Studio Illuminated Signs
SignalLED Range of RGB LED Signs For Studios

The SignalLED range of illuminated RGB LED signs are a new range of signs designed for outside recording, on-air & production studios, meeting rooms, conference rooms and for fixed installations. The sign itself contains the control electronics, and RGB LEDs are used, so the signs can be simply configured onsite for your particular requirements.

RGB LEDs - Any Colours Possible
The illuminating LEDs in the unit are RGB meaning that the colour of the sign can be selected on installation. You can configure the sign from one of 8 colours: white, green, red, blue, yellow, orange, cyan and magenta. The images on the following pages show the default colour of each sign.
Dual Control Inputs
The sign can be controlled by either, or both, of 2 pull-low inputs, e.g. a single input can be used to control a single ‘MIC LIVE’ sign, or 2 inputs can be used to control a twin ‘TX’ and ‘REH’ sign with independent control of each side of the sign.
Different Display Modes
Four modes of illumination are available:
Single or Twin Signs
Each sign is 40cm or 20cm long. The 40cm signs can be split into two 20cm sides which can be separately, or jointly controlled, e.g. you can have a 40cm ‘ON AIR’ sign, or twin 2 x 20cm signs, such as ‘ON AIR’ and ‘MIC LIVE’.
Flush or End Mounting
The sign is supplied as standard so that it can be mounted flush to a wall, e.g. for the ‘TX’ & ‘REH’ sign shown. However, a mounting kit is available, LD-KE1, to mount the sign perpendicular to a wall, e.g. above a door, such as the ON AIR sign shown.
Single 20cm Flush Mounting Sign
These are the available choices for the smaller 20cm flush-mounting signs. Custom signs can be made to order, if required.
Custom Signs
Although a range of standard signs is supported, custom signs, for example with your company name or logo, can be produced for a nominal setup fee. Contact Sonifex with your requirements.
How to Order
Just select the name of the sign from the list below.
Simple Installation
The signs are supplied with a 6V wall-wart power supply with international adapters for the UK, Europe, USA and Australasia & a 5m lead. Simply wire up your control signal(s) and DC input to the ‘screw terminal block’ inside the sign, route the cables through the integral cable clamp and mount the unit on the wall.
An installation tool, the LD-IT can be used to hold the sign in place on the wall mount whilst you wire it up. The display mode and colour options are set-up using an 8 way DIPswitch, accessible during installation.
