The channel sliders are arranged in two scenes called X and Y. With the crossfaders both pushed to
the top of the slots, the X scene is active and channel levels set on the X scene appear on stage.
Levels for the next look may be set in the Y scene without affecting levels on stage. At the appropri-
ate time, the operator slides the crossfaders to the bottom of the slots, and the Y scene becomes ac-
tive and the look set in the Y scene appears on stage. Levels for a new look may then be set in the X
scene.
A show is typically run as a series of crossfades from the X scene to the Y scene and back again, but
there are additional controls available to "finesse" the production. The grandmaster slider affects all
channels proportionally and is used to fade to black or up from black. The blackout button is used for
a sudden blackout: all lights on stage go out and the LED flashes red, reminding the operator to
press the button again to leave blackout mode, preferably with the grandmaster slider down so the
lights can fade up smoothly from black.
Although the crossfaders are generally run up and down together, they may be split in either of two
directions. When split with the X fader up and the Y fader down, both scenes are active and "pile on",
i.e. the higher of the levels set in either scene takes precedence. When split with the X fader down
and the Y fader up, both scenes are inactive and the stage fades to black. Splitting the crossfaders
enables the operator to produce uneven fade rates or introduce a delay in the fade from one scene to
the next.
The SS/2S switch toggles the controller from two scene to single scene mode. The switch is only
read on power up, so be sure to remove power before changing the switch and apply power after
changing the switch. In single scene mode, the number of control channels is doubled. For example,
on the TM-TS12/24 the top row is channels 1-12 and the bottom row is channels 13-24. The hold
button adds a virtual second scene so the operator can crossfade from one look to another even in
single scene mode. Here is an example:
1. Remove power from controller.
2. Set the SS/2S switch to the SS position.
3. Push the crossfaders to the top of the slots.
4. Apply power to the controller.
5. Set light levels on the top & bottom rows of sliders.
6. Press the hold button. Note how the LED shines.
7. Set new light levels. Note how the look on stage does not change.
8. Slowly run the crossfaders to the bottom of the slots. Watch the levels change from one look to the
next. At the end, the hold LED goes out.
9. Press the hold button again, lighting the hold LED. Set new light levels. The stage look does not
change.
10. Slowly run the crossfaders to the top of the slots. Watch the levels change from one look to the
next. At the end, the hold LED goes out.
The console features a user programmable chase. In a chase, lamps are lit in sequence according
to the chase program. The level of the chase can be set with the chase level control. If manual fad-
ers are set to light some lamps at a particular level, the chase piles on that level (the higher of the
chase level or the channel level takes precedence). Note also that the chase level is affected by the
grand master and blackout controls. In addition to the level of the chase, the speed of the chase can
be varied with the front panel chase rate control. If either the chase rate or level is set to zero, the
chase is suspended and will start again when the level and rate are above zero.
The chase includes three chase modes. These are forward (green LED), reverse (red LED), and
build (yellow LED). Pressing the chase mode button switches from chase off to each of these
