12V In Jack
The Zamp v.3 12V input uses a 2.5mm sub-mini jack.
To trigger the Zamp v.3, insert the trigger wire plug into this jack and the plug at the wire’s
other end into the preamp or controller’s trigger output jack.
Note:
If the preamp or controller’s trigger output is a + and – terminal, you can cut the 3.5mm
plug off one end of the included trigger wire and attach the bare wires to these termi-
nals. The lead with the white stripe on it corresponds to the plug’s tip and the unmarked
lead corresponds to the sleeve of the plug.
Note:
If the trigger voltage source is DC, the trigger plug tip must be + (positive) and its sleeve
“–“ (negative).
12V Trigger Out Jack
The Trigger Out jack lets you loop or “daisy-chain” the incoming trigger voltage to an additional
Zamp v.3 or other component.
Note:
The Zamp v.3 trigger circuit draws a negligible 15 mA from the controller. The total load
on your controller’s trigger output(s) is the sum of the trigger current drawn by each of the com-
ponents you’ve looped together. Check the maximum capacity of your AV receiver, processor or
home controller’s trigger outputs so you do not overload them by connecting too many power
amplifiers. Typical ratings are 50mA to 100mA.
AC Power Connections and AC grounding
If possible, plug your Zamp v.3 into the same AC outlet that your accompanying audio components
(especially the system controller) are plugged into. The ground potential between different AC
outlets may be higher or lower, resulting in audible hum.
