Ground Loop Control

Powering Up

4.5 Ground Loop

Control

Strict adherence to the wiring conventions noted above within a fully

balanced signal system will yield the best possible results with none of

the problems normally associated with interconnected audio equipment.

Wherever possible, cable screens should not be connected to any signal

pin, but rather left to perform a cable shielding function only.

Where it is not possible to control all of the external cabling, it might

become necessary to have the internal electronic ground of your unit

separated from the case safety ground. Provision is made internally

within the FCS-930/960 to separate these two grounds at a convenient

point, or to add a suitable impedance network as part of a house system

requirement.

Please refer to a later section for information on this procedure.6.

Under no circumstances should the safety ground wire be removed

from the mains AC power connector as an interim measure to achieve

similar results.

When the FCS-930/960 is switched on by operating the power on-off

switch located on the rear panel, the front panel LED showing the

normal MODE will be illuminated. This indicates to you that the internal

power supply circuitry is functioning correctly. The unit will also be in

it’s bypass mode. Should you subsequently have the EQ IN switch

selected before power up, there will be a slight delay before the bypass

relays operate to allow time for the internal circuitry to settle down. This

ensures a silent power up without danger of causing damage to other

equipment connected to the unit’s outputs.
