Video and Audio Source
Depending of which of the 4 connection options are employed, video
and audio sources with the following characteristics should be
employed.
Connector Signal
Video Input 75 ohm composite video source, PAL or NTSC
software selectable
Audio Input Line / Microphone level audio, switchable.
Line level -2dBu clip level low impedance
source (< 600 ohm)
Microphone level 12, 24, 36 and 48dB preamp
stages software switchable
Microphone power is provided on the audio connectors at approximately 3V (suitable for Electret
microphones)
Typically the video source will be a small colour or black and white CCD
camera.
Typically the audio source will be an Electret microphone.
DC Power Source
The transmitter unit can be powered from a nominal 12V DC supply or
an AC to DC adapted supply.
The connected 12V DC input should have the following characteristics.
• Input Voltage Range – 5.9V to 16V, reverse voltage protected.
• Current draw - 0.35 to 0.28A at 12V (mode dependant)
domo can supply optional AC to DC converter blocks to power the
transmitter unit, the domo part number is PSU12
