The Sound\u003c\/h2\u003e\n\u003cp\u003eThe Kahayan 4K7 is a completely handmade tube condenser microphone built around the same components that defined the original U47 sound. An M7 capsule, a BV8 output transformer, and an EF86 tube, each manufactured to the exact specifications of this microphone  combine to deliver the linear frequency response, musical low-midrange character, and exceptional dynamic sensitivity that engineers have been chasing for decades.\u003c\/p\u003e\n\u003cp\u003eThis isn't a microphone built to a price point. It's built to a standard. Premium components throughout, custom-made exclusively for the 4K7, and assembled entirely by hand — every unit is a deliberate piece of craftsmanship, not a product off an assembly line.\u003c\/p\u003e\n\u003cp\u003eAs an authorized dealer, Pro Audio Reserve ensures your Kahayan 4K7 is genuine, backed by full manufacturer warranty and support.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- Section 2 --\u003e\n\u003cdiv class=\"par-section reverse\"\u003e\n\u003cdiv class=\"par-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0646\/4031\/9643\/files\/Kahayan_4K7_font_on_view_1.png?v=1772255948\" alt=\"Kahayan 4K7 tube microphone with power supply and shockmount\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"par-text\"\u003e\n\u003ch2\u003eThree Characters. One Microphone. Endless Versatility.\u003c\/h2\u003e\n\u003cp\u003eThe 4K7 includes a Character switch with three distinct voicings. Soft, Medium, and Hard  that fundamentally change how the microphone responds to a source. Soft mode delivers a silky, rounded top end that flatters vocals and acoustic instruments. Hard mode brings a more forward, present quality ideal for sources that need to cut through. Medium is the balanced starting point for when you want the pure character of the capsule and circuit doing their work without any additional coloring.\u003c\/p\u003e\n\u003cp\u003eCardioid and omnidirectional polar patterns expand your recording options further  use cardioid for focused, intimate captures or switch to omni for room ambience, ensemble recording, or situations where a more natural, open perspective serves the source better.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- Section 3 --\u003e\n\u003cdiv class=\"par-section\"\u003e\n\u003cdiv class=\"par-image\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0646\/4031\/9643\/files\/Kahayan_4K7_power_supply_1.png?v=1772255948\" alt=\"Kahayan 4K7 microphone aluminum body and capsule detail\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"par-text\"\u003e\n\u003ch2\u003eBuilt to Last, Packaged to Impress\u003c\/h2\u003e\n\u003cp\u003eThe 4K7 body is machined aluminum with a nickel finish  lightweight enough to position easily, built solid enough to handle years of professional use.
