Stand for LA-215 ————

Congratulations on purchasing your LA-215 loop amplifier. You have chosen a modern and reliable system.

Please read through these operating instructions 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 immediately 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 input 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 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.

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.

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 adjust the volume for different programs.

Line input selecting button LINE (9):

If you connect 2 audio sources to the LA-215, you can press this button to select the signal 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 addition, 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 microphone 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 connections. 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 disconnect 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 weaker the signal will become.

Sound distortion

• Loop volume is set too high. Turn the volume down.
• Connection cable is damaged. Replace the cable.

Background noise (humming)

• Switch the loop amplifier off and if the noise continues, this indicates interference 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.
