Analog Loop Design Considerations

4.7 NOISE CONSIDERATIONS
Although the MXP loop has been designed for minimum electrical interference, it is still
capable of both picking up and generating electrical interference. The longer the loop the
greater the potential problems. Each analogue loop must be considered on its own merits,
taking into account possible noise sources along the loop's proposed routing. Normal
engineering practice applies, such as keeping the loop wiring separate from other wiring,
especially power cables, speaker cables, leaky coaxial cable and noise sensitive cables for
audio systems.
In extreme cases it may be necessary to implement the analogue loop as a screened pair,
with the screen connected to the metal case at the MXP only.
