The ADC Theatre (Amateur Dramatic Club Theatre) is the main student theatre in Cambridge, a white and blue building near to Sidney Sussex College in the centre of town. Officially the building is owned by CUADC and held under trust, but is managed as a non-school institution of the University of Cambridge itself. The ADC usually hosts two shows each night during term time, a Mainshow at 7.45pm and a Lateshow at 11.00pm. The Larkum Studio and ADC Bar can also be used for performances.

Show Applications for student productions open about half-way through the previous term. Those who are successful are charged on a box office split system, with the theatre taking 37% (+VAT) of gross income and an additional 9% (+VAT) as ticket commission.

General Information

The majority of technical info about the ADC can be found on the theatre's website and it would be silly to duplicate it all here (since that would just mean that one place or the other would be likely to become out of date the next time there is a change). See and for more information than the quick-reference data provided below.

  • The proscenium arch is 6.67m wide and 3.8m high.
  • The maximum stage depth is 11.1m.
  • The fly tower is 12m high with a maximum flying height of 11.4m.
  • The underside of the counterweight and hemp galleries is 5440mm high.
  • The load-in doors are 762mm x 2045mm and are on the first floor.
  • The stage traps section is 3.55m x 1.03m in dimensions.
  • The auditorium seats a maximum of 228 (221 in standard configuration) and has disabled access.
  • The Larkum Studio seats a maximum of 40 and has disabled access.
  • The Bar seats a maximum of 50 (46 in standard configuration) and has disabled access.
  • There is eduroam Wi-Fi provided throughout the building.
  • There are two backstage dressing rooms:
    • Dressing Room 1 (DR1) which is used by the Mainshow
    • Dressing Room 2 (DR2) which is used by the Lateshow.

The access to stage from the dressing rooms is to stage left. Entrances can be made directly onto the main stage, or onto the forestage through a Juliet. Similar entrances can be made from Stage Right if a get-round is created behind the stage backdrop.

Load-in access is via a straight staircase from the theatre yard up to the stage left wing. You may also take a 90-degree left turn at the top in order to pass into the front row of the auditorium. Particularly large items of set can either be taken into the front row of the auditorium by a 90-degree left turn at the top of the get-in stairs, or can be be flown onto stage through the stage traps. Access should be checked carefully if large items of set are being used.

The ADC has a fly tower with counterweight & hemp systems for flown set and owns a wide selection of flying equipment and lifting accessories. There is a fully-equipped workshop for building set, which ADC Theatre and Corpus Playroom shows can use for free.

It is customary at the ADC to refer to stage left as prompt side (PS) and stage right as off/opposite prompt (OP).


Much of the theatre is restricted access for safety and security reasons. If you wish to gain access to more areas—to attend an audition, for example—go through the yard and knock on the door of the Management Office. You can activate your University Card (often called a CAMCard although this is a common misconception) for use on the theatre's codelocks by tapping it on a machine in the Management Office. If you don't have a University Card then the Theatre's Management can issue temporary access cards. If unsure, knock on doors loudly and ask someone who's around the theatre - they should be happy to help you out!

In addition to regular card access, you can sign out keys to more unusual parts of the building; speak to Management.

You can access the backstage area through a door written "Stage Door" in the yard.


Restricted access, and often hazardous. Consult management before entering a void.

The theatre contains an assortment of voids: these are rooms that are too small, oddly shaped, or hazardous to be called a room. They include:

Rake void

The space under the seating of the auditorium. It's high enough to stand in at the rear end, but too low even to crawl in by the front. It contains the step bins. Formerly—before the 2018 renovation—used as an informal instrument store, the area is now kept locked as it is the plenum of the air-conditioning system.

PS roof void

The space above the PS wing. As of late 2018, used to store trunking, confetti drops, and some lighting equipment. Accessed from half-way hemps. Mostly lacking a floor; walking on anything other than the proper areas might result in you crashing through the ceiling of the PS wing onto the floor below!

PS floor void

Below the PS wing, and accessed through a small trapdoor over which the Genie is sometimes parked. Mainly used to store spare carpet tiles for the Clubroom. There is an adjacent diagonally-slanted stage dip which contains the safety hand rails used when Trap flying.

OP quad roof void

Notoriously cramped and somewhat purposeless, it's mainly used for service access when carrying out maintenance.

Bar roof void

Above the bar, and accessed from the Sound Box. Used to store the Yamaha Rio racks, headphone amp racks, drum acoustic screen and auditorium sound desk table when not in use. Also home to various bits of speaker flying hardware and projector lenses. Do not step off the designated wooden floor!

Workshop compressor void

Above the workshop extractor cupboard, and accessed via the small padlocked door near the ceiling.

Safety curtain void

A small void formed adjacent to the brick wall between the scene dock and paint dock corridor when the safety curtain is wound out.

Management garden

A tiny triangular area that's located on the other side of the door in the room with the laminator. It serves no useful purpose but is the source of frequent jokes.


Inaccessible for mobility impaired persons.

These are believed to be among the oldest rooms in the theatre. Unfortunately they are accessible by ladder only.

The vault

Storage area underneath the Production Office that's accessed from a trapdoor in the Tech Office. Used by Management to store theatre maintenance spares.

The museum

A small dungeon-like area located just off the scene pit underneath the workshop floor. Used to store old parts of sets that are thought to be worth keeping. There is also a selection of (theoretically) fire-retardant fabrics that have been purchased by previous shows, a spiral staircase, staircase banister spindles, a sink with requisite plumbing, and more.

Room Booking

The Larkum Studio, bar, dressing rooms and stage area may be used for rehearsals or meetings dependent upon availability. There is an online booking diary at which can be used to check availability and book rooms for your show. This facility is only available for productions taking place at the ADC Theatre and you must be listed as an admin of your show on Camdram in order to use it.

Productions are allocated 12 hours per week for rehearsals. If you require extra time you should contact the Theatre's Production Manager.

Technical Details

A reminder that technical specifications can be found at


The ADC Theatre has over 200 lanterns of various description, being of both the LED and conventional tungsten type. Control for these is provided through an ETC Gio @5 console with an ETCnomad Puck running tracking backup. A two port ETC Net3 gateway is situated in the patchbay and provides two universes of DMX connectivity from the lighting control network. There are 114 permanently-installed dimmer circuits and 4 switch circuits which all terminate on a PowerCON patch panel in the patchbay, allowing them to be routed anywhere on or around stage. An additional 6 Strand Act 6 dimmer packs are available from the Technical Manager, making a total of 150 available channels using in-house equipment. Additional dimmers can be added using DMX or network-based control.


The main auditorium has a fixed FoH sound rig of paired D&B Ci90 Tops and C7 Sub-bass speakers, mounted either side of the proscenium arch. The mixing position is a control box at the rear of the auditorium, and control is given though a Yamaha CL3. Tie lines are installed to all areas of the stage and auditorium, as well as the Larkum Studio, the dressing rooms & green room, FoH areas and the bar. These terminate in a Bantam patch pannel in the sound control box. Amplifiers are located in the patchbay and can be patched to various Speakon outlets around the stage. The Theatre also owns a selection of microphones for instrument and vocal use, several DI boxes and a stage piano. There are 16 Sennheiser EW300 G3 Radio Microphone receivers (with 16 wireless beltpacks, and 2 handheld wireless mics).

Production Resources

The Theatre has a sundries store that keeps a stock of useful consumable items that can be purchased by productions. A full stock list and price list can be found on their website.

The ADC has four computers available for use by anyone putting on a show at the ADC Theatre. All have Adobe Photoshop and InDesign installed. A folder will be created for your show which you should use for storing all files related to your show. These files are accessible from any of the computers. Please do not store files anywhere else on the computers as they are liable to get deleted.

The Theatre has a photocopier that productions are welcome to use. You should have received a four-digit photocopier code, which will allow you to photocopy, print and scan documents as necessary. The printer can produce A5 and A4 booklets as well as A4 and A3 sheets. The user code tracks how many sheets have been printed and we will charge the cost through to the show settlement. We also have a large format printer that produces the A1 posters we use around our Front of House. Productions are welcome to make use of it if needed.

There is a laminator that can be used to laminate posters to be put up around town. It will laminate from anything up to A3. Cable ties for attaching posters to railings can be purchased from Sundries.

The Theatre has a credit account with a number of different companies, including timber merchants and print houses. You can order goods on account by getting an order number from us and inform one of the management team. The Theatre will then pay the company from which you have purchased and deduct the relevant amount from your settlement. Deliveries to the theatre should be made between 11am and 7pm any day.
