Langevin Langevin Pultec EQ.

The Langevin All-Discrete Pultec EQP-1A is the solid-state version of Manley's Enhanced Pultec EQP-1A (#620887), their interpretation of the historic Pultec Equalizer as originally produced by Pulse Techniques, Inc. Manley has been building these Manley Pultec EQs since 1990, after hunting down the original Pultec designer, Eugene Shenk, in deepest darkest New Jersey, to ask for his permission and blessings to produce the Manley own version of his classic piece. The Langevin Pultec units employ Manley's own simple and clean solid-state all-discrete make-up gain block to reamplify the signal after the passive EQ circuit.EQ may be set to flat positions or bypassed entirely. All Boost and Cut controls are continuously variable conductive plastic potentiometers for absolutely silent operation and long life. Manley single-rack-unit monoblocks occupy one-third of the space of the "antique Pultecs," an important consideration for allocation of outboard rack space. And, you'll notice, that Manley added a couple extra frequencies too. The rear-mounted input switch selects 0 degrees or 180 degrees Phase Invert for the balanced gold-pin XLR input or the transformerless unbalanced bridging input (1/4" jack) may be selected in that switch's middle position.People often ask us if Manley Pultec EQ's sound like the old ones to which we reply, "Yes! But better!" The originals had three transformers in the signal path whereas this Langevin Pultec is completely transformerless. Manley's all-discrete line amp is really clean and natural sounding. The components Manley uses today just weren't available in the 1960's. So, if you want a project with crackling carbon pots, dirty open frame wafer switches, 5% and 10% tolerance noisy carbon resistors, exposed tubes sticking out the back of the 3U chassis, etc., go pay top dollar for an antique Pultec!Kick drum? Bring on the Pultecs! You'll soon discover the power and magic of having those individual Low Frequency Boost and Cut controls in that LF shelf circuit... Need a little clarity or extension? Try that middle bell-shaped Boost dialing in the sharpness of the boost on the Bandwidth control. Something bugging you? Ease it off with the HF shelf control. You'll see: There's no substitute for a Pultec! The Langevin unit works the same way as the Manley unit but has an ALL-DISCRETE make-up gain amplifier instead, with both balanced and unbalanced inputs and outputs — all completely transformerless. It is known to have an incredibly sweet top end.. ...details

Langevin Langevin Mini Massive Stereo EQ.

The Langevin Mini Massive is the little brother to Manley's Massive Passive EQ. This rackmount EQ is based on the same passive EQ sections as the Massive Passive's Low Band and High Band and shares most of the same components and circuit layout. The Mini Massive is smaller at only 1U high and about half the price and includes some improved features, refinements and excellent clarity so it's fit for mastering at its best.Manley revisited the 4 lowest shelf settings, and the 4 highest frequency shelf settings, plus added higher Q bell shapes for the 4 highest frequencies. This gives even more opportunities for Pultec-like fatness and beyond in the deep lows. The high frequency curves are designed for air, sweetness and sparkle. Compared to the Massive Passive, the toggle switch on the Langevin EQ that selects between Bell and Shelf, has become a 3 position switch, to introduce the new higher Q Bell curves on the 4 highest frequencies. These features give the Mini Massive even more power and flexibility to achieve that elusive big round tight bottom and silky atmospheric top.The Langevin Mini Massive EQ uses 4 Manley Rapture® Amplifiers for gain. These came about in the long search for the cleanest and most musically involving gain stage we could get and were originally intended for a cost-no-object digital / analog converter. These are further augmented by both series and shunt power supply regulators, to provide a refined low noise power supply. Like the Massive Passive, huge headroom is available and the Mini will output +30 dBv balanced into 50 ohms. And rather than using unstable cross-coupled outputs to drive balanced or unbalanced loads, the Langevin Mini Massive can accommodate balanced, or unbalanced +4, or unbalanced –10 loads, and each one is always driven optimally. It plays well with others.For those who would prefer the sound and ease of interface that transformer-coupled outputs provide, we have made the same transformers as used in the Manley Massive Passive a stock item here in the Langevin Mini Massive EQ. These can add a subtle degree of warmth and smoothness when used in the signal path. A 3-way toggle IRON switch on the back panel switches the transformers into the circuit or bypasses them or forces them into a more vintage-like flavor for even more fat and aggressive colors.Of course, for those who want a Mono 4-band EQ only need to patch the output of Channel 1 into the input of Channel 2. The low band ends at 1K and the high band begins at 560. Shelf frequencies still go that far and still offer dramatic curves.The Mini Massive is the EQ for those who consider the Massive Passive too big, too expensive, or too colored or maybe not the first choice for extreme lows or extreme highs. The Massive Passive was designed to be a tube EQ with character and with the creative potential of forgotten passive techniques. The Langevin Mini Massive Stereo EQ is a clean, lean machine, with the same EQ performance, and t. ...details

Langevin Langevin Stereo ELOP Limiter.

Set it and forget it! The Langevin Stereo-Optical ELOP Limiter makes your job easy. The principle of operation is based around using a rectified sample of the audio to shine an LED (Light Emitting Diode) onto an LDR (Light Dependent Resistor). The photo-resistor in combination with a fixed resistor simply act as a changing voltage divider to attenuate the signal &mdash like a smart volume control. A similar principle was found in the older Teletronix & Urei LA-2A, LA-3, and LA-4 units, which used a slower electro-luminescent panel-light on a conventional LDR encased in a light-tight enclosure. Manley uses modern VACTROL technology (but with a trick!) for exact sample-to-sample tracking and no high-frequency loss while digging deep into limiting &mdash problems commonly associated with older LA-series limiters and other opto-based units. The Langevin limiter's audio signal passes only through Manley's super-clean single-ended vacuum tube line amplifier. Each channel can be run separately or switched to "stereo &mdash link ". Due to its inherently quick attack, this Electro-Optical Limiter is a skilled soldier for tracking vocals or individual instruments, although now with the addition of a very useful sidechain high-pass filter that can switch between 100Hz or 200Hz (or OUT) to allow the limiter to ignore heavy bass lines, the ELOP limiter is proving more useful for modern urban music where you don't want the limiter only responding to the loudest "thing" i.e., the BIG bass. If you want the bass line to leave the rest of the mix alone, then this switch is for you!. ...details

Langevin Langevin Dual Mono Micpre w/EQ.

This dual-channel microphone preamplifier is Langevin's refined version of the historic Langevin AM-4 console channel. Langevin has developed their own discrete gain stage to provide for balanced outputs — to bring the Langevin brand into the modern age, while still retaining that desirable tone that discrete circuitry delivers. There are no IC's in this mic preamp unit. Langevin also added 1/4" DIRECT INPUTS addressable from the rear panel. The continuously variable plus and minus 10dB shelf EQs switched turnover points have been chosen carefully at 40 or 80Hz (L.F.) and 8 or 12KHz (H.F.). All EQ can be completely switched out or set to 'flat' positions. Up to 53dB of gain is available to accommodate a wide range of microphones and high-current 48 volt phantom powering is built in. Because the most single influential component in a mic pre has to be the input transformer, the mic preamp features the precision MANLEY mic input transformers, for that natural sound with a touch of brawn good iron provides.. ...details

Langevin HP-101 8-Channel Headphone Mixer.

Langevin calls this unit the "More Me" Box because it's possibly the headphone mixer's most important feature. Along with the typical cue mix or the control room mix, the engineer can offer each musician a separate fader dedicated to his or her own instrument. Experience teaches us that each musician always wants to hear more of themselves and that trying to meet this demand with several musicians and with too few aux sends is a mind-bending challenge. As long as each musician's headphone is plugged into a separate station, each musician can have their own custom mix within arms reach. This frees up the engineer to concentrate on recording and getting the best sound. It allows the producer to focus on performances because the musicians' monitoring needs are met quickly and easily. It also frees up console aux sends so that they may be used for effect sends. With the Langevin HP-101 mixing station, you will be able to offer musicians a better sounding headphone amp than most major studios and be able to provide some significant improvements over basic stereo cue boxes or any other headphone system we know of.The Langevin HP-101 Studio Headphone System provides 8 x balanced inputs: four mono channels with FADER and PAN plus two stereo feeds with rotary switches providing stereo, mono and SIM processing. This cool SIM setting monos the bass, which makes it sound more like listening to real speakers. Channel one on the Langevin mixer has a PHASE switch, intended primarily for the vocalist. Voice is heard through the bones in the head as well as the phones. You may not hear much difference switching the phase in the control room but the person at the mic certainly will. Polarity gets inverted all the time in studios, which may explain why sometimes the vocal is so loud in the phones or sounds different on playback to the singer. Our PHASE switch sure does come in handy.The 8 inputs on the Langevin headphone mixer appear on ELCO multi-connectors, wired to ADAT standard, making linking or daisy-chaining several stations easy. Langevin approaches cable making as a custom order which means prices depend on length and quantity and connector choice.. ...details

Langevin Langevin HP-112 12-Channel Headphone Mixer.

The Langevin HP-112 12-Channel Headphone Mixer has many of the same features as the HP-101 8-channel model except there are 4 more mono inputs. Yes, the HP-101 8-channel units and the HP-112 12-channel units can be mixed in the same installation as far as the ELCO cabling is concerned however, the 8-channel headphone mixers won't receive signal channels 9-12 from the 12 channel units. (Duh.) All the rest of the functions (talkback, logic, Interrupt, Mic etc.) are 100% compatible between both models. See HP-112 ELCO pinout here.The Langevin Headphone Mixer's Mute controls the Power Amps directly and steps through ON, MUTE, LEFT MUTE and RIGHT MUTE then back to ON. Each station also has bass and treble EQ controls carefully optimized for headphones. The master stereo volume control feeds the built-in power amps which produce peak voltage (equivalent to) well over a hundred watts per channel to drive up to 4 headsets at any volume the musician may choose. No weeny little beetles like you'd find in your Walkman here!The two features that impress the musicians the most are the easy communication with one button and the fabulous sonic quality even at extreme levels. Ever clever, the ELCO connectors also provide pins used for several other communication and monitoring functions, including TALK and INTERRUPT. There are also hidden features on the ELCO's such as the ability for the control room to monitor each station's headphone mix or to hear the unswitched "always-on" individual station microphone.. ...details

Langevin Dual Vocal Combo.

The Langevin Dual Vocal Combo is a 2-channel microphone preamplifier with 2 shelf equalizers plus 2 channels of electro-optical limiters. The combo is the result of suggestions from Langevin customers to combine two of the most popular Langevin signal processors and make the price irresistible, half the price of the VOXBOX combo in fact, for 2 channels of great sounding all discrete channel strips. Seem interesting? This includes VU meters, individual phantom power, limiter linking and time proven circuitry. This is an ideal box for musicians and engineers on a budget and is equally at home in a big league recording studio, mobile recording truck, or live gig. The Langevin DVC has the reliability, functionality, and the sound without any of the complexity— the essential features without the "sea of knobs." The Mic Preamps are transformer coupled (hand wound by Manley Labs) with 50 dB of gain provided by pure discrete transistor circuits, same as found in the stand-alone Langevin Dual Micpre. 48-volt phantom power can be applied to each input XLR independently and the switches are a locking type to prevent accidents. New to this unit are the front panel 1/4" Direct Instrument inputs. A little discrete circuit from our tech Paul Fargo gives these inputs the appropriate input impedance (150Kohms) and provides about 40 dB of gain. The Equalizers are comprised of a low frequency shelf that can be switched to either 40 Hz or 80 Hz and a high frequency shelf that can be set for 8 KHz or 12 KHz. Very tasty choices! These shelves are continuously variable from -10 dB to +10 dB of gain. Of course, the Langevin EQ can be completely switched out with the BYPASS switch making it easy to make a choice. The Limiters are the discrete transistor version of the Manley ELOP Limiter (same as the Langevin stand-alone version). This type of limiter is superb for vocals and a wide range of instruments from basses and guitars to synths and room mics. When it comes to tracking and fast set-ups, the lack of a multitude of controls is a real feature. You can simply set up the Threshold and Gain controls and expect that the limiter will do the right thing without a lot of tweaking. The Langevin Limiters have Threshold and (make-up) Gain controls, a Link switch for stereo and a pair of toggles that switch the VU meters to "Gain Reduction" or "Output Level". These are true stereo limiters without the usual problems of left/right matching common to other stereo opto based limiters. The back panel has XLR mic inputs paralleled with 1/4" TRS jacks that feed the mic pre stage. By popular request Langevin has added separate 1/4" TRS micpre outputs which "normal" into the 1/4" TRS limiter inputs so they can be permanently wired into a patchbay. Now there are "Direct Outputs" from the Mic Preamp/EQ stage so one can indeed use the mic preamps and the Limiters as 4 separate sections. The main outputs are avail. ...details
