1. Introduction
The AZDEN CAM-3 is a compact, passive mini audio mixer designed to enhance the audio capabilities of your camcorder. It allows you to connect and mix sound from up to three separate microphone sources simultaneously, providing independent volume control for each channel. This device operates without the need for batteries, drawing power passively from the connected microphones or camcorder input, making it a convenient and portable solution for field recording.
2. Safety Information
Please read and understand the following safety guidelines before using the AZDEN CAM-3 Mini Audio Mixer:
- Proper Use: Use the mixer only for its intended purpose of mixing audio signals from microphones. Misuse may result in damage to the unit or connected equipment.
- Cable Connections: Always ensure that all cables are securely connected before operation. Use appropriate 3.5mm (TRS) cables for inputs and outputs.
- Environmental Conditions: Avoid exposing the mixer to extreme temperatures, humidity, dust, or direct sunlight. Keep it away from liquids.
- Cleaning: Clean the unit with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Passive Device: The CAM-3 is a passive mixer and does not require external power or batteries. It does not amplify signals but rather attenuates them.
- Legal Disclaimer: Warranty does not cover misuse of the product.
3. Product Overview
The AZDEN CAM-3 Mini Audio Mixer features three input channels, each with an independent volume slider, and a single stereo output. Its compact design allows for easy attachment to a camcorder or hand-strap.
This image displays the top and front view of the AZDEN CAM-3 Mini Audio Mixer. It features three 3.5mm input jacks labeled CH1, CH2, and CH3 on the front edge. On the top surface, there are three corresponding slider controls for adjusting the volume of each channel, marked from MIN to MAX. An 'OUT' 3.5mm jack is located on the front right side. The device is black with white labeling for channels and the 'AZDEN AUDIO MIXER CAM-3' brand and model.
Components:
- CH1 Input Jack: 3.5mm mono input for Microphone 1.
- CH2 Input Jack: 3.5mm mono input for Microphone 2.
- CH3 Input Jack: 3.5mm stereo input for Microphone 3.
- CH1 Volume Slider: Adjusts the input level for Channel 1.
- CH2 Volume Slider: Adjusts the input level for Channel 2.
- CH3 Volume Slider: Adjusts the input level for Channel 3.
- OUT Jack: 3.5mm stereo output to connect to your camcorder.
4. Setup
Follow these steps to set up your AZDEN CAM-3 Mini Audio Mixer:
- Attach the Mixer: Securely attach the CAM-3 mixer to your camcorder using its integrated mounting mechanism or to a hand-strap. Ensure it is stable and does not obstruct camcorder controls.
- Connect Microphones:
- Plug your first microphone into the CH1 Input Jack.
- Plug your second microphone into the CH2 Input Jack.
- Plug your third microphone (or a stereo microphone) into the CH3 Input Jack.
Note: Channels 1 and 2 are mono inputs, while Channel 3 is a stereo input. Ensure your microphones are compatible with 3.5mm (TRS) connectors. If using active (powered) microphones, ensure they have their own power source.
- Connect to Camcorder: Connect the supplied 3.5mm stereo cable from the OUT Jack on the CAM-3 mixer to the microphone input jack on your camcorder.
- Initial Volume Settings: Before recording, set all three volume sliders on the CAM-3 mixer to their minimum (MIN) position.
5. Operation
The AZDEN CAM-3 is a passive mixer, meaning it does not amplify audio signals. Instead, it allows you to attenuate (reduce) the volume of individual microphone inputs to achieve a balanced mix before the signal reaches your camcorder.
- Power On Camcorder: Turn on your camcorder and set its audio input to the external microphone setting.
- Adjust Camcorder Input Level: If your camcorder has an adjustable input level, set it to an appropriate level, typically around the mid-point, or as recommended by your camcorder's manual for external microphones.
- Set Mixer Levels:
- Start with all CAM-3 sliders at MIN.
- Gradually increase the slider for the microphone that has the strongest signal or the one you want to prioritize, moving it towards MAX until a suitable level is achieved.
- Then, adjust the sliders for the other microphones (CH1, CH2, CH3) to balance their levels relative to the first, ensuring no clipping or distortion occurs.
Tip: The goal is to prevent any single microphone from overpowering the others or causing the overall audio signal to peak and distort. Since the mixer is passive, it is best used with microphones that provide a strong output signal.
- Monitor Audio: Always monitor the audio output through your camcorder's headphones or audio meter to ensure optimal sound quality and proper mixing.
- Recording: Once levels are balanced, begin your recording. Adjust sliders as needed during recording if sound sources change in volume.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your AZDEN CAM-3 Mini Audio Mixer.
- Cleaning: Regularly wipe the exterior of the mixer with a soft, dry, lint-free cloth to remove dust and fingerprints. Avoid abrasive materials or chemical cleaners.
- Storage: When not in use, store the mixer in a cool, dry place, away from direct sunlight and extreme temperatures. Protect it from physical impact.
- Cable Care: Inspect all connecting cables periodically for signs of wear or damage. Replace damaged cables immediately to prevent audio issues. Avoid sharp bends or kinks in cables.
- Connector Care: Keep the input and output jacks free from dust and debris. Use compressed air if necessary, but avoid inserting objects into the jacks.
7. Troubleshooting
If you encounter issues with your AZDEN CAM-3 Mini Audio Mixer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Incorrect cable connections; Camcorder input not set to external mic; All mixer sliders at MIN. | Verify all 3.5mm cables are securely connected. Ensure camcorder is set to external microphone input. Increase mixer channel sliders. |
| Weak or low sound level | Mixer sliders too low; Camcorder input level too low; Microphones have low output or are unpowered (if active mics). | Increase individual channel sliders on the mixer. Adjust camcorder's audio input level. Ensure active microphones are properly powered. Remember the CAM-3 is passive and does not amplify. |
| Humming or static noise | Poor quality or damaged cables; Electrical interference; Ground loop. | Use high-quality, shielded 3.5mm cables. Ensure cables are not near power sources or other electronics causing interference. Test with different cables. |
| One channel not working or weak | Loose connection for that channel; Faulty microphone or cable; Slider at MIN. | Check the microphone and cable for the specific channel. Ensure the corresponding slider is not at MIN. Test the microphone directly with the camcorder if possible. |
If the problem persists after attempting these solutions, contact AZDEN customer support for further assistance.
