Top 10 Best 500 Series Compressors: Big Buyers Guide 2022!

Top 10 Best 500 Series Compressors: Big Buyers Guide 2022!

Introduction

The need to make a modular rack system with outboard gear prompted the creation of the 500 series rack system within the late 1960s by API. It enabled audio engineers to customize their signal paths with compressors, EQs, and ultimately digital gear on compact, and sometimes transportable rack spaces.

Even at present, the 500 series lets even smaller studios make customized channel strips or effects chains. Larry Droppa, API’s present owner, created the VPR alliance certification. This makes it in order that any 500 series module launched after 2006 is assured to slot in and work with a 500 series rack.

Selecting a compressor relies on methods to maximize its uses, and what sort of sound you’ll wish to achieve. VCA compressors normally manage transients and provide transparency and aggression within the mix. VCA compression is helpful for recording percussion to supply a precise and punchy sound.

Mixing, mastering, and tracking are elements taken into consideration when selecting which kind of compressor is the best suitable for every process. For instance, FET compressors usually are not really helpful to use for mixing and mastering since they produce colorful sound traits.

Since they’re identified for aggressive and fast attacks, they’re extra appropriate for tracking and parallel compression. Then again, an optical compressor is ideally used to compress any sound source naturally resembling vocals, strings, and bass.

We just want to let you know that we’ll list these best 500 Series Compressors in no particular order. They’ll be randomized as we don’t wish to sort them from best to worst.

Listed below are our Top 10 Best 500 Series Compression Units for 2022:

7. SSL 500-Series Bus Compressor MkII

The classic SSL Bus Compressor contains a classic ‘dominant’ sidechain structure. The left and right channels are independently rectified utilizing a real peak full-wave detector circuit, and the dominant (loudest) channel controls the gain reduction of the general stereo level through the user-chosen time constants.

The ‘soft’ knee level of the compressor, ie. the level at which compression begins to happen, is ready by the threshold management (±20dB). That is deliberately designed to alter relying on the setting of the ratio control; reducing the ratio setting lowers the efficient threshold, therefore sustaining the perceived ‘loudness’ of the compressed signal.

The unique console compressor had three ratios (2:1, 4:1, and 10:1), the 500 series model brings three extra intermediate ratios, giving all the unique choices, plus extra 1.5, 3, and 5:1 ratio settings for finer management.

Attack time is switchable in six steps between 0.1 and 30 ms, and the release time is selectable between 0.1 and 1.6 seconds in 5 steps. The Auto release choice adjusts the release time in response to the signal envelope.

The gain makeup acts as level management to compensate for the lowered level that could be a consequence of compressing the signal. This management could also be set in order to not change the general output level when the compressor is switched in.

9. SPL TDx Transient Designer 500 Series Module

Germany’s Sound Performance Lab (SPL) has fairly the pedigree in this space already, having invented the unique “Transient Designer”. Now, they’ve launched the up-to-date TDx: A 500 Series unit with an easy design and lots of impact.

The TDx has solely 4 knobs on the front panel: Attack, Sustain, Mix, and Output, together with a Bypass switch. The key underneath the hood is SPL’s “Differential Envelope Technology” which, in response to the corporate’s website, “permits level-independent dynamic processing by calculating variations in generated envelopes.”

Primarily, this unit is continually monitoring the dynamic envelope of the incoming signal, permitting you to regulate and form the transients and sustain them in real-time.

On kick drum, it may actually carry out the “smack” of the beater, or lengthen the decay of an 808 without merely squashing the track.

The addition of the Mix knob is nice for inline parallel compression, however, we’ve discovered the Output trim is much more helpful, permitting us to add as much attack or sustain as we like without fear of clipping the converters of my hybrid mix rig.

Whether or not you’ve gotten a primarily analog mixing setup, or simply desire a fast and simple transient designer for live or tracking use, the SPL TDx is a good alternative for any application.

10. Lindell Audio 7X-500

The front panel has a delightful type and the knobs and switches really feel elegant. With the 500 modules’ small size, things must be compact and Lindell has packed it in without dropping clarity or logic of format.

This compressor is based around the traditional 1176 design, of input and output level controls, plus variable attack and release instances. Whereas the 1176 has repeatedly variable attack and release, the 7X has three place switches delivering slow, medium, and quick.

Whereas this may occasionally not supply the extreme flexibility of the original, the instances selected work nicely – through the recordings we did not discover ourselves missing something.

Once again, the ratios are a simplified model of 1176. Right here you only have 4:1, 12:1, and 100:1, the latter being the equal of the ‘all buttons in’ choice of its inspiration.

As with the attack and release times, these have been nicely chosen to arm you with loads of choices without compromising the character of the compression on supply.

Operating alongside the above is the ‘Side Chain HPF’, a 3 place switch giving off 100Hz and 300Hz respectively. Whereas 100Hz is widespread, some could think about 300 a tad excessive. In our expertise, although, it delivers a broader scope to the variety of sources upon which it will be helpful.
