MQ55 is parametric equalizer designed for mixing stage of music production.

The larger part of interface consists of seven modules (labeled LSF, LF, LMF, etc.). The first and the last are lowshelf and high-shelf, while inner five are peak filters. They all have ±12dB operating range when ratio knob is in default position. Ratio knob controls multiplying factor for all filters. For example, when it's at maximum position (3:2) every gain is multiplied by 1.5, so +6dB becomes +9dB, and -8dB becomes -12dB. You should use it after you've set all other parameters to adjust overall amount of equalization (kind of dry/wet control). Monitoring button (MON) activates isolation of each peak filter while you adjust it's frequency. Frequency controls are divided into seven overlapping zones that cover every useful part of spectrum. LSF and LF as well as HF and HSF share those zones, but since they are different types you’ll get different results out of them. Above them are located displays with numerical readouts showing current frequency or filter gain amount. Q factors are controlled with lower row of knobs, five of them being blue, two being green. Shelf and peak filters have Q factors that do not act the same, although they share the same principle of higher Q meaning steeper curve. On the bottom there are on/off switches for each filter. Use CTRL+mouse for precise adjustment of each knob and double-click to reset them to default position.
  • 7 parametric minimum-phase stereo filters, 5 of them are peak, 2 are shelf.
  • Functions and ranges optimized for mixing tasks.
  • HP and LP filters with two selectable slopes (1st & 2nd order for HP, 2nd & 4th for LP filter).
  • Ratio knob that serves as a overall gain multiplier.
  • Possible monitoring for each peak filter.
  • 32-bit internal precision with zero latency and low CPU consumption.
  • No introduced harmonic or dynamic distortion.

Not very accurate or flexible but the sound quality seems good. CPU usage is medium to high.

A precise and no nonsense unit which can really do wonders on your final mixdown. Leave all the Q widths at 1db per octave for a classic graphic EQ response. One of the best free mastering tools in my collection!

Incredible, thanks so much!! I've been using PQ33 for 4 months now, but it wasn't as precise as MQ57, so I used both of them and wished there was something that would combine their best sides and here it is! Love the design and responsive controls of those two and I'm sure this one will become my favorite!
