Incorporating the   517?s powerful preamp, the 5012?s universally useful sweepable high pass   filter, and the transformer-saturating power of a variable silk circuit   derived from our flagship Portico II Channel, the 511 is a Rupert   Neve-designed mic pre for the masses.\u003c\/p\u003e  \u003cp\u003e\u003cb\u003eDesigned for 500 Series by Mr. Rupert Neve\u003c\/b\u003e\u003cbr\u003eRupert   Neve: “While creating functional 500 Series modules is relatively   simple, designing those modules to equal their non-500 Series   counterparts with the current, voltage and space restraints is quite   challenging. In creating our Portico 500 Series modules, we experimented   with a number of different transformer and circuit designs to achieve   the same presence and sweetness found in the Portico Series of modules.   The result of these efforts is that outside of the slightly lowered   headroom, our 500 Series modules are nearly indistinguishable from   standard Portico Series modules, and are perfectly suited for studios of   the highest caliber.”\u003cb\u003e \u003c\/b\u003e\u003c\/p\u003e  \u003cp\u003e\u003cb\u003eInput Section\u003c\/b\u003e\u003cbr\u003eInput signals may be derived from   mic or line sources (make sure 48V is off for line sources!). The input   has a 10K ? non-reactive input resistance that handles a full 22dBu   signal without the need for a pad. The preamp is a TLA non-reactive   design that precludes the loading of microphones with limited driving   capability. A primary gain control provides 66dB of gain in 6dB   increments for easy recall, with a +\/- 6dB trim for fine adjustment. For   condenser microphones and powered DIs, there is +48V phantom power. A   transient-optimized HPF continuously covering the range from 20-250Hz is   included to tame rumble and proximity effect.\u003c\/p\u003e  \u003cp\u003e\u003cb\u003eTexture\u003c\/b\u003e\u003cbr\u003eOne of the key developments in the 511 is   the Red Silk \/ Texture control from the Portico II Channel. Building on   the “Silk” mode found in the Portico Series mic preamplifiers, Texture   is designed to adjust the actual amount of harmonic music content from   the source material, in effect, providing wide range of tonal options   for the preamplifier. Like the original Portico Silk, the Silk Red \/   Texture works by reducing negative feedback on the output transformer   and adjusting the frequency response to more closely resemble Mr. Rupert   Neve’s vintage designs. With the 511, the Texture control allows these   techniques to be pushed further than previous designs, adding about 10   times the desirable THD of the original silk control at the maximum   setting.\u003cbr\u003e \u003cbr\u003e With that said, we have taken great care to ensure   that the musical integrity of source material itself will not be   compromised by these harmonic controls (these are not to be confused   with controls from other manufactures that may “incinerate,” “demolish”   or “destroy” source material), and we believe they can be confidently   modified to fit the personality of any song, instrument or engineer.\u003c\/p\u003e  \u003cp\u003e\u003cb\u003eLow Noise, Low Distortion Operation\u003c\/b\u003e\u003cbr\u003eMuch care was   given in designing the 511 to produce as little noise and non-harmonic   distortion as possible. Carefully implemented signal paths and Class A   operation are a large part of the 511?s sweet, whisper quiet   performance.\u003c\/p\u003e  \u003cp\u003e\u003cb\u003eWhy Transformers?\u003c\/b\u003e\u003cbr\u003eA complete discussion on   transformers is out of place at this point, but it is helpful to review   some of the essentials where it will be seen that a design needs to be   viewed as a whole, not simply from the point of view of a single   component.\u003cbr\u003e \u003cbr\u003e The fine subtleties of circuit design relating to   sonic performance are gradually becoming more clearly understood. For   example, research has shown conclusively that frequencies above 20 kHz   affect the way in which humans perceive sound quality. But, long before   scientific evidence emerged a substantial body of musicians and   engineers knew that equipment with apparently the same technical   measurements could sound very different.\u003cbr\u003e \u003cbr\u003e Incredibly small   amounts of musically dissonant odd harmonics have a disastrous effect on   the sound quality. Extraneous noise or interference that finds its way   into a signal path seriously impairs performance of the whole chain.\u003cbr\u003e \u003cbr\u003e   Many control rooms make use of outboard gear that is not well protected   from external signals. Poor grounding of such equipment can be a   serious problem. “Electronically balanced” circuits much used in modern   equipment, can give very good measurements on the test bench but they do   not provide adequate rejection of the stray fields found in every   working environment.\u003cbr\u003e \u003cbr\u003e Input and output circuits must be freed   from ground dependence so that only the “wanted” signal enters and   leaves the processing path. Transformers are the ideal solution. The   sweet and silky sound of my classic old favorite consoles was achieved   with big transistors and large high quality transformers. Rupert Neve   Designs Portico modules achieve similar quality today without the bulk   or the cost.\u003cbr\u003e \u003cbr\u003e In order that modules can work together as would   be expected (i.e. in a proprietary console configuration) without   producing hum, R.F. interference, or other interactions, the connecting   interfaces, grounding, levels and impedances must receive careful   attention. Each Portico module is a complete integral signal processor   that delivers its specified performance independently. This is one of   the reasons we use transformers.\u003c\/p\u003e","brand":"Rupert Neve Designs","offers":[{"title":"Default Title","offer_id":44450939928679,"sku":"186392","price":395.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/rupert-neve-designs-portico-511-511e0460-used_186392_1_320633c1-5d27-43e7-9a84-410c89f0bb8d.jpg?v=1787095186","url":"https:\/\/vintageking.mom\/products\/rupert-neve-designs-portico-511-511e0460-used","provider":"Vintage King","version":"1.0","type":"link"}
