Hearing loop problem
Neil Coode from Cranleigh in the UK asked us for help with a T-Loop problem. He says:
“We have a rather nice hearing loop installed in our church. We also use one or two (depending on band) older wedge speakers for foldback. Unfortunately the wedges pick up signal from the hearing loop which causes problems with distortion and feedback. How do we solve this without spending loads of cash on individual foldback monitors?”
We asked Pat Smith from SFL Group to respond:
It is difficult to fault find an issue like this at a distance without knowing significantly more about their set-up, but we can give some hints.
It is extremely unlikely that the loop is interfering directly with the foldback monitors so buying new monitors is unlikely to help with the issue. It is more likely that the loop is interfering with one or more of the sources which they happen to be feeding into the monitors. The prime culprits are usually electric or bass guitars. The pick-ups in these instruments work on the same principles of electromagnetic induction as hearing loops, so these will pick up signal being transmitted via the loop. If these are feeding back into the monitors you will hear content from the loop in the monitors via this route. Read More
