Vintage Tube Distortion






Owner's manual:


Overview

Redoptor is a high quality Vintage Tube Distortion emulator.

The popularity of tube distortion units are as a result of their superiority over the solid-state fuzz distortions which are based on transistor clipper circuits.

Tubes produce even and odd harmonics and naturally compress the signal. Transistors produce only odd harmonics and limit the sound.

In ordinary fuzz, when a signal goes over the threshold level it goes through the clipper circuit. As the signal volume falls back below the threshold (as the sound reaches its release stage), the harmonics added by clipping suddenly disappear. If the volume of a signal oscillates above and below the threshold, the clipping harmonics will appear and disappear with the signal level. This sounds unnatural and is unpleasant to listen to.

This does not happen in Redoptor. As the sound source falls in volume in its release phase, the harmonics (which were created by the sound being initially above the clipper threshold), gently disappear with the original sound. This creates a very sonically pleasing distortion.

Exact circuit emulation

Redoptor has an adjustable tube bias parameter. This allows subtle amplification of even harmonics and gentle transient reshaping in the signal. Similarly, like a hardware tube distortion, Redoptor reacts dynamically to each change in the amplitude of the input signal. As a result, the amplitude of even harmonics is not constant in time.

Redoptor has a very precisely modeled tube distortion module. The emulation doesn’t just focus on the characteristics of the tube part of the circuit; it also models the rest of the circuits co-functioning with the tube within the distortion unit to capture all the subtleties’ and dynamics of proper high-quality analog tube distortion.

Completely adjustable preamp

In a typical guitar amplifier, the preamp is usually fixed. In Redoptor it is not. Redoptor allows the cut-off point for low and high tones to be set before the signal is amplified.

Parametric EQ

Redoptor has a full parametric equaliser with 4 controllable bands. This degree of EQ is rare in this type of device. Most typical amplifiers have a fixed graphical equaliser, with 3 or 4 bands and only allow gain of the signal in each band.

Independent stereo channel processing

Redoptor is not just for guitarists - who usually only require a mono signal path for distortion. Redoptor is a fully functioning stereo tube distortion with an independent path for each channel in the stereo signal. This allows each channel to have completely different harmonics and distortion added to it. Try doing this with synth sounds – the timbre will sound much more defined.

Unique character

Thanks to the perfect emulation of the electronic circuits within the various guitar amplifiers used to design and create Redoptor, Redoptor sounds as good as its real-world analog equivalent.

Guitarists will appreciate the quality of Redoptor. For them, the amplifier is indispensible.

However, other instrumentalist and sound designers will also welcome the high quality distortion, rich harmonics and attitude which Redoptor brings to their sounds.

Use Redoptor on guitar, drum loops, arpeggiated sequences, synthetic or acoustic sounds and you’ll hear its warm, rich and truly unique character.

Pro|tone, 01/2011
» All our testing can be summed up quickly: the SilverLine series is outstanding and unique in sound quality. – you might have realized this by our kind of passionate writing as well. [...] your production will get a lot more precious character with these – in fact, that’s all SilverLine is about: giving a special touch to the sound, not being just another standard plugin series. «
Wusik Magazine, August 2009
» As I come to expect from d16, Redoptor is a very high-quality tube distortion plug-in. It is capable of wearing different "sound masks." It can give digital instruments a vintage, older-quality sound. It can be pleasant, warm and clean one minute, yet it can distort your audio material like there's no tomorrow. One thing I learned in processing loops is that it is sometimes good to apply a bit of saturation or subtle distortion to make them "jump-right-out-of-the-speakers". Redoptor fits perfectly for this job because it imparts a good tube sound - giving new life to older drum and percussion loops. The results can be satistfying with this trick. And trust me, Redoptor is up to the task. (read whole review) «
Beat, September 2009
» Der charakteristische, obertonreiche Klang analoger Röhrenverzerrer wird von Redoptor überzeugend nachgebildet, wobei das Plug-in wie seine Hardware-Vorbilder dynamisch auf Amplitudenänderungen des Eingangssignals reagiert. Redoptor ist eine hervorragend klingende Geheimwafe, um verschiedenste Signale mit Obertönen anzureichern oder subtil bis brachial zu verzerren. «
Sound On Sound, June 2009
» Silver Line effects and processors stand out from the crowd of vintage emulations. D16 appear to be less interested in your classic Neves and Pultecs, and more in the design quirks and technological limitations that gave older electronic instruments their individual qualities [...] These plug-ins offer something that is authentically 'vintage' yet also rather different from the bulk of what's out there. «
Computer Music, (138) March 2009
» In short, Redoptor sounds excellent on all manner of signals, and seems to offer a smoother transition from clean to distorted than many plug-ins of this type. [...] As far as guitars go, if you're not quite satisfied with the valve tones of your current software, you could buy Redoptor to use in conjunction with it, as a preamp. «
Waveformless, 4/2009
» D16 have clearly done their homework and have made sure that there is something unique about their approach to separate them from other takes on the same sorts of plug-ins. The differences are usually subtle ones, but they’re ones that go a long way towards making the effects sound as good as they do. [...] If you’re looking for a variety of ways to distort your audio with a very organic, hardware-type sound, this suite should be in your collection. Period. (read whole review) «
