Vibrant Tube Compression in a 500 Series Module

The Wes Audio RHEA stereo compressor module is equipped with a tube gain reduction circuit to deliver highly musical results along with stellar audio quality, thanks to its fully analog signal path and bass-bolstering interstage transformers. And while the signal path is 100% analog, RHEA offers full control and automation from your DAW — the perfect combination of analog and digital technologies. A switchable harmonic distortion circuit allows you to add color and depth to your audio, and a mix knob makes it easy to apply parallel compression. Complete with highpass sidechain filters to prevent bass from over-triggering compression, the Wes Audio RHEA tube compressor module will exceed your expectations in terms of what a stereo bus compressor can do.

Full recall and automation when used with NG500-compatible racks

While the WesAudio RHEA compressor module will work with many standard 500 series racks, you'll be able to tap into advanced digital control when you load it into one of WesAudio's NG500-compatible racks, such as their TITAN series. NG500-compatible racks like the TITAN allow for digital control over your modules, facilitating full session recall and supporting automation from your DAW. In a typical 500 series rack, just connect a USB cable directly to RHEA for full recall capabilities.

Stellar sound quality with selectable harmonic distortion

No sonic compromises here: the all-analog RHEA stereo compressor module boasts a generous +24dBu of headroom. And if you want to add a little something special to your audio on the way through, switch on RHEA's THD (Total Harmonic Distortion) mode. With selectable Med and High modes, THD saturates your signal for added harmonic complexity — it's perfect for beefing up low end or adding complex midrange richness to your mixes.

Sidechain filters help prevent excessive compression

The RHEA compressor module offers three switchable highpass filters, which are extremely useful for preventing bass frequencies from triggering too much compression. Mix engineers at Sweetwater especially like this when using RHEA for stereo applications like drum overheads — the sidechain filter allows the sharp snare and cymbal sounds to trigger compression, while preventing the kick drum from overly triggering the compressor and crushing everything. With all these filter options, you'll be able to ensure loud bass hits don't cause your mix to implode.

WesAudio RHEA 500 Series Stereo Tube Compressor 500 Series Module Features:

  • All-analog signal path with +24dBu of headroom for stellar sound quality
  • Mix knob makes parallel compression techniques simple
  • Switchable THD (Total Harmonic Distortion) adds analog saturation to your signal
  • Switchable sidechain filters for fine-tuning how the compressor reacts to bass frequencies
  • Vari-mu-style compression; use Input and Threshold controls to dial in the right amount of compression
  • Compatible with any WesAudio NG500 chassis and many standard 500 series racks
  • Full session recall and support for DAW automation when loaded in an NG500-compatible chassis like TITAN, or via USB connection
  • Touch-sensitive encoders (Threshold, Mix, Output) allow you to draw automation into your DAW
  • Interstage Carnhill transformers maintain top-notch sound quality throughout the entire signal chain

Reviews

Amazingly good !
The Rhea is a punchy, versatile compressor that adds energy and presence without sounding over-processed. Its analog character shines on everything. And easily it can be recalled thanks to its memory-friendly controls plugin.
I love it!
I use this compressor on my master bus as part of my mastering chain. So far my clients absolutely love it! It sounds so good! It is super musical and the sound is warm and punchy! In short I love it! I will buy again from Wes Audio, and shout out to my sales rep Ken Nace for helping me get into the world of analogue gear!

Fantastic compressor
So far, we've used this little gem on our lead and background vocal bus, acoustic guitar and mandolin, toms, and on our mix bus. The sound is fabulously warm and fat, with a fantastic sound stage. We've only been using it for about two weeks now, but it's just been a joy to apply to our mixes. I'm sure there are other applications we'll expand into using it for, but for what we've done with it so far it's just fabulous. We've done some A/B testing with the Universal Audio Fairchild emulation and while the differences were not shocking, we picked the Rhea every time. It had a little more presence, a little more warmth, and a little more depth. It was a difference definitely worth paying for! When you add the ability to treat it like a plugin and save your settings - just fantastic.
