i posted a while back about a problem with recording on one channel of a
masterlink via peavey vmp2

i fixed the problem, but i'm still curious about it. the problem was that
even in recording just one channel i would get signal on both channels, and
both channels sounded crackly.

the masterlink has two sets of inputs, rca and balanced xlr.

the recording setup being used is attached to a consumer stereo system with
cassete, phonograph, and cd.

both sets of inputs on the masterlink were connected. and i have the same
setup at home with a masterlink and stereo system.

turns out that somehow the masterlink was using both sets of inputs at the
same time. i would think there would be some sort of automatic defeat so
that it would only use rca or xlr at any given time. and i have never had
this problem at home, but it seems that with this setup there was some
signal coming off of the amp and into the rca inputs. i disconnected the rca
input cables to the masterlink and the crackling went away

any ideas on why this happened?

Don't do this.

Because the inputs are paralleled.
