CONNECTIONS
CONNECTING AN A/B AMPLIFIER SWITCH FOR LOCAL SYSTEM SELECTION
A Niles SPK-1 Voltage-Activated Speaker Level A/B Switcher connects to both the A4.6Ci and a local system
to provide sound from each system to the same speakers located in a single zone. The local system only con-
nects to the speakers when the local system is turned on. The Niles A4.6Ci connects to the speakers by default
when the local system is off.
As shown in Figure 39, the zoned speaker output of the A4.6Ci connects to the "A" side of the SPK-1. The main
speaker output of the local system connects to the "B" side of the SPK-1. In addition, a 12V DC power adapter
(Niles FG00665) is plugged into a switched AC outlet of the local system to activate the SPK-1.
