FUNCTIONS (FRONT)

1. POWER SWITCH: used to switch the unit ON/OFF.

2. DIMMER CHANNELS: these are 4 faders used to set the individual dimming levels of the 4 channels.

Below each fader there’s a flash button to set the output of the corresponding channel to 100% (full) for

as long as the button is pressed. The flash buttons all have backlight so you can easily monitor the

output of each channel.

3. SWITCH CHANNELS: these buttons are used to switch 4 individual light effects ON/OFF. To be able to

use these buttons you must connect a separate switch pack to the DMX-output of the unit. (DMX

address on the switch pack must be set to 005)

4. MODE SELECT: used to select 1 of the 4 user modes:

 HOLD DIM: This mode can be used to control the dimming levels of projectors on a small stage.

The 4 faders (2) can be used to set the dimming level of each channel individually.

 HOLD SOUND: the music is divided into 4 different frequency ranges (bass, middle, high, anti-

bass). Each of the four output channels will respond to a different frequency range.

 PROGRAM SOUND: The chaser program selected with the “program select” button (6) will be

displayed. The chaser speed is synchronized to the rhythm of the beat.

 PROGRAM SPEED: The chaser program selected with the “program select” button (6) will be

displayed. The chaser speed can be adapted with the speed fader (12).

5. MODE SELECT INDICATOR: shows which of the 4 modes is currently active.

6. PROGRAM SELECT: When you selected 1 of the 2 program modes (4) then you can use the program

select button to choose the program you like. Nine different chaser programs (from 1 to 9) can be

selected. Program 0 (zero on the display) is a random program.

7. PROGRAM DISPLAY: shows which chaser program is currently selected.

8. MASTER DIMMER: controls the overall dimming level of the 4 channels.

9. FULL SWITCH: use this button to set the output of the 4 channels to 100% (full) for as long as the

button is pressed.

10. BACKGROUND LEVEL: with this fader you can set the background level (minimum output level) of the

4 dimmer channels. This can “soften” the chaser effects so they become less aggressive.

Attention: don’t set this fader to maximum, you will not be able anymore to see the chaser patterns or

set proper dimming levels for the 4 individual channels.

11. STANDBY SWITCH: used to cutoff (blackout) the output of the 4 dimmer channels. The 4 switch

channels are not affected.

12. PROG SPEED CONTROL: When the “program speed” mode (4) is selected, you can change the speed

of the selected chaser program (6) from slow to fast or very fast (13).

13. SPEED x10 BUTTON: Used to multiply/divide by 10 the speed selected with the speed fader (12).

14. AUDIO SENSITIVITY: used to adjust the input sensitivity of the internal microphone or external audio

inputs. Adjust the level until the sound activated functions work nicely to the rhythm of the music.

15. INTERNAL MICRO: the internal microphone is installed behind this opening.

16. SOUND SOURCE SELECT: used to select which audio input will be used to synchronize the sound

related functions:

 BUILT-IN MICRO: use this function when the music playback level is high enough so the internal

microphone can easily capture the sound. This is the easiest way to use the sound functions.

 AUDIO INPUT: use this function when the sound level is rather low. In this case don’t forget to

connect the audio input connectors (17)!

17. AUDIO INPUT: when the sound source selector (16) is set to “AUDIO INPUT” you will have to connect

these cinch/RCA connectors to an analog audio signal ranging from 200mV to 1000mV. In most cases a

record output or secondary master on your mixer will do.

18. DMX OUTPUTS: used to connect the light modulator to DMX power packs. You can use the 5pin XLR or

3pin XLR connectors. Both connectors carry the same signals, they only have a different pinning layout.

In most cases however you will use standard XLR-3pin male/female cables. Both the dimmer and switch

channels are available on these outputs:

 DIMMER CHANNELS: are assigned to DMX addresses 001 to 004. Please set the starting

address of the connected dimmer pack to 001.

 SWITCH CHANNELS: are assigned to DMX addresses 005 to 008. Please set the starting

address of the connected switch pack to 005.

Hint: You can connect all kinds of dimmer/switch packs, however for mobile applications we suggest

using the JB Systems

PB41/STD powered DMX-bars. You can easily set each channel in switch or

dimmer mode. Moreover you can directly fix your projectors and/or light effects to these powered DMX-

bars.

19. POWER INPUT: this input depends on the model number of the light modulator:

 LM430: low voltage input, connect the supplied AC adapter here. If you should use another

adapter, please make sure the output produces 15Vac (>1A) with positive pole (+) in the center of

the connector.
