Schoeps MSTC 64 U

ORTF Stereo Microphone


The Schoeps MSTC 64 U is particularly impressive in that it usually also gives very good results without spot microphones. In addition, its placement is relatively unimportant, making it suitable for the rather inexperienced or hasty user. Set-up is quick and easy because only a single stand and cable are required and the capsule distance and the offset angle of the capsules to each other don’t need to be adjusted.

At the output of the MSTC 64 is an XLR-5M plug to which e.g. the stereophonic cable KS 5 U, or the breakout AK SU/2U is connected.


  • Stereo microphone for recording using the ORTF technique
  • excellent stereophonic characteristics: very good localization, very good spatial quality
  • preferred use as a main microphone for recording ensembles and choirs or as a stereophonic spot microphone

The MSTC 64 is one of SCHOEPS’ bestsellers. Its compact elegance and excellent spatial quality make it a classic in the sound engineer’s standard portfolio.

This microphone consists of a T-shaped two-channel microphone amplifier, in which two paired MK 4 cardioid capsules are screwed onto. They are arranged at a distance of 170 mm at an angle of 110° to each other, as required for the ORTF method.


For outdoor use, a wind basket, e.g. the CINELA Albert or a CINELA OSIX with a single windshield is recommended.

Alternatively, the ORTF Outdoor Set can be used which employs single CCM microphones in an ORTF arrangement.
