Multi-Pattern Tube Condenser Microphone

Built from the work InnerTUBE engineers had done to revise, simplify, and improve vintage tube circuits like the U-87 and 451 tube retrofits, the MM-2000 was a high-end multipattern tube condenser mic built around a hand-selected 6922 tube and “European” capsule.

The housing is a Maglite: solid, anodized, and acoustically neutral.

The mic provides a continuously-variable pattern selection control on the external power supply.

Switches on the body provide a -20dB pad, as well as a 3-position output-gain attenuator; because the mic provides a line-level output, the user can select -10dB and -24dB of gain reduction.

The mic has been discontinued; the current revision is known as the MM-2006.

EQ Magazine
I used it outside a kick drum in place of what would normally be a U 47-FET (about 1 foot outside the cutout of the drum head), again with excellent results. The mic has tremendous headroom and the line-level output was such that no mic preamp was needed. The end result was enough bottom that no additional EQ was required while the top end remained clear and clean.
On vocal again the MM-2000 rose to the challenge of both a screamer and a soft singer. The mic handled the screamer from a foot away with no hint of overload, while on soft vocals the sound was again huge while retaining the high-end clarity so often missing with expensive large diaphragm mics.

The InnerTUBE Audio MM-2000 is also known as: MM2000, magmic.

The mic was released in 2004.
