CONNECTING A SURROUND CONTROLLER
TO THE UNBALANCED INPUTS ON YOUR A 51
Ch 1-5 Unbalanced Inputs
Use these inputs if your surround controller doesn’t have balanced output connectors or if you
simply prefer to use unbalanced connections.
What You’ll Need:
•
Five shielded interconnect cables with RCA plugs
•
A surround controller with five RCA output jacks
Before Connecting
❑
Leave the AC cord on the A 51 disconnected until you have made all other connections to
prevent any surprise burst of sound.
❑
Make sure that all your cables are long enough so they are not pulled or stretched once
they are connected.
❑
Make sure the Balanced-Unbalanced Input Select switch on the A 51 is in its Unbalanced (right)
position and the Ground switch is in its Normal (down) position.
To Connect
1
Plug one end of the cable into the
Unbalanced Ch 1 Input jack
on the A 51.
2
Plug the other end of the cable into the unbalanced output jack for the channel on your
surround controller that you wish to correspond to Ch 1 on your A 51.

YOU SHOULD KNOW
Write Down Your Connections
Make a note of which channel on your surround controller now connects to each channel
of the A 51 so you’ll always hear the channels in their intended position and to facilitate
trouble-shooting in case you encounter a problem later on.
