SYSTEM CONFIGURATION 6
ZR-4 MULTIZONE RECEIVER WITH AN EXTERNAL AMPLIFIER IN ZONE 4
The ZR-4 MultiZone Receiver is designed to accommodate a separate amplifier to drive Zone 4’s loudspeakers.
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.
