Eden Mic Preamp

Eden Mic Preamp


This is the Eden Microphone Preamplifier from Expat Audio.
It comes as a completed module that only needs to be hooked up.
In fact, all it needs is power, input, output and a gain setting resistor.

It’s assembled and tested here in Texas, USA.

Similar Systems
IC Mic Pre’s like this have been used in many systems, such the Toft ATB Console, Trident S-20 mic pre, the DAV BG1 mic pre, Symetrix 302, dbx760X, D+R and Amek consoles. (that list from searching online)

It has flat THD+N at 30dB of gain as low as 0.003%, all the way to 30kHz (higher I believe – but the audio test kit isn’t quite up to it).
At 60dB of gain (max setting) the THD+N is still very impressive at 0.04%. (again, flat all the way!)
