Congratulations on purchasing your LA-215

loop ampliﬁer. You have chosen a modern

and reliable system.

Please read through these operating in-

structions carefully. They tell you how to set

up the system correctly and explain all the

system’s features to you.

Standard components

Please check if all following components are

included:

- LA-215 loop ampliﬁer

- Power cord

- Stand

- Microphone cable

- 37 m of loop cable and cable clips

- Connection cable set

- Operating instructions

- Guarantee card

If any parts are missing, please immediate-

ly contact your dealer or the manufacturer

directly.

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.

10 English

Button for the automatic gain control

AGC (8):

If this function is activated, the volume in the

induction loop will be limited to the volume

selected with the volume control.

This eliminates the needs to constantly ad-

just the volume for different pro

grams.

Line input selecting button LINE (9):

If you connect 2 audio sources to the LA-215,

you can press this button to select the sig-

nal you want to hear. When the ampliﬁer is

switched on, line input jack A (14) is always

active initially. Press this button to activate

line in B (13). This function is only available

for the LINE input jacks.

Back panel

LINE input level control - LINE INPUT

LEVEL (12):

This control knob can be used to set the

overall volume of the input signal. In addi-

tion, the volume can be adjusted between

the line and the microphone inputs.

Installation

1 Use the connection cable included with

the device to connect an audio source

to one of the two line in jacks (13, 14) on

the back panel (Fig. B).

If your television set or your sound

source is not equipped with a direct

connection, use the microphone, which

you can insert into one of the two micro-

phone jacks (15, 16).

2 Connect the two ends of the loop (Fig.

A) with the input jacks (11). Press the

red and black button to insert the cable

and release the button to lock it in place.

Make sure that only the not insulated

part of

the cable is clamped into the con-

nections.

To remove the cable, press the

button again and pull the cable out.

Operation

1. Before you insert the power cord into

the designated socket on the rear panel

of the inductive loop ampliﬁer, set the

volume control to its lowest setting.

2. Press the Power on/off button (7) to

switch the loop ampliﬁer on.

3.

Now anyone wearing a hearing aid must

set it to the T or MT position.

4. Adjust the volume control to the desired

volume.

Important: Before you connect or discon-

nect an audio source, always pull the power

cord out of the wall outlet.

Troubleshooting

No sound

- Check to make sure that all the cables are

connected properly.

-

Make sure that the ampliﬁer is switched on.

- Make sure that the hearing aid is set to the

“T” or “MT” function.

- Make sure that the volume is set correctly.

Volume level is not loud enough

- The volume control is set too low. Turn

up the volume on the ampliﬁer.

- The Line Input control is set too low. Turn

up the Line Input control.

- Make sure that you are sitting up fairly

straight. The more you lie down, the wea-

ker the signal will become.

Sound distortion

- Loop volume is set too high. Turn the vol-

ume down.

- Connection cable is damaged. Replace

the cable.

Background noise (humming)

- Switch the loop ampliﬁer off and if the

noise continues, this indicates interfer-

ence caused by another device, such

as the TV, neon lights or dimmer switches.

- If the noise disappears when the loop

ampliﬁer is switched off, the problem

might be a system error, a damaged

microphone cable or a noise that is being

transmitted by the microphone.

Maintenance and care

The LA-215 loop ampliﬁer does not require

any maintenance. If the unit does become

dirty, simply wipe it clean with a soft, damp
