1. Introduction
The ELECOM AV-351 Audio Cable is designed to facilitate audio connections between portable devices. This 1.0-meter cable features stereo mini plugs on both ends, making it suitable for connecting portable CD players, MD players, and similar audio equipment for recording or playback purposes. It is engineered for high-quality signal transmission with minimal distortion.
2. Setup and Connection
Follow these steps to connect your ELECOM AV-351 Audio Cable:
- Identify Connectors: The AV-351 cable has identical stereo mini plugs (3.5mm) on both ends.
- Connect to Source Device: Insert one end of the audio cable firmly into the audio output jack of your source device (e.g., portable CD player, smartphone headphone jack).
- Connect to Receiving Device: Insert the other end of the audio cable firmly into the audio input jack of your receiving device (e.g., MD player's recording input, amplifier's AUX input).
- Secure Connection: Ensure both plugs are fully inserted into their respective ports to prevent loose connections and signal loss.

3. Operating Instructions
Once the cable is connected, operate your devices as follows:
- Power On Devices: Ensure both the source and receiving audio devices are powered on.
- Select Input/Output: On your receiving device, select the correct audio input source (e.g., AUX, Line-In) that corresponds to where the cable is connected. On your source device, ensure audio output is enabled.
- Adjust Volume: Start with a low volume setting on both devices and gradually increase to a comfortable listening level.
- High-Quality Transmission: The cable's 24K gold-plated pins and high-purity 99.996% Oxygen-Free Copper (OFC) construction are designed to minimize signal degradation and distortion, providing clear audio.
4. Maintenance and Care
To ensure the longevity and optimal performance of your audio cable, follow these maintenance guidelines:
- Storage: Store the cable in a clean, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling or bending the cable sharply, as this can damage the internal wires.
- Cleaning: Use a soft, dry cloth to wipe the cable and connectors. Do not use harsh chemicals or abrasive cleaners.
- Handling: Always grasp the connector housing when plugging or unplugging the cable, rather than pulling on the cable itself.
- Tangle-Free Design: The cable features a tangle-free design, which helps prevent knots and extends its lifespan.
5. Troubleshooting
If you encounter issues with your audio cable, consider the following:
- No Audio Output:
- Ensure both audio devices are powered on.
- Verify that the cable is securely connected to both the output jack of the source device and the input jack of the receiving device.
- Check the input selection on your receiving device to ensure it is set to the correct port.
- Confirm that the volume levels on both devices are not set to minimum or muted.
- Test the cable with different devices if possible to rule out a device-specific issue.
- Poor Audio Quality (Static, Distortion, Low Volume):
- Ensure the connectors are clean and free of dust or debris.
- Verify that the plugs are fully inserted into their respective jacks.
- Check for any kinks or damage along the cable length.
- Ensure the audio source is playing high-quality audio.
