For 50 years the 1176 has been a vital tool in music production revered for it’s fast compression/release and warm tone that only FET circuitry can offer. "[4], Jim Scott says "They have an equalizer kind of effect, adding a coloration that's bright and clear. The original Universal Audio 1176 limiting amplifier designed by Bill Putnam was a major breakthrough in limiter technology.It was the first true peak limiter with all transistor circuitry, offering superior performance and a signature sound. Another minor revision in the early 70s was the addition of a power transformer to switch between 110v and 220v. Resistor values were changed in the signal pre-amp stages, and bypass capacitors were added around the resistor feeding the gain reduction FET. $2,200.00. I like how variable the attack and release is; there's a sound on the attack and release which I don't think you can get with any other compressor. The initial units (A and AB revisions) were available in 1967 and were informally referred as "blue stripe" for their blue-colored meter section. Improvements continued to be made over the years, with the result that there are 9 major revisions of the vintage 1176, given the letters A, A/B, B, C, D, E, F, G, H . This new 1176 LN stays true to the original designs of Bill Putnam and introduces the compressor to a whole new generation of users. Program dependency behavior was removed. In 1966, Bill Putnam, engineer and founder of Universal Audio, began to employ the recently invented field-effect transistors (FET), replacing vacuum tubes in his equipment designs. From the beginning the 1176 had … Covering up all this electronic wizardry was a brushed aluminum faceplate with blue paint around the Weston meter. This became known as "All-button" mode or British mode,[4] and is popular enough to be explicitly supported by modern clones of the 1176. The op-amp input Blackface G and Silver-face H In the world of analog hardware, the Purple MC77 and Retro Instruments 176 are among some of the most widely used in the world of the studio. or Best Offer. The low-noise Blackfaces C, D, and E [2] At the time of its introduction, it was the first true peak limiter with all solid-state circuitry. However, British engineers discovered it was possible to push all four buttons in at once, an unexpected use case that led to unintended behaviour, with a substantial increase of harmonic distortion. Revisions F/G 1973: Pulling out of class A / Integrating integrated circuits. The final major change to the circuitry occurred in Revision G. The input transformer was removed and replaced with a differential input op amp stage. MSRP is $2,295. Though the audio circuitry remains the same as the reissue 1176LN from the same period, rotary switches replace push buttons for ratio and meter selection, and metering options are limited and the meters are notably smaller. The OG: Universal Audio 1176LN (reissue) The fact that it’s made by Universal Audio (which was reestablished by Bill Putnam’s sons in 1999) means that the reissued 1176LN is the only one that can lay claim to being ‘the original’. As its predecessor, the 1176 utilizes soft knee compression[4] and fixed threshold: compression amount is controlled through the input control. Based on the look of their faceplates, Revisions A, A/B, and B are all nicknamed the "Bluestripe," since they all featured a section of blue paint around the VU meter. Purple Audio MC77 or Universal Audio 1176? Also, a Q-bias pot was added to the feedback circuit of the audio FET, to minimize distortion. Also, a tap off the emitter of the first transistor gave feedback of the input voltage back to the gain reduction FET. The rest of the design features two black plastic control knobs with silver tops and clear plastic collars, two smaller black and silver knobs, eight black plastic pushbuttons and a red power indicator light. Description. Universal Audio was a designer and manufacturer of recording, mixing and audio signal processing hardware for the professional recording studio, live sound and broadcasting fields. This strange phenomenon might be described as a "reverse look-ahead". The most powerful compressor of them all. Apollo x8p; Apollo x16. For those working in the box, look no further than the Waves CLA-76 and Universal Audio's Classic Limiter Collection, both of which expertly recreate the compressor in digital form. Please. Available Vintage & Used 1176 Compressors, Universal Audio 1176 LN Classic Limiting Amplifier, Retro Instruments 176 Tube Limiting Amplifier. The Universal Audio 1176LN Limiting Amplifier was an instant classic. The ratio buttons are designed to be mutually exclusive, so that pressing one ratio button deselects the others. By about #2300, the switch was moved to the right of the fuse, with the power cord being moved directly underneath the fuse. This was a major facelift for the model that would become the basis of all future 1176 versions. Fill out this form to get on the waiting list and we will notify you as soon as one is available. Sorry, no products are currently available. It features ultra-fast attack and release times and a broad palette of sonic malleability ranging from inconspicuous compression to flamboyant distortion. instructions for the Universal Audio 2-1176 Limiting Amplifier. I have a Universal Audio 1176 that is a few years old. Still built today by Universal Audio, the 1176 Peak Limiter is one of the most sought after compressors in the world. This Universal Audio Classic version of the 1176LN captures all the nuance of the original through obsessive attention to detail and delivers that trademark sound. Production were resumed with T-pad attenuators and 012 Magnetika input transformers. Audio Interfaces. The output transformer was changed to the B11148 type (already used in UREI LA-3A). The faceplate was changed from black anodized to natural brushed aluminum. The FETs were replaced by a 2N3391A bipolar transistor. The Universal Audio 1176 Compressor/Limiter was first introduced in 1968, created by Bill Putnam Sr. as the solid state successor to his tube-based 176 limiting amplifier. This circuit was sealed in epoxy to keep it secret while a patent was pending. Note that some revision B units appear to have been later upgraded by Urei to the Low Noise spec, as indicated by the lower serial number with a replacement black faceplate. This revision had no circuit changes, but the additional low-noise circuitry was incorporated into a new main circuit board. $95.00 shipping. Occasionally, the letter "B" appears after the serial number. I just bought a UA 2-1176 and it sounds no where near as good as my 1176. Billed as a “true peak limiter with all transistor circuitry,” the 1176 quickly became a favorite among audio engineers for its ability to limit transients with lightning speed. The information contained in this manual is subject to change without notice. These have the classic character and lower noise floor that is the heart of the 1176 sound. The Universal Audio silkscreened logo was removed and replaced with a blue Urei logo on a raised badge, (sometimes only a black printed Urei logo is used). I would think the circuits are somewhat similar, if not exactly the same. Modern versions hearken back to this era. The original 1968 design by Bill Putnam used an input transformer at the industry standard 600 ohms resistance (Peerless, later UTC), a T-pad resistive attenuator to drop the input voltage, a FET acting as a voltage variable resistor to control gain, followed by a bipolar transistor as a preamp (the famous 1108 circuit with a Darlington pair). Universal Audio's current reproductions are based on these revisions, so if you are looking to DIY an 1176 rather than buying a new one, rev D is the way to go. One-third of all vintage 1176 units are of this type. Universal Audio 1176 (#2) Reservation Calendar / / Add to Cart. Here’s how Universal Audio describes this unique setting: Billed as a “true peak limiter with all transistor circuitry and superior performance on all types of program material," the 1176’s major selling … Apollo x16; More; UAD Accelerators. Get the best deals for universal audio 1176 at eBay.com. The original Universal Audio 1176 was designed by UA founder M.T. This version continued the classic sound, but changed the output transformer for considerably higher gain. [6], Revisions D and E are reputed to sound the best. © 1993 - 2021 Vintage King Audio All Rights Reserved. But in all-button mode, a few more things are happening; the ratio goes to somewhere between 12:1 and 20:1, and the bias points change all over the circuit. As a result, the attack and release times change. The 1176 underwent a number of revisions; one notable change in the early revisions was the addition of Brad Plunkett's circuitry, which reduced noise by 6 dB and redistributed the noise spectrum, producing even more noise reduction in the sensitive mid-range; linearity was also increased by reducing harmonic distortion. The next year saw some more changes to the preamplifier circuit. By By Michael Cooper Published: 11/01/2004 The 2-1176 Dual Limiting Amplifier is a 2-channel version of Universal Audio’s ’60s-era 1176 and uses the same FETs (for gain control elements) and output transformers. Urei 1176 Rev F - Michael Brauer Rack LN Peak Limiter - Universal Audio. The new unit employs metal-film resistors, which produce a lower noise floor than the carbon-film resistors used in the vintage 1176. It was renamed to 1176LN and the face color changed to the now familiar solid black. With its distinctive tone and its wide range of sounds, deriving from the Class A amplifiers, its input and output transformers, the uncommonly fast attack and release times and their program dependence, and different compression ratios and modes, the 1176 was immediately appreciated by engineers and producers and established as a studio standard through the years. The 1176 was originally designed by Bill Putnam Sr. in 1968 as a solid-state alternative to his successful 176 tube compressor. It's very colored in sound and doesn't have the high bandwidth sound of the newer compressors but who cares. Origin Effects has managed to squeeze studio hardware components into a stompbox size pedal to offer a classic vintage-sounding compressor. The new Universal Audio 1176LN reissue is based on the D and E revisions and comes as close as you can get to "the sound of '67" without a time machine. Both of these mods were mounted onto an otherwise normal Revision B circuit board. _____ Stereo Operation and Calibration With the use of an external 1176 Stereo Adapter (1176SA), available from Universal Audio, two 1176LNs can be connected for stereo operation. When it comes to modern versions of the 1176, the first place to start is with the Universal Audio 1176 LN. I usually use them on four to one, with quite a lot of gain reduction. Reproduction based on C, D and E revisions; most resembling the E model, due to the use of the switchable power transformer. Apollo x8; Apollo x8p. Overview The 2-1176 was briefly issued in the early 2000s, and is a stereo version of the 1176LN in a 2U enclosure. The Purple Audio does sound better than the RI's IMO but the RI's are still a massive piece of gear. The big thing for me is the clarity, and the improvement in the top end. Is there a likely culprit for this difference?? USING THE 1176. However, the company was re-established as Universal Audio in 1999 by the sons Bill Putnam, Jr. and Jim Putnam, and re-issued the 1176LN as its first product. The modern reissue of the 1176 is based primarily on these versions. The shape of the compression curve changes dramatically in all-button. Universal Audio was responsible for many innovations in the recording and sound reinforcement industry including the modern mixing console layout, per channel equalization (or EQ) and effects connectors (or send buses). To what degree is once again material dependent. I really hope you get a chance to spend a few days with any of the mentioned hardware versions or at least enough time to learn what they are about. Apollo Solo. The 1176 was meant to be a "true peak limiter" with a very fast attack of up to 20 microseconds, and lots of gain for a compressor: up to 45 dB! Developing the 1176LN —as well as Universal Audio’s entire line of quality audio products designed to meet the needs of the modern recording studio while retaining the character of classic vintage equipment—has been a very special experience for me and for all who have been involved. These changes improved noise and stability. $15,999.00. The output matching transformer at 600 ohms was a UA-5002 (later improved to UA5002A) with a split secondary, a tertiary winding for negative feedback to the final line output circuit, and a separate emitter winding. The meter drive circuit was also changed, replacing the discrete circuit of balanced bridge transistors with an operational amplifier, to simplify meter calibration. The 1176 will faithfully compress or limit at the selected ratio for transients, but the ratio will always increase a bit after the transient. It uses a FET (field effect transistor) wired in a feedback configuration to reduce gain. Universal Audio Part Number 65-0010 Revision 1.0 Universal Audio, Inc. The 1176LN was inducted into the TECnology Hall of Fame in 2008.[3]. But, they sound so different from each other. The way the 1176 sounds, and specifically, the way all-button mode sounds, is partially due to its being a program dependent compressor. For assistance in better understanding the content of this page or any other page within this website, please call 888.653.1184 during normal business hours. [1], Mike Shipley says "The 1176 absolutely adds a bright character to a sound, and you can set the attack so it's got a nice bite to it. The originals were somewhat noisy, prompting Brad Plunkett of Urei to design the Low Noise circuit that gave the unit its "LN" designation. UAD-2 Satellite; UAD-2 Satellite USB. All cosmetics remained the same. The substance of these revisions is detailed below, gleaned from notes by Barry Rudolph, the Universal Audio website, and research on units sold by Vintage King. Revisions C through G all have the nickname "Blackface" for their black anodized aluminum, while the final Revision H is known as the "Silverface", for its natural brushed aluminum. [1], Bill Putnam sold UREI in 1985 and Revision H was the last series produced by the original company. Many units still bore the old serial number stickers with the former street address, as the chassis built in Hollywood were still being used until the move was finally complete. Notice This manual provides general information, preparation for use, installation and operating instructions In conjunction with this, the UA5002A output transformer was replaced by the B11148 transformer (used in the LA-3A), providing 12 dB of gain. Uh… we’re glad they went back to the original name.) $84.30 shipping. Thus, revisions C, D, and E are all virtually identical. The release time is program-dependent: it is quicker after transients to obtain a more consistent level, but it slows down after sustained and heavy compression to reduce pumping effects. This is the workhorse of the industry. When I go into a studio to mix a record without my racks, I make sure there are 4 of these in the room.” Apollo x6; Apollo x8. Revision C, designed in 1970, saw one of the major design evolution, with less noise and harmonic distortion. I listen for how it affects the vocal, and depending on the song I set the attack or release—faster attack if I want a bit more bite. No changes were made to the circuitry, and another couple thousand units were manufactured before the brand folded. Universal Audio 1176 (#1) Reservation Calendar / / Add to Cart. There are more of this revision (and less of rev D) than was previously thought. A few short months after the initial version, an intermediate step was taken to make some small improvements to the circuit and components. The Universal Audio 1176LN Classic Limiting Amplifier is a modern reproduction, yet every effort was made to remain faithful to UA founder Bill Putnam Sr.’s visionary design and intentions. The design of the unit went through numerous changes, taking a while to hit its stride. (At the time, UA was operating under the name UREI, or United Recording Electronics Industries.

SCOTTS VALLEY, CA • April 4, 2012 — Universal Audio (UA), a leader in professional audio recording hardware and software, is proud to release the 1176 Classic Limiter Collection for the UAD-2 Powered Plug-Ins platform and new Apollo High-Resolution Audio Interface. Several resistor values changes in signal pre-amp stages improved stability and noise. [1], The 1176 uses a field-effect transistor (FET) to obtain gain reduction arranged in a feedback configuration. UAD-2 Satellite USB; UAD-2 Satellite FireWire. After successfully adapting the 108 tube microphone preamplifier into the new FET-based 1108, he redesigned the 175 and 176 variable-mu tube compressors into the new 1176 compressor. Vintage King's Nashville showroom is available for curbside pickups. The only version with a blue "UREI" logo and without "Universal Audio" branding. Universal Audio’s 1176LN Classic Limiting Amplifier is a handbuilt, faithful reproduction of Bill Putnam Sr.’s original visionary design — an iconic piece of audio history that had a hand behind classic recordings from Led Zeppelin, The Rolling Stones, Michael Jackson, and more. The company says that the modern 1176LN is hand-built to Bill Putnam’s exact specifications. 1176 LN Urei Compressor CLONE by Classic Audio - A piece of Audio History. If you're a guitarist looking to add a high-quality compressor to your pedalboard, the answer to your search is the Origin Effects Cali-76 Compact. The 1176 Peak Limiter is a dynamic range compressor designed by Bill Putnam and introduced by UREI in 1967. Michael Brauer. “What's not to like? $75.00 shipping. USING THE 1176 The newly reissued 1176 operates in exactly the same way as a good, working vintage 1176. At approximately serial number 10750, Harman Electronics took over Urei, and the familiar black and silver Urei sticker on the rear was changed to a Harman sticker. The original design was reproduced and revised thanks to the extensive design notes left by Bill Putnam. This is what gives way to the trademark overdriven tone. After relaunching the brand in 2000, the design team at Universal Audio took cues from the Blackface 1176 LN, including the C, D and E revisions of the famous compressor. The final refinement was to eliminate the input transformer in favor of an op-amp, giving a cleaner sound. In 1970, two major and two minor changes were implemented. All the revisions to follow would maintain the same controls, but the red power light would disappear when the black faceplate was introduced. $6,995.00. You can use it on any instrument and it'll do the job of making the drums sound punchy, the vocal sound stressed, urgent and contained if you choose, the bass pop, the drum room explodes, the guitars drive, the piano harmonics shimmer. This is true for any of the 1176's ratio settings, and is part of the 1176's sound. In 1966, Bill Putnam, engineer and founder of Universal Audio, began to employ the recently invented field-effect transistors (FET), replacing vacuum tubes in his equipment designs. The next revision did not change the circuitry, but the new LN circuit and Q-bias pot of the previous revision were now integrated into a new circuit board instead of being soldered on as an afterthought. The Universal Audio 1176LN Classic Limiting Amplifier is a modern reproduction, yet every effort was made to remain faithful to UA founder Bill Putnam Sr.'s visionary design and intentions. Speaking of which, the 1176’s most idiosyncratic feature was made famous by studio types who did away with the manual. Revisions C, D and E (the first three with the LN circuit) are all very similar, and are generally the most revered. Universal Audio, Inc. makes no warranties of any kind with regard to this manual, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose. The new Universal Audio 1176LN reissue is based on the D and E revisions and comes as close as you can get to “the sound of ’67” without a time machine. The VU meter was changed to a Modutec "light box" type, using two internal lights, and the Off button for the meter was changed from black to red plastic. "[4], "UA's Classic 1176 Compressor — A History", "Model 1176LN – Solid-State Limiting Amplifier", "1176 and LA-2A Hardware Revision History", https://en.wikipedia.org/w/index.php?title=1176_Peak_Limiter&oldid=997850619, All Wikipedia articles written in American English, Creative Commons Attribution-ShareAlike License, The original design by Bill Putnam; it had a brushed aluminium.

The blue stripe disappeared and the UREI logo was placed over the meter, which was changed from a Weston to a Modutec with two overhead bulbs. This option is a marriage between Waves and one of the most popular mixing engineers of all time – Chris Lord Alge. The newly reissued 1176 operates in exactly the same way as a good, working vintage 1176. In 2000, the sons of Bill Putnam Sr. resurrected Universal Audio to make authentic reissues of the legendary gear from Urei. Apollo Solo; Apollo Twin MkII. The ‘all buttons in’ mode was popularised by British engineers in the ’70s. All cosmetics remained the same. Low Noise circuitry was added to the preamp stage in order to reduce the drain-to-source voltage of the gain reduction FET, keeping it within its linear range. It featured ultra-fast attack and release times and a broad palette of sonic malleability ranging from inconspicuous compression to flamboyant distortion. Comparing Universal Audio Plug-Ins To Their Hardware Counterparts, Vintage King's Inside Look At Universal Audio, Vintage King's Guide To Compressors And Using Them In The Studio. The 1176 uses a Field Effect Transistor, or FET, as a voltage divider to accomplish the task of compression, in conjunction with I/O transformers and a Class A line level amplifier. MSRP is $2,295. Their first release was the 1176LN, based primarily on revisions C, D and E of the most famous FET compressor in history. Around unit #6950, the Urei plant moved from North Hollywood to Sun Valley, California. Terms and Conditions | Privacy and Security | Accessibility. The FET feedback circuit was revised to minimize distortion. In 1973, some major changes were implemented. The attack and release are program dependent, as is the ratio. Furthermore, in all-button mode there is a lag time on the attack of initial transients. The compression character is handled by attack and release times and four selectable compression ratios. The Universal Audio 1176LN Limiting Amplifier was an instant classic. Aside from the Universal Audio reproduction, several other brands have worked to create their own versions of the 1176. FETs in the signal pre-amp were replaced with bipolar transistors (2N3391A). The 1176 is a 1976 classic from Universal Audio. The faceplate was changed to anodized black. Its Class A output stage, which incorporates a custom overwound transformer, always delivers sweetly musical results. The faceplate was changed to the original silver faceplate and included a red "Off" button. The push-pull, higher output Blackface F. This website uses cookies to ensure you get the best experience on our website. Originally designed and built during the 1960s, the 1176LN was the first to use a Field Effect Transistor (FET) as a voltage-controlled variable resistor, and that innovation was the key to the product's unique character. The input transformer was removed and replaced with a differential amplifier. On the rear panel were some key safety improvements: the fuse holder went from round to square and the voltage switch was moved to be above the new IEC cable input, replacing the attached power cord that had been a literal fixture of the device since the very first model. The output amp circuit was similar to the preamp, but followed by a 2N3053 bipolar transistor operating in Class A. These revisions, easily distinguishable for their solid black face panel, were labelled 1176LN. Metering circuit now uses an op-amp. Not only do they give you a little more impact from the compression, they also sort of clear things up; maybe a little bottom end gets squeezed out or maybe they are just sort of excitingly solid state or whatever they are. My preference is for the black face model, the 4000 series—I think the top end is especially clean. After successfully adapting the 108 tube microphone preamplifier into the new FET-based 1108, he redesigned the 175 and 176 variable-mu tube compressors into the new 1176 compressor. Low noise ("LN") circuitry was added in the signal preamp, reducing DS voltage on the gain reduction FET and keeping the FET within its linear range. It involves activated all the ratio switches at the same time. The final revision made no changes to the circuitry, only the cosmetics and the layout. The Universal Audio 1176 Compressor/Limiter was first introduced in 1968, created by Bill Putnam Sr. as the solid state successor to his tube-based 176 limiting amplifier. Derived from the 175 and 176 tube compressors, it marked the transition from vacuum tubes to solid-state technology.[1]. “Bill” Putnam, and represented a major breakthrough in limiter technology. An emulation of the legendary 1176LN compressor, a must-have dynamic processor for your VS recorder.
