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:
Balanced XLR Connectors
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.
