Pre-coordinated Frequencies
Intermodulation interference is a problem constantly
lurking in the background, especially when working
in environments where simultaneous productions are
taking place in close proximity. In these cases, proper
frequency coordination is a must. There are basically
three methods to coordinate frequencies:
• Use the built-in frequency groups
• Scan for clear channels (See SmartTune ™
and Scan Function.)
• Call Lectrosonics
Frequency Compatibility Chart
Considering that multiple systems can be used in a produc­
tion, coordinating frequencies to minimize interference
between these channels can be a daunting process.
The Frequency Compatibility Chart was designed to as­
sist in minimizing intermodulation problems for multiple
channel wireless systems. It does this by identifying
potential intermodulation problems and listing compat­
ible frequencies and frequency groups. This chart can
be used with all Digital Hybrid Wireless ™ (400 Series)
receivers.
The chart divides the frequency blocks used in the North
American market into Set 1 and Set 2, then further di­
vides each row into two groups of eight frequencies each.
Note: The term “Set” as used here is for
clarification only. The firmware does not make
reference to “Sets”, only “Groups.”
These frequency groups are labeled A and B and C and
D, and correspond to the factory set frequency groups
(Groups A, B, C and D) described in the Tuning Setup
Screen.
Understanding and using the Frequency Compatibility
Chart is not as difficult as it first appears. There is a pat­
tern of compatible frequencies that becomes apparent, as
illustrated on the Frequency Compatibility Diagram on the
next page.
