The Fairchild 670 can perform dynamics processing on the lateral (LAT) and vertical (VERT) components of stereo signals independently. The terms lateral (side-to-side) and vertical (up-and-down) refer to the mechanical modulations in a vinyl record groove that are transduced into electrical audio signals by the phonograph stylus and cartridge. In summary, MJUC is a superb plugin that easily rivals the best high-end compressor plugins on the market, making it another winner from Klanghelm at a ridiculously low price.One of the design goals of the Fairchild 670 hardware was to facilitate its use as a limiter when producing vinyl phonograph masters. In normal usage, the plugin consumed around 10% of one core on our 2.3GHz Core i5 test machine, ramping up to around 30% in HQ mode, which does offer a noticeably crisper transient response, it must be said. On the MkIII, Punch clearly influences release shape, with setting 3 feeling the tightest.Īs for the tone controls, the Timbre control is better at darkening sounds than brightening them, and the Drive, although audible on solo sounds such as vocals and acoustic guitar, is most useful for smearing/smoothing transients. The MkII's IStage option is particularly impactful on bass-heavy sounds and full mixes, which feel considerably more open with it engaged, while Density influences not only gain reduction (there's more of it when engaged) but also transient handling, making the compressor more responsive to them. Having said that, its fast Timing option (1) is pretty good at adding subtle poke to sounds like picked guitar. MkI is at its best gently gluing things together, making a great second insert compressor for acoustic guitar and vocals, and primary compressor for submixes. The three faces of MJUCĮach of the three models offers something a bit different.

All three modes also give access to a foldaway panel containing Dry/Wet Mix, Side Chain Filter and two tone shaping controls: Timbre and Drive.įinally, global options include categorised presets, automatic gain make-up (AGC), 2x oversampling and model accuracy (HQ), level calibration (-24dB to 0dB), channel compression mode (Mono, unlinked Dual Mono and linked Stereo) and meter mode (In, Out, Gain Reduction and input-to-output RMS difference). MkIII retains the Density and IStage options of MkII, but only offers two compression ratios (High and Low), adding a Punch setting, which influences the attack and release.
