Wiring Example

Please leave the terminals K2-K10 alone, which were designed for other purposes. If you want to turn on an external LED light when the device is playing a sound, you can use the last two teriminals Load- & Load+, which outputs the same voltage as the voltage you supply to the device, so suppose you supply a 12V power source to the device, you need to make sure the LED light can also work on 12V as well.
