MOS UNO - Microphone OnAir Switch

Suitable for signaling of on-air lamps for microphones. e.g. YELLOWTEC MIKA ON-AIR MIC ARM.

ON-AIR = red
OFF-AIR: white

POWER LED INDICATOR
The LED will light up when the 12VDC power supply is present.

12VDC POWER INPUT
Ratings: 12VDC (9~18 volt) at 250mA. The polarity is not important
Power supply is included

MIC OUT (TO STUDIO)
Microphone output; connect to your equipment with standard MIC cable
(XLR 3pin)
- PIN1: Ground (Shield)
- PIN2: Positive (Red)
- PIN3: Negative (Blue)

MIC ONAIR ARM
Connect to the MIC ON-AIR ARM with standard MIC cable (XLR 5pin)
- PIN1: Ground (Shield)
- PIN2: Positive (Red)
- PIN3: Negative (Blue)
- PIN4: LED (Yellow)
- PIN5: LED (Black)

The supply voltage may be between 9 and 18 volts DC; the polarity is not important.

​On pin 1 and 6 of the 9 pin sub D female or on pin 1 and 2 of the RJ45 a voltage can be applied. Again, a DC voltage; the polarity is not important and the voltage may be between 5 and 18 volts

​On pin 2 and 7 of the 9 pin sub D female or on pin 3 and 4 of the RJ45 a switching contact.

​On pin 3 and 8 of the 9 pin sub D female or on pin 5 and 6 of the RJ45 a toggle function to let the white light signal burn continuously or fluctuate. When activated, the LED on the box will flash briefly. Flashing twice means the white light is on continuously, flashing three times means the white light will fade in and out after approximately one minute.

RJ11 may only be used to connect to the MOS quatro in sync with the white light signalling of the quatro.
