[Ham-Mac] iMic / ACC2 Port

[Dick Kriss, AA5VU]

Lon,

I am very interested in your situation and the solution because I have the
opposite problem with the iMic and the TS-570.  I key my TS-570 via the G4's
USB port that is connected to an iMic and in turn to a SignaLink SL-1 and
have no problem getting sufficient audio to key and drive the TS-570 via the
ACC2 port.

My problem is with the iMic is some kind of impedance mismatch or something
when I take the audio out of the rig to the SL-1+ and in turn to the iMic to
the USB port on the G4.  Audio makes it to the iMic but little or nothing
comes out of the iMic. For this reason I had to bypass the iMic and feed the
Audio to the Line-in port on the back of the G4.

Please keep me posted if you find a solution as I gave up over a year ago.
The iMic did not like the 4.7K Ohm output from the TS-570.
