Fig. 7 MSR Grounding
In any multi-channel audio system where low level signals are being
routed, it is important to ensure a consistent and positive earthing
system to minimise any possible noise interference and hum loops.
With the use of microphones it is especially important to ensure reliable
earthing and screening not only for these noise considerations but also
for safety of the performers.
Figure 7 shows the internal grounding arrangements for the MSR-602 II
and MSR-604 II, and figure 8 shows one of the common earth and
grounding arrangements for a complete MSR-600 system, where the
microphone shielding is held directly to ground.
The star grounding point is the main ‘front of house’ mixing console, and
this earth is the one used to shield all cables and the microphone body.
There should be no connection between this earth and that of the MSR-
604 II chassis, and the system ground switch on the MSR-602 II rear
panel should be set to ‘lifted’.
All the metal casing associated with the MSR-600 II system will be
grounded via the MSR-602 II power cord, and through a separate
conductor within the DC power lead to the MSR-604 II units. The
electronic 0v ground will be connected to the main front of house
mixing console earth system via the interconnecting audio cables.
