This makes the input more resistant to overload by hot signals. After the input transformer, the signal is attenuated by the same gain reduction FET as in the MC77. The attenuated signal is buffered by our class A KDJ3 opamp, which feeds the output fader. Lastly, our class AB KDJ4 output opamp drives our custom hexafilar nickel and steel output transformer. The total gain (with no attenuation) is 45dB, just like the MC77. \u003cbr\u003e\u003cbr\u003e The attack and release times cover a broader range than the MC77, which can cause distortion... which may or may not be what you are looking for.

The link is accomplished using a XLR-F to XLR-F cable with pin 2 on one XLR-F connecting to pin 3 on the other XLR-F and vice versa. Plug in the cable, flip the front panel switch and you are linked. Non-Purple racks do not have an easy way to connect pins 3 and 6, and will need modification to link two Action units. \u003cbr\u003e\u003cbr\u003e The  \u003cb\u003eSpecifications:\u003c\/b\u003e \u003cli\u003e Total Gain: 45dBu \u003c\/li\u003e\u003cli\u003e Ratios: 4:1, 8:1, 12:1, 20:1, ∞:1 (\"All buttons in\") \u003c\/li\u003e\u003cli\u003e Attack time: Continuously Variable from over 800 microseconds to 20 microseconds \u003c\/li\u003e\u003cli\u003e Release time: Continuously Variable from over 1.1 seconds to 50 milliseconds \u003c\/li\u003e\u003cli\u003e Input impedance: 600 ohms \u003c\/li\u003e\u003cli\u003e Output impedance: 600 ohms \u003c\/li\u003e\u003cli\u003e Current consumption: 90ma \u003c\/li\u003e","brand":"Purple Audio","offers":[{"title":"Default Title","offer_id":44449236189287,"sku":"9158","price":825.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/purple_audio_action_fet_1.jpg?v=1787088255"},{"product_id":"purple-audio-pants","title":"Purple Audio Pants 500 Series Microphone Preamp","description":"The \u003cspan style=\"font-weight: bold;\"\u003ePurple Audio Pants\u003c\/span\u003e uses a unique dual-bobbin input transformer from Cinemag unlike any other.

Traditional wisdom holds that linear power supplies are ideal for audio and generate less noise and interference. In many cases, especially with poorly designed \"off the shelf\" switching power supplies, this is true. However, in the case of a 10 slot series 500 rack, even a well designed linear power supply generates a substantial magnetic hum field and far too much heat to allow for internal mounting. This problem is caused in part by the wide variation of line voltage across the world. External power supplies are cumbersome and inconvenient and consideration still has to be taken as to their placement in relation to other equipment.\u003c\/p\u003e\r\n\r\n\u003cp\u003eWith the advancement of switching power supplies it is now possible to have a switcher that does not compromise audio performance and delivers or exceeds all specified current needs.

Now, after considerable research and development, the \u003cstrong\u003eA Designs Audio EM-PEQ\u003c\/strong\u003e has captured the essence of the highly revered Pultec EQP-1A and placed it in the compact and popular 500-Series form - with no compromise in sonics or build quality. Along with modern performance enhancements, the A-Designs Audio EM-PEQ meticulously maintains the EQ-section design and control layout of the original Pultec EQP-1A, as well as its wonderfully smooth musicality. It also has the same frequency settings and inductors that made the Pultec a must-have for capturing the bottom end. Makeup amplification is achieved through the use of the same discrete Class AB amplifier found in A-Designs Audio’s immensely popular solid-state Pacifica mic preamp—putting a slightly unique and modern twist on the classic design of yesteryear.   \u003c\/p\u003e\r\n\u003cp\u003eThe EM-PEQ’s controls attenuate high band at 5, 10, 20 kHz; vary bandwidth AND boost mid to high band at 3, 4, 5, 6, 10, 12, 16 kHz; and boost or attenuate the low band at 20, 30, 60, or 100 Hz.

As a de-esser in the DS mode (HF Limit OFF), one can set the threshold to tame harsh S’s (sibilants) that result from an overly bright singer or from EQ’ing to make a vocal sound aggressive and clear. In this mode, the dyamic action is “level insensitive”, as the detector circuitry compares the High Frequency content to the low frequency content.  Overall signal level doesn’t matter at all. When there is enough HF compared to LF, the threshold is exceeded and the DerrEsser starts to turn down the frequencies above the crossover point set by the Frequency control on the front panel. Again, great care was taken to ensure this DS section meets the Empirical Labs reputation for originality and ease of use.  We use the latest technology VCA, specially selected for glitch free, distortion free, and noise free performance.  The time constants were carefully selected and the corner frequency is user adjustable with a high performance active crossover. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHF Limit\u003c\/strong\u003e – (Bypass Button IN, HF LIM IN, all other buttons OUT).  In this mode, the DerrEsser looks at the general level of the high frequencies only.  Think of it as a high frequency compressor. If there is enough high frequency content to exceed the threshold, then gain reduction occurs.  It is level sensitive, but responds much more to high frequencies. This mode can also act as a de-esser but is more of a general high frequency smoothing device.  The HF limiter is probably the first carefully tailored soft knee HF limiter in existence. We believe both the DS and HF LIM modes offer the highest performance of any similar device. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHighpass\u003c\/strong\u003e – (Bypass Button IN, Listen IN, HP\/LP OUT, HF LIM doesn’t matter). By using the “LISTEN” Function, the user can employ the superb filter circuitry inside the DerrEsser to process their audio.  With the LISTEN button IN, and the HP\/LP switch OUT, the user will be hearing the high frequencies that are being controlled with the dynamic\/compression circuits.  The corner frequency is adjustable by the Frequency knob. Once the LISTEN switch is engaged, all bargraph LED’s should light as indication. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eLowpass\u003c\/strong\u003e – (Bypass Button IN, Listen IN, HP\/LP IN, HF LIM doesn’t matter). With the LISTEN button IN, and the HP\/LP button IN, the user is now listening to the low frequencies, those not affected by the VCA and dynamic\/compression circuits.  This is a 12 dB per octave filter whose corner frequency can again, be adjusted by the Frequency knob. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUsing for the first time\u003c\/strong\u003e\u003cbr\u003eThe DerrEsser is not only a high frequency problem solver, but can be used as a super-quality HP or LP filter, AND as a coloring device to give a more analog sound to digital sources.  Use the DerrEsser when you have a vocalist with prominent unnatural “S’s.  The standard DS Mode is usually used, with the Frequency set to 2 – 6K.  Adjust the threshold till the S’es are tamed and not much else is affected.  The HF Limit will more generally smooth the high frequencies, gently subduing high frequencies that exceed the user adjusted threshold. Great on so many sources. \u003cbr\u003e\u003cbr\u003eThe DS Mode can also help difficult problems like high hat bleed in the snare mike, or occasional SQUEEKS on an acoustic guitar or other instrument.  See example settings.  The HF Limit Mode is a general high frequency smoothing setting.  Use it to soften the high end on zillions of sources, not just vocals.  If you have a track that has high frequency spikes, or plucks, or edges, this can let you keep the air of the high end except when it really piles up.\u003c\/p\u003e","brand":"Empirical Labs","offers":[{"title":"Default Title","offer_id":44449237467239,"sku":"9889","price":475.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/empirical_labs_derresser_elds_horizontal.jpg?v=1787088260"},{"product_id":"bae-11-module-500-series-rack-mount-with-psu","title":"BAE 11 Module 500 Series Rack Mount with PSU","description":"\u003cp\u003eThe \u003cstrong\u003eBAE 11 Module Rackmount with PSU and 48V Phantom\u003c\/strong\u003e Features:\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eStrong steel chassis - not aluminum\u003c\/li\u003e\r\n\u003cli\u003eShielded wires on individual connectors for serviceability- no PCBs\u003c\/li\u003e\r\n\u003cli\u003eXLR inputs and outputs\u003c\/li\u003e\r\n\u003cli\u003eRemote power supply keeps power transformer interference away from modules\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp\u003e\u003cstrong\u003ePower Output\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e+\/- 16 VDC 1.6A\u003c\/li\u003e\r\n\u003cli\u003e48VDC .1A\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003ePower Requirements\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e115\/230 VAC, 36W\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"BAE","offers":[{"title":"Default Title","offer_id":44449237500007,"sku":"9547","price":1250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/bae_11_module_500_rack_w_psu.jpg?v=1787088260"},{"product_id":"lipinski-l-629-compressor","title":"Lipinski L-629 Compressor","description":"\u003cp\u003eThe \u003cspan style=\"font-weight: bold;\"\u003eLipinski Sound L-629\u003c\/span\u003e 500 Series compressor’s basic principle of operation and ballistics is based on the famous Fairchild Compressor as its extremely fundamental design is rooted in the patented “Lipinski Square” circuitry.

The \u003cstrong\u003eMono Optograph's\u003c\/strong\u003e front end is balanced by an original Jensen input transformer. The output utilizes our specially recreated Nickel transformer. The essence of the compressor's character comes from our custom electroluminescent cell and discrete op-amp combination. The high quality circuit is pristine enough for bus compression, and yet has a unique character reminiscent of an antique world class compressor, that has just now been discovered. It's also perfect for squeezing drum busses and massaging vocals. It's the perfect glue for tracking and mixing anything that needs to sound more finished, more like a record. \u003cbr\u003e\u003cbr\u003eJust like The Mastering Compressor, the Optograph's threshold and make up gain are controlled by discrete attenuators, made from custom twenty-four position Elma switches. The tactile feel and quality of these controls are unrivaled. They are of the highest quality and will last forever. \u003cbr\u003e\u003cbr\u003eBuilt into the side chain, are a very powerful series of filters: 90 hertz, 150 hertz, 250 hertz, and band pass. By engaging a specific filter, you choose at which point the onset of compression occurs. First position, nothing below ninety triggers compression. Second position, nothing below one-fifty. Third, nothing below two-fifty. The fourth position is a musical bandpass filter. In this position, compression is triggered by the program's mid-range frequency content, ignoring the highest and lowest frequencies. The filters are amazingly useful for shifting the focus of what should be more compressed and creating compression curves on purpose. \u003cbr\u003e\u003cbr\u003eAnother unique feature for sculpting the overall sonic character is the Transformer Desaturate mode. In this mode we cancel out any distortion and frequency non-linearity’s caused by the output transformer.
