Description

Unleash the full potential of your mixes with the SPL BiG Studio Stereo Image Processor, a powerhouse in audio dynamics and stereo imaging. Designed for both seasoned professionals and ambitious producers, this 19-inch rackmount device is a game-changer in the realm of sound enhancement. Equipped with a unique vacuum tube circuit, BiG Studio not only broadens your stereo image but also infuses your sound with vibrant, larger-than-life harmonics. This isn't just stereo processing—it's a redefinition of what stereo can be.

At the heart of BiG Studio is an intuitive control set. The Range control lets you select the frequency range to process, while the Stage control moves these frequencies forward or backward in the soundstage. Want to add a touch of boldness? The Bigness knob allows you to adjust the intensity of your processing with finesse. Furthermore, the Harmonics button activates a tube circuit, injecting vivid harmonics into your sound, with a Tube Harmonics control to customize the effect to your liking. The Bass button introduces a passive bass boost, inspired by SPL’s renowned Iron mastering compressor, for an enveloping low-end presence.

Built with durability in mind, BiG Studio features a 4mm-thick, black anodized aluminum front panel and robust knobs crafted from aircraft-grade aluminum. The internal audio voltage of ±18V ensures pristine sound quality and high headroom, while gold-plated Neutrik XLRs and TRS jacks provide reliable connectivity. With SPL’s German engineering excellence, this processor not only sounds great but is also built to last.

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.
