Awesome Mic Pre and Compressor!The Mike-E from Empirical Labs manages to do many things totally well! First and foremost, it's a modern digitally controlled microphone pre. An extremely low-noise transformer on the in amp keeps the signal nice, bulletproof, and clean. The next link in Mike-E's signal chain is the CompSat section, which is comprised of a Saturator, Compressor, Emphasis, and Mix control. These four elements come together to provide your tracks with anything from straight-up classic knee compression/limiting to coloring via compression with the Mike-E channel strip.

Amazing microphone pre
Mike-E is above all, a fine example of what a sweet preamplifier should be, chocked with unusual features to warm and soften the source, plus an excellent compressor/limiter. Mike-E offers incredible performance via the transformer-coupled microphone preamplifier, whose noise floor is far below any microphone's self noise. This super-low-noise transformer input amp section sports gain that is digitally controlled. This section comes standard with a shielded Lundahl transformer, but offers for a Jensen transformer also. The signal to noise far exceeds any microphone in existence, typically over 130 dB with the input shorted and 40dB of gain. Having used many microphone preamps over the years, we have implemented a one-of-a-kind stepped gain control that should be impervious to the normal flakiness that age causes to pots and detented switches. Counting the out gain of 14 dB, a total 74 dB of gain is available to the user with the CompSat section bypassed. A 48 Volt Phantom power is provided for condenser mikes.
One-of-a-kind compressor section
The one-of-a-kind 'CompSat' section is an uncompromising compressor and saturator circuit that offers versatile 'coloring', and classic knee compression. The exclusive CompSat section sets the Mike-E apart from all other microphone preamplifiers. It's comprised of four sections:
- SaturatorThis is a multi-stage soft clipping circuit. At lower levels, a triode type saturation affects the signal. As the level increases, a second one-of-a-kind clip circuit that includes Germanium semiconductors starts to more severely flatten out the peaks. An LED named "BAD!" indicates harder un-musical clipping.
- Compressor This is an uncompromising compressor/limiter circuit that allows detented control of attack and release for really simple repeatability. You adjust the amount of compression with the Drive knob, which adjusts the level going into the compressor. In ways, it is quite Distressor-like, but has other differing characteristics including a much longer available attack time, and more circuitry. Four ratios are provided, 2:1 being the gentlest with a long 20dB knee, good for subtle compression such as while tracking or on the Bus. Ratios 4:1 and 8:1 are steeper but still totally smooth with long knees. Nuke is completely steep (limiter like) and has a different attack & release shape.
- Emphasis The Emphasis is actually two circuits that surround the compressor and saturator. The Pre-emphasis boosts the high frequencies before the compressor and saturator (CompSat), soft clipping them sooner than normal, while a de-emphasis cuts the frequencies complementary after the CompSat. Emphasis has the added perk of improving signal to noise, and is the reason analog tape decks used emphasis to begin with.
- Mix Control The modern recording engineer often employs the technique of 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. Mike-E has a made in mix control to submix in the uncompressed signal to the compressed signal. As the user rotates the MIX control from full right to full left, he goes from the full compressed signal to the full dry signal (absent of any compression or saturation).
