ULX-D Digital Wireless Microphone System
Radio Frequency (RF)
RF LEDs
If neither blue RF Diversity LED is illuminated, then the receiver is not detect-
ing the presence of a transmitter.
The amber RF Signal Strength LEDs indicate the amount of signal being re-
ceived. This signal could be from the transmitter, or it could be from an in-
terfering source, such as a television broadcast. If more than one or two
of the amber RF LEDs are still illuminated while the transmitter is off, then
that channel has too much interference, and you should try a different channel.
The red RF LED indicates RF overload. This will usually not cause a problem
unless you are using more than one system at the same time, in which case,
it can cause interference in the other system.
Compatibility
•
Perform a Scan and Sync to ensure the transmitter and receiver are set
to the same group and channel.
•
Look at the label on the transmitter and receiver to make sure they are
in the same band (G50, J50, L50, etc...).
Reducing Interference
•
Perform a group or channel scan to find the best open frequency. Perform
a sync to transfer the setting to the transmitter.

•
For multiple systems, check that all systems are set to channels in the
same group (systems in different bands do not need to be set to the
same group).
•
Maintain a line of sight between transmitter and receiver antennas.
•
Move receiver antennas away from metal objects or other sources of RF
interference (such as CD players, computers, digital effects, network
switches, network cables and Personal Stereo Monitor (PSM) wireless
systems).
•
Eliminate RF overload (see below).
Increasing Range
If the transmitter is more than 6 to 60 m (20 to 200 ft) from the receiver an-
tenna, you may be able to increase range by doing one of the following:
•
Reduce interference (see above).
•
Increase transmitter RF power level.
•
Use an active directional antenna, antenna distribution system, or other
antenna accessory to increase RF range.
Eliminating RF Overload
If you see the red RF LED on a receiver, try the following:
•
Reduce the transmitter RF power level
•
Move the transmitter further away from the receiver—at least 6 m (20 ft)
•
If you are using active antennas, reduce antenna or amplifier gain.
•
Use omnidirectional antennas
