Portable Loop Systems
Portable loop system for a public building to be DDA compliant
How the portable induction system works
Audible sound reaching the microphone is converted into a small electrical signal and fed into the amplifier. The amplifier then amplifies this signal and feeds this around the room - through the loop cable as an alternating current (a.c.) signal. The bigger the room, the bigger and more powerful the amplifier needed for the job. You will need to measure the room (make measurements and calculate in m2). You can then choose the correct size induction loop amplifier to suit the room size.
Portable loop system (50m2)
The portable loop system is essentially a strong and robust case housing a complete induction loop system. When in use it allows a hearing aid user to hear with ease within a group meeting or at any indoor venue. A radio microphone receiver module is built in to the portable loop system.
What microphone should be used?
A VHF hand held radio microphone can be placed on a microphone floor stand and used at location in the room. For the main person speaking (i.e. lecturer etc) a VHF tie clip radio microphone will ensure freedom of use throughout the room. For meetings a boundary radio microphone can be placed in the middle of a table to pick up sound from around the table at the correct level for the induction loop system to operate. A wired hand held and boundary microphone are available if required. The disadvantage of the wired microphone is the trailing cable in a public area.
Optional extras: loop listener/tester, hand held radio microphone, tie/lapel radio microphone, boundary radio microphone, up to two wired hand held or boundary microphone(s). A maximum of up to three different radio microphones enables flexibility of the system to suit any type of meeting or venue. Only one radio microphone can operate at any one time.
One to one portable loop system
The one to one portable loop system is a self contained all in one system. It has a range of approximatley 1m radius. It can be used in reception areas, meeting rooms, interviews, checkouts, anywhere a one-to-one conversation needs to be held in either a noisy area or where discretion is required. It could also be used in a meeting room for one hearing aid wearer to hear a group of people using additional microphones.
Testing the loop level to British Standards
We recommend you purchase an induction loop test meter. Full instructions are included.
