MANUAL OPERATION
With the Grand Master and the A Master set to full on and the B Master set to off, arrange the A sliders
(top bank) as you require. The collective positions of the faders is called a preset. As the sliders move, the
changes will be seen in the output LED's across the top of the desk and also in any lamps which are con-
nected to the outputs. Set up another preset using the B sliders (bottom bank).
As you reduce the level of the A Master, the levels of the channels called by the A sliders reduce. As you
increase the level of the B Master, the levels of the channels called by the B Master increase. Move the A
and B Master sliders together to fade from one preset to the other.
CROSSFADE TIMER
The A and B Masters are connected to an internal fade timer which allows a constant fade in/out time, no
matter how fast the master sliders are moved.
The fade time is adjusted by means of the RATE rotary switch and is stored by pressing the button marked
FADE/CHASE. The minimum setting (anti-clockwise) gives the longest fade time, approximately one minute.
The maximum setting gives instantaneous crossfade. This fade time range can be exchanged for a fade time
range of 0-10 seconds (see OPTIONS section).
DESK BLACKOUT
Selecting DBO disables all outputs from the Q12. The red LED flashes when DBO is active. Switch back
to Desk On to enable the outputs.
FLASH BUTTONS
Each channel has a flash button which allows the channel to be brought to 100% for as long as the but-
ton remains pressed. Only the Grand Master has priority over the flash buttons.
