20. DOWN/BEAT REV button:

DOWN: Decreasing the level of a channel in edit mode: <DOWN/BEAT REV> + <PRESET A/B
x>

CHASE REV: used to change the direction of all the chases of which the speed is stored in a
preset B fader.
21. AUDIO LEVEL fader: This fader allows you to set the audio level. When the audio mode is active (see
number 6), scenes and chases will be played on the rhythm of the music.
22. SPEED fader: Used to set the chase speed. Look at the schedule below to easily set your speed (x
means a digit between 0 and 9):
Display Time
0.xx Milliseconds: For example 0.10 means 100 milliseconds
x.xx Seconds: For example 1.20 means 1 second and 200 milliseconds
xx.0 Seconds: For example 10.1 means 10 second and 100 milliseconds
x.xx. Minutes: For example 1.05 means 1 minute and 5 seconds
xx.x. Minutes For example 10.0. means 10 minutes
Sho Show mode

There are 2 possibilities of range for the speed fader:
o <RECORD/SHIFT> + <5>, <5>, <5> for the 5 min range
o <RECORD/SHIFT> + <10>, <10>, <10> for the 10 min range

You can store the speed in a preset B fader with
o <MODUS SELECT/REC SPEED> + <PRESET B x>
o Put the SPEED fader in the lowest position (SHOW MODUS) to erase the stored time
23. FADE fader: Used to store the fade time. Look at the schedule below to easily set your speed (x means
a digit between 0 and 9):
Display Time
0.xx Milliseconds: For example 0.10 means 100 milliseconds
x.xx Seconds: For example 1.20 means 1 second and 200 milliseconds
xx.0 Seconds: For example 10.1 means 10 seconds and 100
milliseconds
x.xx. Minutes: For example 1.05 means 1 minute and 5 seconds
xx.x. Minutes: For example 10.0. means 10 minutes
24. MASTER B fader:

Single preset mode: no influence

Double preset and Chase/Scene mode: Master of the preset B faders, the lowest position means
100%, the upper position is 0%
25. MASTER A fader:

Single preset mode: Master of Preset A and B faders, the lowest position is 0%, the upper
position is 100%

Double preset and Chase/Scene mode: Master of Preset A faders, the lowest position is 0%, the
upper position is 100%
26. PRESET A faders: Use these faders to set the values of channels 1 to 12
27. FLASH A buttons: When you press a flash button you will set the intensity of this channel to 100%
28. PRESET B faders:

Single preset mode: use these faders to set the values of channels 12 to 24.

Double preset mode: using this mode, you will work with a 12 channels A/B control, by which
every channel A/B fader will lead up to the same.

Chase/scene mode: This mode of the control allows you to store a whole (24 channels)
scene/chase on a preset B fader. You have 4 pages and 12 preset B faders, so you can store 48
scenes/chases.

29. FLASH B buttons:

Single preset mode: use these buttons to maximize the intensity of the channels 12 to 24 temporary
(See flash A buttons for more information)

Double preset mode: The flash B buttons control the flash A buttons

Chase/scenes mode: Used, together with the RECORD/SHIFT button, to store chase in preset B
faders. When you press and hold these flash buttons, the chase that is stored in the channels will
start to play.
30. STATE LEDs channel 1-12: Show the intensity of the channel in question.
31. STATE LEDs channel 13-24: Show the intensity of the channel in question.
32. STATE LEDs chases: when you move a preset B fader and the orange led above this channel is lit, a
chase is stored in this channel. The intensity of the leds corresponds with the intensity of the chase.
33. SPEED/FADER/DIMMER/REC STEP ACTIVITY LEDs: The speed time led will be for example lit when
you move the speed fader.
34. DISPLAY: shows the current action or the state of programming of the scenes/chases.
FUNCTIONS (REAR)
1. DC INPUT: connect the supplied AC/DC adapter to this input. If you should use another adapter, please
make sure that it has 9 ~ 12Vdc and minimum 300mA with + in the center.
2. MIDI TRU(left)/OUT(middle)/IN(right): You can attach an external MIDI-controller to these connections
(for more information, see chapter "how to use")
3. DMX OUTPUT: Sends DMX-signals to the connected fixtures
4. DMX POLARITY SWITCH: A DMX-signal normally has the following connections:
In some cases it happens that a cable is inversed, as a result of this the DMX-connection doesn't work.
This can be solved by using this switch. If your DMX connection doesn't work and all your DMX-
receivers are properly addressed, you can check this switch. In normal conditions always put this switch
in the left position.
5. AUDIO input: Here, you connect an audio line signal, so the connected light effects/lamps will react to
the music.
6. REMOTE connector: Using a stereo JACK you can switch the output in BLACK OUT or FULL ON:

HOW TO USE...
This chapter will explain step by step how the CMX24 works. We advise to read this text step by step.

Switching on:
The CMX24 hasn't got an ON/OFF switch. You have to connect the adapter that is delivered together with
the CMX24 to the DC INPUT connector and the mains. As soon as this happens, the CMX24 will be switch
on.

Connecting with dimmers:
The CMX24 is equipped with an 3 contact female XLR connector DMX OUT. Besides the connector there is
a slide switch that selects the polarity of the DMX-signal. Normally, this slide switch is switched towards the
side of the XLR-connection.
When the connected DMX-devices don't function correctly, switch this slide switch in the other position.

The Ring of the JACK to the mass: BLACK OUT can be switched ON/OFF.
The Tip of the JACK to the mass: FULL ON is active as long as the tip is connected to the mass.
