Frequently Asked Questions - 310XT Azden

What batteries does the Azden 310XT use and how long do they last?

Both the receiver and transmitter use two AA alkaline batteries, providing 6-8 hours of runtime. Rechargeable Ni-MH AA batteries can also be used. Ensure correct polarity when inserting.

How do I change the channel on the 310XT system?

Using a small pointed object (like a pen tip), press the UP/DOWN buttons on the receiver and transmitter to select the same channel number. Channels are displayed as TV channel (30-33) and transmit channel (01-47). Both units must be on the same channel.

Can I use my own microphone with the 35XT transmitter?

Yes, the 35XT has a 3-pin XLR connector for low-impedance microphones. Simply plug in any compatible microphone and tighten the locking ring clockwise.

How do I adjust the audio level on the transmitter?

Open the battery compartment to access the orange MIC LEVEL dial. Turn clockwise to increase input level, counterclockwise to decrease. Use the supplied tool or a small screwdriver.

What does the AUDIO switch on the transmitter do?

The AUDIO switch acts as a mute. Set it to OFF before turning the power ON. When ready to transmit, set it to ON. The OFF position keeps the RF signal active but mutes audio.

Why is my receiver not showing a signal?

Ensure both receiver and transmitter are set to the same channel. Check that fresh batteries are installed correctly and the transmitter is powered on. Verify the antennas on the receiver are pointed upward. Also, ensure the AUDIO switch on the transmitter is ON if you want audio.

What cables are included with the 310XT?

The kit includes a stereo mini-to-stereo mini cable and a stereo mini-to-dual XLR cable. Use the mini-to-mini for cameras with a 3.5mm mic input, or the mini-to-XLR for cameras with dual XLR inputs.

Can I use rechargeable batteries?

Yes, you can use AA Ni-MH rechargeable batteries (e.g., Azden 1HR-3U). Note that runtime may be slightly less than alkaline.

How do I clean and maintain the 310XT system?

Keep the units dry and store in a cool place. Remove batteries if not used for long periods. Wipe with a soft dry cloth. Do not submerge or use solvents.

Is the 310XT compatible with my DSLR camera?

Yes, the 310UDR receiver connects to cameras with a 3.5mm microphone input or dual XLR inputs using the supplied cables. It is widely compatible with DSLRs, camcorders, and audio recorders.

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
