Midas

Smooth out your performance with the highly dynamic Midas 522, a 500-Series compressor limiter with a fully variable and dynamic presence control for preserving high to midrange frequencies for a more natural sound. Adding compression to your signal ensures a rich, dense, and impactful sound.Note: This is a 500-Series module that requires a 500-Series rack enclosure (sold separately) to provide power and analog input and output. The module will not operate without an enclosure.Benefits Compact 500-Series premium compressor/limiter with dynamic presence controlFully variable dynamic presence feature preserves high midrange frequencies for a more natural sound during compressionDynamic presence control adds air to vocals without introducing noise or pumping effects and reduces the risk of feedback during live performancesManual envelope controls with linear peak-sensing compression or easy-to-use Auto mode with RMS compressionSoft or hard-knee compressor response with selection switchSide-chain high-pass filter with selection switch eliminates undesirable low-frequency compression artifactsHigh-performance electronically balanced input stage with high common-mode rejectionHigh-power balanced output drives long audio cables with easePrecision gain reduction and signal level meteringTrue hardware bypass selection switch removes all circuitry from the signal path when compression is not requiredPower up mute relays prevent switch on thumpsPremium quality components throughout for a crystal-clear audiophile signal pathImportance of Dynamics Dynamics are the essence of a natural sounding performance and is what makes music interesting. Out-of-control dynamics can instantly mar an otherwise perfect performance. That is where compression comes to the rescue, softening loud sounds and boosting low signal levels that can often get lost in the mix. The resulting compressed signal creates a much more dense and impactful sound, with richness, and room for subtle nuances to come through.Variable Dynamics and Air The range of mid-high audio frequencies (centered around 5 kHz) can be boosted to increase the sense of presence of vocals and solo instruments. As 522 s Presence control is adjusted above minimum, those mid-high frequencies are increasingly boosted during compression, allowing a sound or instrument to cut through or seem more present in the mix. This variable presence function enables the 522 to effectively operate with two different ratios, one for low frequencies (LF) and the other for mid-high frequencies (reduced ratio). The primary effects are heavy compression and dynamic control, and can be applied without sounding unnatural. The reduced compression in the human ear s most sensitive range makes the material sound brighter. However, since high-frequency (HF) makeup gain is not required, unwanted noise, pumping, and howl that sound during quiet passages are all greatly reduced.Manual or Auto Modes When operating in its default mode (Auto switch not engaged), the 522 functions as a peak-sensing compressor, providing tight peak control via instantaneous changes in gain reduction, which produces more obvious compression. This allows the operator to manually adjust the compressor attack and release times, so the compressor operates in peak mode with linear attack curves. When the Auto switch is engaged, the manual attack and release controls are bypassed, and the compressor operates in RMS mode, automatically adjusting the attack and release based on the average input signal and the threshold/ratio settings. This produces a smooth, more relaxed compression that is perceived as more musical and natural sounding.Soft or Hard Knee Another element that affects how natural the output sounds when compressed is how the signal is addressed at and around the knee, or threshold point.By default, the 522 is set to Soft-knee compression (switch out), which tends to sound more natural as it blurs the distinction between over and under
