How it works

The LA-215 picks up signals from an audio

source that is directly connected with the

device with a lead or via a microphone.

A magnetic ﬁeld is created in the loop. With

the help of a hearing aid equipped with an

integrated teleloop or an inductive receiver,

you can hear the ampliﬁed audio signals

(TV, radio, microphone) at the volume of

your choice.

Display and operating elements

Front panel

Power on/off (7):

Press this button to switch the LA-215 on

and off.

Once you have switched the device

on, the indicator will light up and the line in-

put jack A (14) is active.

Volume control VOLUME (1)

Tone control (treble/bass) TONE (2)

Headphone connection jack (3):

To connect a headphone with a 3.5-mm

jack. This makes it possible to check the

ampliﬁer’s output signal even if a loop is not

connected.

LOOP LEVEL indicator (4):

This indicates that a signal is being trans-

mitted 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.

If one of the following buttons is pressed,

the corresponding light-emitting diode

(LED) will light up to indicate which function

has been activated. If the button is pressed

again, the indicator will go off.

Microfon button MIC (5):

Press this button to reduce the background

noise in noisy rooms.

Priority button PRI (6):

A signal detected on microphone input B

(15) will be treated as the priority signal. This

makes it possible to monitor a doorbell or

a telephone. If this function is switched off,

both microphone inputs will be processed in

the same way.
