APPLICATIONS
The MC 840 microphone provides 5 switchable polar patterns for
universal studio applications. It has been designed without
compromise to capture every sound detail with absolute clarity and
purity. Applications for the MC 840 include recording orchestras
resulting in a superb transparent sound. Due to a switchable
2 position roll-off filter and a switchable pre-attenuation the
MC 840 is also suitable for close miking of instruments.
