The switch on the far left is 'Hi-Fi.'
Switch in the centre is 'Boost 1'.
The switch on the far right is 'Boost 2.'
3. If the signal line is not shielded or the power supply is not well filtered, noise may be generated. It is recommended to use shielded wires and a clean power supply for testing.
4. The tube buffer is amplified by about 5 times. The pre-amp has an amplification function, which is connected between the audio source, the pre-amp and the power amplifier. The noise from the audio source is amplified, so please use a good audio source to test.
