Rockruepel COMP.TWO - Modern tube compressor

Modern tube compressor

Vari-MU = Vari-Glue

The COMP.TWO plugin is a faithful emulation of the German-built hardware compressor by Rockruepel (Rock-bully in English). It is an all-tube vari-mu design, meaning there are no transistor stages in the circuit. Ideal for adding glue to your mix.

Input

Input gain applied before compression on channel 1.

Output

Output gain applied after compression and before Mix (dry/wet) on channel 1.

Mix

Mix between dry and wet parts of the signal on channel 1.

Threshold

Threshold value setting at which volume signal starts to be reduced on channel 1.

Attack

Controls if the compression happens fast or slowly when the signal hits above the threshold on channel 1.

Release

Controls if the compression stops fast or slowly when the signal hits under the threshold on channel 1.

Sidechain HP

Add a High Pass filter on Sidechain input signal on channel 1.

Amp Only

Activates the compression or uses the plugin in an amp only mode.

Transformers

Simulates analogic transformers from Rockruepel original hardware or lets you have a clean signal.

Stereo Mode

Selects which part of the signal will be processed per channel: Stereo is a link mode between left and right. Dual Mono processes Left (ch. 1) and Right (ch. 2). Mid/Side processes Mid (ch. 1), and Side (ch. 2).

Visualizer

An optional visualizer allows to display input and output signals interacting with the compressing reduction on a time scale.

Console

Displays the Console, to take control of any COMP.TWO instance.

The Rockruepel History

The Rockruepel History

Oliver Gregor, soldering iron in hand, has been building all sorts of machines since kindergarten. It is during his tenure as a tech at Skyline Studios in Düsseldorf that his love for music and electrical engineering merged into a relentless quest for creating the best audio equipment.

Amp only & transformers

Amp only & transformers

The appeal of a compressor is as much the inherent sound of the unit as its ability to compress material. Using the same type of output tubes as the old Altec and RS124 compressors and with beautifully sounding Sowter transformers in the output stage, the COMP.TWO is also a great vibe box, with or without compression.

One+Time=Two

One+Time=Two

A compressor is only as useful as its side chain is smart and flexible. Through years of refinement Oliver made sure that COMP.TWO has none of the limitations of traditional monolithic vari-mu circuits and can be as clean or as dirty as you need, as fast as an 1176 or as slow as a Fairchild, all with the texture and tone of a classic tube compressor.

Modern controls

The team at PROCESS.AUDIO captured and recreated every nuance of the hardware and added its signature set of controls, like the Console Remote which lets you control all instances of the COMP.TWO plugin from a central interface, MS capabilities, high-pass filter on a sidechain, DRY/WET control, and of course, lots of presets designed by world-class producers and mixers.

Visualisation

Compression can be tricky to perceive, so PROCESS.AUDIO created a visually pleasing and easily readable gain reduction visualizer to aid in precise gain matching and provide a true understanding of the impact of the settings on the program material. That's in addition to faithfully recreating the two gorgeous VU meters of the hardware units.

Bass 1

Bass is a difficult instrument to place in the mix. Often is does not read well and you’re stuck with it being too loud or too soft. Sugar’s LOW and MID sections were designed in part to help with that. The DRIVE circuit is also very useful to bring out harmonics and help the bass cut through. In this example you can immediately hear how the LOW section creates a pillow at the bottom and how the saturation brings the harmonics up. It also adds a cool buzz to the track which will help the bass cut through the mix without having to be pushed up.

Testimonials

Fast and easy to dial in, and a perfect match to my hardware unit.

Fab Dupont — Award-winning engineer

I couldn’t believe it! I never thought a PlugIn could have the sound, the feel and look of my favorite Mastering Compressor. Now I can use it more than once!

Stefan Heger — Mixing engineer

The Comp.Two plugin has a very true sound, just like the hardware version. I always use the compressor on vocal mixing and this allows for running the plug in on several stems and tracks.
