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 ex9 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 

j

ack 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.
