Save Your Speakers! upc1237 Protection Kit Build

Full step-by-step video on how to build a upc1237 speaker protection kit. Please SUBSCRIBE to my channel. Many amplifiers have a built in protection circuit that disconnects the speakers from the amplifier output if DC is detected due to a fault. DC on speakers will destroy them. Not amplifiers, however, have a protection circuit. In such cases, you really need a kit like this, especially if you have valuable speakers. The upc1237 is an IC that gives a startup delay (eliminating speaker thump), and also will disconnect the speakers if DC is detected on the amplifier output.
