In my introduction to theatrical lighting systems I considered the many and varied lighting installations you might find in a performance venue and talked about independent power control which we will discuss further here.
In days gone by, practically all of the performance luminaires in a theatrical installation would use filament lamps and be […]
There are many different aspects of lighting in a public space – so many in fact that even seasoned technical crew can be confused. This article offers and introduction to the different lighting systems you might find in a performance environment.
Consider a traditional small theatrical venue. The venue has public spaces and non-public spaces. […]
Part 3 of this series introduced two professional cue light systems both using a three-wire system with an XLR grounded cable shield. One system is relay-based and the other microcontroller-based. Either system would be suitable for a professional installation. However, the two systems use different arrangements for the outstation. In fact there is […]
In part 1 we introduced cue light systems and discussed simple 2-wire a.c. systems. In part 2, we introduced d.c. switching and moved on to latching STANDBY. Later in part 2 we introduced a microcontroller-based design.
In this part we will consider adding MASTER GO to relay systems and then expand […]
In the first part, we covered an introduction to cue lights are and how they are used. We also looked at a simple two-wire system. In this part we are going to look at three-wire systems with automatic flashing.
Note that the circuits presented here are not complete designs and there are many […]
Some years ago I designed a theatrical cue-light system and I recently came across the drawings. The system was based on relays and I thought it would be interesting to see how cue-light designs have progressed over the years. I found that there are many different ways of doing cue lights and I thought I […]
The short answers is yes, absolutely – the Phantom Piezo Preamp has balanced input and output and effectively you connect […]
I had an enquiry about using LED’s to protect the input of the Phantom Piezo Preamp (available to buy here) which puzzled me slightly, as I didn’t initially see the point. However it was noted that if a piezo transducer is dropped onto a hard surface, the […]
