Audio and loop cables very close

We're just re-doing our church sound system and I was wondering with the induction loop if any laying the loop next to our mic wiring loom (along the floor) will cause any problem hums, buzzes etc?

You can run loop cable next to audio microphone cables AS LONG AS your microphone cables are balanced cables and you are using balanced microphones or DI boxes at the source and balanced inputs on your mixer.

If there are any un-balanced cables or equipment involved you will no doubt have problems. You don't get a hum - instead you get feedback as the signal on the loop couples onto the microphone cable and is then re-amplified.

Remember - you can't put a loop near to an aluminium or metal suspended ceiling as this will stop it working. Also, in the UK it is against wiring regulations to install an induction loop closer than 60cm from mains wiring (including lighting) for long runs.

There is another post in our help pages which expands further on problems you can have with a loop, and why these are rarely actually a problem! Click Here

Hope this helps,
