(27) POWER:

Switches the transmitter “ON” or “OFF”.

(28) LCD Display:

This display shows the following information:

TV:Transmit Channel Number: 30:01 – 33:47

Battery Condition: Using a 3 step indicator - 1 (Low) to 3 (High)

To change the TV:Transmit channel number: Use the tip of the tool provided and press the

UP or DOWN button to the desired channel, number appears (refer to the included chart).

Once the desired TV:Transmit channel number has been selected on the transmitter, set the receiver to the same number.

The TV:Transmit channel display is made of two parts. The first number is the actual TV channel (30-33) and the second is the “transmit channel” number (01-47).

Operating the system: Because this is a frequency agile system, the receiver and transmitters must be on the same channel number. To change the channel number, use the tip of the provided tool and press the UP or DOWN button to the desired channel. Make sure both the receiver and transmitters are on the same channel. Remember that each transmitter must be on a different channel.

325UPR 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 325UPR to “ON” and the battery level indicator(s) should come on. If they do not, check the batteries. When the 325UPR 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.

35BT 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 35BT 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.

35XT Transmitter: Switch the transmitter 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 camera’s monitor output. If the sound is distorted, lower the level control on the transmitter.

If there is not enough gain, raise the level control on the transmitter.

35HT Transmitter: Switch the transmitter 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 camera’s monitor output. If the sound is distorted, lower the level control on the transmitter.

If there is not enough gain, raise the level control on the transmitter.

Thank you for purchasing Azden’s 325 wireless microphone system. Depending on which system you ordered this package will contain one or more of the following components: the 325UPR receiver, the 35BT body-pack transmitter with EX-503L lavalier microphone, the 35XT XLR plug-in transmitter and/or the 35HT handheld microphone transmitter. This equipment is designed primarily for video cameras but is usable with most electronic components having a microphone level input. The 325UPR allows you to

“receive” audio from two different transmitters at the same time.

RECEIVER (325UPR)

Note: When using two transmitters with the 325UPR please do the following:

A) 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 TV:Receive channel number 30:10 for one transmitter, use channel number 30:20 for the other transmitter. The 2 channels on the receiver must also be set on the numbers 30:10 and 30:20.

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.
