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 1Amp external power supply that is included in the delivery.
And what's more... no hassle with how do I connect this thing to my WEBSTATION / 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.
