YOU SHOULD KNOW

you can cut one plug off the cable and terminate the end as required. The lead with the
stripe is positive and the lead without the stripe is negative.

2.5 mm sub-mini plug
Whenever the A 21 is turned on either manually or automatically, there is 12 Vdc present
at its own DC Trigger Out jack so it can trigger additional amplifiers or other components
on and off.
What You’ll Need:
• A cable with a 2.5 mm sub-mini plug on each end
(in addition to the one provided with the A 21)
• A component that can be triggered with an external
+9 Vdc to +12 Vdc source. The A 21 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 the trigger wire into the 12V Output jack on the A 21.
Plug the other end of this wire into the component that you want the A 21 to trigger.
