Tegeler Audio Manufaktur VTC Vari Tube Compressor

The Tegeler Audio VTC Vari Tube Compressor is built after the Vari-Mu principle, like it was used in the Fairchild 670 compressor, has a particularly distinct sound which sounds very musical and already adds the finishing touch to a lot of mixes.

Many hours of fitting, hearing and testing were spent on the VTC. The VTC starts the compression very gently and only intervenes more strongly at higher compression. A high-pass filter in the analysis circuit reduces the influence of low frequencies on the compression. Together with the appropriate attack and release settings, these measures ensure that the VTC is able to compress the sum without audible pumping, even with a compression of up to 6 dB.

The signal passes through a total of 3 transformers and 4 triode tubes per channel in the VTC.

Why is that important? Tubes (especially triodes) add overtones to the signal that the human ear perceives as pleasant and improves the perception of the individual sound sources. The individual instruments receive an additional presence through the tube. Transformers convert the current to a magnetic field and back as current and their non-linearities to provide a pleasant compression of the sound before it is compressed. The bass becomes tidier and more defined. The treble is pleasantly rounded off.
