CHASSIS GROUNDING
If after hooking up your system it exhibits excessive hum or buzzing, there is an incompatibility in the grounding configuration
between units somewhere. Your mission, should you accept it, is to discover how your particular system wants to be grounded. Here
are some things to try:
1. Try combinations of lifting grounds on units that are supplied with ground lift switches or links.
2. If your equipment is in a rack, verify that all chassis are tied to a good earth ground, either through the line cord grounding pin or
the rack screws to another grounded chassis.
3. Units with outboard power supplies do
not
ground the chassis through their line cords. Make sure these units are grounded either
to another chassis which is earth grounded, or directly to the grounding screw on an AC outlet cover by means of a wire con-
nected to a screw on the chassis with a star washer to guarantee proper contact.
