Figure 6

Conversion from Style 7 to Style 4

Notes:

1. Use 18 AWG minimum wire.

2. Limit maximum resistance per pair to 80 ohms.
3. Use shielded twisted pair.
4. Terminate the shield ONLY at the MMB enclosure.
5. The wiring is power limited according to NFPA 70 per NEC

760.

6. Maximum voltage is 8V P-P.
7. Maximum current is 150mA.
8. Use the end of line resistor P/N 140-820150 (120 ohms, 

1

/

4

W).

See Figure 2E for further information.

9. Refer to Wiring Specification for MXL, MXL-IQ and MXLV

Systems, P/N 315-092772 revision 6 or higher, for additional
wiring information.

CONNECT ONLY
TO RCC-1/1F
OR MOI-7
