Am I legally obliged to have assistive listening?
Yes. Assistive listening is not simply a good thing to have for all businesses, it's a legal requirement under the Equalities Act 2010
Can I use a standard, everyday audio amplifier to drive an induction loop?
No. You won't be able to meet the performance standard , the frequency response will be very poor, and hence the sound will be unintelligible.
There is a whistling sound similar to acoustic feedback when I use microphones together with a loudspeaker system. What have I done wrong?
There are three general causes:
- Loop grounded to earth
- An earth loop
- Cross talk from low level signal cables or dynamic pick ups as used in electric guitars and some microphones.
Cross counter systems
There will be a goose neck microphone on either side of bullet proof glass, the receptionist will speak into it via the induction loop for the hearing impaired and speakers will be placed on the counter for those with normal hearing.Can we connect two microphones to the loop amp? Or will one cancel the other out?
Yes, for DLS-50 and DLS-70 there are 2 microphone inputs, but if you are using the DLS-50 there is one special microphone input that has a controllable gain.
Please use that for the main microphone and for the second microphone (we normally recommend only one to keep the acoustic noise down), other combined microphone and line input. All the inputs have phantom voltage to the microphones.
If using the DLS-70, there are two microphone inputs with just the AGC-regulation function. This normally works well but cannot be fine tuned for exact sensitivity and background acoustic noise.
FM Systems - OKAYO
Does the OKAYO system have diversity?
Yes the EJ-700 series of receivers have diversity.
