12 Volt Trigger Jacks by Zone
12V In Jacks
The ZoneMaster 4 “12V All” jack and two individual zone jacks are 3.5mm mini jacks (mono). To use a
12V trigger, insert the trigger wire plug into the jack and the plug at the wire’s other end into the AV
receiver or house controller’s 12V Output jack. We have included two trigger wires with 3.5mm mini plug
at both ends.
Note: If the controller’s or preamp’s 12V trigger output is a + and – terminal instead of a jack,
you can cut the 3.5mm plug off one end of one of the included trigger wires and attach
its bare wires to these terminals. The trigger plug tip is + (positive) and its sleeve –
(negative). Each 12V input jack draws a negligible 5 mA.
12V Out Jacks
The Trigger Out jacks are powered (active outputs) which allows the ZoneMaster 4 to trigger other
equipment with a 12 volt input such as additional amplifiers even if that zone is set to use the audio
trigger. This also gives you the ability to loop (or daisy chain) zones together.
AC Line Power Cord
Connect your sources and preamplifier before you plug in the AC cord. The power cord supplied with your
ZoneMaster 4 is an IEC type 16AWG AC cord. The AC ground potential can vary between your AC outlets
and the result can be an audible 60Hz (or 50Hz) hum heard in your speakers. To help avoid this problem
plug your ZoneMaster 4 into the same AC wall outlet, power strip or line conditioner as all your other audio
equipment.
Master AC Power Switch
The Master AC Power Switch is located to the right of the AC inlet. Press the side marked “0” for off; press
the side marked “|” for on. This switch will normally be left on but may be turned off if you will not be using
the amplifier for an extended period of time.
