Power On/Power Off
It is inadvisable to turn the desk off
immediately after programming a
memory. Turning off the power
immediately after pressing the
PROGRAM button may cause some of
the data to be lost. Instead, wait a few
seconds, then turn off the mains
switch. The desk should not be
re-powered for at least 20 seconds.
This ensures a complete reboot of the
system.
After it is switched on, there is a short
delay before the desk is fully
operational. Once ready, the ‘Please
Wait’ warning disappears from the
Memory Display, and the monitor
shows the screen appropriate to the
mode indicated by the Key Switch.
Mains Switch
The mains switch is located on the rear
panel, adjacent to the Key Switch, just
above the connector for the litlite. The
switch was deliberately positioned
above the litlite connector so that a 90º
litlite will protect the desk from
accidentally being turned off, which
could happen when trying to eject the
floppy disk.
Key Switch
To enhance the security of the memory
data in the desk, the Key Switch key
can only be removed in PRESETS
ONLY and RUN mode, thus enabling
the operator to leave the desk knowing
that no-one can change the memories.
Wide Mode
The desk can be used in WIDE mode
which turns the Sirius 500 into a single
preset 96 channel desk, and the Sirius
250 into a single preset 48 channel
desk, with channel flash buttons, .
Selection of either WIDE or TWO
PRESET operation is made in
PROGRAM mode, Set-Up: Desk
Set-Up.
In TWO PRESET mode the Sirius 500
has 48 Brightness channels (24 on the
Sirius 250) and can control 48 (24)
multichannel fixtures.
In WIDE mode the desk has 96
Brightness channels (48 on the Sirius
250), of which up to 48 (24 on the
Sirius 250) may be allocated to
multichannel fixtures, and the
remaining 48 (24 on the Sirius 250)
to simple, single channel ‘generic’
fixtures.
If WIDE mode is selected, turning the
Key Switch to PRESETS ONLY
temporarily overrides the desk set-up
and the desk returns to TWO PRESET
operation.
For more details please see the
references to WIDE mode in the
chapters on Setting Up the Desk (see
pages 5-6).
Connecting Up the Desk
Ensure that all external connections
are made to the desk before turning
the desk on. Failure to do so may
result in the mouse, external keyboard
or monitor not operating correctly. If
this occurs, turn the desk off, wait
20 seconds and turn the desk on again.
DBO
Pressing the DEAD BLACK OUT
button instantly takes all Brightness
outputs to zero, without affecting any
other outputs. Therefore all mirrors, gel
strings, wheels, etc., do not return to
zero or home positions when the DBO
button is pressed.
