Discrete Class A FET input stages feed a switchable signal path: engage the 12AT7 vacuum tube for warm, harmonically rich character, or select the clean solid-state voicing for transparent, extended response out to 120 kHz. It is two distinct preamps in one box — and at this price point, one of the best-value front ends in project and professional studios alike.\u003c\/p\u003e\n\u003cp\u003eEach channel accepts XLR microphone or 1\/4\" instrument sources, with variable input impedance from 600 ohms to 80 kilohms that dramatically changes how dynamic and ribbon mics load and bloom. A Character switch adds frequency enhancement, while low-cut filters, phase invert and +48V phantom power cover every session need. Classic analog VU meters keep levels in view, and balanced XLR and 1\/4\" outputs with selectable +4 dBu \/ -10 dBV operation interface with any console or interface.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTwo channels of discrete Class A FET preamplification, up to 70 dB gain\u003c\/li\u003e\n\u003cli\u003eVoice switch: warm 12AT7 tube or clean solid-state signal path per channel\u003c\/li\u003e\n\u003cli\u003eVariable input impedance (600 ohms – 80 kilohms) for mic tone shaping\u003c\/li\u003e\n\u003cli\u003eCharacter switch, low-cut filter, phase invert, +48V phantom power\u003c\/li\u003e\n\u003cli\u003eAnalog VU meters; balanced XLR and 1\/4\" outputs; +4 dBu \/ -10 dBV operation\u003c\/li\u003e\n\u003cli\u003eUniversal internal power supply (100–240V)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaximum gain: 70 dB\u003c\/li\u003e\n\u003cli\u003eFrequency response: 15 Hz – 48 kHz (tube), 15 Hz – 120 kHz (solid state)\u003c\/li\u003e\n\u003cli\u003eTHD: \u0026lt;0.005% typical; EIN: -128 dBu (A-weighted)\u003c\/li\u003e\n\u003cli\u003eMax output: +27 dBu balanced\u003c\/li\u003e\n\u003cli\u003eDimensions: 3.5\" x 19\" x 8.75\" (2U rack); Weight: 10.5 lb\u003c\/li\u003e\n\u003cli\u003eUPC: 840402050988\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eART Pro MPA III preamplifier\u003c\/li\u003e\n\u003cli\u003ePower cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ART","offers":[{"title":"Default Title","offer_id":46684321448133,"sku":"ARTP-PROMPAIII","price":559.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/ART-PROMPAIII-TubePreamp2C.jpg?v=1786396339","url":"https:\/\/avlgear.com\/products\/art-pro-mpa-iii-2-channel-multi-voice-tube-microphone-preamp","provider":"AVLGEAR","version":"1.0","type":"link"}
