Sometimes, back of the envelope calculations do not tell the whole story and neither do simulations. This article is a follow-up to the original article Phantom Piezo Preamp and addresses some errors and misconceptions that have arisen.
The Phantom piezo preamp module (available here in the shop) has been very […]
Update: reStomp re-ampers available for sale in the shop.
Back in 2012, I wrote about re-amping and offered a design for a transformer-coupled interface between balanced-line output from a professional recording device and the unbalanced and lower-voltage input to a guitar amplifier. If you’re not familiar with re-amping, the idea is that […]
In the first part of this series, we introduced the idea of power control separate from the dimmer system and gave an overview of different ways we can manage switching of power to installed appliances. In this second part, we will look at remote-control schemas for independent contactors.
One Big Relay
So, the first option […]
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 […]
