NOTE: To prevent loud potentially damag- ing noises, make sure the amplifier is turned off when you make any changes to the input signal configuration.
Input Selector Switch
Set the switch select the inputs that are being used. Set it to Unbalanced if the RCA inputs are used. Set it to Balanced if the XLR inputs are used.

Polarity and Phasing
The polarity — the positive/negative orien- tation of the connections — for every speaker and amplifier connection must be consistent so all the speakers will be in phase. If the po- larity of one connection is mistakenly reversed, bass output will be very weak and stereo im- aging degraded. All wire is marked so you can identify the two conductors. There may be ribs or a stripe on the insulation of one conductor. The wire may have clear insula- tion with different color conductors (copper and silver). There may be polarity indications printed on the insulation. Identify the positive and negative conductors and be consistent with every speaker and amplifier connection.

If you are using dual banana plugs, connect them to the wires and then plug into the backs of the binding posts. The hexagonal thumb- screws of the binding posts should be screwed in all the way (clockwise).
If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip back the insulation from the end of each conductor. Be careful not to cut into the wire strands. Unscrew (turn coun- terclockwise) the binding post hexagonal thumbscrews. Place the connector lug or wire around the binding post shaft. Turn the hex- agonal thumbscrews clockwise to clamp the connector lug or wire firmly in place.
Note: Be sure there are no loose wire strands that could touch adjacent wires or connectors.
