12 Volt Jacks
12V In Jack
The Zamp Quattro 12V input uses a 3.5mm mini jack (mono). To use the 12V trigger, insert the
trigger wire plug into this jack and the plug at the wire’s other end into the AV receiver or preamp’s
12V output jack. We have included a 3.5mm mini plug to 3.5mm mini plug trigger wire as well as a
3.5mm mini plug to 2.5mm sub-mini plug trigger wire.
Note:
If
the 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 terminals. 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. The trigger plug tip is + (positive) and its sleeve
– (negative).
Note:
The Zamp Quattro trigger circuit draws a negligible 10 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
controll
er’s trigger outputs so you do not overload them by connecting too many power
amplifiers. Typical ratings are 50mA to 100mA.
12V Out Jack
The 12 volt output jack on the Zamp Quattro is an active output (not just a looping output) so it is
live whenever the Zamp Quattro is on, even it was turned on manually or by an audio signal.
Because this is an active output you can use the Zamp Quattro to trigger additional equipment. For
example if the Zamp Quattro’s Turn On Option switch was set to Audio, when the music or audio
signal starts the Zamp Quattro will turn on and immediately supply 12V to the 12V out jack. This
could be used to trigger additional amplifiers or other equipment such as the Parasound Zbreeze
Cooling Fan.
3.5mm vs. 2.5mm jacks
Some other Parasound power amplifiers and preamplifiers might use 2.5mm “sub-mini” trigger
jacks. To use the Zamp Quattro with products that use a 2.5mm jack we have included a trigger
wire with a 3.5mm plug at one end and a 2.5mm plug at the other end.
NOTE: If the rear panel Turn On switch is set to Audio or
12V the front panel Power button is disabled.
AC Line Power Cord
Connect your digital sources and analog preamplifier before you plug in the AC cord.
The power cord supplied with your Zamp Quattro is a IEC type AC cord. The AC ground potential can
vary between your AC outlets, the result can be an audible 60Hz (or 50Hz) hum heard in your speakers.
To help avoid this problem plug your Zamp Quattro into the same AC wall outlet, power strip or line
conditioner as all your other audio equipment.
