Studio Illuminated Sign / On-Air light fitting

These classic studio signs are used extensively throughout the UK and are regarded by many as the industry standard studio warning light. They are regularly seen at most radio, TV and recording studios and provide a clear warning to those around thanks to their distinctive 'wrap around' design. They are particularly suitable for use in corridors as the unit provides a wide viewing angle when illuminated.

The units are supplied with a tough translucent polycarbonate cover which snaps over the base and does not require any special tools for removal. As standard, we provide red covers printed with the 'On-Air' or 'Recording' legend. (Please specify when ordering).

There are two base types available - Type A is most suitable for recording studios and meeting / interview rooms. Type B is designed for direct connection to a mixing desk's microphone channels and are common in radio studio environments. Outwardly they are identical in appearance; Your choice depends on how the light is to be used and controlled. See below for further details.

Both types are designed for permanent installation and require a mains power supply. Fitting instructions are included, however you should contact a professional electrician or suitably qualified person should you be in any doubt as how to connect this product.

Type A. This type has no low-voltage switching circuitry and typically is controlled using a standard mains light switch. This type would be suitable in recording studios, interview and meeting rooms, where you wish to provide a visual warning to those around you that the room is in use. It can be connected to the mains supply in the same way as a domestic light fitting controlled by a wall switch. Type A units should not be connected directly to studio mixing desks or other low-voltage control circuits without the use of additional Opto-isolated control units.

If you are happy to manually switch the light on and off using a wall switch then choose Type A.

Type B Type B units have an integrated mains switching facility meaning that they can be controlled directly from a mixing desk or other low voltage control source. Using this type is the easiest way to provide a warning to others that a microphone may be 'live' for example and can be connected to the closing contacts on a mixing desk microphone channel. Simply connect a low voltage cable between the closing contacts on your mixing desk and the low voltage contacts on the light fitting. Shorting Pins 1 and 2, will turn the light on. Shorting Pins 1 and 3 will flash the light at the rate set by the internal jumpers. Type B units still require a mains power source, however the integrated opto-coupled zero crossing mains switch module enables the unit to be controlled directly by low voltage sources.

Type B units are designed to be connected to mixing desks allowing the sign to illuminate when a microphone channel is opened for example
