Can the loop cable cause interference to other circuits?
In some circumstances, an induction loop may cause interference in other circuits within a sound system (e.g. a public address system). This is likely to happen if the induction loop cable is installed parallel to, and in close proximity to, audio input cables. Microphone cables are especially vulnerable to this kind of interference. Carefully routing of all cables so as not to run in parallel or cross/touch normally prevents this problem.
