1:1 Loops

Contacta’s Portable InfoLoop (PIL) and counter SupaLoop kits are a hearing loop solution for a multitude of situations where one-to-one communication takes place. These systems can be used in settings such as banks, reception desks, pharmacies, retail check-out counters, libraries, information booths, and one-on-one meetings.

The PIL is a mobile desktop induction loop system that incorporates an internal microphone, amplifier, hearing loop antenna, and rechargeable battery system. With the portable PIL, you can converse with others at home, in work meetings, in coffee shops, or at doctor’s office. For best sound quality, an external microphone is recommended.

Contacta offers a range of counter SupaLoop kits to uniquely fit every situation. To build your kit, choose between three microphone models, an under- or over-the-counter loop antenna, and pair it with the HLD2 Hearing Loop Driver. Over-the-counter antennas can be attached to a stand on the desk, mounted on a hard, vertical surface, or to a glass window/partition. The counter induction loop systems are designed to remain ‘ON’ continuously, so the user does not need to request assistance. Once inside the electromagnetic field of the loop, the user is automatically available to enjoy the technology by switching their hearing assist device to the telecoil (or T-Coil) Program.

Our goal is for users to be confident in their ability to hear within their community spaces and to utilize induction loops with ease and dignity.

The V-Series in the newest driver range, consisting of the V7 and V12a. Both drivers have a Class-D output stage and an audio subsystem build around an advanced Digital Signal Processing (DSP) core. The V7 is a perimeter driver and the V12 has a dual output with integral phase shifter for phased array configurations. The V-Series drivers are suitable for small to mid-size venues such as classrooms and conference spaces.

The HLD professional series driver range consists of the HLD5, HLD7 and HLD9. All drivers have flexible configurations able to accommodate perimeter and phased array loop designs. The drivers have a range of output characteristics suitable for mid-to-large-size venues such as lecture halls, conference facilities, performing arts centers, theaters, places of worship, sports stadiums, and airports.

Speech Transfer Systems

Speech Transfer Systems (STS) provides clear communication where normal speech is impaired by use of glass, security screen, or other similar barriers. Our STS window intercom kits come in a variety of microphone and speaker options to fit an array of counter configurations. All STS kits include the STS-A31 Hearing Loop Driver, choice of staff microphone and speaker, choice of customer microphone and speaker, along with an induction loop system.

The STS kits are available in Grey, Black, and Stainless Steel. For staff working in loud environments, a Breakout Box (B.O.B) is an accessory which allows the kits to be used with a headset as a replacement to the staff microphone and speaker, or as an additional option.

Speech Transfer Systems are suitable for any window intercom situation where one-to-one communication takes place through glass at a counter, booth, or desk such as banks, embassies, ticket offices, information centers, theaters, corrections facilities, and public transit systems.

Infrared Systems

Contacta’s infrared listening devices are ideal when a sound source needs to be transmitted to multiple receivers, when ambient noise interferes with comprehension, or when confidentiality is required within a confined space.

An audio source is converted to infrared light and projected to users via an infrared transmitter. Infrared receivers then convert the light back into audio, providing users with a simple and clear listening experience.

Infrared systems are ideal for settings such as courtrooms, medical facilities, police offices, and anywhere where confidentiality is important.

Contacta’s infrared systems are compatible with induction neck loops, under-the-chin receiving headphones, and standard headphones with a 3.5mm input.


Radio Frequency Systems

Contacta’s RF systems are ideal when sound sources need to be wirelessly transmitted across large areas, sending signals through walls regardless of floor plans. A FM transmitter is connected to an audio source such as a guidance recording or microphone which sends signals to the portable FM receiver.

These systems can utilize 40 channels simultaneously and provide a range of up to 984 feet. FM receivers can also be equipped with induction neck loops to aid inclusivity and accessibility, enabling users to listen using a hearing device equipped with a telecoil (or T-coil).

With a variety of FM transmitter and charging options available, Contacta offers solutions to fit your needs. Contacta’s radio frequency listening devices are designed for tour guides, theaters, auditoriums, conference rooms, house of worship, and classrooms.

Product FAQ

What is a hearing loop (or an induction loop) and how does it work?

A hearing loop (also referred to as an induction loop) is an assistive listening device that improves communication by enabling the hearing-impaired user to hear the sound source directly, therefore reducing background noise. Users can utilize a hearing loop (or induction loop) system through a hearing assist device such as a telecoil hearing aid, cochlear implant, or loop listener.

Sound and/or speech is converted into an electromagnetic signal by a hearing loop amplifier. The electromagnetic signal is transmitted via the hearing loop copper wire or antenna. Users inside the hearing loop copper wire or within proximity of the antenna picks up the electromagnetic signal through the t-coil program in their assistive listening device. The sound and/or speech is transmitted directly into the user’s ear, which significantly reduces the effects of background noise.

How much does a home hearing loop system cost?

The Contacta HLD3 Hearing Loop Driver is recommended for home loop installations. The HLD3 kits are sold with a room loop wire or a Loop Pad and range in price from $249—$289 USD (not including installation).

How much does a large area hearing loop system cost?

Every hearing loop installation is unique. There are several factors that go into the installation such as the construction material of the venue, how the hearing loop will be used, and where it will be installed. Contacta Dealers are trained to perform field tests where data like background noise is collected. They use the data to design the hearing loops and develop a plan of product installation. All these factors will give the Dealer the information necessary to provide a cost estimate.
