Styled in blue and escrito en Español to better suit your linguistic predilections, this LED ON AIR sign from American Recorder is perfect for letting people outside your room know you're currently recording, and consequently, that they shouldn't bother you. It's not just for home-use, however: This sign is intended for flashing in recording studios, broadcast studios, schools, auditoriums, and theaters.

It features 20 bright LEDs, a high-impact ABS case, and a scratch-resistant acrylic panel. You'll find mounting hardware included, as well as a power supply and a 25' extension cable for installing the sign in a short amount of time.
