CONNECTING A SURROUND CONTROLLER
TO THE BALANCED INPUTS ON YOUR A 52
Left and Right Balanced Input Jacks
Balanced connections will give you the best sound. If your surround controller has balanced
XLR output jacks, we recommend that you connect them to these inputs. Refer to the Balanced
and Unbalanced Lines in the Technically Speaking section for additional information about why
we recommend using balanced lines.
What You’ll Need:
•
Five balanced interconnect cables with XLR connectors
•
A surround controller with balanced output connectors
Before Connecting
❑ Leave the A 52’s AC cord 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 strained or stretched
once they are connected.
❑ Make sure the Balanced - Unbalanced Inputs selector switch on the rear of the A 52 is
in its Balanced (upper) position. The Ground switch should be in its Normal (lower) position.
To Connect
1 Plug the male end of the first balanced interconnect cable into the Balanced Ch 1 input
jack on the A 52.
2
Plug the female end of the cable into the balanced output jack for the channel on your
surround controller that you wish to correspond to Ch 1 on your A 52.
3 – 0 Repeat steps 1 and 2 above to connect Ch 2, Ch 3, Ch 4, and Ch 5.

YOU SHOULD KNOW
Balanced XLR Jacks and Their Pin Configuration
The balanced inputs of the A 52 use XLR jacks that conform to the industry standard of:
Pin 1: Ground, Pin 2: Positive (+), Pin 3: Negative (–). The balanced outputs on some com-
ponents use terminals with 3 screws instead of XLR jacks. These are compatible with the
A 52 as long as you match the bare wires to the corresponding pins on the XLR plug: + to
pin 2, - to pin 3, and Ground to pin 1.
