Lemo UK supplies connectors for radio microphone systems that deliver high quality, transparent sound for TV and film productions Watching TV presenters race about while still presenting exciting television; or actors still being audible while performing action scenes is not just a testimony to the performers' skills, it is an engineering feat that demands high quality, reliable and transparent sound quality as critical factors in sound systems

Waterproof connector aids all-weather meter
The Castle Group has a weatherproof and dustproof range of sound level meters which use Lemo's rugged and weatherproof K Series connector.
High Wycombe-based Audio designs and manufactures radio microphone systems that have been heard but not seen in blockbuster films and TV projects.
These radio microphone receivers and transmitters are strapped to a performer, usually in the small of the back, so that transparent, ie pure, without modification, natural-sounding voice quality transmissions can be sent and received for TV and film production.
Lemo UK has supplied connectors to Audio for over a decade, satisfying requirements for successive generations of the company's radio microphone systems.

Connectors clean up for cardiac monitoring

Single-fibre connector is alternative to splicing
Innovative technology originally developed for the CERN European Organisation for Nuclear Research has been used in the manufacture of the first subminiature single-fibre-optic connector.
The company's 2c series multipole connector is used in Audio's RMS 2020, RK2 and RK4 racks.
The RMS 2020 radio microphone system equipment has to be small, compact and lightweight as well as totally reliable and secure.
If the connection should be broken resulting in lost sound, the cost could run into thousands of pounds in downtime for high budget projects.
Audio says that the choice of Lemo connectors for the RMS 2020 was based on the need for a high quality, lockable connector system, with good contact and an attractive finish.
In an image conscious industry, it is important that the product looks like what it is - a visibly sound piece of engineering.
Audio has recently developed the RK2 and RK4 racks, portable rack systems which are for use with the RMS 2020 radio microphone transmitter and receiver system.
Lemo UK supplied a 6-pin circular, nickel-plated brass body connector, the body of which includes a locking mechanism.
The connector interfaces are gold-plated brass pins for a high quality, reliable connection.
The design specification calls for a compact unit, engineering quality that does not allow introduction of noise and one whose look reassures the user of its quality.
The Lemo socket is particularly suited to the system's compact design as it protrudes a marginal 7mm inside the case.
The Lemo plug extends just 22mm when mated, for the lowest possible profile while maintaining quality integrity and it is essential that the microphone lead stays plugged into the transmitter and cannot become disconnected accidentally.
The plug is also engineered for minimal space usage, measuring just 14mm in diameter.
The RMS 2020 system 32-channel synthesised diversity receiver together with the transmitter and output cables all use Lemo connectors.
Supplied by Lemo UK, the ERY.2C.306.CLL has a locking mechanism that is essential for stressful film and TV environments, as a lost connection can result in costly retakes or production postponements.
"Lemo offers a high-quality locking capability", says Audio.
It cannot be unplugged without specific user action.
Transmitters can therefore be strapped to the most energetic presenter or actor's back and cannot be displaced.
To maintain a constant force on the male contact for a secure connection, the pressure spring is machined integrally with the contact.
This spring maintains a constant, even force on the male contact, when mated.
Quite simply, "The items offered by Lemo met our design requirements", says Audio.
