The Elysia xfilter qube is a compact, desktop‑friendly version of the renowned xfilter 4‑band stereo equalizer, designed to bring mastering‑quality analog EQ into mobile setups, project studios and on‑the‑go workflows. Housed in Elysia’s robust qube enclosure with an integrated high‑quality power supply, the unit delivers the same transparent, open‑sounding EQ character as its 19" and 500‑series siblings, but in a portable, stackable format.
 
Inside, the xfilter qube features a 100% Class‑A discrete topology with true stereo‑linking, ensuring that both channels track perfectly and maintain a stable, coherent stereo image. The EQ offers four bands: high and low shelf filters, resonant high and low‑pass filters, and two fully parametric mid bands with switchable Q, giving you surgical control over the entire spectrum from the mix bus down to individual tracks. An additional passive high‑band lets you add subtle air and presence without introducing coloration, making it ideal for mastering‑style refinements.
Precision is key: the unit uses 41‑step computer‑selected potentiometers together with ultra‑tight‑tolerance components, guaranteeing repeatable, stable settings across sessions. With a frequency range below 10 Hz to 400 kHz, low noise (‑98 dBu), 120 dB dynamic range and +21 dBu headroom, the xfilter qube provides the sonic headroom of a high‑end studio EQ in a desktop‑friendly chassis. Line‑level XLR and 6.3 mm jacks round out the connectivity, while the compact aluminum enclosure fits neatly beside a laptop or in a travel rack.
 
For engineers, producers and mobile mastering engineers seeking a portable 4‑band stereo analog EQ with Class‑A transparency, true stereo‑linking and mastering‑grade precision, the Elysia xfilter qube is a powerful, compact solution for analog tone shaping wherever you work.
