Tegeler Audio VTRC Vari Tube Recording Channel

The Tegeler Audio Vari Tube Recording Channel gives your recordings a high-end boutique sound while at the same time perfect integrated into your mix. Due to the variable nature of the preamp, you can decide on color of the sound of your recording varying from clean direct to vintage fat. With the passive equalizer built after the Pultec principle, you can add silky soft highs to your recording, give your voice more volume or filter out disruptive frequencies within the area of keynotes. The combined operation of vari-mu and optical compression of the VTC is a unique worldwide feature that extends your sound spectrum with a fantastically sounding compressor tone.

Optical Compressor

An LED beams onto a light-sensitive resistor and regulates the gain depending on the level. The automatic control of the compressor timing is additionally supported through the memory effect of the resistor. The result is an open-airy and softer compression which keeps the level nicely static but hardly alters the microdynamics of the signal.

Vari-Tube Compressor

With this setting the amplification of a control tube is influenced directly. The control happens directly through the optical compressor. The result is a sound that will find its place even in a dense mix with a sinister presence while never losing its warmth.

The routing of the compressor and EQ is switchable, it is possible to switch the EQ into the sidechain of the compressor so that frequency dependent compression and de-essing are both possible. If you have a recording that has not yet been refined with the aid of the VTRC, it is possible to edit it also afterwards through the new line input. Thereby the signal does not pass through the Microphone input transformer, but through a separate transformer that has been developed for line level.

All functions of the VTRC (from Preamp to EQ to Compressor) are available to you for the processing of high level signals.

If you want to use the VTRC for stereo signals, it is possible to link them.
