1.4. General information
The PROLOOP LOSplus amplifier has been designed for use in professional venues where high reliability and
safe operation are essential. The 100% short-circuit-proof amplifier with its extremely stable output power meets
these requirements.
1.5. How it works
The induction loop amplifier generates an alternating electromagnetic field around the loop cable. The loop con-
sists of an insulated wire, which is usually laid singly (or doubly) along the side of the room. When the hearing
aid user sets the hearing aid to the "T position", voltage is induced within the T coil. This voltage depends on the
amplifier's input signal. Now the signals are amplified by the hearing aid and converted into sound. The alterna-
ting electromagnetic field inside the loop allows the hearing aid user to move around freely within the room and
to receive the voice- or music signals as pleasant high-quality sound, free of environmental noise.
1.6. Notes on safe operation
This device complies with all the necessary EU directives and bears the CE seal of approval. To make sure that
your device enjoys a long service life, please observe the following information.
To prevent accidents or personal injury caused by electrical shocks, never place any type of container
filled with a liquid, such as a vase, on the device.
Never pull on the power cord to remove the plug from the wall outlet; always grasp the plug directly
and pull it out.
Do not operate the device near heat sources or in rooms with high humidity (operating temperature
range 0-40°C).
Do not cover the air vents so that any heat generated by the device can be dissipated by air circulation.
Depending on how it is used, the device can develop high temperatures in the heat sink and at the air
vents. Be careful not to touch these elements by accident – risk of burns !!!
Do not use the device:
• if the power cord or the plug are defective or damaged.
• if the device is not functioning properly or is defective.
• if the device has been dropped or damaged in any other way.
To clean the device, simply wipe it with a soft, dry cloth – never use any kinds of chemicals or water.
Should a repair become necessary, have this done by an authorized technician only.
