Frequently Asked Questions - LM 140 JBSYSTEMS LIGHT

How does the standalone mode work?

In standalone mode, all DIP-SWITCHES must be in the OFF position. Use the PROGRAM button to select one of the 3 programs or the carousel. AUDIO mode (red LED) activates the internal microphone to modulate to the rhythm of the music. CHASE mode (green LED) cycles through the channels at the speed set by SPEED.

How to adjust the microphone sensitivity?

Turn the SENSITIVITY potentiometer to adjust the sensitivity of the internal microphone. High sensitivity reacts to weak sounds, low sensitivity requires loud sound.

How to use DMX mode?

For DMX mode, connect an external controller. If the DMX-ADRESS DIP-SWITCH is ON, the 4 outputs are addressed on a single DMX channel (1-512). The controller sliders allow SWITCH PACK (on/off) and AUDIO/CHASE (activation of standalone mode at 100%) modes.

What is the maximum load per channel?

The maximum load per channel is 1 200 W for inductive and resistive loads. The output current is limited to 5 A per channel.

How to replace the fuse?

Unplug the unit. Replace the fuse with an identical model: F 6.3 A / 250 V (5 x 20 mm). Use a screwdriver to open the fuse holder.

What type of plug to use?

The unit must be plugged into a grounded outlet (230 V ~ 50 Hz). To avoid overloads, install a 20 A circuit breaker and limit total consumption to 16 A.

What to do if the device does not turn on?

First check the fuse and replace it if necessary. Make sure the outlet is powered and that Stand-by is not activated. If the problem persists, consult a technician.

How to select the programs?

In standalone mode, press the PROGRAM button to choose between the 3 programs or carousel mode (automatic rotation of programs). The programs define the order and behavior of the channels.

What is the difference between audio and chase mode?

In AUDIO mode, the channels react to the rhythm of the music captured by the internal microphone. In CHASE mode, the channels light up sequentially at a speed set by the SPEED potentiometer, independent of sound.

How to address the device in DMX?

Set the DMX-ADRESS DIP-SWITCH to ON to use a single DMX channel (1-512). Use the DMX controller sliders to activate the SWITCH PACK (on/off) or AUDIO/CHASE (activation of standalone mode at 100%) functions. The percentages indicate the slider positions.

USER MANUAL LM 140 JBSYSTEMS LIGHT

This 4-channel modulator works in STAND ALONE (A) or with an external DMX-controller (B).

A. Audio / Chase

To use this function, all DIP-switches must be in the OFF-position.

1. The PROGRAM - button allows you to select a program: choose between programs 1, 2, 3 and Random (programs will be played randomly).
2. AUDIO: When the red LED is lit, the program will be played based on the rhythm of the music.
3. SENSITIVITY: This rotary pot adjusts the sensitivity of the built-in microphone. Turn the knob clockwise for higher sensitivity.
4. CHASE: when the green LED is lit, the chaser is activated.
5. SPEED: with this rotary pot the speed of the chaser can be set.

CHANNEL: Flash knob with LED-indicator per channel.

B. DMX

To use the LM 140 in DMX-mode, an external DMX CONTROLLER has to be used.

1. DMX-ADRESS: When in ON-position, each of the 4 channels can receive a different DMX-adress (from 1 till 512).
2. SWITCHPACK/CH: The dimming level of the LM 140 is now comparable to the dimming level of a regular switchpack. This means that if the dimming level is smaller than 50% , the channel will not be activated (STAND BY). If the dimming level is more than 50% , the channel will be FULL ON.
3. SWITCHPACK/4CH: same as SWITCHPACK/CH (2), but for all 4 channels instead of one specific channel.
4. AUDIO / CHASE: The modulator now works as a regular chaser. When a channel is activated, it will be activated for the full 100 % (FULL ON).

REMARK:

When talking about percentages (%) , we refer to the dimming level of the external DMX-controller. So, when the cursor of the DMX-controller is in the middle, the percentage is 50% , 100% is full-on, 0% is stand-by.

Attention

This apparatus must be earthed at all times.
- To prevent electric shocks or fire: do not expose this equipment to any kind of moisture.
- To prevent DC/Current: install an automatic 20 A fuse, and limit the total power consumption to 16A .

When replacing the fuses, always make sure to replace them with fuses of the same dimensions and characteristics.
