9. Zone Control Inputs 1-12 (RJ-45)

These RJ-45 connections are used to receive control information from up to 12 ZC wall panel control- lers.

10. Word Clock BNC Connection

This connection allows the DriveRack 4800 or 4820 to lock to a master system clock. It is not termi- nated. For best results we recommend using “T” connectors when setting up a BNC Word Clock net- work and terminating the end of of this network with a 75 ohm BNC terminator. (See Appendix 6).

11. Pin Lift Switch

Analog Inputs 1&2, and 3&4 of the DriveRack 4800/4820 share a Ground Lift Switch (Pin 1 lift).

System ground loops can cause hum; this hum can be reduced by pressing the Ground Lift Switch.
