Introduction

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 built­in 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 DMX­controller is in the middle, the percentage is 50%, 100% is full-on,
0% is stand-by.
