You have experience with digital music production and with handling plug-ins but are aspiring to reach the professional league?

The digital sound editing of voices and solo instruments makes sense if you want to work mobile in the pre-production stage or want to quickly test certain equalizer or compressor types using their digital clones.

During the completion of your mix with the plug-ins, you realise that recorded voices don’t become prevalent, don’t integrate into your mix and clearly sound adapted.

Maybe you made the right decision in quality and bought a good microphone, however a premium mixing console is, to continue with quality, outside of your budget.

So far, you have vainly looked for a solution to that problem. A combination of a premium pre-amplifier, compressor and equalizer whic his made up of the finest components is available in only one piece of equipment and for an exceptionally fair price that is reachable for studios projects.

We at Tegeler Audio Manufactur as musicians had the very same problem and therefore shifted our focus towards the development of such a device. The VTRC. The Vari Tube Recording Channel gives your recording the most up market boutique sound and confident powers of self-assertion, while at the same time creating a perfect integration into the mix.

The device will astonish you with its sound results that are accredited to other high end devices within the top price range when used during blind tests.

It is the first sound refiner worldwide which allows for the combined operation of vari-q and optical compression and therewith offers a sound-spectrum ranging from clean precision to a silky warm vintage sound.

The VTRC absolutely convinced us and that is why we offer you to try out this device without any obligations for 14 days. Simply sign up at the above link and the VTC will be delivered to you on the same work-day (if available).

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-µ and optical compression of the VTC is a unique worldwide feature that extends your sound spectrum with a fantastically sounding compressor tone.

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.

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.
