FUNCTIONS

(FRONT)

1. BLACK OUT button:

Used to switch between black out (every DMX value at 0) and normal. The led

beside the button blinks when the BLACK OUT function is activated. The DMX values will nevertheless
be shown trough the green leds. (see number 30/31)

2. FULL-ON button:

As long as this button is pushed in, all channels will have the same maximal intensity,

regardless the working mode and the black out function. The dark button (number 15) has priority above
the full-on button

3. TAP SYNC button:

By pressing this button twice you will adjust the chase speed. By moving the

{SPEED} fader, this stored speed will be erased. This doesn’t apply for the preset B faders (number 29)
of which the speed is stored.

4. HOME button:

Only useful in Chase/Scenes mode (check the chapter “How to use” for more

information). Using this button you can switch a channel that is set in BLIND mode (see <BLIND>
button) back in normal mode. So you have to press

<HOME> + <PRESET A/B x>

to switch a preset B

fader back in normal mode.

5. BLIND button:

Only useful in Chase/Scenes mode (check the chapter “How to use” for more

information). With this button you can switch a channel in BLIND mode. In this mode, the intensity of the
channel will only be determined by the preset fader (A for the channels 1 to 12, B for the channels 13 to
24) and the master A fader. Chases or scenes that are stored in a preset B fader don’t have an
influence. So, you have to press

<BLIND> + <PRESET A/B x>

to switch a channel in blind mode.

6. AUDIO button:

Using this button you can (de)activate the audio function (LED above the Audio button

is ON/OFF). When the audio function is active, the speed of the passing of scenes of chases will be
determined by an audio signal, acquired by the internal microphone or supplied by the LINE IN
connector (number 5 on the rear side of the CMX24). The {SPEED} fader, <STEP> and <TAP SYNC>
buttons don’t have an influence. You cannot use the audio function for chases of which the speed is
stored in a preset B fader.,

7. STEP button:

Using this button, you can view the scenes of chases manually. The {SPEED} fader has

to be set in the lowest position (SHOW MODE) or you have to work in the EDIT mode. This button
doesn’t have and influence on chases of which the speed is stored in a preset B fader.

8. HOLD button:

As long as you press this button, the current scene will be maintained. When you release

this button, the new scene will fade in with a time that is set with the FADE fader. With the DARK, FULL-
ON, BLACK OUT, PRESET buttons you can still change the scene.
