The CM7 G (Glass Tube Switchable) Suprema combines authentic vintage sound with unprecedented versatility, featuring a switchable cardioid mode relay engineered inside the mic capsule compartment plus eight different polar patterns found in a vintage M49, making it like having two microphones in one.\u003c\/p\u003e\n\n\u003cp\u003eThe CM7 GS with K47 capsule delivers a balanced tone with detailed midrange and smooth highs, perfect for vocals and instruments. Its innovative hard-switched cardioid mode produces a smoother, more full-bodied sound, with the pattern switch located on the PSU but the actual switch point positioned directly below the capsule compartment. The authentic three-layer grille design features outer large mesh, inner medium mesh, and fine mesh sandwiched between, creating acoustic interplay with the capsule and functioning as a Faraday cage. The precision K47 dual-membrane capsule features a brass backplate hand-milled in Switzerland to the original 15\/10000th inch specification within one-micron tolerance—a modern upgrade from the original M7's which had up to 0.0002\" tolerance.\u003c\/p\u003e\n\n\u003cp\u003eThe CM7 GS is equipped with three mounting isolation rims providing improved ground isolation. Capsules are gold-skinned in Germany by master craftsmen. The NOS Telefunken 800 series glass tube is a modern derivative of the vintage steel tube, using the same system construction but in a package less likely to become microphonic. The transformer is a historic recreation wound to original Braunbuch specifications using NOS laminations with authentic vintage Mu-Metal and larger bobbin specs from early \"Large Badge\" U47s. Teflon wire insulation replaces problematic PVC for 100% reliability. Wunder Audio has enhanced their design with Suprema Silver Gold Oil capacitors featuring 99.99% silver and 1% gold metallization, creating exceptional image depth, enhanced sound staging, air, and transparency with tighter focus and less grain. The proprietary PSU features military-spec Grayhill switch for reliable pattern switching, universal voltage compatibility, and complete RF\/Wi-Fi interference shielding.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLarge-diaphragm tube condenser with Glass Tube Switchable technology\u003c\/li\u003e\n\u003cli\u003eK47 dual-membrane capsule with balanced tone, detailed midrange, and smooth highs\u003c\/li\u003e\n\u003cli\u003eSwitchable cardioid mode relay inside capsule compartment for smoother, full-bodied sound\u003c\/li\u003e\n\u003cli\u003eEight different polar patterns (vintage M49 configuration) plus hard-switched cardioid\u003c\/li\u003e\n\u003cli\u003eTwo microphones in one: vintage U47 cardioid + multi-pattern versatility\u003c\/li\u003e\n\u003cli\u003ePrecision K47 capsule with Swiss-milled brass backplate (one-micron tolerance)\u003c\/li\u003e\n\u003cli\u003eModern upgrade: 15\/10000th inch specification vs original 0.0002\" tolerance\u003c\/li\u003e\n\u003cli\u003eThree mounting isolation rims for improved ground isolation\u003c\/li\u003e\n\u003cli\u003eDiaphragm stretched and glued to rim, never screwed to backplate\u003c\/li\u003e\n\u003cli\u003eGold-skinned capsules crafted in Germany\u003c\/li\u003e\n\u003cli\u003eThree-layer grille mesh with Faraday cage properties\u003c\/li\u003e\n\u003cli\u003eNOS Telefunken 800 series glass tube (modern derivative, less microphonic)\u003c\/li\u003e\n\u003cli\u003eHistoric transformer with vintage Mu-Metal and NOS laminations\u003c\/li\u003e\n\u003cli\u003eLarger bobbin specs from early \"Large Badge\" U47s\u003c\/li\u003e\n\u003cli\u003eTeflon wire insulation for 100% reliability\u003c\/li\u003e\n\u003cli\u003eSuprema Silver Gold Oil capacitors (99.99% silver, 1% gold)\u003c\/li\u003e\n\u003cli\u003eEnhanced image depth, sound staging, air, and transparency\u003c\/li\u003e\n\u003cli\u003eProprietary PSU with military-spec Grayhill pattern switch\u003c\/li\u003e\n\u003cli\u003eUniversal voltage compatibility without jumper switch\u003c\/li\u003e\n\u003cli\u003e30-turn precision trim pots for voltage fine-tuning\u003c\/li\u003e\n\u003cli\u003eComplete RF and Wi-Fi interference shielding\u003c\/li\u003e\n\u003cli\u003eIdeal for vocals, acoustic instruments, drums, and versatile recording applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: Large-diaphragm tube condenser microphone (Glass Tube Switchable)\u003c\/li\u003e\n\u003cli\u003eCapsule: K47 dual-membrane capsule with Swiss precision brass backplate\u003c\/li\u003e\n\u003cli\u003eCapsule Specification: 15\/10000th inch rim height, one-micron tolerance\u003c\/li\u003e\n\u003cli\u003eCapsule Finish: Gold-skinned in Germany\u003c\/li\u003e\n\u003cli\u003eIsolation Rims: Three mounting isolation rims for improved ground isolation\u003c\/li\u003e\n\u003cli\u003eTube: NOS Telefunken 800 series glass tube\u003c\/li\u003e\n\u003cli\u003ePolar Patterns: Eight switchable patterns plus hard-switched cardioid mode\u003c\/li\u003e\n\u003cli\u003ePattern Switching: Internal relay below capsule compartment\u003c\/li\u003e\n\u003cli\u003eGrille: Three-layer mesh (large, medium, fine) with Faraday cage properties\u003c\/li\u003e\n\u003cli\u003eTransformer: Historic recreation with vintage Mu-Metal, NOS laminations\u003c\/li\u003e\n\u003cli\u003eTransformer Bobbin: Large bobbin (early U47 spec, 1\/8\" larger)\u003c\/li\u003e\n\u003cli\u003eWire Insulation: Teflon (upgraded from PVC)\u003c\/li\u003e\n\u003cli\u003eCapacitor: Suprema Silver Gold Oil, 1uF capacitance\u003c\/li\u003e\n\u003cli\u003eCapacitor Metallization: 99.99% silver, 1% gold\u003c\/li\u003e\n\u003cli\u003eCapacitor Purity: Silver min. 99.97% typ. 99.99%;
