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 Systems 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 Systems Integration Amplifier. Alternatively, the 12V trigger from the keypad can be used to turn-on the amplifier only when Zone 4 is active.
