Sound Pure's Take

Empirical Labs earned legendary status in the pro audio world with the Distressor, and when Dave Derr turned his focus to creating a dedicated channel strip, the result was the EL9 Mike-E. Combining a whisper-quiet, transformer-coupled preamp with a modified Distressor-style knee compressor and saturator, the Mike-E is an absolute tour de force for modern tracking and mixing.

The preamp section is a digitally controlled analog design that provides up to 74dB of ultra-clean, high-headroom gain. It uses a custom Lundahl input transformer that adds subtle depth and weight without masking transient detail. Whether you're tracking quiet acoustic instruments or driving dynamic mics on aggressive vocals, the Mike-E offers remarkably low noise, lightning-fast transient response, and precision stepped controls for exact recall.

 

Where the Mike-E truly shines, however, is its CompSat section. Derived from the iconic Distressor circuit, it gives you a soft-knee VCA compressor with preset multi-stage attack and release times optimized for vocals and instruments. Following the compressor is the switchable Sat (Saturation) stage, which generates rich second-harmonic distortion to emulate the warm, forgiving overdrive of vintage tape machines and vacuum tubes. Pair that with an onboard Mix control for instant parallel compression, and you have complete control over transient impact and harmonic character in a single box.

From Empirical Labs

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.

 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.

Mic Preamp

This is 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.

MIX - provides “parallel compression” technique achieved by mixing between the compressed and the dry (or uncompressed) signal. This can often help maintain transients and a sense of dynamic range while enhancing the low level nuances.

Other features include a front panel instrument input that allows the unit to function as an ultra-clean Direct Box and stereo-linking capabilities. Mike-E can also be combined with an EQ (such as the ELI Lil FrEQ), transforming it into one of the most powerful, flexible and complete channel strips on the market.

Mike-E’s Seven Circuits

1. Mic Preamplifier with super low noise and stepped gain switching.

2. Built in ‘Direct Box’, called the ‘Inst In’, offers unparalleled distortion, noise, and frequency response when pre-amping instruments.

3. ‘Colored’ 80Hz High pass filter emulates the warm low frequency cut of our favorite vintage equalizers.

4. Phase Switch to invert the audio signal 180 degrees.

5. CompSat offers both a musical Compressor/Limiter and a unique tape-like saturation circuit.

6. Emphasis high-frequency emphasis system softens high frequency ‘pile-ups’ and further the creamy color of the Mike-E.

7. Mix Control allows the blending of the Compressed/Saturated signal with the clean unprocessed “Dry” signal.

• Freq. Response is 3 Hz to 200 kHz on (No CompSat). CompSat is 3Hz – 150Khz. Optional Transformer output is 6Hz–80kHz.
