320UPR Receiver
After installing new batteries, mount the receiver to your video camera with the supplied
shoe mount or hook & loop fastener. Select one of the supplied cables and connect the
output cable to the receiver and to the microphone input on the video camera. Switch Ch.1
and/or Ch.2 of the 320UPR to “ON” and the battery level indicator(s) should come on. If
they do not, check the batteries. When the 320UPR receives a signal from the transmitter

the reception level indicator will come on. If it does not, make sure both the receiver and
transmitters are on matching channels.
30BT Transmitter
Plug in the supplied lapel microphone and clip it to your subject. The microphone should be

placed 4-12 inches from your subject’s mouth. Clip the transmitter to a belt using the
supplied belt-clip or place it in a pocket. Switch the 30BT to “ON” and the battery level
indicator should come on. If it does not, check the battery. Have someone speak into the
microphone as you monitor the sound through the receiver’s phone output. If the sound is
distorted lower the MIC input level on the transmitter. If there is not enough volume raise the
MIC input level on the transmitter.

following information.
Thank you for purchasing Azden’s 320 wireless microphone system. Depending on
which system you ordered this package will contain one or more of the following components: the 320UPR receiver, the 30BT body-pack transmitter with EX-503L lavalier microphone, the 30XT XLR plug-in transmitter and/or the 30HT handheld microphone
Channels number: 001 to 240
Battery Condition: Using a 3 step indicator – 1(Low) to 3 (High)
transmitter. This equipment is designed primarily for video cameras but is usable with
most electronic components having a microphone level input. The 320UPR allows you to
“receive” audio from two different transmitters simultaneously.
To change the channel number, use the tip of the tool provided and press the UP or DOWN
button until the desired channel number appears (001 to 240). Once the desired channel
number has been selected on the transmitter, set the receiver to the same channel number.
RECEIVER (320UPR)
HANDHELD MICROPHONE/TRANSMITTER (30HT)
(22) Remove the battery compartment cover by rotating it counterclockwise and sliding it
down.
(23) Insert two fresh Alkaline “AA” batteries into the compartment. Make sure the battery
polarity is correct as marked inside the battery compartment.

(2) Insert two fresh alkaline “AA” batteries into the compartment. Make sure the battery
polarity is correct as marked inside the battery compartment.
(3) POWER (one switch for each channel)
Switches the receiver CH1 and/or CH2 “ON” or “OFF”.
(4) MIC OUT jack:
In the battery compartment you will also find:
The 320UPR is supplied with both a mini-to-mini and a mini-to-dual XLR cable.
(24) MIC LEVEL Control
The MIC LEVEL control enables you to adjust the audio level of the microphone. Using the
supplied tool, turn the dial clockwise to increase, or counterclockwise to decrease the
microphone’s audio level.
For mini jack microphone inputs: Use the supplied mini-to-mini cable. Plug one
end of the cable into the receiver and the other end of the cable into the microphone input of the video camera.
For 3-pin XLR microphone inputs: Use the supplied mini-to-dual XLR cable. Plug
(25) UP/DOWN Channel Buttons
To change the channel number, use the tip of the tool provided and press the UP or DOWN
button until the desired channel number appears (001 to 240). Once the desired channel
number has been selected on the transmitter, set the receiver to the same channel number.
the mini-plug end of the cable into the receiver (use the screw-down sleeve to secure it to the receiver) and plug the XLR ends of the cable into the microphone
inputs of the video camera. Ch.1 is on the “Tip” connector, Ch.2 is on the “Ring”.
(5) LCD Display:
(26) POWER
Switches the transmitter “ON” or “OFF”.
(27) LCD Display:
The display will light up when the power is turned “ON”. The LCD display shows the
following information.
Channel number: 001 to 240.
Battery Condition: Using a 3 step indicator - 1 (Low) to 3 (High)
There are two displays, one for CH1 and one for CH2. The display for each channel will
light up when the power for that channel is turned “ON”. The LCD displays show the
following identical information.
Channel Number: 001 to 240
Battery Condition: Using a 3-step indicator - 1 (Low) to 3 (High)
Reception Level: Using a 4-step indicator - 1 (Low) to 4 (High)
To change the channel number, use the tip of the tool provided and press the UP or
DOWN button until the desired channel number appears ( 001 to 240). Once the desired
channel number has been selected on the receiver, set the transmitter to the same
channel number.
NOTE: When using two transmitters with the 320UPR please do the following:

) Make sure that you use 2 different channel numbers that are at least 10 numbers
apart. This will prevent possible crosstalk between the 2 channels being used. For example: If you use channel number 10 for one transmitter, use channel number 20 for the
other transmitter. The 2 channels on the receiver must also be set on the numbers 10
and 20.
B) The system will operate properly if both transmitters are in close proximity to each
other, however make sure that both transmitters are at least 10 feet away from the receiver, this will prevent the frequencies from overlapping.
(6) PHONE jack:
Plug a stereo headphone into this jack to monitor sound - Ch. 1 will be heard on the left,
Ch. 2 on the right.
(7) DC 6 Volt Input: An optional charger/power supply and rechargeable batteries are
available for the 320UPR. For additional information or to order these products please
visit the Azden website at www.azdencorp.com
NOTE: Using a power supply of the wrong voltage/current may damage the unit
and void the warranty.
(8) Shoe Stand:
ttach the 320UPR to the shoe-mount of the video camera by sliding it into place. Turn
the thumbwheel clockwise to tighten. Reverse this procedure to remove the 320UPR
from the camera.
(9) Antennas: For best reception the antennas should be pointed in an upward fashion.
Use caution, and do not force them into this position.
or contact your Azden dealer.
BODYPACK TRANSMITTER (30BT)
(10) Remove the battery compartment lid by sliding it down.
(11) Insert two fresh “AA” batteries* into the compartment. Make sure the battery polarity
is correct as marked inside the battery compartment.
In addition to the battery, inside the battery compartment you will find:
(12) MIC Input LEVEL Control
This control enables you to adjust the input level of the microphone. Using the supplied
tool, turn the dial clockwise to increase, or counterclockwise to decrease the input level.
(14) MIC Input Jack
Plug the supplied EX-503L microphone into the MIC input jack and tighten the collar until
snug (DO NOT OVERTIGHTEN). In addition to the EX-503L, other lapel and/or headset
microphones with 3.5mm mini plugs can also be used with the 30BT.
(15) LCD Display
This display shows the following information.
Channel Number: 001 to 240
Battery Condition: Using a 3 step indicator - 1 (Low) to 3 (High)
To change the channel number: Use the tip of the tool provided and press the UP or
DOWN button to the desired channel, number appears (001 to 240). Once the desired
channel number has been selected on the transmitter, set the receiver to the same
channel number.
*While Alkaline batteries are preferred, you can use rechargeable Ni-Cd or Ni-MH batteries.
XLR PLUG-IN TRANSMITTER (30XT)
(16) Open the battery compartment lid by sliding it down and lifting it up.
Insert a 9 volt Alkaline battery into the compartment. Make sure the battery polarity is correct as marked inside the battery compartment.
(17) POWER
Switches the transmitter “ON” or “OFF”.
(18) AUDIO
Prior to first turning the 30XT “ON” it is best to set the AUDIO switch to “OFF”. When
you are ready to begin transmitting, switch to “ON”. The “OFF” position acts as a
“mute” that maintains the RF signal but turns off the audio.
(19) MIC Connector/Locking Ring
This 3-pin XLR connector is the microphone input. Any low impedance microphone
with a corresponding connector can be attached here.
Once the microphone is plugged into the 30XT the locking ring should be rotated clockwise until snug. To remove the microphone, first rotate the locking
ring counterclockwise and then, while pressing the XLR release, pull the microphone away from the 30XT.
(13) POWER
Switches the transmitter “ON” or “OFF”.
