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.

The DMK57-52 Drum Mic Kit is a conveniently packaged selection of microphones and mounts, designed to offer a complete core package of microphones for recording and performing drummers at a great price. The Drum Mic Kit includes three SM57 microphones, one Beta 52 microphone, three A56D drum-mounting systems, and a lightweight and durable carrying case.

• Tailored frequency response provides drums, guitars, vocals, and horns with studio quality sound
• Uniform supercardioid pattern for high gain-before-feedback and superior rejection of off-axis sound
• Hardened steel mesh grille that facilitates use of proximity effect and resists wear and abuse
• Neodymium magnet for high signal-to-noise ratio output
• Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
• Frequency response: 50 to 16,000 Hz

The D 40 with its solid all-metal body will stand up to the hardships of night-after-night onstage use "with a smile“.
The Varimotion diaphragm deep-drawing process allows the diaphragm itself to be fine-tuned with no need for tuning resonators, leading to a quantum leap in audio performance.
The transducer is protected by a sturdy wire-mesh cap and takes extremely high sound pressure levels with ease.
An integrated stand adapter and standard H 440 mounting bracket for snare drums, tom-toms, etc. make the D 40 a highly versatile tool for use on drums, percussions, wind instruments, and guitar amps.
