The 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 “boink” and tame sound reflections that smear detail.
The microphone features a new no-feedback amplifier capable to work properly on 600 Ohm load. 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 headbasket is used to reduce internal sound reflections between the grille and the capsule that smear midrange and high frequency detail - the result is a clear and natural mid and high frequency response.
However, it entrusts additional requirements to the careful handling: it is highly recommended to use a pop filter to protect the capsule from dust spittle.
