WesAudio _RHEA 500 Series Vari-Mu Tube Compressor

Fully analog, stereo vari-mu tube compressor with digital recall, interstage CARNHILL transformers, and input and output level control for maximum flexibility


Product Description

Since digital footprint became part of the modern age, analog flavor was demanded more than ever. It is hard to imagine more musical and rich sounding compression than vari-mu desgin. This time ng500 line presents _RHEA - most noble of all, where modern age meets vintage, literally. The WesAudio _RHEA is true tube compressor, where gain reduction is literally implemented via tube circuit. As vari-mu design is feed backward compression, its behavior is known for amazing musical results! To properly integrate tubes into modern audio levels, just before signal is passed to the tubes, transformers are doing their magic, strongly emphasizing the low-end.

With MIX knob at your disposal, parallel compression has never been simpler to achieve, With _RHEA your MIX setting can be automated in your DAW. Did You ever wanted to push your compressor harder in chorus? Nothing simpler... just record automation using touch sensitive encoder, or draw your automation lines in DAW.


“Thump” or “Thumping” in vari-mu compressors is very specific effect when side chain control voltage gets into the signal. This is caused because of very small tubes imbalance. It may bring to the processed signal some additional low-end artifacts – in fact in many cases this may be a desired effect, as it will strongly emphasize low end content. However, for lower volumes and more gentle source materials, it can start to be audible. All our tubes get through very complex pairing and parameter checks, but some small differences can still cause this effect to happen. In this situation we would strongly encourage to raise the input signal and experiment with attack and release settings.


_RHEA allows to control the level on the signal going in the tube compression stage (Input), the amount of compression (Threshold), and finally the output of the compressor (Output). Such approach brings the best flexibility to alter the source material. It can be noticed that Threshold can be quite gentle in effect, however if more compression is desired, input knob can be used to this purpose. Please also note that each of those parameters can be automated, so don’t hesitate to change those settings in different sections of the song!


THD switch will enable a proprietary circuit which overloads output stage of the compressor. This circuit can be found in most of our units and it brings certain presence to the source material, which can’t be achieve using any other approach.


_RHEA is true stereo compressor which means that detector circuits of each channel are working on a summed signal in the side chain circuit. This makes it impossible to work in dual mono mode . However, it is entirely possible to work with only one mono channel at a time, so feel free to process a mono vocal track and have fun!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
