LA60 Loop Amplifier
Owner’s Manual
Introduction
The LA60 Loop Amplifier provides a practical solution for hearing aid users to
listen more easily to conversation or other audio sources via the “T” or “MT”
facility of their aid.
The amplifier unit picks up sound via a microphone or direct connection lead and
sends the signal to a loop placed in the listening area which transmits the sound
inductively, “magnetic sound waves”, to the hearing aid.
Functions
1)
POWER:- This light will be on constantly while power is being supplied to the
system.
2)
LOOP DRIVE:- This light shows that a signal is being passed from the
amplifier unit to a loop and that the loop is continuous.
3)
OVERLOAD:- If the red light is illuminated constantly, adjust the volume
control until the red light is just flickering giving the maximum undistorted
output.
4)
VOLUME:- This controls the volume level for the user.
5)
BALANCE:-
•
This control balances the total level of the output signal between the two
inputs.
•
If using only one microphone ensure that you adjust this control to give the
maximum output signal.
•
Turn the balance control clockwise for channel 1 (mic 1), and anticlockwise
for channel 2 (mic 2).
•
If using both Microphones use the balance control to get optimum
performance from both microphones.
•
Each microphone channel can alternatively be used as a line input for
connection to other audio equipment. (If using this method turn the balance
control away from the input being used).
