Auri™ TX2N Transmitter

Background

Ampetronic and Listening Technologies are world leaders in the design and development of assistive listening technologies that improve the quality of life for people who experience hearing loss. 

Auracast™ is a new Bluetooth feature that offers an incredible listening experience for both general and assistive applications. Auri is the first Auracast™ broadcast solution for assistive listening. The Auri™ TX2N Transmitter can transmit to an unlimited number of receivers.  It’s perfect for public spaces like tour systems, lecture halls, and conference centres. 

Optima have been collaborating with UK based Ampetronic for several years and were tasked with designing a new transmitter to be part of the suite of products in the Auri™ system. The brief was to create a sleek, modern looking unit that delivered both on functionality and ease of installation. 

Approach

The starting point for the project was to create multiple concept sketches, models and renderings that could be used as the foundation of the development of the unit. The chosen design was then developed, working with the Ampetronic electronics team to ensure the placement of the PCB and multiple interface ports were optimised. 

After development of the device in CAD, initial prototypes were produced to help perfect the design. As the product developed further, production standard prototypes were built for feedback and testing. The final prototype is also used to give a high degree of confidence prior to full scale manufacture. Throughout the development process we used DFMA (Design for Manufacture and Assembly) to optimise the design for moulding, ease of assembly and reduction of part count to reduce manufacturing costs without compromising the product.

Delivery

The final product is a sleek, low-profile transmitter resembling a WiFi access point that has a multi-functional mounting bracket that offers for ceiling or wall installation.

The product has already won multiple industry awards at ISE 2025, and is shortlisted for the 2025 Inavate Awards.

Impact

Ampetronic is renowned for delivering high-quality products, and the development of the Auri Transmitter had to meet those high standards. Our commitment to excellence required a design that seamlessly balanced functional simplicity with ease of installation, manufacturing efficiency, and a premium aesthetic.

Optima once again delivered outstanding results. Their expertise ensured the Auri Transmitter not only met but exceeded expectations—offering an elegant, intuitive, and highly manufacturable solution. The result is a product that is simple to install and use, while maintaining the high quality Ampetronic is known for.
