a perfect candidate for building up your microphone collection. The Austrian-developed LCT 450 features a
1-inch cardioid condenser capsule, it delivers everything you would expect from a studio microphone: A warm,
round and full bodied sound with first class transient response and silky sweet high end, which makes it an
impeccable choice for vocals and all sorts of acoustic instruments.

The cardioid polar pattern perfectly qualifies the LCT 450 for coincident (XY) and near coincident (ORTF) stereo
recording techniques such as classic drum & percussion overheads, string sections, choir, grand piano or even
stereo vocal recordings, when spaciousness and ambience is needed.
