The company produced a range of products that were associated with FM broadcast radio transmission.

During the 1990s the company produced audio limiting and stereo encoding products at a time when commercial broadcasters throughout the UK were needing to upgrade this type of equipment.

Towards the end of the brand's life, a range of audio interface products were manufactured.

This product line was sold to the Sonifex company in 2006 and marketed under the ProAVM brand.

The design of most of the products used sealed cases (no ventilation) and linear power supplies.

Products such as the exciters, audio failure detectors and radio links remain in regular use around the world, despite being 20–30 years old.

The highly regulated broadcast industry in the UK at that time meant that the market was not open to small companies.

In the years after the merger, it was the SBS brand that gradually disappeared as the products were replaced with new Eddystone versions.
