What is a "Channel" anyway?
The LM-850 console has 54 "Control Channels" in 3 banks of 18 faders.
The LM-850 Soft-Patch lets you control each of 108 "Dimmer Channels" from any control channel.
Channel level data for these 108 channels is sent to dimmers thru the console’s MIDI, DMX or Analog
outputs.
Each LD-360M Dimmer Pack has Six "Dimmer Pack Channels" which can be set to respond to any six
sequential Dimmer Channels.
There are sixteen "MIDI Channels" in a MIDI output on which the LM-85O can send data, and to
which each pack can selectively respond.

Basic System Hook-Up
Integrating the LM-850 into a standard lighting system is a simple process. A convenient system can
be set up using MIDI-controlled dimmers, such as Leprecon’s LD-360M and LD-360M-HP. In this
situation the three MIDI Dimmer Interface outputs are used to send data to the dimmers (see Figure 1).
Any number of dimmers can be used, and all should be set to the same MIDI channel as the console’s
MIDI dimmer output. Each dimmer must be assigned a specific “starting address" so that its channels
are assigned to the correct control channels. Dimmers having the same starting address will be con-
trolled simultaneously by the same console faders.
IIru
A typical setup using the LM-850 and numerous MIDI-controlled dimmers.
Multiple MIDI dimmers can be connected either to the three Dimmer outputs on the LM-850’s rear panel
(all three work in parallel-it doesn’t matter which is used), or the dimmers can be daisy-chained. In this
situation, the console’s MIDI Out To Dimmers is connected via a normal MIDI cable, to the MIDI In of
the first dimmer. Then, a second MIDI cable is run from the MIDI Thru of that dimmer to the MIDI In of
the next dimmer, and so on. So a MIDI dimmer can be plugged into either a Dimmer MIDI Out from the
LM-850 or into the MIDI Thru of any other connected dimmer. You will need to make sure that the
console’s Dimmer Output is assigned to “MIDI" and once again that both the console and the dimmers
are all on the same MIDI channel. At this point, you should be able to plug lamps into the dimmers, and
begin operating the board.
