Based primarily around the 225L compressor module from API’s highly regarded Legacy Series and Vision consoles, the 527 also included a limited implementation of API’s unique, patented Thrust side-chain filter circuit that defined the operation of the company’s revered rackmount-format 2500 stereo bus compressor. Similar to the Ceiling control in the API 2500 and API 525 compressors, the Auto gain mode fixes VCA gain to unity and allows adjustment of all the controls without the worry of sudden level changes at the output. Circulation is maintained by using pumping ring in running condition and by thermosyphon effect in stand still condition. This stereo compressor features API’s THRUST circuitry for a punchy low end (frequency … All rights reserved. Der API 2500 kann zwar viel, aber eines nicht: dem Anwender Entscheidungen über die zahlreichen Sound-Optionen abnehmen. C52106 This standard is applicable to pressure-relieving and vapor depressuring systems. Umso besser, wenn man sich aus dem Stand bestmöglich zurecht findet! Published: 09/07/2018. Starting at the top, the Meter source switch toggles between reading either the output or input level. API Standard 521 Pressure-relieving and Depressuring Systems SIXTH EDITION | JANUARY 2014 | 248 PAGES | $275.00 | PRODUCT NO. Parallel compression and M-S modes might have been nice. To find B o, R s has to be calculated first, from Eq. I'm enjoying my new 527s, they totally live up to the 2500. Switching to Old Type on the same vocal made it smoother and less rigidly strict—it is great to have several choices in these situations. This stereo compressor features API's patented THRUST® circuitry for a punchy low end, along with an Old/New switch that lets you choose between classic and … The circuit boards use surface mount technology throughout, and the control pots and switches are solidly connected to the boards, with the pot shafts and toggle arms extending through holes in the front panel. The last of this tonal triumvirate, Thrust, gives you access to three side-chain filter settings (loud, medium and normal), of which more in a moment. To me, the main strength of all the API products that I’m familiar with is their ability to deliver a clean, clear, tight, balanced and musical sound, with a high level of transient detail across the audio spectrum — and the 529 certainly doesn’t disappoint in this respect, even when compressing heavily. One advantage of this type of detector is that, because the summing takes place after detection, the resulting control signal is unaffected by phase, polarity or differences in L-R level and stereo content. The API 529 delivers API’s unmistakable warmth, clarity and punch in a flexible small two-slot 500 series module. Posted on: Tuesday 13th of February 2018. This system allows for a seamless, noise-free transition into compression without the bypass relay making/breaking the signal path momentarily. Our products are manufactured and tested in accordance with respective API, ASME, and ANSI standards. The API 529 has most of the same circuitry, including the patented THRUST sidechain filter circuit. In this article. Operation, especially in the automatic make-up gain mode, was pretty much intuitive once I’d familiarised myself with the effects of the various possible mode combinations. Web site designed & maintained by PB Associates & SOS. Something like a dynamic equalizer, the 529 smoothed out the abrasiveness of this mix, kept the low frequencies tight, and I was able to EQ freely post-compression. Great care has been taken to ensure accuracy in the preparation of this article but neither Sound On Sound Limited nor the publishers can be held responsible for its contents. Oddly, the silk-screened values for the Attack and Release do not match the maximum 31st detent position of these two controls. While in bypass mode, the meter automatically locks to reading input. Ingeniously, the final Out switch not only switches the compressor in and out of circuit, but also allows you to switch between a soft bypass (in which the 529’s circuitry remains in the audio path) or a hard, relay-switched bypass, which removes the module from the signal path entirely. Most hardware compressors are fixed knee, or allow switching only between hard or soft knees. Next in line come three switches, taken straight from the 2500, which determine the operation, and thus the sound, of the 529. Similar to the Ceiling control in the API 2500 and AP… It really is rather special! Surprised there are no other reviews on this beast! Anyone can submit a proposal for a new standard. For instance, here you can examine Neon CRM (overall score: 8.1; user rating: 100%) vs. Little Green Light (overall score: 8.7; user rating: 97%) for their overall performance. Based on the unprecedented success of the 2500, the 529 takes many of the features and controls from API’s famous stereo compressor and puts them into their first dual slot 500 Series module. Vibes for days and stereo imagineg is unbeatable!!

Its dual channel design lets the 2500 also function as two separate mono channels via a single compression setting. A small red LED indicates that the incoming signal is above the Threshold control knob setting. For stereo bus compression I found either Medium or the Loud THRUST settings worked well for an aggressive overall sound on overly bright mixes. I used the New Type for clean, strict and tight control of my overly dynamic singer. The medium and, especially, the loud Thrust modes were a revelation; their effect is, as far as I’m concerned, worth the price of admission on their own. Position 3 is called Loud, and the curve changes to a gradual linear shape that is -15 dB at 20 Hz and rises to a +15 dB boost by 20 kHz. Find the crude oil volume that will be measured at the surface in the stock tank. The "standard" API products like the 512c Mic Preamp, 525 Compressor, the 550A and 550b EQs continue to win listening tests, technology awards, and new fans, while the "newer" products such as the 512v Mic Preamp, 2500+ Bus Compressor, the 527 and 529 Compressors and the phenomenally successful AXS, 2448, 1608, and THE BOX consoles demonstrate just why API … The THRUST filter is placed first in line before the RMS detector and has three very specific filter curve choices. Instantly recognisable as an API product, the 529’s black and blue fascia enjoys a sense of spaciousness, with LED displays, switches and indicator LEDs occupying the height and width of the left half with rotary control knobs on the right. Depressurised buffer fluid circulation in outboard seal of a dual seal configuration through a seal support system. On the other side of the central divide sits the column of five 31-position, detented, continuously variable rotary control knobs that provide instant access to the usual compressor controls of Make-up Gain (0-24 dB), Threshold (+10 to -20 dB, with an LED that flashes red when the threshold is exceeded), Attack (1 to 50 ms), Ratio (1.5:1 to Inf:1) and Release (0.05 to 4 seconds). Although the two channel inputs are transformerless, the outputs are balanced by reassuringly chunky transformers. Update your browser to view this website correctly. If you’re in need of a 500‑series stereo bus compressor and have the budget available — and can live without built-in M‑S processing and parallel compression modes — then the API 529 should be sitting at, or very near to, the top of your audition list. Save 5%, MSRP $3170.00 Be the first to write a review. Also, since, like human hearing, RMS detection is more sensitive to average signal levels, the resulting compression tends to produce a more natural-sounding result. Many states offer tax benefits to residents who invest in local plans. All contents copyright © SOS Publications Group and/or its licensors, 1985-2021. Your first stop in shopping for a 529 plan is to look at what your state has to offer. Based on the unprecedented success of the 2500, the 529 takes many of the features and controls from API's famous stereo compressor and puts them into the first dual slot 500 series module from API. This would be the typical way to toggle the API 529 in and out. 529 Reviews Sort By Date Sort By Rating Write Your Review. From top to bottom are: Gain (Make Up from 0 to +24 dB), Threshold (+10 to -20 dB), Attack (1 to 50 ms), Ratio (ranges from 1.5:1 to ∞:1) and Release Time (50 ms to 4 seconds). Herzstück der Bedienelemente sind die typischen Einstellparameter eines VCA-Kompressors: Threshold, Attack, Release, Ratio. Chaz Hurwitz from San Francisco, CA. When the Tax Cuts and Jobs Act was implemented, it changed the rules around 529 plans. The PCBs occupy all but a couple of millimetres of the available height inside my rack, with the side of the right-hand transformer’s coil sitting just inside the module’s width limit. API have made compressors for the 500‑series format for a very long time — the 525 first became available way back in the 1970s! api 510 10221 10871 11300 12290 13424 13946 14992 14663 15559 15936 16117 api 570 9116 9806 10259 10840 11767 13009 13519 13804 14311 14652 15176 api 653 6162 6440 6713 6945 7374 7787 7986 7995 8333 8228 8452 api 936 964 1051 1173 1232 1326 1409 1533 1551 1784 1885 1931 tes 631 629 626 658 678 673 680 649 646 616 590 api 571 416 481 595 707 878 988 1147 1211 1362 1411 1461 api … Position 2 is Medium, and the curve has a low-frequency roll-off of 3 dB per octave starting at 200 Hz and a 3 dB per octave boost starting at 4 kHz and continuing to 20 kHz. This stereo compressor features API's patented THRUST circuitry for a punchy low end, along with an Old/New switch that lets you choose between classic and modern … If your state does not offer tax breaks or you’re interested in better options, you can start looking at some of the best 529 plans … Using the Loud THRUST position will compress more on the S’s and fricatives and may require re-adjusting Attack and Threshold. Again, two disparate acoustic tracks ended up sounding like one player performed the guitar part all in one go, and there was no loss of treble in the guitar sound.
