Why Univox Induction Loops

online-broschyrLoop systems are often the most practical, cheapest and lowest maintenance solution for giving good quality access to the hearing impaired, and is therefore becoming the most widely used solution around the world.

Once installed a induction loop works for years without any maintenance cost for the owner of the venue. And not to forget – the hearing aid wearers do not need to pay for any extra receiver – the receiver is already built-in in their hearing aid! They just switch their hearing aids to T-position and enjoy the sound. That is real freedom! To bring back this freedom to the hearing aid users has always been the most important goal for us.

With our strong belief that a induction loop is the best solution to transmit sound to hearing aid users we are constantly developing our products which improve the life of millions all over the world. Univox loop systems are designed to always supply enough power to really make a difference. Many can build loop amplifiers but only Univox has the technical know-how, design expertise, long experience and manufacturing skills to build the most powerful induction loop amplifiers in the world. After having developed the very first specially designed constant current loop amplifier 1969 Univox has been the industry leader in induction loop design. Today 15,000 Univox loop amplifiers are sold annually.


Unfortunately there are many induction loops installed around the world that are not powerful enough to make hearing aid users really hear what is being said. The reason is often pour planning and/or installation of the system, but another common fact is that the amplifier itself is too weak to produce the current needed to create the necessary magnetic field strength. The system simply has been under-powered, mostly due to economical restraints or induction loop suppliers promising one thing but supplying another.


At Univox we don’t play that game. We know there is no substitute for power and our amplifiers are always built to give that necessary power to the system: A combination of very high voltage, super-high current and strong long-lasting casing make our loop amplifiers unparalleled in the world. We have not experienced any amplifier that is even close to bring the amount of current that Univox amplifiers do – always and everywhere.

Automatic Gain Control

Unfortunately it doesn’t stop by power. Power alone is not sufficient. Power is necessary but has to be combined with a comprehensive way of managing the sound output in the loop to compensate for varying input levels. The unique Dual Action Automatic Gain Control (AGC) built into every Univox amplifier is still unrivalled in this respect. Two separate systems, one handling the input levels and the other managing the output levels work flawlessly together to bring an absolute smooth sound experience to every user. No sudden sound bursts and no long gaps make it a true pleasure to listen to the sound of a Univox induction loop system.

High quality

The Univox position on the market has been achieved by technical excellence, a unique market presence and a lot of hard work. Since the mid-eighties we have a close and fruitful relationship with our Taiwan based manufacturer and increasingly they act as an integral part in our product development. This symbiotic co-operation allows us to improve our high product quality further and further every year and gives us an unrivalled development pace. We firmly believe that by keeping this high-quality setting we will keep our product quality at the level we wish and our customers deserve. We will never compromise with that!

IEC 60118-4

Since many years Univox plays an important role in the international development of the IEC standard on the measurement of induction loops, IEC 60118-4. Our owner and technical manager Mr. Conny Andersson has for several years been the convener of the IEC committee and with his deep technical expertise combined with an unique experience of the conditions for hearing impaired he has lead the work with the IEC standard to its current standing.
