Hello,
I have for sale some nice and shiny stuff.
This time I have a few pairs of modules that can be used as a low thd line preamp or as an low thd amplifier front end, you know to drive a follower os.
These have balanced inputs, single ended outputs and a voltage gain of ~10x which can easily be changed on each side by replacing 2 smd resistors.
You can power them with up to +/-29vdc and they draw 30ma/entire module.
Each of the two big pcbs hosts 2 preamp channels.
These channels are connected in such a way that you can use them only for biamping so half pcb amplifies the lows and half the highs or whatever being same channel, for a stereo setup 2 pcbs will be needed.
Here is how the thd looks at 2.85vrms or close to 1w/8r
And here at close to 17vrms or close to 36w/8r
Now probably you wonder what are those small pcbs, right?
Well the preamp produces a turn on thump and the small module is a relay that keeps the output shorted to gnd for a few seconds so it silences the thump.
The offer includes 2 preamp modules(4 channels) and 2 thump silencer modules.

Thanks for the question, good one.
Yes it will drive an F4 up to 35w/8r or 70w/4r.
