Frequently Asked Questions - 330LX Azden

How do I pair the transmitter with the receiver?

Turn on the receiver and transmitter. The system should automatically sync. If not, press the 'SET' button on the receiver to scan for the transmitter signal. Refer to the manual for detailed pairing steps.

What type of batteries does the transmitter use?

The transmitter uses two AA alkaline batteries. For best performance, use fresh batteries and replace them when the low-battery indicator appears.

How can I reduce interference from other wireless devices?

Change the channel using the receiver's channel selection feature. Avoid using multiple wireless systems on the same frequency. Keep the transmitter and receiver at least 10 feet apart from other electronic devices.

What is the operating range of the Azden 330LX?

The typical operating range is up to 300 feet (90 meters) in open line-of-sight conditions. Walls and obstacles may reduce the range.

Can I use multiple Azden 330LX systems together?

Yes, but you must assign different channels to each system to avoid interference. The receiver allows manual channel selection. Ensure frequencies do not overlap.

How do I clean the microphone and receiver?

Use a soft, dry cloth to wipe the exterior. Do not use chemical cleaners or water. For the microphone grille, gently brush away dust.

The audio is distorted or has low output. What should I do?

Check the transmitter battery level. Ensure the microphone capsule is securely attached and not blocked. Adjust the gain control on the receiver if available. Also check cables and connections.

Does the Azden 330LX come with a warranty?

Yes, Azden typically offers a one-year limited warranty against defects in materials and workmanship. Keep your purchase receipt for warranty service.

Can I use a different microphone capsule with the transmitter?

Yes, the transmitter is compatible with standard Azden microphone capsules. Ensure the connector matches (usually a 3-pin mini XLR). Refer to the specifications.

How do I reset the receiver to factory settings?

Press and hold the 'SET' button while turning on the receiver. The display will indicate a reset. Release the button. This clears all channel settings.

Operating the System

WARNING

• Do not use other batteries than the ones specified in this manual. Do not mix fresh battery with a used battery.
• When installing batteries, make sure battery polarity is correct as marked inside the battery compartment.
• Remove the batteries if the products are not used for a long period of time.
• Do not submerge the products.

Because this is a frequency agile system, the receiver and transmitter must be on the same channel number. To change the channel selection, use the tip of the provided tool and press the “UP” or “DOWN” button to the desired channel. Make sure both the receiver and transmitter are on the same channel.

330UPR Dual-Channel Receiver

After installing new batteries, mount the receiver to your video camera with supplied shoe mount or hook & loop fastener. Select one of the supplied cables and connect the output on the receiver and input on the video camera. Turn the power switch for Ch. 1 and/or Ch. 2 to “ON” and the battery level indicator on the LCD display should come on. If not, check the batteries. When the 330UPR receives a signal from the transmitter, the reception level indicator will come on. If it does not, make sure both the receiver and the transmitter are on matching channels.

35BT Body-Pack Transmitter

Plug in the supplied EX-503L Lavalier Microphone and clip it to your subject. The microphones should be placed 4"-12" from the subject's mouth. Clip the transmitter to a belt by using the supplied belt clip or place it in a pocket. Turn the power switch to "ON" and the battery level indicator on the LCD display should come on. If not, check the battery. Have someone speak into the microphone as you monitor the sound through the 330UPR Receiver's phone output. If the sound is distorted, lower the MIC input level on the 35BT Transmitter. If there is not enough volume, raise the MIC input level on the Transmitter.

35XT Plug-in Transmitter

Attach the 35XT Transmitter to any low impedance microphone with a corresponding 3-pin XLR connector. Turn the power switch on the 35XT Transmitter to “ON” position and the battery level indicator on the LCD display should come on. Have someone speak into the microphone as you monitor the sound through the camera’s monitor output. If the sound is distorted, lower the MIC input level control on the 35XT Transmitter. If there is not enough volume, raise the level control on the Transmitter.

35HT Handheld Microphone/Transmitter

Turn the power switch on the 35HT Transmitter to “ON” position and the battery level indicator on the LCD display should come on. Have someone speak into the microphone as you monitor the sound through the camera’s monitor output. Adjust the MIC input level control accordingly.

330UPR Dual-Channel Receiver

①Antennas

For the best reception, the antennas should be pointed in an upward position. Use caution and do not force them into this position.

②Power Switch for each Channel

A separate Power Switch for Channel 1 and 2.

③Universal LCD Display for Ch. 1 and 2

The LCD Display shows multifunctional readout and can be switched between the channels by pressing the DISP 1/2 Button (5). Refer to “LCD Display Readouts” in this manual for further details.

④CHANNEL UP and DOWN Button

To change the channel number, use a small, sharp object, such as the tip of a pen, and press the UP or DOWN button until the desired channel number is shown on the LCD Display. Keep the button pressed down to fast forward the channel numbers. Once the desired channel number is selected on the receiver, set the transmitter to the same number.

⑤DISP 1/2 Button

Press to switch the LCD Display between Ch. 1 and 2.

⑥LCD Display MODE Switching Button

Press to switch the LCD Display to show the actual frequency number in MHz being used on each channel.

⑦PHONE Jack

⑧MIC OUT Jack

The 330UPR is supplied with both mini-to-mini and mini-to-dual XLR cables.

For mini jack microphone inputs: Use the supplied mini-to-mini cable. Plug one end of the cable into the 330UPR Receiver and the other end into the microphone input of the video camera.

For 3-pin XLR microphone inputs: Use the supplied mini-to-dual XLR cable. Plug the mini-plug end of the cable into the 330UPR Receiver (use the screw-down sleeve to secure it to the receiver) and plug the XLR ends into the microphone inputs on the video camera. Ch. 1 is on the “Tip” and Ch. 2 on the “Ring”.

⑨Battery Compartment

Remove the battery compartment lid by sliding it down. Install two fresh alkaline “AA” batteries. Make sure the battery polarity is correct as marked inside the battery compartment. Alkaline batteries are preferred, but Azden’s 1HR-3U rechargeable Ni-MH batteries may be used.
