So can you confirm if the CL2 wire is the better solution? What If I decide to use the CL2 to plug into a audio mixer getting a line feed out to the transmitter during a live band shoot. Will that work?

NO - this is *not* the CM-1 wiring!

The CM-1 has an additional capacitor in the XLR - this prevents the 5V plug-in power from the transmitter going to the microphone and causing problems.

You are then plugging in the mic. to the line input - so you have to turn up the gain and get more noise.

It sounds like you have a CM-1 cable without the blocking capacitor that is causing the problems.

Yes - if you cut off the rt.angled mini-jack and replace it with a female XLR and don't forget the blocking capacitor.

No - the CL-2 is a line input cable and should not be used for a microphone as it is connected to the line/instrument in of the transmitter.

Yes - that's fine.

Even with the CL-2 line input cable, I'm not sure the body-pack transmitter can 'handle' +4dB. -10dB is no problem, so use the board's RCA outs. Or better yet, use an pre-fader aux out for an independent of house mix, Just turn down the aux, master to lower the output some.

I'm on a slow and expensive roaming link now, so I can't check the actual figures.

But the input level *is* adjustable on the transmitter.

If the SK-100 transmitter's sensitivity adjustment does not control the transmitter's front-end input stage, it could distort regardless of the sensitivity adjustment setting. I recall having to pad down a +4 input a few dB to avoid some quite audible clips with the sensitivity set at -30 db.
I can't find any line-in dB range in the manual's specs or if the CL-2 cable has a built-in pad, so you may be very well correct John.
