"Everyonce inawhile a product comes alongwith ‘classic’ written all over it. And in acertain sense of the word, this product actually is a classic already." Mix Magazine
“Dear Empirical, I’m an LA based producer and an owner of a Distressor. The unit is reallyawesome! I've used it on guitars, bass, roommics, vocals it works great on everything. I've used it on records I've made with Beck, U2, Etta James, Hole and lots of others.” Joe Chicarelli
“After buying a Distressor I had an epiphany. Having used software plug-ins for years I often didn’t hear or understand the affects of various controls. After getting my Distressor,and using it and hearing the obvious affects of the attack and release controls, I was able to go back and use the Plug-ins with a newunderstanding.” (Email)
"One piece of gear I definitely recommend is a compressor called the Distressor. It's reallygreat for just about everything and if you had to use just one compressor you could probably get awaywith just using that." Mitchell Froom
“I sold a couple of 1176's and have replaced themwith the Distressors, which do a great job of emulating the 1176's. Michael Wagener “(Ozzy Osbourne, Extreme, Metallica)
“In general, I really like where Dave Derr’s ear leads him; one of pro audios trulyindependent thinkers, I’m a huge fan of the box (the Distressor): I use it for bringing up the “goosh” on ambient sources, and for saturating snares, toms, and kicks.” George Massenburg
Comments About the FATSO Jr
“In a word, the FATSO is a very good answer to what a lot of people loathe about digital recording. It smoothes out the sharp, brittle edges to exactly the extent you choose, and fills in the hairline cracks just right. I use one on almost every mix I do. I could easilyuse one and possibly two more.” George Massenburg
“People used to have to hunt for old, expensive gear to get the kind of sounds that the FATSO gives me.” Ed Cherney (The Rolling Stones, Bonnie Raitt, Bob Dylan, Eric Clapton, Jackson Browne, Susan Tedeschi, Etta James, … et al)
Best new Signal Processor-EQ AES Awards - "Empirical Labs Fatso took this category, despite the introduction of a varietyof cool newprocessors. Who can resist the best aspects of analog tape combined with great compression" EQ Magazine
"The winner of the highly -coveted, ‘I'm going to write you a check right after the showaward’ was picked up byEmpirical Labs for its FATSO processor.’ Craig Anderton
LIL FREQ
“HeyDave… so I got the box, plugged it in on an Etta James vocal that I was having problems with… and it $#$%^&* rocks. This is a great box, my friend. I can see anybodywith a DAWwanting to use this thing. I am using the shelving, DS’ing and transformer out, and I am just thrilled. Congratulations. It absolutely complements the digital crap that I am forced to use…wooo hooo.” Ed Cherney
"I finally got to hear Empirical Labs’ Lil FrEQ, a monster that will destroy the way you think about EQ. This single-channel unit has two shelving bands, tunable low cut, four parametric bands, dynamic EQ for de-essing and direct box input—all noiseless and distortion free. Best of all, its smooth processing is absolutely addictive. Sweet! " George Peterson (Mix Magazine)

DISTRESSOR
FEATURES
¾ Classic knee sound - With modern noise specs and improved performance. Really grabs.
¾ Programmable analog distortion/warmth - helpful in the pristine but unforgiving digital world.
Three audio modes providing user programmable, warm harmonic distortion. Emphasized tubelike, 2nd harmonic in clean and Distort 2 mode. In Distort 3 mode, the distortion becomes
dominated by 3rd harmonic, more similar to tape.
¾ Distortion indicator lights - A 1% LED and a "Redline" (3%) LED. No hard clipping until a few
dB past "Redline".
¾ Advanced built-in sidechain EQ - High mid band emphasis prevents harsh, edgy guitars or
vocals from hurting innocent ears. Low cut keeps the low "sum & difference" frequencies from
pumping the upper frequencies of source material.
¾ Fool proof operation - Even though there are 384 possible settings (not counting knob settings),
it's almost impossible to get a bad sound. Keep all knobs on 5 or 6 (around middle) with ratio at
6:1 and you won't go wrong.
¾ Eight unique curves - 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 release shape. Most exceptional is
the 10:1 "Opto" ratio which uses separate circuitry to emulate the oldest (and valued) "light
controlled" devices, such as the LA-2A etc. See manual to emulate other compressors of old.
¾ Discrete and integrated combination - the best of speed/linearity with repeatability. Hand tested
& selected components.
¾ Huge knobs with high resolution numbering - For easy readability and repeatable settings.
They also go to 10
¾ Locked, calibrated, output level - Allows speed in setting tape and live mix levels.
¾ Stereo Strappable
¾ Switchable 115/230 volt operation - Extra fuse provided inside unit.
¾ Over designed power supplies - Runs cool, allowing cabinet to be sealed - without heat vents.
Long life components.
¾ Single height and light weight - Classic sound in a small, extremely reliable package.
¾ True bypass - Know what it's really doing. All contacts doubled up for maximum reliability. No
internal audio connectors.
¾ XLR and 1/4" phone ins and outs - XLR fully balanced, transformerless design, pin 2 hot.
Changeable by user to pin 3 hot!
¾ All metal film and Roederstein resistors in the audio path - top quality components. Many
military spec. parts.
¾ Interface and features found nowhere else.
¾ Hand wired, calibrated in USA. Shipping weight 12 Lbs.
SPECS
Freq. response is 2 Hz to 160 kHz in clean audio mode (+0, -3 dB). Response is shaped in
distortion modes (Dist 2, Dist 3).
Dynamic range 110 dB from max. output to min. output in 1:1 mode. Greater than 100 dB signal
to noise in distort 3 mode.
Distortion ranges between .02% and 20% depending on distortion mode and release times set
on front panel.
DC coupled output - High quality input caps.
Time constants - Attack range 50uS - 30mS. Release range .05 sec to 3.5 seconds. Release
goes up to 20 seconds in 10:1 “Opto” mode.
Power Consumption – Typical is 10 Watts, maximum is 14 Watts.
Each "ratio mode" of the Distressor sets both the threshold and the ratio, in the standard sense of the
word. This was done to provide an easy to set, yet versatile group of curves. The 1:1 mode provides no
compression, but allows the audio to pass through the "warming" circuits of the unit (we'll get to the
distortion modes in a moment). Ratio's 2 through 6 are general purpose curves great for tracking. The
2:1 and 3:1 ratios are "parabolic" knees - very gentle curves that won't typically go into hard limiting and
therefore, also won't provide absolute overload protection. Ratios 4:1 and 6:1 have steeper knees and
are good general purpose curves that gradually move towards hard limiting, "nailing" the signal in its
place. The ratio of 6:1 is very useful for vocals, bass, and acoustic instruments. It has an easy slope at
first until after the knee, where an increasing ratio "musically" limits the peaks of the signal before
damage is done. The 6:1 and 10:1 Opto ratios employ shorter knee limiting, reminiscent of some old
classics from the 60's and 70's (see Classic Emulation).
"Nuke" is a different story. The "Nuke" ratio was developed for room mics, but we have since found it
useful in many areas. "Nuke" has a medium threshold but when the signal hits it, a nuclear blast won't
budge the output level. It is brick wall limiting, keeping any normal signal within 1 dB or so. Just patch
in a room mic while recording drums (or other instruments) and slam the meters. Try attack on 4 and
release on 2. The release curve of "Nuke" is logarithmic, meaning it lets off quickly at first and then
slows. This release curve is a big part of the Distressor's sound. Experiment with the release times this guy can release really fast without too much crackling, even on bass. 20:1 can be used similarly to
"Nuke". Each of these curves again has their own feel to them, with the release slopes slightly altered,
and the knees falling in slightly different places. Most exceptional are the 2:1, 10:1 and Nuke ratios,
which employ special detector circuitry.
Just what is a soft knee?
A "soft knee" is a compression curve where the first few dB of gain reduction occur at very low ratios,
gradually increasing as the signal increases (gets louder). This makes the onset of compression very
hard to detect. The knee usually extends for a few dB and gradually flattens out toward a final ratio. All
curves with the exception of 20:1 and "Nuke" have dominant knees. The 2:1 ratio has a knee that can
be as long as 30 dB, depending on attack and decay settings.
Classic Emulation
Since the unit is based on the oldest compressor topology, the unit can be made to sound very similar
to older classics. The nonlinear nature of the older gain control elements of opto-couplers, FET's,
pentode (or triode) tube bias or "mu" modulation, etc., can be closely emulated if proper settings are
used. A special "Opto" mode has been provided in the 10:1 ratio.
Some Examples:
* To simulate the opto-VCA models of old (the LA-2A, LA-3A, LA-4A), try 10:1 "Opto" ratio, with attack
on 10, release on 0, Det HP on. Adjust input and outputs to your taste. Keep the attack above 4 to
keep the OPTO flavor. Faster attacks will give you a more aggressive sound. Remember our LED
metering deflects much faster than the old VU's so don't be afraid to hit the unit quite hard (10-20 dB of
compression on peaks). To emulate tubes, try Dist 2 & 3 mode, but let your ears be your guide.
* For a classic “Over E-Z” type sound, try ratios 2:1 thru 6:1, att 9, release 2, clean mode.
* 1176LN 6:1, Att 0 - 3.5, rel 1 - 10.5. Use ratios 3:1, 4:1, 6:1, 20:1 to emulate 4 1176LN ratios. Clean
mode is appropriate (Dist 2 or 3 off). Remember that the 1176LN attacks extremely fast and you must
keep attack under 4 max. A familiar sound is 6:1, att2, rel 4.
* Old Fairchild IGFET - 6:1 att 3-5, rel 2 - 7 (start with att 4 and rel 4)
Due to the transformerless design, you will maintain a low transient intermodulation distortion, but will
get the warming grunge of 2nd and 3rd harmonic distortion, if distortion modes are enabled. Also,
unlike some of the older units, the Distressor is uniform and predictable from one unit to the next.
Precise factory calibration assures that if you go from one Distressor to another, these settings will all
sound the same.
Empirical Labs would like to thank Universal Audio for not only creating classic audio gear, but for
kindly allowing us to refer to their model numbers. As they say “Once a classic, always a classic.”
