The Discrete Line Driver is the Class A, No-Feedback Loop Transformer Driver Colour Module. The design was inspired by the circuitry from Vintage Console from 60’s.
The Discrete Line Driver is made with Vintage NOS Silicon and Germanium transistors. The main driver circuit is build with three transistors creating a compact circuit with no Feedback Loop!
This special circuit is completely stable in the AC and DC domain. The Driver Circuit is DC coupled with the output transformer.
As a result, the Discrete Line Driver produces plenty of harmonics and provides better saturation of the output transformer.
The FEEDBACK jumper reduces the amount of harmonics and makes the sound cleaner.
The fourth Germanium Transistor in the input stage has the LF resonant circuit. If the LBOOST jumper is shorted, the module produces a low-frequency bump, saturating the output transformer in the LF’s.
The Discrete Line Driver Colour Module produces thick and full sound, just like the line drivers in the Vintage Mixing Consoles.
