PRE-AMP OUTPUT

Zone 4 is equipped with a pre-amp output to connect an external power ampliﬁer. If one room in the house is particularly large or requires

substantially higher volume levels, it is advised to assign this room to Zone 4 and connect a Niles System Integration Ampliﬁer

to provide

more powerful ampliﬁcation to the room's loudspeakers. The pre-amp output can be switched between a ﬁxed level or variable level.

12V TRIGGER OUTPUT

When any zone is activated, the ZR-4's Global 12V Control Output will send out a constant 12V DC trigger signal. This can be used to

automatically switch on an ampliﬁer equipped with a 12V trigger turn-on, such as a Niles System Integration Ampliﬁer. Alternatively, the

12V trigger from the keypad can be used to turn-on the ampliﬁer only when zone 4 is active.
