Model SCU250
Professional Boundary
Microphone
DESCRIPTION
The SCU250 is an unobtrusive, uni-directional, surface-mount microphone
ideal for meeting rooms, conferences, and stage productions where minimum
visibility is ideal. The SCU250 provides full, rich reproduction of voice and
music and is well-suited in capturing the sound source and the immediate sur-
roundings. It has a low sensitivity to stage vibration and thumping noise and
has excellent user sound isolation feedback rejection.The SCU250 has a low-
impedance balanced output.The SCU250 features a heavy copper case with a
non-glare matte black finish, mounting keyways on bottom for hanging or for
attachment to the mounting surface, and a cardioid pickup pattern.The micro-
phone requires an external 9V - 52V DC phantom power supply and is ter-
minated by a standard male XLR with a built-in pre-amplifier.
