The Studio Signal Light is easy to control. Illuminate them with 12VDC. If you have a broadcast console with built-in logic, you can drive these directly. Or make your own interface. Better yet, use the Angry Audio Studio Signal Light Gadget designed just for this purpose. Your studio is going to be beautiful. The Studio Signal Light is a really bright idea. Imagine one of these in every control room and every studio to give visual cues to talent and operators as needed. Everyone knows the red light means the mics are hot. But once the mics are hot, you might need to signal something. Maybe a light comes on to indicate a break is imminent. Or another light represents a ringing phone line. You’ll have fun figuring out how to use them. And once in place, you’ll wonder how you ever worked without them.
