7. What does the front indicator light mean under different input states?

A:

1.USB DAC:
Sampling rate ≤ 48kHz: Blue light;
Sampling rate ＞48kHz: Yellow light;
DSD: Green light.

2. Line in:

The front light will flash in Blue. (It only means the Q5s TC is powering on, but not the sampling rate, because the Q5s TC is unable to know the sampling rate of the input device.)

3. Optical/Coaxial input:
Sampling rate ≤ 48kHz: Blue light;
Sampling rate ＞48kHz: Yellow light.

4. Indicator light under Bluetooth state:

Different colors indicate different Bluetooth states and formats. Details are shown in the following pictures：

In addition, when charging the Q5s, the four lights on the side of the fuselage will flicker successively in the form of horse lights, and the side lights will no longer indicate the current input state.
If the user needs to check the current input state, he/she can press the function selection button for a long time, and the side indicator will indicate the current input state for 3 seconds, and then return to the charging state after 3 seconds,
4 side lights are always on when fully charged.
