The design rests on two ESS ES9039Q2M chips mounted in mirrored, isolated circuits, one per channel, driven by a single precision MEMS clock.\u003c\/p\u003e\u003cp\u003eThe internal linear power supply is doubled, with separate regulation for the analogue part and for the digital one, and the USB input is handled by a dedicated ASIC controller. The hardware gain control, in 0.5 dB steps, allows it to be used as a preamplifier connected straight to a power amplifier. NOS Mode bypasses oversampling; the stated THD+N figure is -122.5 dB.\u003c\/p\u003e\u003ch3\u003eTechnical features\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eConverter:\u003c\/strong\u003e 2 ESS Sabre ES9039Q2M in dual mono, 8 digital filters, NOS Mode\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eUSB-B 2.0 input and I2S input on HDMI:\u003c\/strong\u003e PCM at 32 bit \/ 768 kHz and DSD512 at most\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eCoaxial (RCA) and optical (TOSLINK) S\/PDIF inputs:\u003c\/strong\u003e PCM at 24 bit \/ 192 kHz at most\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eAnalogue outputs:\u003c\/strong\u003e balanced XLR at 4 Vrms, unbalanced RCA at 2 Vrms\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePreamplifier mode:\u003c\/strong\u003e gain adjustable from 0 to -99 dB\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eTrigger:\u003c\/strong\u003e one input and one output at 12 V on 3.5 mm jacks\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eControls:\u003c\/strong\u003e 2 rotary encoder knobs with a push button\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePower:\u003c\/strong\u003e external 5 V \/ 2 A power supply and USB cable included\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSize and weight:\u003c\/strong\u003e 27 x 15 x 5 cm, 2.25 kg\u003c\/li\u003e\u003c\/ul\u003e","brand":"Volumio","offers":[{"title":"Default Title","offer_id":58695083589976,"sku":"VOLUMIOPRECISO","price":854.93,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5278\/7645\/files\/volumio-preciso-fronte.jpg?v=1791445491","url":"https:\/\/videosell.eu\/products\/volumio-preciso","provider":"Videosell store","version":"1.0","type":"link"}
