When the microphones are hot, you can’t just yell “Hey, you’re on!” That’s why you need the Studio Signal Light (broadcasters call these “tally lights”). The red segment tells everyone you’re on the air. Each colored ring is lit with multiple long-life, energy-efficient LEDs. Each segment is individually programmable to illuminate steadily, flash, or to appear to rotate. The molded enclosure is made out of strong ABS plastic and mounts easily on your tabletop; simply drill a hole in the table for the cable, and use the included screws to secure the Light. Segments are illuminated by 12VDC on a phoenix connector.
