Auxiliary Amplifier Configuration

In some cases you may require more power for a given zone than the Matrix Controller can provide. You may

purchase a DAS-LLC to provide a line level output to incorporate a larger external amplifier, or you can make

your own line level converter.

FIG. 26 shows the construction of a simple circuit of discrete components to reduce the "speaker level" output

of the Matrix Controller to “line level" so that it can drive an auxiliary amplifier.

This amplifier would typically be installed at the equipment rack (head end).

Remote Amplifier Configuration

In some cases, where the distance between the Matrix Controller and the zone is unusually long, it is

sometimes desirable to have a remote amplifier at the zone end. You may install a DAS-LLC to accomplish

this task or you may build your own. FIG. 27 shows the construction of a simple circuit of discrete components

to reduce the Matrix Controller output to “line- level” so that it can be fed into an auxiliary amplifier.
