SP260 2x6 Speaker Processor Appendix B: Connections XLR Connectors The SP260 has two female XLR input jacks that accept balanced line-level signals. When connecting a balanced signal, be sure it's wired per AES (Audio Engineering Society) standards: SHIELD 2 HOT COLD 3 1 SHIELD 1 COLD 3 2 HOT 1 3 2 Balanced XLR Connectors SHIELD COLD HOT XLR Pin 1 - Shield (Ground) Pin 2 - Hot (+) Pin 3 - Cold (-) You should use high-quality, shielded cable to connect the signal source to the input jacks on the SP260. • High quality microphone cables work well. • Foil shielded cables are commonly used for audio wiring. • The better the shield, the better the immunity from externally induced noise (like EMI and RFI). Route the cable away from AC power cords and outlets. These are common sources for hum in an audio signal. You can purchase quality cables from your Mackie dealer. Additionally, there are six male XLR output jacks on the SP260. These are also wired according to the AES standards listed above. 24 SP260 2x6 Speaker Processor
