Forestage Elevators

The forestage consists of 28 sections of RAT SpeedDeck rostra, which can be re-configured to hall height, stage height, stepped down for seating, or removed completely for a shallow pit.

Unless otherwise agreed in advance, the forestage will be configured in stepped seating format for all lettings. Use of the forestage for anything other than seating will reduce the seating capacity, which must be agreed before tickets go on sale.

Although we have used it occasionally as such, the pit is not ideal for use as an orchestra pit.

The deck surface is painted matt black to match the stage (not as pictured above). The decks must not be painted directly, but can be covered with painted panels.

Pit Dimensions

  • 12.8m x 3.6m, consisting of panels 2m x 0.9m and 1.3m x 0.9m.
  • Legs provided to step down each row in 0.1m increments.
  • Legs provided for up to 7 decks to be raised to stage height.
  • Other configurations will need custom legs.
  • Max. pit depth (from auditorium level) = 0.8m with all decks removed.

Flying & Over-stage

There is a system of bridge walkways above the stage, which allow easy and safe access to the lighting positions and flying equipment. There are four bridges across the stage, with three 'flying slots' in between, which are the full width of the stage. The systems are primarily designed for suspension and ease of rigging; full-height flying is not possible.

6 no. Tuschler LiftIt PW BGV-C1 motorised winches with ladder bar, SWL 450kg.

Plug-in control pendant – either SR tech gallery or DSR. Only 1 hoist can be operated at a time; fixed speed.

N.B. Whilst these hoists are relatively fast and quiet, they are not designed for operation during a performance (although it can be done with suitable covering action/music).

Use of the winches must be considered carefully in conjunction with the requirements for lighting and masking.

  • Bar length = 11m
  • Maximum-height out dead = 9.1m (visible height c. 5.7m)
  • Minimum-height in dead = 1m

3 no. manually-operated 'hemp' bars (11m), SWL 100kg, tied-off on SR tech gallery. Normally reserved for border cloths.

Tabs & Masking

There are no house tabs (and no track for these).

  • Black tabs: 1 set (6m drop) on demountable track to suspend from a winch bar. Hand-pulled from SL.
  • Side masking: 8 no. 2m black legs, running US/DS in a permanent track at either side of the stage.
  • Additional legs: 4 no. 1.5m blacks, to be hung as required, 6.75m H.

There is a perimeter track running either side of the stage and across the back wall (under Bridge 4). Track height = c. 5.5m.

3 no. black border cloths to suit the stage.

1 no. white cyclorama cloth, 5.5m drop x 12m width (usually on the rear perimeter track).

Variable Acoustics

The theatre is equipped with facilities to vary the acoustic environment for theatrical performances or music. In concert format, the border and leg cloths must be removed to expose acoustic reflection panels, and special curtains are opened at the sides of the auditorium at high-level.

Stage Deck / Rostra

Stage Deck

29 no.* Lite-Deck heavy-duty rostra units, 2m x 0.8m (n.b. non-standard size).

These deck panels can be used to create multi-level stage platforms and walkways. They are not suitable for forming ramps or other irregular shapes. Each deck section requires 4 legs and must be locked together with adjacent decks when used at the same height. Decks at different heights can be secured together with straps or clamps. Decks can overlap with the use of shorter legs. Decks are usually painted black, but can be painted as required, as long as they are re-painted black at the end of the hire. Screw fixing is permitted.

The stage deck must be carried/assembled/dismantled by strong able persons with an appropriate risk assessment and the use of appropriate PPE. An additional charge will be levied if you require our technicians to set-up/strike the deck for your event.

* n.b. During the summer (July/August) at least 12 units of deck are unavailable due to other events taking place at The Leys. Please enquire for availability.

These are not compatible or interchangeable with the SpeedDeck used for the forestage.

Leg lengths

(Deck heights shown)

  • Size '1' – 12 no. legs, 190mm (only required where decks overlap)
  • Size '2' – 40 no. legs, 380mm
  • Size '3' – 80 no. legs, 570mm
  • Size '4' – 24 no. legs, 760mm

Litedeck recommend the use of additional bracing/fixing for heights above 1m.

We also have various timber treads, built to suit some of these heights.


Lighting Layout

House Lights Patch Sheet

DMX Patch Sheet

Please note: The use of special effects such as naked flames, pyrotechnics, firearms, strobes, lasers or certain types of fog machine is at the sole discretion of the Theatre Manager. Please advise us as soon as possible if intending to use any effects.

If hiring additional lanterns, please note that Great Hall uses 16-Amp outlets only.

Colour gel, gobos and other consumables are not provided.

House Lighting

GDS ArcSystem

Fully dimmable multi-channel LED system, controlled from master panel DSL or control room, or from lighting desk. 'Show Mode' disables white lighting and operates blue safety lighting in the wings, technical galleries, lobbies, backstage and control room.

Theatrical Lighting

240 circuits around the theatre, with 16-Amp socket outlets and/or Socapex 6-way outlets. See Lighting Layout for arrangement of IWBs.

ETC 'Sensor 3' dimmers, with:

  • 76 dual 3kW modules (152 channels)
  • 17 dual 3kW Non-Dim relay modules (34 channels)

Modules can be swapped around (in pairs of channels) to suit the lighting design.

Control Desk

ETC Ion with 1,536 channels, 2 x 10 fader wing and touch-screen monitors. Unless otherwise configured, the dimmers are soft-patched to channels 1 – 240 and the house lights to channels 1001 – 1024. Our LED 'Standard Rig' is patched to channels 241 - 330 (see next tab for Lantern Stock).

The offline editor for our console can be downloaded from ETC. We are currently operating Version 2.6.4 (February 2018). Please refer to our House Lights Patch Sheet and DMX Patch Sheet when creating your show file. We prefer not to re-address any of our fixtures if possible.

The control desk operates over Ethernet.

Using your own Control Desk

If required, a portable DMX Input Node allows another control desk to connect to our dimmers and house lights (via a single universe). There is a special Patch Sheet for the DMX Node.

Your desk must be capable of at least 2 universe outputs (1 to connect to our dimmers and house lights via the Node & 1 to connect to our LED equipment in the rig). A third universe will be required for any of your own fixtures. Note that it is difficult to patch DMX from the Control Room to the rig, so please discuss this in advance.


DMX outlets (5-pin XLR) are available around the theatre, terminating at a patch panel in the Dimmer Room. The lighting system operates via ETC Net 3, which can also be patched around the theatre.

The dimmers use DMX Universe 1 exclusively. The house-light system uses Universe 3 (soft-patched to the lighting desk). Universes 2 and 4 are assigned to the Middleton Studio and cannot be used.

3 no. 10-way DMX splitters are provided for outputs around the theatre, using Universes 5, 6 & 7. If using our LED rig, it is preferable to use Universes 7 and 8 for any of your own equipment to avoid having to re-address our LED stock.

8Theatre patch panel - spare.

Hot Power

Most Facility Panels have twin 13A RCD outlets for Technical Power.

The non-dim Sensor modules can be used (in pairs of channels) at any outlet where controlled hot power is required. The Standard Rig includes sufficient provision for non-dim supplies to our LED lanterns.

It is also possible to use the AV Powercon outlets on some facility panels in order to supply low-powered LED lanterns only (where non-dim outlets are unavailable).

There are also additional temporary power outlets located around the theatre, including a 16A outlet at each follow-spot position.

Lighting Positions

See Lighting Layout for arrangement of IWBs and rigging positions.

As a busy multi-purpose venue, it is rare that the lanterns will be 'in store', so will usually require some re-rigging to suit your requirements. The Standard Rig (see next tab below) will provide general cover of the stage.

Front-of-house cover is fairly standard, either from the Tension Wire Grid or Technical Gallery side bars. There is also a bar on the front of the Circle, and two short bars at Stalls-level either side of the proscenium (slips). Upstage front light is not possible from the tension wire grid; better to use the side bars or LX1.

The bridge walkways over the stage are excellent for safe access, but can mean some compromises for lighting. Over-stage positions may be restricted, dependent on the requirements for flying and masking. If full masking is required, or lots of flying pieces, the LX positions are suitable only for steep top/back or side light, but usually a compromise is made with positioning of the borders and winch bars.

The vertical booms either side of the proscenium are useful for lighting upstage, as well as side / dance lighting. Back light can be achieved from all of the bars, but again requires co-ordination with the flying and masking arrangements. Generally, LX1, LX3 and LX5 are the bars we use most. LX2, LX4 and LX6 are mounted at a higher level (no upstage angle), so have limited use, except for specials and back light.

Maximum individual lantern weight on the over-stage fixed bars (LX1-LX6) is 15kg. Moving lights and other heavy equipment must be rigged on the winch bars.

We also have 4 tank traps for creating additional free-standing vertical booms.

Please enquire for further advice. A site visit is recommended well in advance.

We have created a photographic guide to the various rigging positions for visiting lighting designers:


Over-stage Bar Heights

  • LX1, LX3 & LX5 - c. 6.3m from stage.
  • LX2, LX4 & LX6 - c. 6.75m from stage (n.b. no upstage angle due to position of bridge).

Detailed Facility Layout

See next tab below for Standard Rig details.

Lantern Stock & Standard Rig

Standard Rig

Unless otherwise agreed, the Standard Rig will be supplied for all lettings. For concerts and other smaller events, this will provide sufficient general stage coverage with some basic atmosphere.

Our Standard Rig consists solely of LED fixtures for maximum efficiency and flexibility. The rig can easily be supplemented with our conventional lanterns from the list below, or with additional hired equipment. Hirers are welcome to make changes to the rig as required.

For larger shows, we can usually pre-rig to your design, if plans are provided sufficiently in advance. This is not always possible, depending on the schedule of other events. Additional charges may apply if out-of-hours working is required, or if substantial changes are required to our standard rig.

Standard Rig Plan


These lanterns will cover most needs, but we do not provide any moving lights. Hirers will need to make their own arrangements for providing additional equipment as required.

  • N.B. If hiring additional lanterns, please remember that Great Hall uses 16-Amp outlets, not 15-Amp.

Note 5 - 6 no. 15° lens available. Lens can also be removed for 60° wash.

Lanterns marked as "shared with studio" are subject to availability. Please enquire in advance.

Follow Spots

There are two follow-spot positions at the rear of the auditorium at the technical level, with dedicated 16-Amp supply to each. Mounting brackets are installed to accept most lanterns, so separate stands or spigots are not required. Follow-spots are not provided.


n.b. 11 seats at the rear of the main stalls section are removable to allow for optional technical equipment (e.g. sound mixing console). This must be agreed before tickets go on sale.

Main P.A.

  • 4 no. EM-Acoustics EMS-121X full-range loudspeakers, covering stalls & circle (left / right).
  • 6 no. EM-Acoustics EMS-51 compact loudspeakers, for fill & delays.
  • 2 no. EM-Acoustics EMS-115C sub-bass loudspeakers.
  • 3 no. EM-Acoustics AQ-3 Quad Amplifiers (4 x 775W), installed in the Dimmer Room with loudspeaker patch.

This PA will be adequate for most theatrical needs, except for the loudest of music shows when additional sub-bass loudspeakers are recommended (not provided). Musicals may also require additional loudspeakers, depending on the design. We often install front-fill speakers and use the Circle rear-fill speakers as a vocal delay for extra clarity.

The mixing desk can be configured to suit multiple outputs as required. Please liaise with the Theatre Manager in advance.

The system is controlled by an Allen & Heath iDR-8 (no user access). In normal theatre mode, this provides L & R with sub-bass crossover. It is also possible to provide separate inputs as required, such as a mono sub-bass feed.

Loudspeaker outlets (Speakon) can be found on selected Facility Panels around the theatre. An alternative system exists for self-powered loudspeakers, consisting of switched power outlets (PowerCon) on the Facility Panels.

A conventional audio patch (3-pin XLR) is provided around the building, including 12 sends and 6 returns to/from the Control Room.

Most Facility Panels also have a dedicated twin 13A RCD outlet for Audio Visual power.

Mixing Desk

Allen & Heath GLD-80 digital mixer with remote mix rack, linked via Ethernet cable. 36 inputs / 20 outputs available as standard.

The remote mix rack has 24 no. XLR inputs and 12 no. XLR outputs, and is usually located in the Dimmer Room with the audio patch panel (can be situated on stage or elsewhere if required), linked to the console via the network patch.

A portable extension box is also used, giving 8 additional inputs and 4 outputs; - this is normally used with our 8-way radio mic rack. The console itself has 4 additional XLR inputs, 4 XLR outputs, 2 stereo phono inputs, 1 stereo phono output & a digital output.

The console is fitted with a M-DANTE card, offering an additional 64 I/O channels via a Dante network (e.g. a laptop with necessary licence - not provided by The Leys).

We will prepare the desk in a suitable base state for your requirements, but it's worth familiarising yourself with the layout using the offline editor. For complex shows, you will need to allocate time for setting-up and programming the desk as required.

The offline editor for our Allen & Heath GLD80 can be downloaded from Allen & Heath. We are currently operating Version 1.61 (February 2018).

n.b. If you wish to bring your own console, then you will need to consider how to connect it. We only support Cat5 patching. There are only 4 audio inputs/outputs at the central mix position in the auditorium. If analogue connections are required, then it is very likely that you will need to bring a suitable multicore snake.


It is likely that additional microphones will be required for complex shows, particularly musicals. Hirers will need to make their own arrangements for providing additional equipment as required.

  • 8 no. Sennheiser EW300-G3 Ch. 38 UHF radio mics (lavalier + beltpack) - SEE IMPORTANT NOTES BELOW.
  • 2 no. Sennheiser Handheld Vocal Microphones (for use with above system – only 8 channels available in total).

We have a reasonable stock of XLR microphone cables.

Batteries and other consumables are not provided.

Radio Mics - Important Information

We are licensed for the operation of up to 12 radio mics on Channel 38 (UHF) - but please note, we only have 8 receivers. If using additional radio mics, we strongly recommend either hiring Sennheiser EW300 units to ensure compatibility with our system, or use an entirely separate system to suit your needs.

Important: We have a Shared Frequency licence for 12 channels in Channel 38. It is not possible to operate more than 12 channels in this range without risk of interference. Additional licensed channels are available to purchase on a temporary basis from Ofcom.

Headsets: Unfortunately due to their fragile nature, we are not able to supply headsets for our radio mics. Beltpacks will be supplied with standard lavalier ('tie clip') microphones only. You may wish to purchase or hire your own headsets, in which case they must be of the type fitted with a 3.5mm locking jack connector to suit our Sennheiser packs. A suitable product is the Pulse MIC-3000LJ from CPC.

We don't have any spare beltpacks or mics available.

Stage Management

There is no permanent Stage Management console, but facilities can be provided in the appropriate location as required.

Technical Intercom

Tec-Pro 2-channel system; outlets around the theatre with both channels available at all locations. Uses 5-pin XLR connectors, but we also have 3-pin jumpers for single-channel beltpacks.

10 no. dual-channel belt packs with headsets.

Cue Lights

Some Facility Panels have outlets available for a cue-light system (4-pin XLR), terminating at a patch panel in the Dimmer Room. No hardware is available, but the infrastructure can be used for hired equipment.

Paging & Show Relay

The paging microphone allows separate front-of-house and back-of-house calls, which can be made from DSL, DSR or the Control Room. Another paging mic is located in the Box Office.

Back-of-house loudspeakers are fitted in all dressing rooms, green room, changing rooms, wardrobe, control room and drama classrooms.

Front-of-house loudspeakers are fitted in the main entrance, foyer reception room, Balgarnie's Café and Trumpington Gallery (circle foyer).

Paging & show relay is controlled by an Allen & Heath iDR-4.

The show relay microphones permanently use 2 no. audio inputs on Facility Panel TFP209.

A video camera facing the stage is semi-permanently installed on the Circle, which feeds TV monitors at key locations around backstage, via the BNC video patch. This uses 1 no. video input on Facility Panel TFP209.

Monitors are located at:

  • DSL
  • Technical Gallery SR
  • Backstage (Scene Dock)
  • Control Room
  • Theatre Office
  • Green Room
  • Drama Classrooms (in lobby)

Temporary monitors (not provided) can also be placed at DSR or any other Facility Panel with a spare video connection.

Induction Loop

The auditorium is fitted with an induction loop system for hard-of-hearing patrons. This operates automatically via the show relay system as described above.
