LIGHTBOARD M SPECIFICATIONS
The system as described below is manufactured by Strand Lighting. The lighting’coritrol system
is microprocessor based, and specifically designed to control theatrical, television and motion
picture dimming systems.
I. BASIC CONSOLE DESCRIPTION
The control system is comprised of but not limited to, the following minimum requirements:
1. Cue storage - 200 cues for 96 control channels or 140 cues for 144 control
channels.
2. Dimmers - the system is be capable of driving up to 768 dimmers over multiplexed
control lines.
3. Memory Retention when disconnected from AC mains power input, the control
system RAM (Random Access Memory) retains all data for a minimum of three
days by use of a maintenance-free super capacitor.
4. Modularity - the system is modular based with the capability of user serviceability
and expansion. The system shall accept up to eight Manual Channel Modules and
one Submaster Module.
.5. Display - a colour monitor is provided as standard with the system to supply on
line display of channel levels, active cues and effects, and other status
information.
6. Special Effects - the system has two special effects generators which are capable
of either channel or memory chase, with programmed or manual step times.
7. Patch Tables - there are a minimum of four independent electronic proportional
patch tables.
;8. Backup - the system incorporates as standard a memory
backup which permits channels to be assigned to
submasters for control in the event if a central
processor fai lure.
Control signal is multiplexed with no more than four twisted pair of~ wires necessary for
a maximum of 384 dimmers. Systems requiring a separate control wire for each dimmer
are not be acceptable.
1
Control surfaces are textured dark brown finish with identification in ivory. Channel controllers
are colour coded to respective split crossfaders. The console is factory wired with receptacles for
the plug-in dimmer cables. A mains power cable and set Of 8 metre control cables are included.
II. STANDARD OPERATING FEATURES
The control console shall provide, but shall not be limited to, the following operating features:
1. It shall be possible to access all 96 or 144 channels (depending on software
configuration), regardless of the number of physical channel potentiometers
present on the console.
2. Each channel and submaster fader shall have an associated bump button which
may be disengaged, or operated as pile-on or solo, with a bump level control.
3. The A/B crossfader shall act as preset masters or as memory playback faders,
with recorded crossfade and split fade time values. Immediate manual over-ride
and time adjustment shall be possible.
4. The X playback fader shall have recorded crossfade, split fade, delay and wait
time values. It shall be possible to halt, reverse, resume and rate over-ride an
active cue.
5. Fade progress shall be indicated on the VDU display and on the 21 segment LED
bargraph associated with each playback fader.
6. It shall be possible to record blind by digital address in Cue Mode.
7. The console shall proVide a “link to cue” ability, allowing cues to be played back
out of numerical sequence.
8. The system shall have a minimum of eight field programmable “learn” sequences
that can be programmed to remotely activate any series of pushbutton actions,
each containing up to 32 keystrokes.
9. There shall be a minimum of 24 Submaster faders,
~. which may control any system memory. Systems containing 144 control channels
are limited to a
maximum of 24 submsters. Ninty-six channel systems may contain either 24 or
48 submasters.
2
io. Digital modification to memories which are active in the Submaster stores shall
be immediate.
11. It shall be possible to record any system memory as and effect memory for
playback on the effects faders.
12. For ease of operatiOfl~ the effects playback faders may be loaded ln advance.
The Stop/Start and master fader shall allow smooth entrance and exit from effects
memories. AlternativelY, with the effects faders reading at Full, Effects memories
may be cut live to the stage.
13. ModificatiOn to effects memories active in playback shall be immediate.
14. It shall be possible to clear the entire system memory or to selectively clear only
the cue store or patch tables.
15. Each of the four patch tables shall have the facility to electroniCally patch any
dimmer to any control channel, with proportional level assignments.
16. It shall be possible to access any dimmer directly, by-passing any channel
assignment.
III. BASIC CONT1~QkLEI{TS
The LIGHTBOARD M control console shall consist of but not be limited to the following
control elements:
A. Command Module (One required)
1. A Grand Master
2. A. Blackout switch
3. A three position Bump Select Switch, which assigns channel and submaster bump
action to On, Solo or
off.
4. A rotary Bump Level Control.
5. A command keypad for entry and modification of data.
6. An A/B split dipless crossfader for A/B presets or recorded memories, with
associated “assign” and “sequence” pushbuttons and tracking bargraph.
7. An X crossfader fro playback of memories with Go, Stop, Sequence pushbuttons
and dual tracking bar graph.
8~ Two Effects playback faders with associated
“assign” pushbuttons and Stop/Start buttons, each
with LED displays indicating Effect loaded and
effect running.
3
9. Four Fade rate adjustment controllers to manual adjust fade times from 0 to four
minutes on the A/B and X crossfaders.
10. Two fade rate adjustment controllers to adjust effect step rates from .1 to 3
seconds.
11. A three position keyswitch which shall select console operation of Off, Show and
Record.
12. Associated with the command module, there shall be an integral video driver for
local RGBI colour and remote composite video monitors as well as a worklight
control switch.
B. Channel Control (___ required)
Each channel module shall provide for independent manual control of dimmers assigned to the
channel faders. Each module shall include the following:
1. Twenty-four manual linear potentiometers arranged in 2 scenes of 12 channels
each. Each linear fader shall4 have no less than 58mm travel with associated scale
of 0 to 10 calibrated in half steps.
2. Twelve bump button, one per channel controller.
It shall be possible to connect up to eight channel modules to the system.
C. Submaster Module
The submaster module shall provide proportional overlapping and pile-on control of user
selected memories. The module shall contain:
1. Twenty four submaster faders, each with no less than 58mm travel and an
associated scale of 0 to 10 calibrated in half steps.
2. Twenty four bump buttons, one per submaster fader.
D. Library Module (optional)
Addition of this module shall provide the following operational features:
1. 1 - 3-1/2” floppy disc drive for memory storage. The system shall facilitate the use
of
commercially available discs, with initial disc
formatting provided as a console function.
2. 1 - RS232 printer interface and receptacle on the rear of the module.
3. 1 - Designer’s Remote Focus Module Receptacle.
