At first glance, the Gefell M200 looks like a typical pencil microphone. But upon closer inspection, one immediately notices the incomparable fit and finish that comes with hand-made precision of German engineering. The sleek nickel-satin finish, combined with the sculpted control zone is clearly at another level.
As a modular system, each of the three microphone capsules may be separated from preamplifier. Inside the capsule housing is the M3 capsule, a hand-stretched 12.5mm (1/2”) 24-karat gold evaporated membrane with hand-machined back-plate. The M200’s smaller capsule has the distinct advantage of less diaphragm distortion for a more natural and uncolored response.
The use of a rugged ‘space-age’ ceramic housing assures stability and improves linear response as effects from temperature fluctuations are minimized. Ceramics have long been known for their ability to withstand heat or cold without the expansion and contraction associated with metals. This of course is a concern when attempting to maintain a precise gap between the membrane and the charged back plate.
To control ballistics and ensure a smooth axial response, the capsule top and side grills are actually made up of five separate meshes. The capsule housing is then mounted on a pedestal that simultaneously deflects unwanted body reflections away from the capsule while assuring a precise polar pattern is maintained. The careful control of phase cancellation benefits the M200 with both a more detailed and articulate rendering, while reducing unwanted noise from entering the capsule.
The microphone capsule amplifier employs a newly developed hybrid circuit topology. This features a transformerless, symmetrical output stage that yields both a very low self-noise and better than 148dB pressure handing.
On-board controls include a low-frequency roll-off that gently reduces rumble or run-away acoustic resonance in live settings. A 10dB pre-attenuation pad is used when extreme sound pressure levels are encountered.
