Forestage Elevators


A new system is planned for installation in August 2017. Details will be added here once confirmed.

Currently the original elevators cannot be moved from flat-floor auditorium position.

Note that this usually forms part of the auditorium seating area. Use of the forestage will reduce seating capacity, which must be agreed before tickets go on sale.

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; full-height flying is not possible.

6 no. Tuschler LiftIt PW BGV-C1 motorised winches, with ladder bar (11m width), 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.

  • Maximum-height out dead = 9.1m (visible height c. 5.7m)

Variable Acoustics

The theatre is equipped with various 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

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. 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.

Leg lengths

(Deck heights shown)

  • Size '1' – 12 no. legs, 190mm (only required where decks overlap)

  • 2 no. modular step unit, up to 3 treads (max height = 570mm) or can be combined for 6 treads (max height = 1140mm), with handrails. Can only be used in conjunction with a section of deck at the same height.


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. You may be required to demonstrate the effect on site before you are allowed to use it for the performance.

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

Colour gel, gobos and other consumables are not provided from stock, but can be supplied as a chargeable extra, by advance request.

House Lighting

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

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

ETC 'Sensor 3' dimmers, with:

  • 74 dual 3kW modules (148 channels)
  • 15 dual 3kW non-dim modules (30 channels)

Modules can be swapped around (in pairs of channels) to suit the lighting design. Additional modules may be available from the Middleton Studio, if not in use.

Control Desk

ETC Ion with 1,536 channels, 2 x 10 fader wing and touch-screen monitors. 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). We ask that visiting equipment is patched above this range.

The offline editor for our console can be downloaded from ETC. We are currently operating Version 2.4.1 (October 2016). We can provide a base patch file if required, or use our Standard Patch Sheet.

The control desk operates over Ethernet. If required, a portable DMX Input Node allows other control desks to connect to the dimmers and house lights (using 1 universe only). There is a special Patch Sheet for the DMX Node.


DMX outlets (5-pin XLR) are available around the theatre (see Facility Panel Layout), terminating at a patch rack 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 only.

3 no. 10-way DMX splitters are provided for outputs around the theatre, using Universes 5, 6 & 7 for moving/LED fixtures and additional equipment. Universe 7 is available for visiting equipment. If using our LED rig, it is preferable to use Universe 7 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 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). Far-upstage front light is not possible from the tension wire grid; better to use LX1 or the proscenium booms.

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 upstage fill light, 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.

Moving lights and other additional equipment can be rigged on the winch bars.

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).


Lighting Layout Plan

Detailed Facility Layout Plan

See next tab below for Standard Rig details.

Lantern Stock

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.

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 the pre-rig requires substantial changes to our standard rig.


These lanterns will cover most needs, but additional equipment is likely to be required for complex shows. 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.

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.

Semi-permanently installed:

  • 4 no. EM-Acoustics EMS-121X full-range loudspeakers, covering stalls & circle.
  • 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 additional front fill loudspeakers (see 'Additional Equipment') and use the Circle fill speakers as a vocal-only 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. In normal theatre mode, this operates with L & R + 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 (see Facility Panel Layout). An alternative system exists for self-powered loudspeakers, consisting of switched power outlets (PowerCon) on the Facility Panels. All switched power outlets (labelled as 'Switched AV Power') can be controlled from a single relay switch in 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.

The remote mix rack has 24 no. XLR inputs and 12 no. XLR outputs, and is usually located in the Dimmer Room (although can be situated on stage if required), linked to the console via Ethernet. A portable extension box is also available, giving 8 additional inputs and 4 outputs; - this is normally used with the 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 1.51 (May 2015). If required, we can provide a base file with our standard I/O arrangements.


A conventional audio patch is provided around the building (3-pin XLR):

  • 70 sends
  • 64 returns
  • 12 sends to Control Room
  • 6 returns from Control Room
  • 4 sends to Middleton Studio
  • 4 returns from Middleton Studio


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 - uses 3.5mm locking jack connector) - see important notes below.
  • 2 no. Sennheiser Handheld Vocal Microphones (for use with above system – only 8 channels available in total).

Additional microphones may be available by prior arrangement (see below).

We have a reasonable stock of XLR microphone cables.

Batteries and other consumables are not provided from stock, but can be supplied as a chargeable extra, by advance request.

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. The other 4 channels can be hired in, at cost. 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. Please enquire for further details.

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.
