@Nomad Do you mean you are soldering on some speaker wires from an external speaker directly to the EZ-Bv4 spkr port?

In this case the voltage doesn't really matter. The audio signal is a low voltage (3.3V or below) and all wires that I know of can handle that voltage.

Hi @Nomad, I just tried it. It works, but it doesn't work very well. The audio signal is an AC signal and an LED normally works with DC signals. The brightness of the LED isn't bright enough to get a good effect. I would recommend using a digital port with the Talk servo control. If you are using a sound board then you can use the sound servo control. Both are located in the Audio section of Controls.
