Neumann U87 is probably the best known and most widely used studio
condenser microphone. Originally released in 1967 as the solid
state version of the valve U67, the Neumann U87 condenser microphone
has been the industry standard studio condenser since the 1960's.
It is a large dual-diaphragm condenser microphone with three directional
patterns: omni, cardioid and figure-8, all of which are selectable
with a switch below the head grille. At the back of the mic is
a 10 db attenuation switch and a low frequency roll off making
the mic capable of dealing with most studio tasks though it's
probably most famous for its use as a vocal microphone.
