Each of the four channels features API's signature transformer-balanced input, 48V phantom power, polarity reverse, pad, and high-pass filter, delivering the punchy, clear, and musical preamp character that engineers have relied on for decades. The 3124+ is equally at home tracking drums, acoustic instruments, brass, or any source that benefits from a fast, authoritative front end.\u003c\/p\u003e\u003cp\u003eThis example is in excellent condition and fully operational.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Four-channel microphone preamplifier\u003c\/li\u003e\n\u003cli\u003eManufacturer: API (Automated Processes Inc.)\u003c\/li\u003e\n\u003cli\u003eModel: 3124+\u003c\/li\u003e\n\u003cli\u003eChannels: 4\u003c\/li\u003e\n\u003cli\u003eFeatures: 48V phantom power, polarity reverse, -20dB pad, high-pass filter per channel\u003c\/li\u003e\n\u003cli\u003eOp-amp: API 2520 discrete\u003c\/li\u003e\n\u003cli\u003eCondition: Excellent, fully functional\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eContact us with any questions.\u003c\/p\u003e","brand":"API","offers":[{"title":"Default Title","offer_id":67756738150706,"sku":null,"price":2100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/6892\/6514\/files\/Photo_Apr_22_2026_11_23_09_AM.jpg?v=1790557455","url":"https:\/\/sphererecordingconsoles.com\/products\/api-3124-four-channel-microphone-preamplifier","provider":"Sphere Recording Consoles","version":"1.0","type":"link"}
