OPERATING RANGE
Each transmitter has a normal operating range of 150 ft. (45.7 m), and 300 ft. (91.4 m)
in optimum conditions.
An intermittent or weak signal can be an indication that you have reached the
maximum operating distance. The operating range can change depending factors
such as weather, atmospheric conditions, terrain, obstructions, and battery power.
If you notice signal intermittence, dropouts, or decreased volume.
1. Move the transmitters closer to the receiver.
2. Eliminate obstructions to the line of sight between transmitters and receiver.
3. Check the battery power in the transmitters and receiver. If the battery power is low, replace or fully recharge
the batteries.
12
INTERFERENCE
Radio Frequency (RF) or Electromagnetic (EM) interference can cause buzzing or humming, noise bursts, pops,
clicks, and dropouts.
The channel status indicator shows whether a channel is usable, or if it has interference that can affect your audio.
See
Finding an Interference-Free Channel
below.
If the channel status indicator shows channel interference, or if interference develops while the system is in use,
change the transmitters and receiver channel:
Important! The transmitters and the receiver must all be set to the same channel.
To avoid interference:
1. Turn off smartphones, walkie talkies, and computers in the area.
2. Try to avoid areas where there are high-voltage power cables for lighting and sound equipment.
3. Improve the line of sight between the transmitters and the receiver.
4. If the receiver is inside a metal equipment rack, move it a location where it isn’t surrounded by metal.
Play/pause, volume control, and forward and back track selection can be controlled from the front panel or from
the remote.

Ideally, the reception should be at full strength. To remedy a weak signal, see
Setting Signal Strength
below.
Audio Level
Each transmitter signal has an audio meter. The level of the transmitter signal should be strong enough to record
audio accurately and without distortion or dropouts.
17
The audio level should be as high as possible without peaking. If the meter rises to the top due to intermittent
loud noises or vocal plosives like P and B sounds, it could distort the audio. To remedy peaking audio, see
Setting Mic/Line Level Input
and
Setting Input Volume (Gain)
below.
OPERATING THE TRANSMITTER
Setting Signal Strength
The transmitter has a selectable high and low RF transmission power
setting.
L (Low, 15 mW) is ideal when the transmitter is close to the receiver.
It also provides the transmitter with approximately 20% more run time.
H (High, 25 mW) transmits a stronger signal, and allows the microphone
to cover a wider area and more range. This setting is recommended if your subject is moving around or is
consistently more than 200 feet from the receiver. This setting is also recommended if you’re recording in an area
with heavy RF interference.
18

Problem Solution
The audio is noisy or
distorted. This can
include dropouts,
white noise, bursts,
pops, and clicks.
• Noise might be caused by RF interference. Try a different channel. Make sure both units are on the same
channel.
• There can be a lot of RF interference outdoors. Try moving indoors, where there is less RF interference.
• Keep the units’ antennas at least 2 feet (0.6 m) away from conductive objects like metal and water.
Overhead telephone lines, fluorescent lighting, and metal fences can all cause interference.
• Turn off all nearby computers and mobile phones.
• Test your RF environment before recording. To do this, turn on the receiver. If there is noise from interference
on the channel, the channel indicator will show BUSY, and you should avoid using it.
• Noise can also be caused by receiver overload. If the antennas are too close, it can cause receiver overload
(intermodulation). Make sure the antennas are at least 3 feet (0.9 m) away from each other.
• You may be experiencing a weak signal. Make sure there is an unobstructed line of sight between the
receiver’s and the transmitter’s antennas. Keep in mind that your body, wardrobe, and onstage sets are
possible obstructions. Make sure the receiver and transmitter are within the 300-foot (100 m) range. If
there are obstructions, you may need to move closer.
The receiver is
getting sound from
only one channel.
• Set both transmitters and the receiver to the same channel.
• Set the transmitter volume to a higher output level.
• Make sure the transmitter is within range of the receivers.
• Make sure one transmitter is set to transmitter channel A, and the other is set to transmitter channel B.
TROUBLESHOOTING
30
Problem Solution
The input level on
the camera, recorder,
or mixer is too high.
• Turn down the audio input level on your camera or recording device.
• Decrease the receiver’s output level.
• Make sure the output of the receiver is plugged into the line-level input on your mixer, or that the line/mic
switch on your mixer is set to line.
• Turn down the gain on your mixer.
• Adjust the output volume on the transmitter, but keep this level as high as possible without distortion.
There is no audio.
• Make sure the transmitter’s mute button is not active.
• Check all cables to make sure they are completely plugged into the proper inputs.
• If you are transmitting a line-level signal, make sure there is audio coming out of the line-source device.
• If you want to record via the microphone input, make sure there is nothing plugged into the transmitter’s
line-level input.
• If there is no sound in the headphones, make sure the headphones are completely plugged into the
headphone jack. Increase the receiver’s output level.
• Make sure the transmitter and receiver are set to the same channel.
• Make sure the receiver is receiving signal from the transmitters, and the transmitter indicators are not
blinking.
31
Problem Solution
Too much ambience
is being picked up.
• If you’re using an omnidirectional microphone, the microphone may be picking up too much ambience or
room noise.
• Make sure the microphone is as close as possible to the subject. Approximately 6 inches (15.2 cm) from the
subject is usually good microphone placement, but you may need to experiment.
• Reduce acoustic reflections in the area by hanging an acoustic blanket, acoustic foam, fabric, or rug over
bare walls, floors, and windows.
Too much low-
frequency noise and
rumble are being
picked up.
• Activate the low-cut filter on the transmitter.
• Make sure the foam windscreen is on the lavalier microphone to minimize wind noise.
• Turn off nearby fans or air conditioning units.
