Description
- This board is powered by a single power supply, can share power with power amplifier board. There is a op-amp IC port for changing op-amp easily.
- Full frequency signal volume potentiometer is very convenient to alter to a preamplifier for 2.1 power amplifier.
- LED indicator light is great for real-time monitoring of power supply status.PCB uses super hard FR-4 glass fiber board.
- Signal transmission is concise, signal-to-noise ratio is very high.Support single/double sound channel input, support single channel output.
- Frequency adjustment range is 22Hz-300Hz, and there is no human voice in this range. Low-pass only has low frequency output, which needs power amplifier board to be used.Low frequency performance effort is related to amplifier board power and speakers matching.
