I have a couple SC systems with SC1 body packs. I have a WA300 instrument cable. Is this compatable with the SC1? Your info lists the WA302. Can you send me a wiring diagram of the WA300 and/or the WA302?
The WA300 is not compatible with the SC1.

The wiring diagram of the WA300 can be seen on page 4 of the L Series User Guide. The L Series User Guide can be found in the User Guide section of the Shure website.
