The JSC Oktava MK-519 features a large 27.5 mm condenser capsule with cardioid pattern using an all-brass backplate construction, precision-drilled pattern control holes and optimal 5 micron gold-plated diaphragm.
An isolation mount / diffuser is installed at the base of the capsule mount to reduce external vibrations.
The MK-519 provides a very high sensitivity and extremely low self-noise level, provided by a high polarizing voltage (about 100 V). The single layer head basket helps to reduce internal sound reflections between the grille and the capsule resulting in clear and natural mid and highs.
It is recommended that a suitable pop filter be used at all times to protect the delicate capsule.
