This ON-AIR warning light has no lamp inside any more, just everlasting high intensity red leds.
The unit is powered by a 12 volt DC 1A external power supply that is included in the delivery.

And what's more... no hassle with how do I connect this thing to my AIRLITE / AIRMATE / AIRENCE / AIRLAB / AXUM.
No complicated AC switching with external relays etc. etc.
What you only need is one stereo cable (wired tip/ring) coming from the MIC-ON (or GPO) connector on the back of the MIXER that goes directly hard-wired to a barrier strip inside the ON-AIR LAMP.
How easy is this for a change. The power adapter will also be directly wired to the barrier strip inside the unit.

There is a Cable entry hole and key slot holes on the backside for wall mounting.

We supply radial leads (as in the picture) instead of the original used axial leads.

Radial lamps are not avialable anymore from us, sorry.

But you can also ask us about the free LED conversion instructions for your VU meters.
