Procedure for Reusing the Same Frequency 1/2
When using transmitters in numbers greater than the number of simultaneously
usable channels and in close proximity to each other, microphones operating on the
same frequency can be used simultaneously by utilizing their digital characteristics.
Note, however, that the same frequency cannot be used in the same room.
1. Make channel plans
1) Referring to the Frequency Table, select an arbitrary bank from A to F.
2) Scan receiver channels.
• C band: Searches for channels in two banks including the currently-set bank and displays idle channels.
Combinations of scanned banks are as follows:
When Bank A or B is currently set a Searches for and displays idle channels in Banks A and B.
When Bank C or D is currently set a Searches for and displays idle channels in Banks C and D.
When Bank E or F is currently set a Searches for and displays idle channels in Banks E and F.
• G band: Searches for all bank channels in the dedicated digital plan, and displays idle channels.
3) Assign idle channels to multiple rooms as shown in the following examples to prevent channels
operating on the same frequency from being too close to each other.

[Example] Same floor or same location on each floor.
[Example] Multiple rooms are adjacent to each other on both upper and lower floors in facilities like rental
conference rooms and schools. There is a high possibility that the frequencies being used in the
room may also be able to be used in rooms .
‐ Keep channels using the same frequency as far away from each other as possible.
If used on the same floor, keep them at least two rooms apart.
‐ Set the wireless microphone’s transmission output to “L.”
‐ Adjust the antenna attenuator.
