The Tube-Tech CL 1B MkII plug-in, developed by Softube for UAD hardware and UA Audio Interfaces, is an enhanced emulation of the iconic optical compressor renowned for its smooth, warm sound. This compressor has been favored by leading pop, hip-hop, and R&B artists, delivering a signature tube character that adds richness and depth to vocals as well as other instruments. The MkII update brings sonic improvements and high-resolution graphics, capturing the compressor’s classic tone with greater clarity and authenticity.

This plug-in offers a modern take on a studio staple, featuring selectable attack and release settings that adapt to a wide range of audio sources. Whether gently smoothing vocals or adding punch to drums and guitars, it provides dynamic control that enhances the natural transients and musicality of the performance. The addition of Parallel Compression and Sidechain Low Cut controls increases its flexibility, allowing users to blend compressed signals with the dry source and maintain clarity by filtering out low frequencies from triggering compression.

Alongside its refined sound, the Tube-Tech CL 1B MkII boasts an updated interface with bold, high-resolution graphics optimized for 4K and Ultra HD displays. This visual upgrade complements the plug-in’s professional-grade features, making it a reliable choice for producers and engineers aiming to infuse tracks with the smooth, tube-driven compression beloved by numerous chart-topping artists.
