BLUE BALL HANDMADE CARDIOID DYNAMIC MICROPHONE

Meet the Ball, the latest addition to our award-winning family of
hand-built microphones. So-named for its unique shape and inimitable
Blue styling, The Ball is our first offering in the dynamic mic category.
But a phantom-powered dynamic? Yes. And no. Most recordists know
that conventional dynamic mics do not require external DC power.
Rather, they employ a relatively simple circuit and derive their output
voltage through electromagnetic induction. While this makes them rugged,
reliable and easier to operate than their electrostatic counterparts, they
also present the user with a unique set of problems. Chief among these
is frequency-dependent variable resistance which has dramatic effects
on the transducer?s acoustic balance, phase coherence, noise specification
and overall output. Our engineers solved this problem by incorporating
a phantom-powered proprietary active balancing circuit in the Ball?s output
stage. This circuit maintains a constant pure-resistive 50-ohm load across
the useable frequency spectrum yielding an exceptionally smooth and open
sound previously unheard of in a dynamic microphone. Additionally, as a
dynamic mic, the Ball is capable of handling extremely high sound pressure
levels without distortion, making it the ideal choice for studio, stage, broadcast,
film or any other applications where reliability, versatility and the utmost
sound quality is required.

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).
