I want to introduce a new preamp project.
After collecting some parts oveer several months, now the main parts are together and ready for wirering.
All parts are from professional studio equipment with best audio quality. Each single module has balanced transformer coupled I/Os (high quality transformers don't reduce the audio quality) and is internal active with +22dB headroom.
The faders are equiped with P+G 5" conductive plastic resistors.
The equalizers (mono) are parametric with different bandwidht and center frequency.
