  1>.This version already includes rectification and filtering circuits, so it is necessary to use a 3-wire transformer. Dual AC 12-32V can be used, and DC power cannot be supplied. If installed, it will burn
  2>.The chip generates a significant amount of heat, and in any case, a sufficiently large heat sink must be installed when powered on.
  3>.The chip must be insulated from the heat sink, otherwise it will burn out.
  4>.Using a standard ring transformer as the power source is a good choice, and adjustable power sources cannot be used.
  5>.All wiring should not be reversed or connected incorrectly, otherwise the chip will be burned.
  6>.There are positive and negative pins of electrolytic capacitor and diode, which cannot be reversed.
  7>.This product is single channel, to make dual channels, you need to purchase two sets.
