ENG MIXER .

I will make video recordings of my German WW2 radios.
I therefore need a ENG mixer.
It is specifically designed to connect to my radios.
It has two inputs, one for the microphone and one for line.
Line input is connected to my German radios.
Microphone input is 48 volt phantom power.



Here I test my mixer for the first time.
Taking a video that deals with an automatic Morse code transmitter.
Recording audio from a Fug10 receiver.
The sound be recorded on a laptop.
To synchronize sound with the picture I use a clapperboard.





The mixer has two inputs.
Input 1: XLR mic input with 48V phantom power.
Input 2: Transformer balanced line input with banana plugs.
The mixer has two outputs with RCA connectors.
These are also taken out to a headphone jack.
The mixer has four volume control.
Each of the two inputs can be mixed to each of the two outputs.





The switch at the bottom is the on / off switch.
The switch at the XLR connector is phantom power on / off.

My first film where I use the mixer.





I could also use the mixer as the microphone amplifier to my LO40K AM transmitter.





This is one of my AM stations. LO6K39a receiver and transmitter LO40K.
This LO40K is rebuilt to AM in Denmark after the war.
