Pre-Coordinated Frequencies; Compatible Frequency Table - Lectronics Wideband Installation Manual

Venue Wideband Receiver

Pre-coordinated Frequencies

Interference from IM (intermodulation) is a potential
problem in all multi-channel wireless systems, so proper
frequency coordination is always required to avoid
noise, range and dropout problems. Your options to ac-
complish this include:
• Using the pre-coordinated frequency groups
• Performing a system checkout
(See Multi-channel System Checkout)
• Calling Lectrosonics for assistance

Compatible Frequency Table

Groupings of compatible frequencies have been cre-
ated to minimize intermodulation problems in multiple
channel wireless systems. The frequencies can be used
with Digital Hybrid and analog Lectrosonics wireless
equipment. Compatibility with other brands is likely, but
not guaranteed by Lectrosonics.
The table provides two different sets of pre-coordinated
frequencies for frequency blocks 470 through 29. The
table is constructed to create a visual pattern of com-
patible frequencies to make it easier to use. The fre-
quencies are stored in memory in various products and
included in the VRpanel software.
26
Pre-coordinated fre-
quencies are arranged
in four groups as shown
at right.
The uppermost eight
frequencies comprise
Grp a, the eight just
below them comprise
Grp b, and so on.
Example: Frequencies by Block, Frequencies will vary by block.
