Feature:
1. Single Power Supply: Input coupling capacitor uses imported brand infinite capacitors. The board is powered by a single power supply and has a voltage regulator chip, which is convenient to match with a single power amplifier
2. SMD Technology: Manufactured by SMD technology, the power input adds a rectifier bridge, which can be used for both AC and DC
3. No Need to Separate Poles: There is no need to separate the positive and negative poles when inputting DC, which is more convenient to use
4. Volume Potentiometer: Preamplifier board come with volume potentiometer, which possess more stable performance
5. Good Quality PCB Materials: Good quality PCB materials possess reliability and miniaturization, good maintenance and interchangeability
