It is a condenser microphone, a small membrane, cardioid directivity. Ncessite a 48V phantom power supply It is a competitor of the Neumann KM 184; like him, its capsule is not interchangeable, unlike the KM 140 or Schoeps Colette series, which is cohrent with its price significantly infrieur (infrieur also of KM 184 but little). The spcifi noise level seems a bit high (<= 21 dB pondr A) but does not seem to me be dterminant in practice.

NOTICE GLOBAL

I have a stro pair for several weeks. I like the clarity that does not exclude low prsentes, but dfinies. I have various small-diaphragm mics Rode, Oktava, Avenson, Schoeps Schoeps CMC6 / MK21 clearly were the best so far. I believe that these can be an interesting alternative to Schoeps according to what records.
I did a comparison test with the Schoeps on the piano and in mono, AKG C414B with XLS-on nylon guitar, listen in the forum.
Given these comparisons, the quality-price ratio is amazing. The matte black finish is impeccable. They are provided with a box Pelican and tongs integrates with suspension.
