Elysia xfilter Mastering Edition

Elysia xfilter The Elysia xfilter is a high-end Class-A stereo equalizer in a 19” rack format, designed for professional recording, mixing, and mastering applications. Featuring a fully discrete analog circuit and true stereo linking, it delivers precise and musical tonal shaping at the highest level. Its design is based on four EQ bands: two parametric mid bands and flexible high and low bands that can operate as shelving filters or resonant high- and low-pass filters. This versatile architecture allows both precise corrective EQ and creative sound shaping. A standout feature is the additional passive high-frequency stage (“Passive Massage”), which smooths the top end while enhancing clarity and presence without harsh boosting. Sound Character The xfilter delivers transparent, open, and punchy equalization while preserving the natural integrity of the signal. Adjustments are applied with clarity and precision, making it suitable for critical audio work. Resonant filters allow targeted shaping of frequency areas without affecting the entire spectrum. Low frequencies can be tightened and defined, while high frequencies gain a smooth and airy character. Thanks to its true stereo design and carefully selected components, the unit provides excellent stereo imaging and depth accuracy—ideal for bus and mastering applications.

Elysia xfilter 500 The Elysia xfilter 500 is a high-end Class-A stereo equalizer in API 500 format, designed for professional recording, mixing, and mastering applications. As a compact module version of the xfilter, it delivers precise analog EQ processing with maximum flexibility in modern 500-series racks. Its fully discrete Class-A circuitry features true stereo linking, ensuring both channels are processed identically. This results in an exceptionally accurate and stable stereo image—ideal for bus and mastering tasks. The xfilter 500 provides four EQ bands: two parametric mid bands and flexible low and high bands. These outer bands can operate as shelving filters or be switched to resonant high- and low-pass filters. An additional passive high-frequency band (“Passive Massage”) enhances the top end with a smooth, musical character. Sound Character The xfilter 500 delivers transparent, open, and highly precise equalization with clear transient response and solid punch. The sound remains clean and detailed, making it ideal for controlled tonal shaping. Low frequencies can be tightened and defined, while high frequencies benefit from a smooth, airy enhancement through the passive LC filter. Overall, the EQ maintains a neutral and professional character suited for critical audio work.

Elysia xfilter qube The Elysia xfilter qube is a high-end Class-A stereo equalizer in a compact desktop format, designed for professional recording, mixing, and mastering applications. As part of the Qube series, it delivers precise analog EQ processing in a portable and flexible form factor. At its core is a fully discrete Class-A circuit with four EQ bands: two parametric mid bands and flexible low and high bands. These outer bands can operate as traditional shelving filters or be switched to resonant high- and low-pass filters, offering exceptional versatility in tonal shaping. An additional passive high-frequency band (“Passive Massage”) provides smooth and musical enhancement of the top end. Sound Character The xfilter qube delivers extremely transparent, open, and musical equalization. The signal remains natural and detailed, while adjustments are applied with precision and clarity. Resonant filters allow targeted emphasis of specific frequencies without affecting the entire spectrum. Low frequencies can be tightened and defined, while highs gain an airy, refined quality through the passive filter stage. Thanks to its Class-A topology and carefully selected components, the unit ensures excellent stereo imaging with minimal channel deviation and high depth accuracy.
