WesAudio RHEA NG500 500 Series Stereo Vari-Mu Tube Compressor

The WesAudio _Rhea NG500 is a 100% analog, true stereo vari-mu tube compressor that brings the rich, musical character of classic feed-backward tube compression to the 500 series format. High-voltage tube gain reduction is paired with interstage CARNHILL transformers, which not only smooth the signal but add a fuller, more pronounced low end — delivering the warm, glue-like compression vari-mu designs are famous for, with +24dBu of headroom and frequency response extending to 150kHz.

Beyond input and output level controls, _Rhea features a Mix knob for instant parallel compression, a switchable THD circuit (Medium and High modes) for adding analog saturation and harmonic colour, and three sidechain high-pass filter options (60Hz, 90Hz, 150Hz) to keep low-end content from triggering unwanted gain reduction. A hardware A/B function lets you instantly compare two settings at the touch of a button.

What sets _Rhea apart is its digital control layer wrapped around a fully analog signal path: total recall and plugin control via VST2, VST3, AU, AAX, and AAX DSP, four touch-sensitive encoders for recording automation directly into your DAW, and full compatibility with both standard 500-series racks (via front-panel USB) and WesAudio’s _Titan ng500 chassis for unified session recall across an entire rack. True bypass and a precise analog GR meter round out a module built for engineers who want vintage tube tone with modern studio workflow.

WesAudio is a Polish audio manufacturer based in Szczecin, founded in 2010, known for building professional analog outboard gear that bridges classic tube and transformer-based circuit design with modern digital convenience. Their flagship ng500 series — including modules like _Rhea, _Calypso, _Dione, and _Mimas — pairs fully analog signal paths with total recall, DAW plugin control (VST/AU/AAX), and automation, all accessible via USB or through their _Titan rack chassis for unified control of an entire 500-series setup. The company’s focus is on giving engineers genuine vintage-style analog tone without sacrificing the recall and automation workflows expected in modern digital studios.
