Delta Series Audio Controllers
Matrix Keypad plus Analog Volume Controls
In cases of split zones where more than one set of speakers are driven from the same zone output (such as
a master bath off of the master bedroom) it is sometimes desirable to place independent volume controls
in the split zones while retaining the Delta Keypad for source control and ON/OFF functions.
FIG. 10 shows the connections to a remote zone and “
Autoformer
” volume control devices.
The secondary analog volume control “taps off” of the L+, G and R+ terminals of the DELTA
CONTROLLER OUTPUT. The G terminal connects to both L- and R as shown. This allows
independent volume in each “sub zone” with the Delta Keypad being the source control and
ON/OFF switch.
The main keypad wiring uses all four conductors and then a secondary analog volume control
“taps off” of the L+, L-, R- and R+ terminals of the SPEAKER OUTPUT for the main zone.
