Description

The SPL PQ Mastering EQ (All Black) is a high-end dual-channel parametric equalizer designed for mastering engineers who require precise control and exceptional sonic transparency. Built as a fully independent dual-mono unit, it can be used for detailed stereo processing or to treat two separate mono sources, offering a flexible approach to shaping sound in professional mastering environments. Its clean layout and stepped controls make it easy to dial in exact settings and return to them with confidence, supporting consistent results across sessions.

Each channel features five fully parametric bands with wide, overlapping frequency ranges, allowing for both surgical corrections and broad tonal shaping. The ability to switch between constant Q and proportional Q modes gives users control over how the equalizer responds, making it suitable for both corrective work and more musical adjustments. Fine-tuning is further supported by stepped gain controls and a reduced gain range option for subtle changes, helping maintain precision without over-processing the signal.

At the core of the PQ is SPL’s 120V technology, which provides exceptional headroom and clarity, allowing audio to remain open and detailed even during demanding processing. Combined with features like auto bypass for objective comparisons and link functionality for stereo operation, the PQ Mastering EQ (All Black) offers a refined and reliable tool for critical listening and tonal shaping in mastering workflows.
