Introduction
The UGREEN 3.5mm to 1/4 Audio Cable is designed for connecting devices with a 3.5mm (1/8 inch) jack to audio equipment featuring a 6.35mm (1/4 inch) jack. This cable facilitates high-fidelity audio transmission between various devices such as smartphones, laptops, guitars, amplifiers, and mixing consoles.
Key features include:
- Astonishing Sound Quality: Equipped with 24K gold-plated, corrosion-resistant connectors and double shielding for optimal signal transmission, delivering clear, crisp, noise-free, and high-fidelity audio. Note: For stereo audio output, the playback device must support stereo processing.
- Upgraded Durability: Features a zinc alloy case and double-layer nylon braid to protect against wear and tear, ensuring longevity.
- Lossless Audio Transfer: A pure copper core maximizes conductivity and durability, enabling high-purity audio signal transfer with minimal loss.
- Wide Compatibility: Connects devices with a 3.5mm jack (e.g., phones, iPods, laptops) to equipment with a 6.35mm jack (e.g., guitars, mixing consoles, home theater systems, amplifiers).

Setup Instructions
Follow these steps to correctly set up your UGREEN 3.5mm to 1/4 Audio Cable:
- Identify Connectors: The cable has two different sized male connectors: a 3.5mm (1/8 inch) TRS connector and a 6.35mm (1/4 inch) TRS connector. Ensure you identify the correct port on your devices.
- Connect 3.5mm End: Insert the smaller 3.5mm connector into the audio output jack of your source device (e.g., smartphone, tablet, laptop, MP3 player). This is typically labeled as "Headphone Out" or "AUX Out".
- Connect 6.35mm End: Insert the larger 6.35mm connector into the audio input jack of your receiving device (e.g., guitar amplifier, mixing console, digital piano, speaker). This is often labeled as "Input", "Line In", or "Instrument In".
- Secure Connection: Ensure both connectors are fully inserted into their respective ports to establish a stable and secure connection.

Operating Instructions
Once the cable is connected, operate your devices as follows:
- Power On Devices: Ensure both the source device and the receiving audio equipment are powered on.
- Select Input: On your receiving audio equipment (e.g., amplifier, mixer), select the correct input channel corresponding to where the 6.35mm cable is connected.
- Adjust Volume: Start with a low volume level on both devices and gradually increase it to a comfortable listening level.
- Stereo Output: This cable is designed for stereo audio. For optimal stereo sound, ensure your playback device supports stereo processing. If connecting to a mixer, use a stereo input/output port instead of a mono port.
- Guitar Connection: When connecting an electric guitar, note that electric guitars typically output a mono signal. To achieve a stereo setup, an additional amplifier or stereo processing unit may be required.

Maintenance
To ensure the longevity and optimal performance of your UGREEN 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 at sharp angles to prevent internal damage.
- Cleaning: Use a soft, dry cloth to wipe the cable and connectors. Avoid using harsh chemicals or abrasive materials, which can damage the gold plating or cable jacket.
- Handling: Always grasp the connector housing when plugging or unplugging the cable, rather than pulling on the cable itself. This prevents strain on the connection points.
- Inspection: Periodically inspect the cable for any signs of wear, such as fraying, cuts, or bent connectors. Replace the cable if significant damage is observed to prevent potential audio issues or further damage to connected equipment.
