Tone Control

Use to vary the tone of the signal. Turned in the clockwise direction

the higher frequencies will be emphasised and in the anti-clockwise

direction the lower frequencies will be emphasised. As the tone

control is moved the blue light will travel around the control indicating

the tone position in use.

Loop Level Indicator

This indicates that a signal is being transmitted by the loop cable. It

flickers with a low volume and remains steady with louder volumes.

Testing the system can be done by speaking into a microphone and

seeing the light flash, this will indicate that a signal is flowing round

the cable.

Sound Source Selections

Pressing one of these buttons will select the sound source connected

to the hearing loop driver in the corresponding sockets on the rear of

the hearing loop driver. One or more of these can be selected at any

one time. When the channel is selected a blue light will show in the

button. Press the button again and the light will go out showing that

channel is off.

Microphone

Selecting this will allow sound from connected microphones. If a

microphone is plugged into socket B and the priority button is pushed

in then any sound received by this microphone will override all the

other sounds connected to the loop system. This can be useful when

used to monitor a doorbell or telephone bell or if a partner wants to

talk to the hearing aid wearer through the loop.

Analogue Line Input Aand Analogue Line Input B

Allows the selection of the line input signals from channel A or B.

Useful to connect to a TV and DVD player so that either may be simply

selected from the front panel. Either or both channels may be selected

simultaneously.
