Oktava MK-519
Studio condenser microphone with enhanced acoustical characteristics
|
|
|

Overview
|
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.
