The elysia museq matches premium sound shaping capabilities with optimally matched parameters and the highest quality components, enabling users to find musical results quickly and easily. The five bands and their ample gain ranges add flexibly to any tracking or mixing situation.

Each of the two channels offers three parametric bands with a two-position switchable Q. The outer bands per side are low/high shelf, which can be separately switched into a low/high cut mode. In the cut mode, a resonance peak keeps the knee frequency from sounding overly damped, reminiscent of inductor circuits in classic designs.

Each of the five gain controllers per side can be altered from boost to cut with a single switch for easy location of problem frequencies and twice the number of available gain steps. Each channel has a switchable option for adding strong harmonic color of the signal, making two EQs in one. Many prefer the color setting for mix use and the clean for tracking, but as always, let your ears be your guide.

Brainworx, using advanced circuit modeling technology, captures all the color and nuance of the original in this remarkable plugin. They add powerful extras like an integrated M/S matrix for mid and side processing, the possibility to link both channels for more convenient stereo operation, and dedicated output level controllers for adapting your settings to the available headroom.

In addition to the stereo version with all the bells and whistles, a streamlined Mix version is included that lets you get great sounds in a snap.

  • 100% Discrete Class-A emulation

As a true elysia specialty, the museq is completely based on discrete circuitry.

  • Active bandpasses with FETs

The filter stages are completely active and benefit from a puristic design approach for a truly musical EQ.

  • Resonance High & Low Pass Filters

The outer shelving filters can be switched into high and low pass filters, which feature an additional resonance peak.

  • Parallel Filter Design

A special circuit trick makes it possible to leave the high and middle frequencies completely untouched when using the high and low pass filters.

  • Warm Mode

The museq offers a second, switchable sound flavor by altering its frequency spectrum, harmonics, and transient response.

  • Pure Transparency Path

Detailed emulation of the puristic design of the filter stages with current feedback amplifier stages and without any coupling capacitors results in an outstanding sound quality.

  • Boost/Cut Mode

The boost/cut switch generates twice the number of values available, doubling the traditional 23-step potentiometer to 46 steps.

  • Switchable Filter Quality

The filter quality can be switched from wide to narrow Q factors, which remain independent from the gain controller settings.

  • Stepped & Matched Potentiometers

All potentiometers on the museq have 23 steps and are matched to build stereo pairs with a software routine that has been written just for this purpose.

    Museq EQ

    This is, hands down, my favourite EQ, I would put the Mix version across all my channels if I could (CPU permitting), I have a number of nice EQs but for my ears this is the best. It is great… Read More

    Must have for MS
    by Labby
    It seems to be a normal EQ with a wide range of frequencies- but if you look closer you'll find much more than this: correct your side and mid of your stereo source and ad some warm character, if… Read More
