For my PW Plus II's to Alienbee setup, I have two 1/8 to 1/8 mono 6' cable (a shorter length was not available).
I bought two. One works great. The other, purchased a week later, eh, not so much. In fact, not at all.
I can't see that this is an AB or PW issue, so I have to assume it's with the cable.
Anyone care to chime in?
