Zone 1-4 Super Module Design View

The Zone Super-modules create the mix for each

zone. Program 1 and the Aux Mix connect to an Input

Selector module to choose the primary audio source

for the zone. The output feeds the primary input of

the first Ducker module. The side-chain input for this

Ducker is the Program 2 input. This allows Program

2 audio (when present) to duck Program 1 audio. A

Mixer module is used to mix the Program 1 and 2 au-

dio, which then feeds the input of the second Ducker

module. The side-chain for this Ducker is the Paging

signal. This allows an incoming page to duck (over-

ride) either the Program 1 or 2 audio. Another mixer is

used to feed the SPL Computer modules in Zones 1 and

2. The SPL Computer modules are the Gap–sensing

type. The required Sense Input is connected to a mi-

crophone that monitors the zone. Zones 3 and 4 do not

have SPL Computers.
