Using an inductive loop system, hearing-aid wearers can pick up the signals emitted by electric/ electronic audio sources (microphone or hi-fi systems) directly in their hearing aids or CI systems.
As a result, they hear the sound without any annoying background noise, echo or reverberation. An outstanding advantage of using induction loop systems: no special receivers are required. All that?s needed is the hearing aid.
Most modern hearing aids are now equipped with adjustable M and T functions. M stands for microphone, i.e. hearing thesound in the room via the integrated microphone, and T (telecoil) means that the audio signals are transmitted inductively and directly
via a telecoil integrated in the hearing aid. Some hearingaids are also equipped with an ’‹MT’½ function, which combinesboth types of reception, microphone and telecoil so that thelisteners are able to hear the sound in the room as well as the
inductively transmitted signals.
Alternating current creates a magnnetic fi?eld in a wire/a loop. If a second wire is introduced into this magnetic field (here: the telecoil in a hearing aid), a correspondingly alternating current will also be created in it: the electrical impulses are induced into the second
wire without any actual electrical connection.
An induction loop system consists of a loop and an amplifier. The loop, an insulated wire, runs around the outside of the listening area. Theamplifier, connected with an audio source (hi-? system, speaker?s microphone, etc.), transmits the acoustic signals converted into
alternating current to the loop.
The magnetic field inside the loop allows the listeners tomove freely in the room and pick up the audio signals fed directly into their hearing aids.

The PROLOOP amplifier family is designed for professionaluse in medium-sized rooms (up to 170 m2) in private buildings and public facilities, in which particularly high dependability and extremely reliable operation are required.
With its 100-percent short-circuit proof amplifier, programmable, balanced XLR input jacks and highly stable output power, the PROLOOP C is able to meet these demands.Automatic Gain Control (AGC) guarantees consistent field strength and reproduces stable sound with a special emphasis on clear speech, even under acoustically demanding conditions. The integrated monitor output and corresponding testing technology can be used to analyse the induction loop audio quality
Higher output power: 11 A RMS / Short-circuit-proof
Automatic fuse reset / Two programmable, balanced XLRinputs
One phono input / Two line outputs
Extra-sturdy jacks / Dual action AGC for excellent speech recognition
High availability, operating reliability and quality assurance
Convenient monitoring of the magnetic field: Can be done using headphones or speakers
Treble control to compensate for treble losses due to reinforcement

RETURNS POLICY
To return goods we have delivered to you, please contact us within 30 days from the date you have received the item. A staff member will then assist you with any return or repair. This may include inspecting the goods, arranging for the goods to be sent for repair, or providing you with a replacement.
Incorrectly Ordered/Change Of Mind:
Refunds are not normally provided where you have simply changed your mind or found the goods cheaper elsewhere. However, if goods have been incorrectly ordered, at our discretion, customers may be credited less a restocking fee.
A change of mind return will only be accepted if:
Please note: For change of mind returns, the shipping cost and method is the customer's responsibility. We will not compensate any returns that are lost or damaged in transit to us. For some change of mind returns, a restocking fee may apply.
Faulty Items
We recommend you immediately inspect any goods that we deliver to you or that you collect from our store to ensure you are completely satisfied with the goods. If any goods arrive damaged, please contact us as soon as possible. We will arrange to have the damaged goods returned and either arrange for a replacement of the goods or refund. Replacements and refunds of new products that are damaged on delivery or faulty from new requires a proof of purchase of the product and be returned with all original packaging, accessories and/or manuals included. Refunds will be made via the method of payment you used to make your purchase. If we consider the goods to have breached a consumer guarantee, any shipping costs to return the goods to us will be at our cost and compensated.
Repairs
The product must be returned with proof of purchase, it must not be modified or mistreated in any way and it must not have been serviced elsewhere. Goods returned for repair will be assessed and/or repaired within a reasonable time. You may be required to pay labour, assessment and/or freight fees, such as where goods are assessed to have been damaged by misuse or accident. We may provide you with an approximate fee; this may vary due to reasons beyond our control. In some circumstances, goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the goods.
Estimated Delivery Time Frame: 4-8 business days
