M ONE Twin All FET Discrete Class A Microphone Preamp & DI

MOne-product-small1MOne-product-small2

We'd like to present our Twin All FET discrete Class A Microphone Preamp and DI. Design based on cascode topology with home-brewed transformers on Input and Output. Preamp has two cascades of amplification, first one is the main gain stage and the second one is the output booster. The Gain of Preamp controlled by the 12-step rotary switch reaches up to +70dB.

Output Volume control located between the first amplification stage and output booster. Two HPF 40 and 80 Hz passive LC filters provide great sonic behavior when engaged. The DI High-Z instrument input automatically activates if PL plug inserted, at the same time the XLR microphone input on back panel is disconnected. Both HPF can be used when the preamp is used as DI. All necessary Microphone Preamp functions such us -20dB pad, phase invention, +48V Phantom supply for condenser Microphone are controlled from the front panel.

The special about M One preamp is our transformer. We carefully collect all available knowledge form old masters, classic books and our own mistakes. As a result our transformers are superior sounding, which you will notice immediately. Our Microphone Input transformers utilize high grade 80% Ni-Fe alloy core with extremely low distortion.
