Elysia XFilter

What is the Elysia XFilter?

The Elysia XFilter is a handcrafted analog stereo 4-band equalizer built on clean Class-A circuitry, designed for precise, musical tone shaping on tracks, buses, and masters. It pairs two parametric mid bands with switchable high/low shelves, resonant cut filters, and a unique “Passive Massage” air circuit, all controlled in true stereo. Engineers reach for it when they want surgical precision with an open, modern, high-fidelity sound.

What is the Elysia XFilter best for?

The XFilter is best for clean, precise EQ across mastering, mix-bus, and individual tracks – adding clarity, sparkle, and dimension without heavy coloration. Its resonant filters make it great for punchy drums, tight bass, and vocals that cut through, while the true-stereo design suits mastering and stereo-bus work. Reach for it whenever you want transparent, surgical tone shaping rather than vintage character.

What bands and filters does the XFilter have?

The XFilter is a four-band EQ: two fully parametric mid bands with a switchable wide/narrow Q, plus high and low bands that can act as shelves or as resonant high-/low-cut filters. It also includes the separate “Passive Massage” high-frequency circuit, and its controls are stepped and matched for true stereo operation and reliable recall. The bands overlap across a very wide frequency range, so you can shape almost any source.

What is the “Passive Massage” feature?

Passive Massage is a one-button, fully passive high-frequency circuit that adds air and sparkle to the top end. Built from a shielded inductor-capacitor (LC) network, it places a gentle resonant lift around 12 kHz with a smooth roll-off starting near 17 kHz. The result opens up and sweetens the highs while taming harshness, without boosting the entire treble range.

How do I use the XFilter’s resonant high- and low-cut filters?

Switch the high and low bands from shelf mode into cut-filter mode, and their gain control becomes a resonance control at the cutoff frequency. Use the low-cut to clean rumble from bass and kick while a touch of resonance adds punch at the fundamental, and use the high-cut to darken bright sources while keeping presence. Adding resonance at the cutoff is a fast way to make drums punchy, bass tight, and vocals pop.

What’s the difference between a passive EQ and an active EQ?

An active EQ uses powered circuitry to boost and cut directly, which allows precise, surgical moves and clean gain. The approach behind the XFilter’s four main Class-A bands. A passive EQ shapes tone with only passive components (inductors, capacitors, resistors) and tends to sound smooth and musical, but needs a separate make-up gain stage. The XFilter is primarily an active design, with one passive LC stage, the Passive Massage, for that classic high-end sheen.

Is the Access Analog Elysia XFilter real hardware or an emulation?

It is the actual Elysia XFilter – a real, handcrafted analog EQ with genuine Class-A circuitry, not a software model of it. Through Access Analog, the Analog Matrix plugin robotically controls the physical hardware in real time from inside your DAW, so your audio runs through the real circuit. Real Gear. No Emulations.

Can I recall and automate my XFilter settings through Access Analog?

Yes. Every control on the Analog Matrix plugin is robotically linked to the physical hardware, so you can save, recall, and automate your settings inside your DAW session like any other plugin. Because the XFilter uses stepped, matched potentiometers, recall is precise and repeatable, your exact band, frequency, and filter settings come back every time, on real analog hardware.

How much does it cost to use the XFilter at Access Analog?

The Elysia XFilter reserves from $3.30 per hour, an affordable way to put a high-end Class-A EQ on your mix or master. Reserve a session on the calendar or use it on-demand with credits or an active subscription (subscriptions start at $9.98/month), and new accounts get a free hour (about 12 credits) to try real hardware.
