CHAPTER 3 | INSTALLATION AND OPERATION
EXPANDING TO EIGHT OUTPUT ZONES
It is possible to expand the number of output zones using two AD-4x Audio
Distribution Systems together. This allows four local audio sources to be
delivered to eight zones.
Local Source Cabling
A "Y" cable will need to be used to split the audio output of the local audio
source and wired to the local audio source inputs on both AD-4x units.
NOTE: It is not possible to "Y" or split the audio signals from the RSP-1 to
multiple AD-4x units, limiting their output to a maximum of four zones.
AD-4x #1
AD-4x #2
Controlling Multiple AD-4x's using RS-232
Each AD-4x will require an RS-232 connection to an RTI control processor. This
will allow each AD-4x to be controlled separately, allowing for independent
control in all eight output zones.
