Microphones

A microphone is perhaps the most important link in an audio chain.

As the connection between the sound source and the sound system, it must interact efficiently with both.

Choosing this link successfully requires knowledge of the sound source, the sound system (including the room acoustics), microphones and the actual application.

A number of microphones are available from SigNET for use with its induction loop systems (see our Microphone Selection Guide below).

Loop Testing Equipment

SigNET recommends all its induction loop systems are tested using a ‘Fosmeter Pro’ Induction Loop Test Kit (FPROK1).

Designed to simplify the setup of an induction loop system to the latest version of BS EN 60118-4 (Magnetic field strength in audio-frequency induction loops for hearing aid purposes), the kit includes an FPRO Fosmeter Pro induction loop tester c/w intuitive display and simple to follow test menus, a calibrated signal generator c/w pre-loaded test tones and a set of headphones.

As well as checking the magnetic field strength of an induction loop system, it also measures background noise, frequency response, metal compensation AND allows you to listen to the loop signal.

The tester and signal generator are each powered by a 9V PP3 battery and both are supplied in protective canvas carrying cases.

Loop cable & Ancillaries

SigNet can supply two types of Induction Loop Cable:

  • 100m reels of single core loop cable (0.5mm2, 1.0mm2, 1.5mm2, 2.5mm2)
  • 100m reels of flat copper foil tape (0.5mm2, 1.0mm2, 1.5mm2)

Copper foil tape is typically used for floor loops under light duty carpets. Protective tape is also required to hold the cable down and reduce the likelihood of damage. Copper foil tape should be connected to the loop amplifier using solid 0r 1A ‘choc’ block.

Note: The chemical elements of some self-levelling floor compounds can react with the pastic covering of copper foil tape. If installing the loop under such a compound, we recommend you check compatibility by testing a small piece of tape with the compound and check for adverse reactions.
