Wireless Interference

Archived from groups: rec.audio.pro (More info?)

Hello, I came across an interesting problem last week at work. In our
smaller recital hall we have an audio rack that contains:

Alesis Masterlink
Tascam CDRW-2000
Panasonic SV-3800
Rane Signal Distributor
2 Neutrik patch bays
Samson wireless receiver
Shure wireless receiver
EV 4 channel mixer
2 Crown amps

the alesis, tascam, panasonic, rane, and one of the crown amps are linked,
and the rest of the equip. is linked.

One day, I opened the CD tray on the Masterlink and the sound of the tray
motor somehow got picked up by the Shure wireless receiver and amplified out
through the speakers. I can't find any logical reason for why that
happened. Any help??

We got the Masterlink this last summer and it didn't happen before that, so
there's something with that...
