- The ability to filter or hi-light selected parameters and fixtures.
• Two Sound to Light (STL) sources with selectable frequencies to activate stored lighting states.
• A Bass-Step-Chase facility for the triggered synchronisation of Chase steps with the regular
repetitive beat of an audio source.
• SVGA compatible output port for connection of colour monitor
• 3.5” PC compatible disk drive for storage of internally stored memories; to upgrade console software
and to add fixture templates to the fixture library.
Operation Requirements
Preset Mode
Preset mode shall be for the basic creation and setting up of all lighting looks in a typical two preset
operation. A basic lighting look shall be created by setting the required channel on one of the coloured
coded presets and setting the same coloured preset master. Other looks may be created in the same
manner on the opposite coloured preset. It shall be possible to invert the Yellow preset master to allow
a simultaneous manual crossfade from one preset master to the other Preset master, or between the
Yellow preset master and the Grab master.
Wide Mode
The Wide mode shall utilise both banks of faders as a single preset of 48 channels. The yellow faders
shall control the low channels and the red faders shall control the high channels. The yellow preset
master shall control the total output of this single wide preset. The use of the Grab Master in Wide
Mode shall enable the console to operate in a two preset 48 channel configuration.
Scene Mode
Scene mode shall primarily be for the replay of user programmed scenes and chases. In this mode, the
faders of the red bank shall become playback masters containing 9 pages of the various stored
memories. It shall be possible to concurrently run up to 24 scenes or chases on the red playbacks.
It shall be possible to playback a scene or chase on the Grab master and a stack on the Stack master,
regardless of the current mode of the console.
Flash/Assign Pushbuttons
Each pushbutton associated with the 48 preset faders and the 3 masters, shall be multipurpose and
provide, but not be limited to, the following functions:
• To ‘Flash’ or ‘Bump’ the contents of a particular fader.
• Provide an alphanumeric entry.
• Select various secondary functions.
Parameter Selector buttons
Each touch sensitive “virtual” buttons shall be used to select up to 24 associated parameters for
Intelligent fixture control and be backlit with a multicolour LED to indicate current status and function.
Parameter Scroll Bars
Each of the touch sensitive scroll bars shall be used to activate and control selected parameters for
Intelligent fixtures, by the use of a finger or suitable stylus. Changes to parameter values shall be by
either mousing, or tapping the area within each scroll bar. Each scroll bar shall be transparent and
have a LED display beneath, indicating the following:
• Name of the active parameter
• Positional values of the parameter in 8 bit or 16 bit resolution
• Wheel stop positions and relevant names of the positions as determined by the fixture template
• Movement times of the parameter
• Delay times of the parameter
Indicator LEDs
The Indicator LED on each pushbutton, associated with each preset fader or master, shall be
multipurpose and provide, but not be limited to, the following functions:
• Indicate valid key options during operation.
• Indicate that a timed fade is in progress by flashing slowly.
• Indicate contents of the playback masters during editing, selecting or programming
– Scene – “on”
– Chase – “double flash”
– Stack – “slow flash”.
• Indicate the level of its particular output with a brightness proportional to its equivalent numerical
System Design
The console system shall provide, but not be limited to, the following:
• Diagnostic routines to check the status of available memory, battery circuit status, switches, LEDs,
and the linear performance of faders and the rotary encoder.
• Individual In and Out fade times up to 999 seconds, to be programmable on every scene, or
controlled directly from the In and Out Time Faders.
• Provide a ‘Page-freeze’ function, to prevent the contents of any Red fader from being changed if its
fader is above a level of 5% when a different mode is selected, or the current page is changed.
• Yellow preset master operation is to be optional in that ‘Normal’ or ‘Inverted’ operation can be
selected in the console Preferences function.
• Softpatching to be fully proportional and allow the allocation of any or all 512 dimmers to any one
channel fader.
• LTP (Lastest Takes Precedence) control of Intelligent fixtures to be conducted on touch-sensitive
scroll bars and selector buttons, whilst HTP (Highest Takes Precedence) to be controlled by the
desks faders.
• Up to 500 steps to be programmed in any one stack, of which each step may be a scene, chase or
a Snapshot of the output. Delays and Autolinks can be programmed between any step.
• Up to 250 steps to be programmed in any one chase.
• The facility to copy playback information directly to any another memory location
• The facility to save data on to a 1.44MB disk via the disk drive option. The entire memory contents
of the console shall constitute one ‘Show’, and it shall be possible to save multiple shows onto one
• The facility to upgrade system software insitu via the disk drive. Systems requiring any tools or
removal of panels to upgrade software will not be acceptable.
• The use of PCMCIA cards or equivalent, for the purpose of saving or backing up internal memory or
show data, will not be acceptable.
