Black Box Analog Designs MM-1 PRE/DI  From Black Box

The MM-1 Vacuum Tube Preamp is an entirely new approach to capturing audio. It is not based on any existing circuit but designed from the ground up, using the best parts and ignoring all of the standard ideas of how a preamp “should work”. The result is an incredibly versatile piece of gear that not only sounds amazing but shatters the idea of what a preamp can do!

Manufacturer's Description from Black Box

Tonal Control Like Never Before

Until now, a preamp simply amplifed the signal; you essentially got one sound and the ability turn it up or down. The MM-1 on the other hand allows you to drastically shape the response curve of the unit without using an EQ, control the harmonic content from pristine to full on saturation and even control the dynamics without a compressor!

All of the shaping is done at the tubes and from the constantly variable interaction between stages allowing you to dial in virtually unlimited tonal possibilities. You can find the sweet spot of any microphone and instrument easily and naturally.  The response curve of the Pentode stage alone gives you a huge amount of control over the tone. Coupled with the independently controlled Triode stage you have virtually unlimited tones at your fingertips.

 

Harmonics for days…

There seems to be an obsession with THD when it comes to mic pre designs. Manufacturers boast about how “clean” their designs are and how low the THD is as if these harmonics are the plague yet the fastest growing trend in plug-in design is creating plug-ins that add back these harmonics! Tape, console, tube and various analog emulations that add pleasing harmonics and distortion are more in demand than ever! Why? Because the human ear LOVES harmonics! So why are manufacturers bragging about how they have managed to remove them from the design while mixers are having to add more emulations on to compensate? We have no idea but we certainly aren’t! We love harmonics and our pre has been designed to SOUND amazing! We give you the ability to add a ton of rich, beautiful and musical harmonics and give you unprecidented control over it!

All Tube, All Analog

Our entirely analog audio circuit uses only tubes for amplification and is entirely free of op amps, ICs and transistors! From precisely, hand matched resistors and capacitors to custom wound transformers, every part is selected and built for the absolute highest quality sound.

Real Power

We all know that a piece of gear is only as good as its power supply! For that reason, our preamps use a massive toroidal to supply 350v of pure, linear power to get the most out of the tubes. Real power means real sound!

Features:

  • Independently controlled Pentode and Triode tube stages
  • Custom wound input and output transformers
  • Entirely analog audio path (No ICs or Op amps)
  • Switchable input impedance at input transformer 
  • 5 position, gentle and musical roll off
  • “Air” circuit from the HG-2
  • Two response modes
  • 15 db pad
  • Linear power supply
  • Passive output attenuation control
  • 48v Phantom power 
  • Dual voltage

About Manufacturer

"While most things these days are made over seas in huge factories with the singular goal of maximizing profits by cutting corners and using the cheapest components, Black Box Analog Design does things differently.

In fact we take a different approach to most things. We are not interested in creating clones of old gear or building derivatives of popular gear. We are interested in creating gear that does something that hasn’t been done before, addresses a need we come across in the studio and takes a new approach to a problem or design.

We didn’t start out as gear designers. We come from the studio world and years ago, our quest to solve certain problems we came across lead us
to begin tinkering with circuits of our own. Since we came from an audio engineering background and not a circuit design background we weren’t influenced by standard designs or restricted by thoughts of what we “should” do. Instead we allowed our ears to lead us in the right direction."
