JL Audio MCS-3800 manual Set the Expander ID#, Important Be Sure Each Expander has a Unique ID#

Set the Expander ID#

On the rear of the Expander is a small cluster of four switches, known as DIP switches.

When the rear dip switch number 4 is up, that is, off, the 3 remaining switches are used to set the “ID” number of the 3000X Expander.

These switches set the ID# of each Expander, so the system knows which Expander represents channels 1 through 8, which is 9 through 16, etc.

Set the left-most Expander for ID#1 by making sure that all four switches are up, that is, off.

Follow this chart to set the ID# of multiple units. Off = Up

#4	#3	#2	#1	ID#	Fader Numbers
off	off	off	off	1	9 - 16
off	off	off	on	2	17- 24
off	off	on	off	3	25- 32
off	off	on	on	4	33- 40
off	on	off	off	5	41- 48
off	on	off	on	6	49- 56
off	on	on	off	7	57- 64

Important: Be Sure Each Expander has a Unique ID#

A multiple expander system will not operate correctly if two or more units are set to the same ID#.

On power-up, turn the Expanders on before the MCS-3800. The MCS-3800 LCD will display the number of 3000X units connected.
