The RB-LC3 3 way power/light controller is a triple output switching unit for controlling external mains indicators, primarily studio status lights for broadcasting applications, such as On-Air, Mic-Live and Rehearsal/Live lights. It will be on display on stand number 8.561 at IBC2003. Each output can be individually controlled by one of three remote inputs (pulled high, or low), by a telephony input (when ringing, or off-hook or both), or a combination of two inputs (to control two outputs, e.g. for Rehearsal/Live situations).
Sonifex Sales Manager Eamonn Heffernan commented :” We’ve had a number of requests from our distributors for this kind of light controller for use in studios. The usual application is to control “on-air” lights inside and outside studio doorways. However, we’ve designed the RB-LC3 to be a little more versatile so that lights can be controlled from a combination of 2 signals, for example, for “rehearsal/live” switching, or even from a telephony input to show ringing. The unit is programmable, so if people have any special light switching requirements, we’ll probably be able to accommodate them.”
A pre-set potentiometer on the rear panel controls the flash rate of the output and neon indicators on each power socket show the status of the mains output. The three IEC outputs are controlled by zero-cross point drivers. When an output is activated, the A.C. voltage level at that output will be equal to the mains input voltage used to power the unit. External control of the switched mains outputs is via the 15 way D-type plug connector.
The telephone Line input and Handset output are via two RJ11-4 type connectors. The telephone connections are wired pin to pin from Line to Handset except when the remote Ring Mute control input is asserted. In this case the ring signal to the Handset is muted. The status of the telephone Line is continually monitored so that Handset ringing and off-hook conditions can be indicated.
The RB-LC3 is available now with a UK list price of £249.95
