Description

The vintage EQ tones you know & love.
The 551 is the only equalizer for the 500 Series actually designed by Rupert Neve. Featuring 3 bands of EQ inspired by Mr. Neve’s most prized vintage designs, along with custom-wound inductors, transformers and class-A gain blocks, the 551 brings the thick, powerful lows and sweet highs of Rupert’s classics to the 500-Series format.

The “Best-Of” EQ
The 551’s 3-band, custom-tapped inductor EQ was inspired by our favorite elements of Rupert’s vintage EQ designs. The low frequency band is designed to produce a creamy, resonant bass response similar to a vintage 1064 – but unlike the vintage modules, the LF band on the 551 can be used as either a shelf or a peak filter, adding punch, dimension, and control to your low end.

The midrange band is based on that of the 1073, ideal for sweetening vocals and instruments while bringing them forward in a mix, and its proportional “Q” response makes it well-suited for minimizing problematic frequencies. The high frequency band is a hybrid vintage / modern design, blending inductor circuitry with capacitor-based topologies to achieve vintage tones with enhanced control. The High Pass filter is a 12dB/octave design with a fixed 80Hz frequency, and can be used in tandem with the low frequency EQ to add low-end presence without clouding the source material.

As with Rupert’s most prized classic designs, each EQ section uses low-feedback, class-A discrete electronics to prevent low-level artifacts and harshness from detracting from the tonal shaping. However, this new circuit is a decidedly modern design with updated techniques and components that were simply not available 50 years ago, and is definitely not a “clone”.

What Are Inductors?
Inductors are wires wound around a coil that provide a form of frequency-dependant resistance. When they saturate, they bring out beautifully musical harmonics that give your tracks the smooth, polished sound that has made Rupert’s consoles and equipment so desirable for over fifty years. This is what makes them different from capacitor-based EQ designs, which do a great job at surgical equalization. But inductors provide the tone.

While it is certainly possible to create a functioning EQ using off-the-shelf inductors, we choose to use our own custom inductors for the 551. This attention to detail in controlling variables such as the winding and core materials in relation to the surrounding circuitry allows the 551 to capture the vitality and personality of Rupert’s classic designs.

Originally developed for the dynamics circuit of the acclaimed Shelford Channel, the 535 Diode Bridge Compressor captures the soul of Rupert Neve’s original 2254 compressor while providing modern updates including advanced timing control, significantly lower noise, fully stepped controls throughout, and internal parallel processing capabilities. What is diode bridge compression? Where the VCA compressor found in the Master Buss Processor provides unmatched clarity, the weighty, harmonically rich tonality of diode bridge compression can be essential in pushing key sources like vocals, electric guitars, bass and drums to the forefront of a mix. By understanding the limitations of vintage units like the legendary 2254, painstaking effort was taken to reproduce the unique tone of these classics while improving the noise floor & accuracy, expanding inflexible time constants, adding full wave sidechain detection for improved dynamic response, and widening the range of threshold and ratio controls. Delivering the powerful sound of these iconic designs with enhanced flexibility for the modern age, the 535 Diode Bridge Compressor is a dynamic tool equipped to make a bold statement on virtually any mix or track.

The product that started it all for Empirical Labs. Born of founder Dave Derr’s love of classic compressors like the 1176, LA-2A and Gain Brain (among others), the Distressor incorporates his favorite sonic characteristics of these, along with other unique and interesting features that have made it a staple for audio engineers all over the world. With over 28,000 units in the field, it’s safe to say that the Distressor is one of the best selling high end compressors of all time… if not THE best selling. A prominent recording engineer recently wagered that there probably was not a top 40 record made in the last five years that didn’t have at least one Distressor on it.
Besides providing a wide range of control and a unique feature set, the Distressor offers a warm, vintage sound by using a custom designed gain control circuit. This “warmth” or “vintage sound” has become a major issue in the last few decades, as the super clear and linear digital technology does next to nothing to soften “harsh” sounds, nor emphasize the bass frequencies in music sources. Conversely, older analog tape, vinyl records and tube equipment could not be prevented from coloring the sound, often to the frustration of recording engineers. However, many people now realize that this coloring can be extremely pleasant and musical. Digital technology is often referred to as “cold” and “brittle” among other terms (although we prefer “unforgiving”).
Unique Compression Curves All eight of the Distressor’s curves are unique and distinctive, from the 1:1 mode that simply warms up signal with low order harmonics without intentional compression, to the “Nuke” setting – a brick wall limiting curve that shines on live drum room mics. Each curve has its own personality and several actually use different circuitry, and are effectively different compressors. Most exceptional is the 10:1 “Opto” ratio which uses separate detector circuitry to emulate the oldest (and valued) “light controlled” devices, such as the LA-2A.
Distortion (Color) Modes Another large part of the Distressor’s personality and power derive from three modes that color the signal, even without compression. These extended audio modes were designed to allow emulation of some very old and expensive vintage compressors & limiters, and let the Distressor deliver a classic “knee” sound all its own by providing user programmable, warm harmonic distortion. In addition to the basic distortion mode, Distort 2 emphasizes tube-like 2nd order harmonics, while in Distort 3 setting the distortion becomes dominated by 3rd harmonics more closely resembling tape. Two HP filters – one in the audio path, one in the detector path – are also available to help with low frequencies that can cause pumping and breathing.
British Mode The concept of British Mode came from an unusual setting on the classic UREI LN1176 limiter. The unit was designed to have only four ratios, each ratio being engaged by selecting one of four buttons. However, as early as 1980 (or before), renegade recording engineers, always on the lookout for something a little more “over-the-top”, found that you could make all four buttons stay in if you pressed them just right. What resulted was a very aggressive sound that had some elements of the unit’s 20:1 ratio, but with an unusual knee and new envelope shape. Somewhere along the line, someone called it “British Mode”, and the name stuck.
The EL8-X has the advantage of being able to selectively apply this aggressive characteristic – not just to the new “British” ratio (1:1) – to any of the ratios, simply by engaging the dedicated “British Mode” switch.
The British Mode and Image Link options are only available on the EL8-X.
Image Link The original Distressor stereo link function used a summing and phase detection method, which allowed slight stereo image shifting. Although frequently desirable for its phase correction, and its “thickening” on open room mics and other stereo sources, this approach can sometimes be a problem on stereo program material where the producer/engineers want to maintain absolute left/right balance at all times. With the new “Stereo Image Link” option, the EL8-X now has three link options – the original “phase” link, the new Image Link and the combination of the two, phase and image linking – something never before offered on any compressors or limiters.

In today’s modern age of digital recorders, DAWs and software plug-ins, Mike-E is the ultimate solution for getting a clean and strong, yet warm and musical signal into the box…and it couldn’t be easier to work – its front panel layout is so straight ahead that even inexperienced engineers will have no problem moving around on it right away. When the engineering team at Empirical Labs sets out to build a microphone preamp, you can be sure it’ll deliver spectacular sound, be effortless to work, and will provide features unlike any other device in its class. To that end, we proudly present Mike-E, a high performance transformer-coupled mic preamp with a noise floor far below any microphone’s self noise, combined with a one-of-a-kind compressor/saturator circuit that delivers classic knee compression as well as versatile tonal ‘coloring’ that can replicate many of the best characteristics of vintage analog recording equipment. Mic Preamp The Mike-E features a super low noise transformer input amplifier section with the gain under precise digital control. The signal to noise far exceeds any microphone in existence. Having used many mic preamps over the years, we’ve implemented a unique stepped gain control that should be impervious to the normal flakiness that age causes to pots and detented switches. A “Bad!” LED indicates when the input signal is overloading the circuit. CompSat The CompSat’s unique circuitry sets the Mike-E apart from all other mic preamps.
  • SATURATOR –  a multi stage soft-clipping circuit. At lower levels, a triode-type saturation affects the signal. As the level increases, a second unique clip circuit starts to more severely flatten out the peaks.
  • COMPRESSOR – based on ELI’s world famous Distressor, but with other characteristics (including a much longer attack time).  Preset ratios include: 2:1, 4:1, 8:1…and, of course, Nuke.
  • EMPHASIS – a two-stage circuit that boosts and soft clips high frequencies before the CompSat™ circuit, and then cuts the frequencies after it. Emphasis has the added perk of improving signal to noise, and is the reason analog tape decks used emphasis to begin with.
Frequency Response: 3 Hz to 200 kHz on (No CompSat). CompSat is 3Hz – 150Khz. Optional Transformer output is 6Hz–80kHz. Signal to Noise: 130 dB signal to Noise.at 40dB gain. Maximum output is +28dBu.
