3/4 way setup - Bi-Amp Mid/High

Using the Digital Input
• Digital Input 44.1 or 48kHz must be

present in the Digital Input.

• Press and hold the DIGITAL IN button

on the front panel until digital lock is
achieved. 

Note: The signal present on the DIGITAL
INPUT is passed unprocessed to the
DIGITAL THRU connection on the rear
panel for further downstream processing.

This example shows how 2 MACH M20.04s
can be used in conjunction to distribute
Input signals to a 3 or 4 way system per
side.

For each side:
• Source signal can be connected to either

Inputs A or B as only one Input per side is
used. For this example - use Input A on both
controllers.

• Configure the Routing section as illustrated

below.

• Set Crossovers and additional parameters.
