Guidance on the use of a multi-channel system using digital wireless system
When building up the system with digital wireless devices only, channel intervals can be fixed. No special calculations are necessary
to avoid intermodulations. Set channel intervals to 375 kHz or more.
When building up a multi-channel system, Sony recommends that one of the following groups is selected to avoid mutual interference
from other Sony wireless microphones/transmitters:
– Groups D1 to D4 are for using 12 channels of transmitting frequencies in one TV channel.
– Groups D5 to D8 are for using 24 channels of transmitting frequencies in two TV channels.
– Group D9 is for using 48 channels of transmitting frequencies in four TV channels.
