Setting 110° for ORTF is a different matter: the difference between 100° and 110° is invisible without a reference point, and an angular error translates directly into asymmetry in the stereo image between left and right channels. The Stereo Protractor solves this mechanically: engraved angle marks on the microphone mounting heads allow the exact included angle between mic axes to be set without a protractor, string line, or trial and error. TapeOp Magazine put it accurately in their review — 90° you can guess, 110° you cannot.\u003c\/p\u003e\n\u003ch3\u003eCompact Format for Tight Miking Situations\u003c\/h3\u003e\n\u003cp\u003eThe 6-inch format is a deliberate design choice. The Stereo Protractor does not replace the SMP-17 or SMP-1M bars in applications requiring wide physical microphone spacing — it handles coincident and near-coincident techniques where both microphones need to be as close together as possible. Used above a point source — a solo instrument, a guitar amplifier, a drum kit in close position — where a full-metre bar would be logistically excessive. Two 5\/8\" threads accept clips or adapters from any microphone manufacturer, and the central stand mount point installs on a standard mic stand without additional couplers.\u003c\/p\u003e\n\u003ch3\u003eTechniques Covered by the Angle Markings\u003c\/h3\u003e\n\u003cp\u003eFour engraved reference points — 0°, 90°, 110°, 180° — cover the key coincident and near-coincident stereo techniques. 90° is XY and Blumlein (with figure-eight microphones). 110° is ORTF — a cardioid pair spaced 17 cm apart with each mic angled 55° off the central axis. 0° and 180° are reference positions for calibration and symmetry verification. The three locking rings included in the kit secure both microphone positions and the stand mount without thread play.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e6\" (approx. 15 cm) length\u003c\/strong\u003e — compact format for coincident and near-coincident techniques in tight miking situations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngraved angle markings:\u003c\/strong\u003e 0°, 90°, 110°, 180° — precise XY, Blumlein, and ORTF setup without measuring tools.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo 5\/8\" microphone threads\u003c\/strong\u003e — accepts clips and adapters from all manufacturers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree locking rings\u003c\/strong\u003e — stable threaded connections without play.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-stand mounting\u003c\/strong\u003e — central mount point for standard microphone stand, no additional couplers needed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Compact stereo protractor bar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 6\" (approx. 15 cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngle markings (engraved):\u003c\/strong\u003e 0°, 90°, 110°, 180°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrophone threads:\u003c\/strong\u003e 2 × 5\/8\" (standard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit contents:\u003c\/strong\u003e bar + 3 × locking ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported stereo techniques:\u003c\/strong\u003e XY (90°), Blumlein (90°, with figure-eight mics), ORTF (110°)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of manufacture:\u003c\/strong\u003e USA (Pasadena, CA)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"AEA","offers":[{"title":"Default Title","offer_id":54069045526865,"sku":"50961","price":24.91,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/AEAStereoBars_ArraysStereoProtractor.jpg?v=1781521239","url":"https:\/\/wrdtunes.com\/fr\/products\/aea-stereo-bars-arrays-stereo-protractor","provider":"Wired Tunes","version":"1.0","type":"link"}
