මෙහෙයුම් උපදෙස්

පරිමාව පාලනය

The Aune Yuki features two buttons on its back for volume adjustment. The button with the dot is for Volume Up, and the other button is for Volume Down. These buttons control the device's internal volume.

Changing Gain Level

To switch between high gain and low gain modes, press and hold both Volume Up and Volume Down buttons simultaneously for 2 seconds. You will notice a change in volume, indicating the gain level has been adjusted. High gain is suitable for harder-to-drive headphones, while low gain is ideal for sensitive IEMs.

UAC1.0 Device Compatibility (e.g., Nintendo Switch)

For devices that support UAC1.0 (such as the Nintendo Switch), please hold down the Volume Up button on the Yuki and do not release it until the two devices are connected by cable and the Yuki is powered on. This ensures proper recognition and functionality.
