Audio Preamplifier Board, Preamp Module 3 Channel Adjustable Durable  for Replacement

<ul><li>NE5532P Chip: Other op amp chip such as OPA2604AP OP275G TL072, etc. can also be replaced, very simple and practical</li><li>Board Structure: 3 channel output, treble, bass, midrange, which ensures  sound quality and more audio enjoyment</li><li>Crossover Point: 500HZ, 5kHZ, that is, 20HZ-500HZ is bass output, 500HZ-5KHZ is midrange output, 5KHZ-20KHZ is treble output</li><li>Filter Type: Subtractive divider, also comes with -24dB/Oct attenuation slope, so the preamp module has high efficiency</li></ul>
