MSTC 74 U

ORTF Stereo Microphone

New 2022 model - now available

Features

  • New 2022 model with completely renewed electronics and new design
  • 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 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, 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.


Order number

  • No. 139901 MSTC 74 U (with capsules)
  • No. 132014 MSTC 7 U (without capsules)

Description

The MSTC 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 be adjusted.

At the output of the MSTC 74 is an XLR-5M plug to which e.g. the stereophonic cable KS 5 U, or the breakout AK SU/2U is connected.

The MSTC 7 (No. 132014) comes with:

  • No. 232014, MSTC 7, stereo microphone
  • No. 161105, SG 20, stand clamp
  • No. 152202, AK SU/2U, breakout cable

The MSTC 74 (No. 139901) also includes:

  • 2 * No. 231015 MK 4, matched

For outdoor use, a wind basket, e.g. the CINELA Albert or a CINELA OSIX with single windshields W 5 D or W 20 is recommended.

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