27 EMC Considerations
The Cloud Z4 & Z8 fully conform to the relevant electromagnetic compatibility (EMC)
standards and are technically well behaved; you should experience no operational problems
and under normal circumstances, no special precautions need to be taken. If the unit is to be
used within close proximity to potential sources of HF disturbance such as high power
communications transmitters, radar stations and the like, the performance of the mixer may
be reduced; we suggest that the microphone cable screen be connected to the shell of the
XLR type connector and the line input leads are kept as short as possible.
