preamp. An XLR plug is “keyed” so that it fits into the socket only one way. If there is a set-screw in the barrel of the plug, align it with the top of the connector. Push the plug fully into the XLR socket until it latches in place. The three pins of an XLR-type (“Cannon”) connec- tor are numbered. Pin 2 is the signal “hot” connec- tion; in the 218 THX, Pin 2 is connected directly to the center pin of the unbalanced RCA phono jack. Pin 3 is the signal return (signal ground) connection. Pin 1 is the chassis earth (ground), to which the shield of a balanced-wire cable is connected. UNPLUGGING. The XLR socket has a latching feature that prevents the connector from being pulled out by accident. Before disconnecting an input cable, turn off the Power. Use one hand to press the latch- ing tab above the XLR socket while using the other hand to pull the XLR plug out. 4. RIGHT CHANNEL INPUTS (Balanced, Unbalanced). Make connections to the right-channel input in the same way that you did for the left channel. 5. INPUT SELECT (Balanced/Unbalanced). Set this switch to match your selection of input connector. Set to UNBAL if you have connected a cable from your preamp to the RCA phono input jacks. Set the switch to BAL if you are making con- nections to the balanced XLR inputs. Normally the choice of input connector is deter- mined by the output connectors on your preamp. If your preamp has balanced outputs, use three-con- ductor cables equipped with XLR connectors. If your preamp has only “unbalanced” connections with RCA phono jacks, use the corresponding inputs on the 218 THX. It is possible to connect an “unbalanced” source (such as a CD player) to the XLR inputs, by means of adapter cable in which the audio-retur...
