Frequently Asked Questions - 310LH Azden

How do I set the channel on the Azden 310 system?

Use a small pointed object like a pen tip to press the UP or DOWN button on both the receiver and transmitter. Ensure both are set to the same channel number (01-47) for proper operation.

What type of batteries does the Azden 310 use?

Each unit (receiver, body-pack, handheld, plug-in transmitter) uses 2 AA alkaline batteries. Rechargeable Ni-MH batteries (Azden 1HR-3U) can also be used.

How long do the batteries last?

Typical battery life is 6-8 hours with fresh alkaline batteries.

Can I use other microphones with the 35BT body-pack?

Yes, any lavalier or headset microphone with a 3.5mm mini plug can be used with the 35BT body-pack transmitter.

What does the AUDIO switch do on the transmitters?

The AUDIO switch acts as a mute. Set it to OFF before powering on, then turn to ON to transmit audio. The RF signal stays on, allowing you to mute audio without losing connection.

How do I adjust the microphone input level?

Use the supplied tool to turn the orange dial inside the battery compartment. Clockwise increases level, counterclockwise decreases. Listen for distortion or low volume.

Why is there no sound from the receiver?

Check that both receiver and transmitter are on the same channel. Ensure the transmitter's AUDIO switch is ON, the microphone is properly connected, and the receiver is connected to the camera. Also check battery levels.

Can I use the Azden 310 with a mixer or audio interface?

Yes, connect the receiver's mini jack output to the mixer's microphone input using the supplied cables. The receiver provides microphone-level output.

How do I mount the receiver to a camera?

Use the supplied shoe mount to attach the receiver to the camera's hot shoe, or use the hook-and-loop fastener to secure it to the camera body.

What should I do if the receiver displays no reception bars?

Ensure the transmitter is powered on and set to the same channel as the receiver. Move the transmitter closer to the receiver. Check that antennas on the receiver are pointed upward. Also verify batteries are fresh.

Operating the System

WARNING

• Do not use other batteries than the ones specified in this manual. Do not mix a 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 a small , sharp object such as the tip of a pen, and press the "UP" or "DOWN" button to the desired channel. Make sure both the receiver and transmitter are on the same channel.

310UDR Diversity 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 to "ON" and the battery level indicator on the LCD display should come on. If not, check the batteries. When the 310UDR 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 310UDR 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.

310UPR Diversity Receiver

① Antennas

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

② Power Switch

To turn ON/OFF the receiver

③ LCD Display

The LCD Display shows multifunctional readout. Refer to “LCD Display Readouts” in this manual for further details.

④ CHANNEL 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.

⑤ PHONE Jack

This jack allows you to monitor the sound.

⑥ MIC OUT Jack

The 310UDR is supplied with both mini-to-mini and mini-to-dual XLR cables.
