The SPL Gemini is a pioneering mid/side processor, incorporating the innovative 120V technology to control audio processing precisely. It finds utility in mastering and audio production, offering valuable capabilities for audio professionals.

The Advancement of 120V Technology

In mastering, the SPL Gemini introduces a novel application of 120V technology in mid/side processing. M/S processing offers targeted access to individual elements within a mix, rendering it a valuable tool for audio professionals.

Signal Deconstruction

The Gemini's distinguishing feature is its ability to deconstruct the stereo signal into its fundamental constituents: the "Mid" and "Side." The "Mid" signal encompasses in-phase components like vocals, snare, and bass, while the "Side" signal represents out-of-phase elements like guitars, pads, and cymbals. This separation facilitates precise processing.

Control and Precision

The Gemini permits effortless alteration of stereo width, employing an elliptical filter to transition low-frequency content from the side to the mid, enhancing low-end precision and impact.

Precise Signal Control

The processor provides detailed control over both "Mid" and "Side" signals. Users can fine-tune the centre position with the Balance control and adjust signal levels with the Trim control. The Solo function enables exclusive monitoring of the centre signal, while the Insert buttons facilitate external processor integration.

Optimising the Side Signal

The "Side" signal also boasts a Solo function and a switchable insert for external processing. The elliptical filter enhances bass precision by redirecting low frequencies from the side to the mid. The Stereo Width control allows users to customise the stereo image to their preferences.

Seamless Integration

All inputs, outputs, sends, and returns have balanced Neutrik XLR connectors. The Gemini integrates seamlessly with the Hermes Mastering Router, permitting the creation of processing chains that merge conventional L/R processing with M/S processing.

Gemini and Hermes Collaboration

The Gemini's M/S encoder and decoder stages can be effortlessly integrated into the Hermes, providing unmatched flexibility. Processors between the M/S encoder and decoder handle mid/side signals, with mono devices easily accommodated. This integration facilitates the fine-tuning of processing chains to achieve desired sonic outcomes.

The Power of 120V Technology

The SPL Gemini leverages 120V technology to deliver superior audio quality. Operating at a DC voltage of 120 volts—four times that of conventional semiconductor op-amps—achieves exceptional dynamic range, signal-to-noise ratio, and headroom. This translates to audio experiences characterised by detail and clarity.

Ample Headroom

Compared to devices with lower operating voltages, the Gemini's 120V technology offers substantial headroom, accommodating input levels of +32.5 dBu with a 12 dB advantage. This ensures that all audio components consistently operate within their optimal range, resulting in a pleasurable and fatigue-free listening experience.

Craftsmanship in Germany

The SPL Gemini reflects a legacy of excellence, with SPL's commitment to 120V technology dating back to the 1990s. The technology is the foundation for all SPL premium products, spanning mastering, studio, and hi-fi applications.
