Trilogy Selected for Royal Opera House Backstage Upgrade

Gemini takes centre stage in a ground up communications overhaul

Trilogy Communications, the global provider of intercom systems and Master Reference Generators to the performing arts and broadcast industry, today announced that London’s iconic Royal Opera House has selected Trilogy’s latest Gemini intercom system to replace its existing communications infrastructure within the backstage and auditorium areas.

Trilogy will work in close partnership with the Royal Opera House to ensure that the system is tailored to meet its exacting needs. The installation will include a combination of standard, touch and custom engineered operator panels as well as alternate power supplies to allow operation on the Opera House’s existing DC electrical supply.

Gemini’s architecture is built on the concept of a de-centralised, scalable platform of 32 port matrices each with IP connectivity. The 20 kHz audio performance is preserved both internally and over a Gemini network of up to 256 ports using the proprietary High Speed Link (HSL) over standard Cat 5 or fibre connections. This approach eliminates the single point of failure, and combined with both the use of a dual redundant ring of audio and IP failsafe routing, ensures that Gemini delivers ultra resilient performance.


Gemini’s flexible design is suited to every application and using Gemini’s seamless IP interfacing, a network can be expanded almost limitlessly in terms of system size and geographic location via LAN, WAN or Satellite. Gemini’s IP credentials are further enhanced with its comprehensive bandwidth management capabilities capable of accommodating variable network conditions. 

Intuitive system operation allied to connectivity for both traditional and IP enabled intercom panels, together with support for telephony and intelligent interfacing to analogue and SIP enabled phone systems and portable devices, makes Gemini undoubtedly the most flexible system available today.

John Sparrow, Senior Sales Engineer at Trilogy, added: “This is a prestigious installation for Trilogy and we are delighted to be able to work alongside the Opera House staff to create a system that carries them forward into the future.”
