It was designed for the desktop, but it is just as much at home in a recording studio or at the heart of a hi-fi system.\u003c\/p\u003e\n\u003ch2\u003eA 5 W headphone amp up front\u003c\/h2\u003e\n\u003cp\u003eThe headphone stage delivers up to 5 W (5.3 W maximum, as stated by miniDSP) with THD+N of -117 dB, or 0.00014%. Two outputs sit on the front panel: a balanced 4-pin XLR output and an unbalanced 6.35 mm (1\/4\") jack.\u003c\/p\u003e\n\u003ch2\u003eDSP processing for headphones and speakers alike\u003c\/h2\u003e\n\u003cp\u003eProcessing runs on an Analog Devices SHARC DSP clocked at 400 MHz, with 32-bit floating point. You get the familiar miniDSP toolset: parametric EQ, IIR and FIR filters, crossovers, advanced biquads and delay on every output channel.\u003c\/p\u003e\n\u003cp\u003eOn headphones, this engine handles headphone EQ, to correct or fine-tune the sound of your model. With speakers, it lets you integrate a subwoofer or build an active crossover. Everything is set up in the miniDSP Device Console software.\u003c\/p\u003e\n\u003ch2\u003eConnectivity built for desktop, studio and hi-fi\u003c\/h2\u003e\n\u003cp\u003eThe digital inputs match the other Flex units: USB Audio, handled by a multi-core XMOS processor, coaxial SPDIF on RCA, optical, and Bluetooth with LDAC, aptX HD, aptX, AAC and SBC codecs. A pair of balanced stereo analog inputs on TRS jacks rounds things off.\u003c\/p\u003e\n\u003cp\u003eAround the back, four balanced line outputs on TRS jacks feed active speakers and one or two subwoofers in a 2.0, 2.1 or 2.2 setup. Outputs 3 and 4 share the headphone signal. The OLED display, volume knob, infrared remote and 3.5 mm trigger in\/out make day-to-day use straightforward.\u003c\/p\u003e\n\u003ch2\u003eOptional Dirac Live for room correction\u003c\/h2\u003e\n\u003cp\u003eThe miniDSP Flex HPA supports full-range stereo Dirac Live 3.x, from 20 Hz to 20 kHz. This software upgrade is optional and paid: it is not included with the unit. It corrects the effect of the room on your speakers and requires a UMIK-1 or UMIK-2 measurement microphone, not included, such as the \u003ca href=\"\/en\/products\/minidsp-umik-1\"\u003eminiDSP UMIK-1\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailable to order\u003c\/strong\u003e: miniDSP expects first shipments at the end of November 2026.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: stereo DSP processor with DAC and headphone amp (Flex series)\u003c\/li\u003e\n\u003cli\u003eHeadphone power: up to 5 W (5.3 W maximum stated)\u003c\/li\u003e\n\u003cli\u003eHeadphone amp THD+N: -117 dB (0.00014%)\u003c\/li\u003e\n\u003cli\u003eFront headphone outputs: balanced 4-pin XLR, unbalanced 6.35 mm jack\u003c\/li\u003e\n\u003cli\u003eDAC: SNR 126 dB(A), THD+N -120 dB (0.0001%)\u003c\/li\u003e\n\u003cli\u003eDigital inputs: USB Audio, coaxial SPDIF (RCA), optical, Bluetooth (LDAC, aptX HD, aptX, AAC, SBC)\u003c\/li\u003e\n\u003cli\u003eAnalog inputs: 1 balanced stereo pair on TRS jacks\u003c\/li\u003e\n\u003cli\u003eLine outputs: 4 balanced channels on TRS jacks (2.0, 2.1 or 2.2), outputs 3 and 4 shared with the headphone output\u003c\/li\u003e\n\u003cli\u003eDSP: Analog Devices SHARC 400 MHz, 32-bit floating point\u003c\/li\u003e\n\u003cli\u003eUSB processor: multi-core XMOS\u003c\/li\u003e\n\u003cli\u003eProcessing: parametric EQ, IIR and FIR filters, crossovers, advanced biquads, per-output-channel delay\u003c\/li\u003e\n\u003cli\u003eDirac Live 3.x full-range stereo (20 Hz to 20 kHz): optional paid upgrade, not included\u003c\/li\u003e\n\u003cli\u003eInterface: OLED display, volume knob, infrared remote\u003c\/li\u003e\n\u003cli\u003eTrigger: in\/out on 3.5 mm jack\u003c\/li\u003e\n\u003cli\u003eConfiguration software: miniDSP Device Console\u003c\/li\u003e\n\u003cli\u003eIn the box: Flex HPA, IR remote, universal 12 V power supply, USB cable\u003c\/li\u003e\n\u003cli\u003eMeasurement microphone (UMIK-1 or UMIK-2) not included, required for Dirac Live\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"miniDSP","offers":[{"title":"Default Title","offer_id":55038544216387,"sku":"MINIDSPFLEXHPA","price":1239.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/5615\/5715\/files\/Flex_20HPA_20-_20perspective.jpg?v=1794397928","url":"https:\/\/coolkidsaudio.com\/en\/products\/minidsp-flex-hpa","provider":"Cool Kids Audio","version":"1.0","type":"link"}
