CONNECTING THE A 21 LOOP OUT JACKS

TO ANOTHER POWER AMPLIFIER’S INPUTS
Loop Out Connector
The Right and Left Loop Out jacks provide connections to route the same input signals from your preamplifier or surround controller to an additional power amplifier. In most instances, you won't use the loop out feature so you can skip this section.
What You’ll Need: | Left | |
• One pair of shielded interconnect cables with RCA plugs | Right | |
• An additional amplifier | ||

| RCA Plugs |
Before Connecting
Leave the AC cord on the A 21 disconnected from the wall until you have made all of the connections in the system to prevent any surprise burst of sound.
Make sure that your interconnect cables are long enough so they are not strained or stretched once they are connected.
To Connect
1Plug one end of the cable to the right channel Loop Out jack on the A 21.
2Plug the other end of this cable to the right channel input jack on the other power amplifier.
3&4 Repeat steps 1 and 2 for the left channel.

YOU SHOULD KNOW
These jacks eliminate the need for two “Y” connector cables to split the outputs from the two source channels between your A 21 and another amplifier. The A 21 Loop Out Jacks jacks provide the same signals that are received at either the balanced or the unbalanced inputs. Refer to Loop Out Jacks in the Technically Speaking section for more information about when to use the Loop Out Jacks.
