Question:  Ihave a question about the cable needed to make IFB Controller to IFB ControlPanel connections using a 6-pin XLR-F to 6-pin XLR-M. Do you know of an alternative to Belden 8725 cable?
Answer:
Use one multi-pair cable for each group of four channels when connecting the IFB lines between the access stations and their associated component (other MA-704s or AX-704s and the PIC-4704). This cable must have (four) separately shielded conductors or pairs of conductors to prevent crosstalk. Suitable cable types are: Alpha #6054, Belden #8725 or 9330, and Mogami #2602. As noted in the previous section, the resistance buildup in both the power and common (or ground) conductors must be kept at a minimum for proper operation. Resistance buildup in the common conductor will also increase crosstalk.

Follow the diagram below for best results in connecting the cable to the XLR connectors.  Notice that all four of the spare conductors in each pair are tied together to pin 2 (DC power), and all shields are tied together to pin 1 (common). This arrangement minimizes resistance buildup effects in long cable runs.  Clear-Com has ready-made cable in 25, 50, and 100 foot lengths to fit your cabling and system architecture needs.
