18 Delta Series Audio Controllers
Auxiliary Amplifier Configuration (Zones 2-6)
In cases where you require more power for a given zone than the Delta Controller can provide and it is
other than in Zone 1, use this diagram. It shows use of a Matrix LLC device designed to reduce the
“speaker level” output of the Delta Controller to “line level” so that it can drive an auxiliary amplifier.
This amplifier would typically be installed at the equipment rack (source end).
Remote Amplifier Configuration
In some cases, especially where the distance between the Delta Controller and the zone is unusually
long, such as another building on the property i.e. cottage-to-boathouse for example, it is sometimes
desirable to have a remote amplifier at the zone end. This diagram could also represent the Matrix LLC
device implemented so that there is a preamp level output available for a remotely mounted amplifier
elsewhere on the property. The main difference is the run of 4 conductor wire between Delta and the
Matrix LLC device (FIG. 12).
