8. CONFIGURING THE DRM 4000

The DRM 4000’s BASIC CONFIGURATION is active whenever no CONTROL INPUT is connected to
ground. The DRM 4000’s factory-pre-set BASIC CONFIGURATION is 8-in-2 mixer. 

The following example shows the wiring for a typical 8-in-2 mixer application of the DRM 4000.

The freely programmable CONTROL INPUTS allow switching to other configurations. Therefore, the
corresponding CONTROL INPUT needs to be connected to ground. The eight CONTROL INPUTS are
factory-pre-set to the empirically most frequently used configurations. In most cases, using the configu-
rations described in the additionally supplied leaflet 

DRM 4000 FACTORY CONFIGURATION

 will provide

a solution for most common applications. For individually programming BASIC CONFIGURATION and
CONTROL INPUTS, please refer to chapters 6.4 and 7.
