COMMON ANALOGUE GROUNDING
ISSUES
Correctly connecting the IndustryAmp to ground has
several benefits. A full discussion of the issues involved can
be found at
;
Basic points to observe are:
1. Safety.
The GND terminal of the PowerCon
®
mains
connector provides a direct low impedance path from the
metal parts of the chassis to ground. Always connect this
terminal.
2. Reduction of RF emission.
Although the IndustryAmp
electronics are well shielded and external connections are
decoupled to prevent RF emission from the internal high
speed digital circuits, this protection will not work properly
if the chassis is not connected to ground.
3. RF Immunity.
RF currents induced in the signal cables by
external RF fields are effectively shorted to chassis ground,
provided that the cable screen (shield) is of sufficiently low
impedance.
The pins with a symbol on the audio line input
connectors and the ambient SPL mic connector are
connected internally directly to the chassis of the amplifier.
These pins are for connecting the screen (shield) of the
audio cables.
