CHASSIS GROUNDING
If your system exhibits excessive hum or buzzing, there is an incompatibility in the grounding configuration between units some-
where. Here are some things to try:
1. Check that the turntable grounding wires are connected to the PHONO GND posts.
2. Try combinations of lifting grounds on units that are supplied with ground lift switches or links.
3. 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, or tied to the ground screw located next to the POWER switch.
4. This unit’s outboard power supply does not ground the chassis through the line cord. Make sure that this unit is 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 connected to a
screw on the chassis with a star washer to guarantee proper contact.
Please refer to the RaneNote, “Sound System Interconnection” (supplied with this manual and available on our website) for further
information on system grounding.
