1. After powering on, the input defaults to Bluetooth mode.
If the blue light is flashing it is in pairing mode, and will
remain blue when connected.
2. When connecting via USB, press the input selection
key one time. The input mode will switch to USB AUDIO
mode. After switching successfully to USB AUDIO,
the light will remain green.
1. Gain selection is divided into three options: high, low and
super-low. High gain’s driving force is relatively large,
suitable for lower sensitivity and higher impedance
headphones. Low gain’s driving force is relatively small,
suitable for matching with headphones of higher
sensitivity and lower impedance. Super-low gain’s
driving force is smaller still, suitable for in-ear monitors
(IEM) with very high sensitivity and very low impedance.
2. Selection is made by sliding the switch.
