Stage Electrical Projects
Professional Theatres -
Electrical Distribution, Auditorium House Lighting, Front of house lighting and power, Stage lighting, sound systems
We have been involved in the refurbishment of Theatres lighting , sound and power systems.
A new stage lighting system has been installed with internally wired lighting bars set as a formal stage arrangement and with flexibility for in
the round performances. 72 channels of Stage dimming , 12 circuits dmx out control, and a separate House lighting system have given the
Theatre a flexibility of use.
Low level facility panels stage right and left with intercom, mic, returns, dmx control, dmx out, dimmer sockets /non dimmed sockets
enhance this flexibility.
Audio System wiring has been installed for f.o.h. paging, back stage paging, intercom, show relay, induction loop, public speaker system,
cctv, bar bells, Stage speakers with six positions of use.
A new lighting and power distribution system has been installed covering all areas of the refurbished Theatre including a new kitchen, bar
area, and underground performance space.
In the Main Hall we designed a sound system for Stage performance and for future visual representation,
A fixed sound rack was installed in the control room with radio mics, cd-cd, cd-mp3, cd-cassette, mini disc player.
A 32 channel mixing sound desk with on board effects was used to give control and effects on one board.
The speaker system included 3 no 250w stereo amplifiers, 31 band dual eq. a sound processor, and 6 professional speakers.
With the sound set up through the processor a balanced system was achieved with memory for small stage performance ( two speakers ) full
stage performance ( four speakers ) Cinema show ( six speakers )
A multi way facility panel was installed from the control room to stage right for intercom, mics. returns floor speakers in a mix of xlr,
speakon. mono and stereo jacks.
Wired vocal mics were supplied with low level boom stands for dance and performance on a stage platform.
The lighting choice for this venue was 4 cyc lights, fresnels, PC, Zoom Profiles,
2 Followspots on stands were supplied with local dimmer unit
A wall mounted source rack populated with a 150w stereo amplifier, cd-cassette player, rack mounted mixer.
This system was mixed into speakers on stands with 4 no. input positions for flexibility of use.
Lighting for this space was fresnels, PC, Zoom profiles
Council Town Hall
Portable Conference System - Council Meetings
A conference system was supplied for the council meetings to allow for each speaker no matter how quietly they speak , to be heard across
the room by other delegates and an audience.
This was a sound reinforcement system
This consisted of 9 desk mics and 1 no chairmans position. Each mic had a long goose neck stem for ease of use.
In a normal situation one mic between two is sufficient for most meetings.
A link cable was supplied for relaying the meeting to the audience gallery through the sound system
All of the equipment was supplied in an aluminium case for portable use at other venues.
Led stage lighting and sound
In the Main Hall we installed 4 no full range speakers wired back to a portable sound rack. The rack was populated with a hdmi laptop,
vertical 12 channel mixer amp, two rdio mic transceivers - 1 hand held, 1 lapel, 32 band eq, 250w amplifier
For the lighting system we installed a lighting bar populated with 8 no rgbw ( red,green,blue,white and mixed colours ) led lanterns controlled
by an easy to use 8 channel led desk. This led system allows for simple colour control without the need to install colour gels in the lanterns -
ideal for a primary school
We designed an audio system to give individual sound control of 3 separate rooms and when the dividing walls were retracted for one large
The presentation system was a 3500 lumens projector with a 3 mtrs electric screen. The video input panel allowed for bnc, vga hdmi .
The presentation system audio was incorporated into a fixed sound rack which allowed for a stereo output to either 1 large room or 3 small
We also allowed for an audio- video link from the control rack to a portable video conference system
We have designed and installed a led lighting digital dimming system in the Auditorium. The light fittings were 1200 x 300 arranged at high
level across the auditorium. These 46w led light fittings give off an even diffused light with no visible led lamps.
The dimming system was controlled from two positions on a programmed five button control plate. Programmed levels on buttons 1-3 with
button four turning off the lighting row in front of the projector screen to stop reflections.
This energy efficient system is maintenance free, cost effective, and runs cool.
School Drama Studio
We have designed an installation to give the best possible use of the performance space and the budget.
The stage Lanterns supplied - Fresnels, Pc's, Parcans, Profiles will allow for a very flexible approach to drama pieces.
To add to this flexible theme we have included a portable T-Bar stand and a bolt-on 3 channel dimmer - with two Fresnels and a floor parcan
controlled from this point.
We have populated a Portable flight cased sound rack with a Professional CD Player, and as specified a Professional Twin Cassette player.
Lavalier and hand held radio mics were installed for sound re-enforcement and give the student freedom of movement in the studio.
All the source equipment is powered by a 200w stereo amplifier with twin cooling fans and is mixed down through a 12channel Allen Heath sound desk.
Two speakers have been hung from the front stage lighting bars angled across the studio to give clear vocal representation.
Input panels for the speakers and lighting desk have been positioned on one wall to give a control area
Black ifr Dimout drapes have been added onto an existing track to give a more intimate feel for the performers and also use as a back drop.
The result is a small but professional studio ideal for performance and rehearsal.
We undertook to check out the Stage lighting system to locate faults - Lighting bars circuits were checked and re-terminated in their correct order.
The dimmer had channel problems which we located and replaced tri-acs as necessary- reprogrammed the dimmers and desk and commissioned.
The recording studio suite was not set up in any way or form that was usable.
We investigated, located all the problems with the equipment and cables. The cable problems were rectified and the equipment set up correctly.
A new system of use was set up through the mixing desk, digital recorder, sound sources, voices, eq and cd with pc recording also included.
