Gefell M300
Miniature pencil, cardioid studio condenser. The Gefell M300 is an exciting new microphone that combines the natural sound and detail of a gold evaporated 16mm diaphragm with 'space-age? advancements in mechanical and circuit design. The M300 is very versatile, exhibits very low self-noise, and is extremely stable and linear at all temperatures making it an ideal choice for critical recording and location sound for film and television production.
Development
Gefell is one of only a few companies in the world that today continues to develop and flourish in the area of test, measurement and instrumentation microphones. As with all advanced technology, the prerequisite for serious advancements follows demands from industries that have the financial resources to support the development. These are typically limited to industries such as aerospace, telecommunications and automotive. For music, one must capitalize on a technology trickle-down from these well funded sources in order to take advantage of these advancements.
The Gefell M300 is in fact a marriage of the latest 'space-age? technologies combined with the time-proven hand-made craftsmanship that still permeates every aspect of the Gefell factory.
The exceptionally small body gives immediate evidence that the M300 follows the course of measurement microphones whereby reducing body refraction for minimal field disruption is critical. But this is just the beginning: Upon internal investigation, several ingenious advancements become evident in the capsule, the housing and the newly developed pre-amplifier.
For instance, the use of ceramics is widely renown for its stability at extreme temperatures. Ceramics do not expand or contract like metals, making them very intriguing for use where critical gaps must be maintained. This is why NASA uses ceramics extensively on the space shuttle and why Gefell is leading the way in test and measurement. And yes, the M300 internal capsule housing is in fact made of ceramic to ensure a stable and repeatable rendering no matter what temperature, no matter what sound pressure.
As demands increase for greater articulation and lower noise, new electronics have been developed to meet the challenge. The M300 is literally an oxymoron that manages to combine high-output with low noise in an exceptionally small body.
Design Features
The Gefell M300 begins with a beautifully handcrafted body that is both slim and elegant. The dark bronze finish reduces glare making the M300 almost invisible on stage.
Inside, the microphone is split into two zones. The M3 capsule features a 16mm 24-karat gold evaporated diaphragm with Mylar (PE) substrate which provides an excellent balance between articulation, high impulse response and a warm natural frequency curve. The smaller capsule has the benefit of reduced membrane distortion, resulting in a more linear response as sound pressure levels are increased.
The capsule is constructed with a ceramic housing providing greater stability when subjected to temperature changes. This of course benefits the microphone with exceptional consistency and repeatability in even the harshest environments. The capsule is pressure-mounted on a damped-spring pedestal. This has the function of improving the cardioid polar response while reducing unwanted reflections thus minimizing phase cancellation. The compact body further advantages the M300 with reduced vortex and disruption around the mic, which results in greater detail and a more natural sound.
The capsule itself is protected against severe pop blasts with a triple-layer front mesh and dual-layer side mesh. Pick-up pattern is axial, whereby maximum sensitivity is realized at the front of the microphone while off-axis response is both smooth and musical. A slight 2.5dB ?presence rise? between 6kHz and 10kHz ads air, capturing subtle harmonic detail that is often lost as one moves off-axis.
To reduce noise, The Gefell M300 employs a newly developed circuit topology. This state-of-the-art design incorporates optical isolation of the power grid, for exceptionally low self-noise. Hash and ripple caused by voltage spikes from unfiltered 48V phantom power are eliminated resulting in ?clean noise-free power? for the capsule. The transformerless preamp delivers a pristine, natural response while the symmetrical output assures quiet and efficient performance and exceptional rejection against RF.
Using the M300
On first sight, one is immediately impressed at the M300's diminutive size. This benefits the engineer by allowing the Gefell M300 to be used in even the most difficult spaces. Furthermore, because of the added stability of the ceramic capsule housing and the precise cardioid pattern, the M300 is not limited to studio use, but may be used outdoors, under stage lighting and in high noise environments such as concert stages or for location sound.
This also makes the M300 an ideal choice in highly reverberant fields where a high degree of rejection may be desired to reduce noise or for live PA use to alleviate feedback.
Connection is simple with a standard 3-pin XLR and standard 48V phantom powering. The M300 comes with a standard mic clip. For applications where vibration-borne noise may be encountered, using the optional EA21 elastic suspension is recommended. The EA21 features a clamp-on system that provides secure retention of the mic, allowing complete placement freedom without worry. The M300 may be factory-ordered in stereo matched pairs for use with XY, ORTF and other popular recording methods.
Interpretation
The Gefell M300 is a miniature pencil microphone that is big on sound and performance. Advanced technologies such as the use of ceramics and optical isolation distinguish the M300 with greater stability and lower noise than others. These combined with a hand-stretched gold sputtered diaphragm yield a microphone that is easy to use, extremely linear and sounds great in just about any application.
The M300 is well suited for recording where the natural sound of the instrument is desired and is an ideal choice for solo instruments such as guitars and woodwinds, for percussion and for stereo orchestral and ensemble recording. The Gefell M300 comes in a beautiful hand crafted wood storage box.
