AUDIO TECHNICA ATM350D Cardioid Condenser Instrument Microphone with Drum Mounting System

Cardioid Condenser Instrument Microphone with Drum Mounting System (5" Gooseneck)

Designed for use with drums, the ATM350D UniMount® mounting system gives you the tools to perform with confidence. The system features the ATM350a cardioid condenser microphone, a high-SPL mic that provides a clear, well-balanced response from any instrument. When teamed with the included AT8491D drum mount and strong, flexible AT8490 5" gooseneck, the mic can be securely fastened to the drum and positioned to stay where you want it. The drum mount’s unique spring-loaded mechanism clamps it tightly to a drum lug (without hindering your ability to adjust the lug) and provides excellent shock resistance for the mic; the gooseneck’s rigidity ensures that it won’t flop around no matter how aggressively you play.

The microphone’s cardioid polar pattern isolates the instrument by reducing side and rear pickup, and the switchable 80 Hz high-pass filter on the in-line power module helps control undesired low-frequency noise. The system also includes an AT8468 violin mount with hook-and-loop fastener and a protective carrying case.

• Low-profile mic design for minimum visibility

• Crisp, clear, well-balanced microphone response, even at high SPLs

• Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source

• UniMount® drum mount with unique spring-loaded mechanism attaches securely to a drum lug, and provides excellent shock resistance for the microphone

• Rugged UniMount® 5" gooseneck rigidly holds its shape, keeping microphone accurately positioned even during aggressive play

• In-line power module is equipped with a switchable 80 Hz high-pass filter to control undesired ambient noise

• Interchangeable elements available for hypercardioid and omnidirectional polar patterns

• Included violin mount with hook-and-loop fastener provides an additional mounting option

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.

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).
