{"product_id":"microtech-gefell-m990-184975","title":"M990","description":"\u003ch3\u003eA Tube Microphone Designed for the Constraints of Radio and the Richness of Ensembles\u003c\/h3\u003e\u003cp\u003eThe M 990 follows the great tradition of tube condenser microphones used in production and broadcasting, where reliability and intelligibility are paramount. It is particularly suited for \u003cstrong\u003echallenging radio activities\u003c\/strong\u003e and \u003cstrong\u003eorchestral recording\u003c\/strong\u003e, two contexts that require both natural rendering, controlled presence, and the ability to handle significant dynamic range. The design highlights a \u003cstrong\u003enew capsule\u003c\/strong\u003e and a tube preamplifier with a proven architecture to achieve a sonic character that is both expressive and usable in a modern mix.\u003c\/p\u003e\u003ch3\u003eIntended Users and Applications in Studio or Live Recording\u003c\/h3\u003e\u003cp\u003eThe M 990 is aimed at sound engineers, production studios, demanding podcasters, and control rooms seeking a \u003cstrong\u003ehigh-end vocal microphone\u003c\/strong\u003e capable of enhancing timbre without harshness. Thanks to its cardioid pattern and sensitivity, it is suitable for spoken voice recordings (radio, dubbing, voice-over) as well as singing voices, limiting room pickup while maintaining airiness. In orchestral setups, it can serve as a section microphone, spot mic (woodwinds, brass), or close ambiance mic when a stable image and clear midrange are desired. Its tube signature is also relevant on demanding acoustic sources whenever body and a sense of depth are wanted without overemphasizing sibilance.\u003c\/p\u003e\u003ch3\u003eDesign, External Power Supply, and Key Points for Clean Integration\u003c\/h3\u003e\u003cp\u003eThe core of the M 990 is a capsule equipped with a \u003cstrong\u003elarge gold-plated plastic diaphragm\u003c\/strong\u003e, designed to capture details generously, with a stated frequency response of 40 to 18,000 Hz. The tube preamplifier uses an \u003cstrong\u003eEF 86\u003c\/strong\u003e (pentode configured as triode) selected for its sonic qualities, providing the typical tube circuit depth while maintaining good definition.\u003c\/p\u003e\u003ch4\u003ePower Supply N 920.1: Stability, Connectivity, and Mains Adaptation\u003c\/h4\u003e\u003cp\u003eThe microphone operates with an \u003cstrong\u003eexternal power supply N 920.1\u003c\/strong\u003e (essential for a tube microphone), responsible for delivering the necessary voltages, including a continuous voltage supply rated at 120 V. The unit accepts mains voltages of \u003cstrong\u003e115 V or 230 V\u003c\/strong\u003e and frequencies of \u003cstrong\u003e50 Hz or 60 Hz\u003c\/strong\u003e, suitable for fixed studio use or live performance. It features a \u003cstrong\u003epower on\/off switch\u003c\/strong\u003e, a microphone output via \u003cstrong\u003e7-pin Tuchel connector\u003c\/strong\u003e, and an audio output via \u003cstrong\u003e3-pin XLR\u003c\/strong\u003e, with an integrated mains voltage selector. For long cable runs, a recommendation is provided: beyond \u003cstrong\u003e50 meters\u003c\/strong\u003e, it is advised to have the \u003cstrong\u003efilament voltage\u003c\/strong\u003e adjusted by a technician to \u003cstrong\u003e5.8 V\u003c\/strong\u003e to maintain optimal operating conditions.\u003c\/p\u003e\u003ch4\u003eSound Capture: Headroom, Noise, and Dynamics\u003c\/h4\u003e\u003cp\u003eWith a \u003cstrong\u003emaximum SPL\u003c\/strong\u003e rated at \u003cstrong\u003e119 dB\u003c\/strong\u003e (for total harmonic distortion less than or equal to 0.5%), the M 990 can handle strong sources without collapsing, which is appreciated on brass, light percussion, or powerful voices at reasonable distance. The self-noise is given according to two measurements (CCIR and A-weighted), and the signal-to-noise ratio is also specified, useful information for choosing a microphone suited to very detailed recordings (close vocals, classical, ambiance). The overall aim is a coherent studio compromise: \u003cstrong\u003etube musicality\u003c\/strong\u003e, \u003cstrong\u003elevel of detail\u003c\/strong\u003e, and \u003cstrong\u003edynamic
