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.

Before Connecting

What You’ll Need:

•Five balanced interconnect cables with XLR connectors

•A surround controller with balanced output connectors

❑Leave the A 51’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 Input Select switch on the rear of the A 51 is in its Balanced (left) position and the Ground switch is in its Normal (down) position.

To Connect

1Plug the male end of the first balanced interconnect cable into the Balanced Ch 1 input jack on the A 51.

2Plug 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 51.

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 51 use XLR jacks that conform to the industry standard of: Pin 1: Ground, Pin 2: Positive (+), Pin 3: Negative (--). The balanced outputs on some components use terminals with 3 screws instead of XLR jacks. These are compatible with the A 51 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.
