BEYERDYNAMIC OPUS 67 SUPERCARDIOID DYNAMIC MICROPHONE

Dynamic clip microphone for drum miking

The Opus 67 dynamic microphone has been designed for closemiking of drums such
as Toms and Congas. The new patented microphone clamp allows easy mounting to
the instrument.
The flexible gooseneck ensures optimal positioning to suit both musician and sound
engineer

Features:
Dynamic microphone for Toms and Congas
Very high gain-before-feedback
High SPL capability
Unique double-spring clamp system
Flexible gooseneck for optimum positioning
Small, rugged construction for on-tour applications
Supplied with storage bag

Precise artistic work deserves precise artistic craftsmanship. A classic by now, the CMS Series CK 1 capsule from AKG was a best seller from the moment it was launched in 1969. Comprising a range of interchangeable capsules and preamps as well as then innovative, dedicated accessories, the CMS Series from AKG quickly became a legend. It was discontinued in 1993. Responding to growing demand from recording engineers, AKG decided to produce the C 451 B with identical acoustical behaviour of the popular original C 451 EB + CK 1 microphone again, with dramatically improved specifications and outstanding price/ performance. The capsule of the new version is fixed permanently to the preamp to eliminate the mechanical problems of the screw joint. Using an extremely light diaphragm, the new C 451 B is almost totally insensitive to handling noise. An all-metal body provides excellent protection from RF interference and the microphone is rugged enough to give excellent results even under very harsh conditions.

The C 451 B is an excellent tool for accurately capturing signals rich in transients such as drums, overhead miking, or other instruments with a percussive sound. The airy sound, high overload limit of the capsule and electronic circuitry, and improved engineering details of the C 451 B are a solid foundation for creating another legend.

The matched pairs consist of two microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 200 Hz to 15,000 Hz of the individual frequency response when used in cardioid mode and are selected from a large quantity of individual microphones using the described criteria by using a proprietary computer program.

Using this matched pair for stereo recordings utilizing various techniques will provide for a good and stable balance without frequency-dependent shifting of the stereo panorama.

The kit includes all the standard accessories of the individual package along with a stereo bar and proof of performance charts in an attractive carrying case (Soundtool case, middle size).
