Balance Analog Magpha EQ plugin

True analogue phase mastering/buss equaliser

The Balance Mastering 'Analog Magpha' EQ plugin.

A plugin EQ to rival analogue hardware

We wouldn't release a mastering equaliser unless it rivalled the sound and usability of the analogue hardware we have in our studio. But we are now ready with the Analog Magpha EQ.

This EQ is the result of years of mastering experience and has been a secret weapon in getting exactly the right sound for our clients. We hope it can help you too, whether placed on a track, subgroup or the master channel, this EQ delivers a silky smooth sound that's as warm as it is pure.


  • Sound
    • Very open, smooth sounding curves.
    • True analogue phase behaviour right up to 20000Hz.
    • Optional very broad Q factors (<0.1), great for final wideband tone sculpting.
  • Technology
    • Extremely accurate match of analogue prototype curves in magnitude and phase.
    • Low latency performance.
    • Windows, Mac and Linux version available.
  • Interface
    • Minimal, zero-eye-candy interface reinforces the use-your-ears approach.
    • Stepped controls, carefully chosen to aid comparisons and guide decision making.
    • Stereo/Mid/Side band modes for full stereo field control.
  • Filters
    • 6 peaking filter bands.
    • Low & high shelves with extended frequency ranges.

True analogue phase

Under the hood we've developed a new technology that gives extremely accurate match of analogue prototype curves in both magnitude and phase. While most modern digital EQs do a good job at matching the magnitude of analogue filters, they do not match the analogue phase.

The lower panel shows that Analog Magpha EQ matches analogue phase right up to 20kHz, even at standard sample rates. This is often perceived as an "open", "pure" sound which is prized in analogue hardware by many engineers, especially when a few bands of mid or high frequency EQ is engaged.

Use-your-ears interface

We believe that key to creating great sounds is to use your ears. That's why our user interface is fully designed to reinforce the feedback loop between control and ear.

As engineers, it is easy to be distracted by visual feedback (consciously or unconsciously). Our UI design has minimal graphic elements, so that we don't dial in "shapes" by habit. This way we are constantly involved in the control-listen-evaluate working loop, which quickens the search for the best possible sound.

For the technically inclined, we presented the new technology that this plugin is based upon, with accompanying peer-reviewed paper at the Audio Engineering Society's Milan 2018 event: Improving the Frequency Response Magnitude and Phase of Analogue-Matched Digital Filters
