Claic mechanical volume knob

Turn the knob to switch the machine on and off, no need to pre and wait to see the indicator light.

Timele place of claic mechanical volume knob:

1. With volume scale, you can know the current volume. The digital tuning position is unknown. I don't know the current volume. I will be startled by the sudden loud volume when I turn on.

2. Turn it off when the volume is turned to the lowest, which is not easy to damage the speaker and power amplifier.

3. The mechanical switch turns off without long preing and waiting, which is convenient and fast.

4. The real steple tuning is not digital multi-stage grading adjustment.
