12 Volt Trigger Jacks by Zone
12V In Jacks
The ZoneMaster 650
“12V All
”
jack and three 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).
Note:
Each 12V input jack draws a negligible 5 mA. The total load on your preamp
’s trigger
output(s) is the sum of the trigger current drawn by each of the
components you’ve
looped together. Check the maximum capacity of your AV receiver, processor or home
controller’s trigger outputs so you do not overload it by connecting too many power
amplifier trigger inputs. 12V trigger outputs are typically rated for 50mA to 100mA.
12V Out Jacks
The Trigger Out jacks are powered (active outputs) which allows the ZoneMaster 650 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. For example, if you wish
to turn on zones 1 and 2 by the same 12V source you would connect the 12V trigger source to the Zone
1 12V input jack. Then connect a trigger wire from the Zone 1 12V output jack to the Zone 2 12V input
jack.
AC Line Power Cord
Connect your sources and preamplifier before you plug in the AC cord.
The power cord supplied with your
ZoneMaster 650 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 650 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.
