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.<\/p>\n<p>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.<br \/>\nThe 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.<br \/>\nIt 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.<br \/>\nThe 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).<\/p>\n<h2 class=\"subheaderH2 divider-new\">Technology<\/h2>\n<p>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.<br \/>\nWith 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.<br \/>\nThe combined operation of vari-\u00b5 and optical compression of the VTC is a unique worldwide feature that extends your sound spectrum with a fantastically sounding compressor tone.<\/p>\n<div class=\"row\">\n<div class=\"col-sm-6\">\n<h3>Optical Compressor<\/h3>\n<p>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.<\/p>\n<h3>Vari-Tube Compressor<\/h3>\n<p>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.<\/p>\n<\/div>\n<div class=\"col-sm-6\">\n<h3><a href=\"https:\/\/www.tegeler-audio-manufaktur.de\/images\/vari_tube_recording_channel_4.jpg\" data-toggle=\"lightbox\"> <img decoding=\"async\" class=\"img-responsive z-depth-2\" title=\"vari_tube_recording_channel_4\" src=\"https:\/\/www.tegeler-audio-manufaktur.de\/images\/vari_tube_recording_channel_4.jpg\" alt=\"\" \/> <\/a><\/h3>\n<\/div>\n<\/div>\n<div class=\"twentytwenty-wrapper twentytwenty-horizontal\"><\/div>\n<p><i>The compressors bring the signal to the same level and compress it without compressing it to death.

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.<\/p>\n<p>All functions of the VTRC (from Preamp to EQ to Compressor) are available to you for the processing of high level signals.<\/p>\n<p>If you want to use the VTRC for stereo signals, it is possible to link them.<\/p>\n<div class=\"row\">\n<div class=\"col-sm-6\">\n<h3>New<\/h3>\n<ul>\n<li>Vari-\u00b5 compressor (Opto and Vari-\u00b5 comprossor can be used at the same time)<\/li>\n<li>Line input with separate line input transformer<\/li>\n<li>Two VTRC linkable for stereo operation<\/li>\n<li>EQ: 24kHz high boost frequency for additional air band<\/li>\n<li>Switchable compressor timing<\/li>\n<li>Upgraded tube input stage<\/li>\n<\/ul>\n<\/div>\n<div class=\"col-sm-6\">\n<h3>Proven<\/h3>\n<ul>\n<li>Opto compressor (Opto and Vari-\u00b5 comprossor can be used at the same time)<\/li>\n<li>Passive Pultec-style EQ<\/li>\n<li>Microphone preamp, character changeable from clean to fat<\/li>\n<li>EQ can be switch before or after compressor<\/li>\n<li>EQ can be switched to compressor\u2019s side chain<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p><a class=\"anchorlink\" name=\"h2-presets\"><\/a><\/p>\n<h2 class=\"subheaderH2 divider-new\">Presets<\/h2>\n<p>The VTRC is a device for professionals and does therefore not contain any pre-sets.<br \/>\nHowever, for the purpose of testing and to get to know the device, we have compiled some settings which for a good starting-point.<\/p>\n<div class=\"row\">\n<div class=\"col-sm-4\"><b>Basic settings<\/b><\/div>\n<div class=\"col-sm-8\">all controls set to 0, all switches to the bottom, Mic\/Line +48V according to the requirement.<\/div>\n<\/div>\n<div class=\"hr hr-narrow gap-small\"><\/div>\n<div class=\"row\">\n<div class=\"col-sm-4\"><b>Vocals<\/b><\/div>\n<div class=\"col-sm-8\">Gain set to 10, Input set so that the needle of the meter is just responding.
