Trilogy’s pioneering Gemini ‘Distributed Matrix’ Intercom addresses the demanding needs of today’s broadcast and professional media industries for an expandable structure to cope as requirements change, a wide choice of operator panels to suit both application and user, simple installation over any distance and absolute reliability. In meeting these needs, Gemini provides a unique intercom solution that also combines a programme quality audio network with IP connectivity.

Gemini’s architecture is built on the concept of a de-centralised, scalable matrix platform with the significant advantages of IP capability, to deliver real time, high quality voice solutions across local or global networks. Combining intuitive user panel operation for IP-enabled, as well as traditional panels, Gemini is undoubtedly the most flexible intercom system available today.

Gemini’s unique design is suited to any Broadcast application ranging from a single studio to the largest media complex. By using Gemini’s seamless IP interface, the intercom network can be expanded almost limitlessly both in terms of system size and geographic location via LAN, WAN or Satellite.

A single Gemini matrix accommodates up to 32 ports, each freely assignable for use with control panels or 4 wires, whilst the IP gateway adds provision to stream bi-directional audio traffic over a further 32 IP channels.

A Gemini matrix frame supports up to 4 interface / expansion boards, each handling 8 ports of audio and / or data in various signal formats to suit installation requirements. These option boards are hot-pluggable and may be used in any combination.

The audio expansion board is used for connection of control panels over Cat 5 / 6 cabling and for 4 wire audio connections to other devices, including wired and wireless beltpacks , In Ear Monitoring systems, CCUs and audio consoles.

Where interconnection of control panels over a network is desired, an IP interface board supports up to 8 IP enabled panels via any conventional LAN infrastructure.
