used:
Pin 2 Ground
Pin 11 Audio +
Pin 11 of the DIN cable goes to Pin 2 of the XLR plug.
Pin 2 of the DIN cable goes to Pin 3 of the XLR plug.
The Shield of the DIN cable goes to Pin 1 & 3 of the XLR plug. The jumper between Pins 1 & 3 converts the balanced audio signal of the preamp to an unbalanced signal usable by the 7000.
For PTT activation I used an old Cat5e network cable with an RJ45 8 pin modular plug on it. I wired Pin 4 (PTT) to the Tip, and Pin 7 (Ground) to the Sleeve of the cable to a 1/4" inline jack. Then I plugged a hand switch into the jack.
So:
Audio: Mic<XLR--XLR>ART IN/ART OUT<XLR--DIN>IC7000 ACC Jack
PTT: Handswitch<1/4"--RJ45>IC7000 Mic Jack
Hope this helps...
