Owner's Manual Appendix B: Connections Balanced XLR Input Connector Balanced 1/4" TRS Connector Each SRM loudspeaker has two female XLR/TRS/TS combo inputs. Be sure the cables are wired per AES (Audio Engineering Society) standards: Balanced XLR Input Connector Pin 1 - Shield (Ground) Pin 2 - Positive (+ or hot) Pin 3 - Negative (- or cold) SHIELD 2 HOT COLD 3 1 1 3 2 SHIELD COLD HOT Balanced XLR Input Connector TRS stands for Tip-Ring-Sleeve, the three connections available on a stereo 1/4" cable. This allows for a direct connection to the channel 1 and 2 input jacks on SRM loudspeakers.

Simply plug the signal source (i.e., mixer output) into the input jack(s), and patch that loudspeaker's THRU jack to the next loudspeaker's input jack, and so on, daisy-chaining multiple SRM loudspeakers. See page 8 for a visual representation of daisy-chaining. TS stands for Tip-Sleeve, the two connections available on a mono 1/4" cable. This allows for a direct connection to the channel 1 and 2 input jacks on SRM loudspeakers.
