SPL BiG Stereo Image Processor Review - 500 Series Module | Tape Op Magazine

tapeop.com

SPL’s BiG Stereo Image Processor impressively redefines stereo imaging with intuitive controls that enhance synths and effects by adding width and character. The Range and Stage knobs provide nuanced control over frequency processing, while the Bass switch compensates for any thinning of the original signal. Its unique character shines on synths and aux buses, offering a "magic fairy dust" touch without overpowering the mix. However, its application on the mix bus can feel heavy-handed, suggesting it’s best suited for specific tasks rather than a catch-all solution. Overall, SPL delivers a standout tool that avoids rehashing old concepts, earning high marks for innovation and functionality.

SPL BiG Stereo Stage Processor – A Real-World Review

mixonline.com

SPL BiG is a stereo widening marvel when used with precision. It's not a tool for the impatient, as it requires careful adjustment to avoid overwhelming the mix. However, when dialed in correctly, it transforms stereo images with impressive depth and presence. While it shines with non-correlated stereo audio, it might not suit all tracks equally, especially those heavily reliant on mono panning or synthetic effects. The key is in the subtlety of its use, making it a powerful asset for those willing to invest the time. Highly recommended for audio purists.
