Parasound JC 1 Amplifier - Manual (Page 10)

Whenever the JC 1 is turned on either manually or automatically, it generates 12 Vdc at its 12 V Trigger Out jack so it can trigger
additional JC 1 amplifiers or other components on and off.
What You’ll Need:
A second wire with a 2.5 mm sub-mini plug on each end (not provided)
A component that can be triggered with an external +9 Vdc to +12 Vdc source.
(The JC 1 DC Trigger output provides up to 150 mA of current.)
Before Connecting
Remove power to all the components in your audio system.
To Connect
Plug one end of this trigger wire into the 12 V Output jack on the JC 1
Plug the other end of this wire into the component that you want the JC 1 to trigger.
Automatic Turn On Delay Time
You can delay the JC 1 turn on time so it doesn’t turn on at the same instant as your
other components (or other JC 1s). This avoids turn-on surges and brownouts that might
cause units with microprocessors to lock up, or even trip house wiring circuit breakers. If
you’re lucky enough to own more than one JC 1, select a different delay time for each
unit. Turn the Delay knob for the desired delay time from None (fully counterclockwise) to
12 Seconds (fully clockwise).
YOU SHOULD KNOW
If the device use your JC 1 controls doesn’t have a 2.5 mm trigger output connector, you can cut
one plug off the trigger wire and terminate the end as required. The lead with the stripe is positive
and the lead without the stripe is negative.
