In the USA, ClearCom is commonly used.Īs many of the technical operators are tied to expensive pieces of equipment, headsets are often wired. "Electrics on cans", "Going off cans", "Quiet on cans!").Ī commonly used system in the UK is produced by Canford Audio under the TecPro brand. (eg "Your call for tomorrow nights show is 6.55pm")ģ) A request for an actor to come to the stage because an entrance is imminent (these are courtesy calls and should not be relied on by actors - eg "This is your call for the finale Mr Smith and Miss Jones")Ĥ) An acknowledgement of applause (eg Curtain Call)ĥ) The DSM on the book is said to be "calling the cues".Ħ) The Colour Call is a list of lighting gel required for the lighting rig.ħ) The Final Call is also known as The Half - 35 minutes before the performance starts, and the latest time when the cast and crew should be in the theatre.ġ) Headset earpiece, microphone and beltpack used for communication and co-ordination of technical departments during a performance.

A 'Company Call' means the full cast and crew are called for the rehearsal.Ģ) The period of time to which the above call refers. A rehearsal call for the next day / week used to be posted on a Call Sheet on the stage door noticeboard, but is now often an online document, updated by the stage management team. The term now refers to the digital equivalent - taking multiple audio tracks and mixing them together at their set levels onto a single (pair of) tracks.ġ) A notification of a working session (eg a Rehearsal Call, Band Call, Photo Call, Focus Call). It allowed many sounds to be recorded onto one tape. Describes the mixing down of multiple sounds from different tracks onto one track, hence freeing up the other tracks to be re-used. slowly.Ĥ) This facility was available on many multitrack tape machines. This can also apply to the fast blackout/lights up cues that happen at curtain calls. When taking curtain calls, the Stage Manager would instruct the head flyman 'On the Bounce Please' for all calls prior to the final call, which was always 'Hand over Hand', i.e. A bounce doesn't need to be seamless, whereas a cyclorama should be.ģ) Describes the fast in/out movement of 'bouncing' flown house tabs, traditionally used during curtain calls. Strictly, a bounce is a white or light blue cloth onto which light is bounced to backlight another cloth. Some control desks permit the use of absolute addresses, where the first address of the 2nd Universe, normally called 2/001, is numbered 513.ġ) Diffuse light that has been reflected from the stage, walls, cyclorama etc.Ģ) 'Bounce' is sometimes used for a flat (non-curved) cyclorama. By default, Universe 1 is used, so DMX address 120 on Universe 1 is known as 1/120. In larger systems, where more than 512 channels are required, each block of 512 addresses is called a Universe. The address is either set via pushbuttons (up / down) to get to the correct channel, via a menu screen, via small rotary selectors where you can set each digit of the address, or via DIP switches where each switch represents a binary digit which combine to give the full address.
Moving lights requiring 16 DMX channels each might be addressed to 120, 137, 154 etc. A moving light requires many DMX channels.įor example, in a situation where you have three 6-way dimmer racks, the first should be addressed to 1, the second to 7 and the third to 13. A dimmer rack requires 1 DMX channel per dimmer. (LIghting) Each item of equipment controlled by DMX512 has an address, which is the first DMX control channel to which it will respond.
