Sonodore multi pattern studio microphone MPM-91
The Sonodore MPM-91 is a multi pattern microphone for universal applications.
The aim of the design of this microphone was to design a spot microphone with a natural
and neutral sound with a good impulse response.
The sound of the MPM-91 is very alive, but not too sharp or metallic!
MPM-91 fet is a superb general-purpose microphone for all kinds of single instruments
Therefore, this microphone can be used for many diverse applications in professional
At the heart of the microphone is a 1" dual mylar Neumann style capsule.
The polar pattern can be set infinity between omnidirectional, cardioid, and figure 8.
The MPM-91 will be supplied with the low distortion and with listening tests optimized
Only materials of the highest quality are used to ensure maximum reliability under tough
professional use. This means:
- use of gold-plated contacts only
- electronic components are selected for their proven quality in audio specific
equipment, handpicked, and individually tested.
- specially coated circuit boards for optimal protection against damp and moisture
- use of a special process for the production of printed circuit boards, which ensures
the purity of the copper pathways, resulting in greater stability and performance of
the circuit design.
- The electronic circuit and components are optimized with listening tests.
As part of the initial Sonodore philosophy, the microphone is 'active' powered via a
separate power supply PS-71 or PS-71D, instead of using standard phantom
power. Phantom-fed microphones are inherently less suitable for high-quality audio usage
since they work as compressors: when, for instance, high dynamics are required,
strong demands are made on the current supply of the phantom.
As a result, the current supply drops drastically and the stereo image and frequency
response collapse with it.
To avoid this, the MPM-91 is available in a version with a separate power supply which
allows a high-grade and exceptionally low-distortion amplifier to be placed directly in the
With active powering, the microphone current flows through an separated wire.
The microphone is supplied with:
- Rycote suspensions USM
- VAN Damme Tour grade XKE starquad microphone cable, Neutrik gold contact connectors.
- or the van den Hul Integration Hybrid cable van den Hul.
- Aluminium case
