AEA's Regular version translates that geometry into hardware: three 1-meter aluminium bars assemble into a 2 m rear span and a 1 m forward arm, proportions close to what Wilkinson used at Kingsway Hall. The result is a system that brings a defined, reproducible method to a technique that has historically relied on educated guesswork and improvised rigging.\u003c\/p\u003e\n\u003ch3\u003eStepless Positioning, No Compromises\u003c\/h3\u003e\n\u003cp\u003eThe SMP-S sliders travel freely along the full length of each bar and lock with a thumb screw at any point — no indexed holes, no 10 cm increments. Shifting the rear pair from 1.5 m to 2 m takes seconds without dismantling the rig, which matters on a live orchestral session where stereo width decisions often come after the first playback, not during load-in. The AEA-CP coupler mounts the entire assembly to a standard 5\/8\" mic stand thread with no adapters required. Four sliders included in the Regular kit cover a standard three-mic T plus one additional position for a spot microphone or an outrigger pair extension.\u003c\/p\u003e\n\u003ch3\u003eBeyond Stereo — Surround and Immersive Arrays\u003c\/h3\u003e\n\u003cp\u003eThe modular format is not limited to three microphones. Additional SMP-S sliders can be ordered separately to expand the array with lateral outriggers or configure a first-order Ambisonic capture rig. Each bar carries a centimetre-engraved scale, so the exact slider positions from a previous session are written down and reproduced to the millimetre at the next one — critical when a film score is tracked across multiple days with matching room image required throughout. The three bars can also be reconfigured as a Mini Tree or Super Tree by substituting bar lengths, making the Regular a long-term investment rather than a single-purpose fixture.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eArray dimensions:\u003c\/strong\u003e 2 m wide (rear arm) × 1 m deep (centre arm) — classic Decca Tree proportions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStepless SMP-S sliders\u003c\/strong\u003e — continuous positioning along the full bar length, thumb-screw lock at any point.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModular design\u003c\/strong\u003e — three 1 m bars reconfigure into Mini Tree, Super Tree, or custom spatial arrays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAEA-CP coupler\u003c\/strong\u003e — direct 5\/8\" mic stand mount, no adapters needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentimetre-engraved scale\u003c\/strong\u003e — session-to-session geometry repeatability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal mic compatibility\u003c\/strong\u003e — accepts any microphone with a standard 5\/8\" clip or adapter.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariant:\u003c\/strong\u003e Decca Tree Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArray dimensions:\u003c\/strong\u003e 2 m (width) × 1 m (depth)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBars included:\u003c\/strong\u003e 3 × SMP-1M (1-meter bar)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSliders included:\u003c\/strong\u003e 4 × SMP-S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracket:\u003c\/strong\u003e 1 × Decca Tree bracket assembly (with angle brackets and hardware)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupler:\u003c\/strong\u003e 1 × AEA-CP (mic stand coupler)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount thread:\u003c\/strong\u003e 5\/8\" standard microphone stand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBar material:\u003c\/strong\u003e Anodised aluminium with engraved centimetre scale\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":54069051294033,"sku":"50959","price":914.79,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/AEAStereoBars_ArraysDeccaTreeRegular.jpg?v=1781521150","url":"https:\/\/wrdtunes.com\/de\/products\/aea-stereo-bars-arrays-decca-tree-regular","provider":"Wired Tunes","version":"1.0","type":"link"}
