A valve condenser microphone with cardioid polar pattern is the successor to the MK-219/319. The same capsule of the MK-219 in conjunction with the matching valve cascade provide the richer and more natural sound.
The feeding device BP-100 is used to power the amplifier's anodic and filament circuits and for creation of polarizing voltage on the microphone capsule. The device works from the mains supply of di-rect and alternating current at the frequency of 50/60 Hz, 85-242 V.
Textured matt-black finish. Factory-matched stereo pairs are available.
It is recommended to use the shock mounts AM-50, AM-60/27 "Spider"
Requirements to acoustic parameters of stereo pairs:
- Their sensitivity at the frequency of 1000 Hz may vary no more than 2dB
- The difference between sensitivity at the frequency range must be no more than 3dB
