3. Operating Instructions

The LICAEVEY Volume Control Box provides intuitive control over your audio levels.

Volume Adjustment: Use the two potentiometers (knobs) on the top of the device to adjust the volume. One knob controls the left channel (L), and the other controls the right channel (R).
Channel Balance: By adjusting the left and right knobs independently, you can achieve precise stereo sound balance according to your preference.

Important Notice:

• Do not adjust the speaker directly using this device.
• Do not adjust the headset volume directly using this device.

This device is intended for controlling the line-level audio signal between an audio source and an amplifier, preamplifier, or powered speakers, not for direct control of passive speakers or headphones.

5. Troubleshooting

If you encounter any issues with your volume controller, please refer to the following common troubleshooting steps:

Problem	Possible Cause	Solution
No sound output.	Cables not fully connected. Volume knobs turned down completely. Incorrect input/output connection. Audio source or output device issue.	Ensure all 3.5mm cables are securely plugged into the correct IN/OUT ports. Rotate both L and R volume knobs clockwise to increase volume. Verify that the audio source is connected to IN and the output device to OUT. Test your audio source and output device independently to ensure they are functioning correctly.
Distorted or unclear sound.	Poor cable quality or damaged cables. Volume set too high on source or output device.	Try using different 3.5mm audio cables. Adjust the volume on your audio source or output device to a moderate level before fine-tuning with the controller.
Sound only from one channel (left or right).	One of the L/R volume knobs is turned down. Faulty audio cable or connection. Issue with the audio source or output device.	Ensure both L and R volume knobs are adjusted to desired levels. Check and replace audio cables if necessary. Verify the stereo output from your audio source and input to your output device.

If the problem persists after trying these steps, please contact customer support.
