How to Set up Interference-free
Compatible Systems for ACT-747 Receivers?
-
For up to 8 compatible systems ( 8 channels can be operated
together ) : The manufacturer recommends in using all the 8
factory preset channels found in groups 1, 2, 3, 4, 5 or 6.
1 meter minimum safe distance is needed between the
transmitters and the receivers for operation.
-
For up to 12 compatible systems ( 12 channels can be
operated together ) : The manufacturer recommends in using
all the 12 factory preset channels found in groups 7 or 8.
1.5 meters minimum safe distance is needed between the
transmitters and the receivers for operation.
-
For up to 16 compatible systems ( 16 channels can be
operated together ) : The manufacturer recommends in using
all the 16 factory preset channels found in groups 9 or 10.
3 meters minimum safe distance is needed between the
transmitters and the receivers for operation.
-
For up to 32 compatible systems ( 32 channels can be
operated together ) : Factory preset channels in groups of
two different frequency bands are needed.
-
To set up multi-channel operation, the user must select
factory preset channels within the same group. A combination
of preset channels under different groups can result in
possible interference.
-
When preset channels ( Channels 1,2,3, etc. ) within the
same group experience interference and cannot work together,
it is highly recommended to change to another set of preset
channels in a different group.
-
If interference persists in all groups within the chosen
frequency band, changing to another frequency band may be
recommended.
NOTE：
The factory preset interference-free channels are
designed for MIPRO ACT receivers only.
Do not mix and use simultaneously with wireless microphone
systems from other brands.
