Installing temporary induction loop systems
A properly installed system is capable of giving very high quality levels of reproduction. The key to this is careful consideration of some basic guidelines. Here are some key points to consider:
- Determine the approx. area you need to cover - One of our loop amplifiers will cover up to 550 sq metres.
- Is the area to be covered likely to include a high degree of metalwork - i.e. does the floor contain reinforced concrete? - for example, the floor of an exhibition centre. Large amounts of metalwork will significantly reduce the level of a loop system necessitating higher drive currents or reduced coverage.

- Is there an adequate sound system in place capable of driving the loop system? You may encounter problems with a sound system that has unbalanced microphone lines.
- Are there a significant number of halogen lights in the facility? Some electrical installations create 'hum loops' at mains frequency that would interfere with a hearing aid.
- Some musical instruments and dynamic microphones will pick up a loop system, causing interaction between the loop system and a P.A system. Where possible, avoid using dynamic microphones and keep instruments outside the loop.
- For multiple loop applications, think about the physical location of rooms. Remember - conventional loop systems will radiate up to three times their own area.
