Delta Series Audio Controllers
Auxiliary Amplifier Configuration (Zone 1)
In some cases you may require more power for a given zone than the Delta Controller can provide.
FIG. 11 shows how to utilize the preamp RCA outputs on the Delta Controller for an external amplifier.
This may be useful when outdoor or large rooms make up the zone, or in situations where the number of
speakers will require a multi-channel amplifier to safely power them all.
This configuration shows an external power amplifier connected to the “LINE OUT” connections on the
back of the Delta Controller. These connections are only available on Zone 1. The corresponding Zone 1
keypad would connect to the Delta Controller with only the D and G connections. The power amplifier
will handle the individual speaker connections which means the amplifier and the speakers can be placed
at distances from the Delta Controller not usually practical. It also allows an easy solution when you
simply need more power in the zone than the Delta Controller provides
