Feature

If you have a Class A amplifier or a high-power Class A amplifier, or BTL amplifier, you need to use a high-current speaker protection board, the shop recommend a 30A 2.0-channel speaker protection board, BTL power amplifier need to two pieces. PCB double-sided tin plating 1.6 Mm, speaker protection chip UPC1237, 7812 regulator, audio connection with 7.02 terminal, high-power horn protection board, the use of fully sealed high current pine music relay, can control the DC voltage 1500V, over current 30AX2.

Horn protection board has a power-on delay (about 3 seconds) and DC protection (starting voltage of about 1V)
Function, board circuit is simple, wiring is easy, work is safe and reliable. With LED work light indication, when the protection is extinguished, light up when working normally. Use 30A high current relay, suitable for high power amplifier.
