This produces a first-level DC bus from which all further voltages are derived. The circuit also generates a galvanically-isolated power supply voltage for the USB input circuitry.\u003cbr\u003eThe digital section is powered by a bank of 'Super Capacitors' totaling 6.6 Farad (6,600,000uF). Individual low-noise TI LDO Regulators with local LC filtering provide the final low-noise power for all individual digital sections; a total of six individual regulators cover Clock, S\/PDIF Input and the DACs digital section. For the analogue stage (especially the tubes) higher voltages are needed.\u003cbr\u003eThe whole stage effectively operates on a 60V rail offering massive potential dynamic range.\u003c\/p\u003e\n\u003ch1\u003eTechnical Specifications\u003c\/h1\u003e\n\u003cp\u003eSample rates: PCM up to 768kHz\u003cbr\u003eDSD up to 49.152MHz (DSD 1024)\u003cbr\u003eDXD and double-speed DXD (2xDXD)\u003c\/p\u003e\n\u003cp\u003eInputs: USB (required for DSD, DXD and sample rates above 192KHz)\u003cbr\u003eAES3 (XLR single link)\u003cbr\u003eS\/PDIF (coaxial\/optical combo)\u003cbr\u003eBNC multifunction (S\/PDIF in or sync input)\u003c\/p\u003e\n\u003cp\u003eOutputs: Balanced XLR at 4.6V (+15.5dBu HiFi) or 10V (+22dBu Pro)\u003cbr\u003eSingle-Ended RCA at 2.3V (HiFi) or 5V (Pro)\u003cbr\u003eHeadphones 6.3mm \u0026amp; SE 3.5mm Jack at 0.55V\/2.1V\/5V\u003cbr\u003eHeadphones BAL 2.5mm Jack at 1.13V\/4.6V\/10V\u003cbr\u003eHeadphones out 1,500mW RMS X 2 @ 64 ohm, 4,000mW max. 2 X @ 16 Ohm\u003c\/p\u003e\n\u003cp\u003eHeadphone Output Impedance: Single-Ended (S-BAL): \u0026lt; 1Ohm SE\u003cbr\u003eBalanced: \u0026lt;2 Ohm\u003c\/p\u003e\n\u003cp\u003eVolume control: Balanced (6-gang) Alps potentiometer, motorised with IR remote control\u003cbr\u003eXLR\/RCA outputs can be selected as fixed level or adjusted\u003cbr\u003e6.3mm headphone jack is always adjusted\u003c\/p\u003e\n\u003cp\u003eOther Functions: Various digital and analogue filters can be selected for DSD and PCM up to 384KHz\u003c\/p\u003e\n\u003cp\u003ePCM Filters: Bitperfect 44.1 192kHz, always used for 352.8 768kHz\u003cbr\u003eBitperfect + 44.1 96kHz\u003cbr\u003eGibbs Transient Optimised 44.1 384kHz\u003cbr\u003eApodising 44.1 384kHz\u003cbr\u003eTransient Aligned 44.1 384kHz\u003c\/p\u003e\n\u003cp\u003eDSD filters: fixed 3rd order analogue filter @ 80kHz with correction for DSDs -6dB gain\u003c\/p\u003e\n\u003cp\u003eGain (headphone section): user-selectable: 0dB, 9dB and 18dB\u003c\/p\u003e\n\u003cp\u003eDynamic range: 119dBA (solid-state, PCM, -60dBFS)\u003c\/p\u003e\n\u003cp\u003eOutput power (16, balanced\/single-ended): \u0026gt;4000mW \/1\u0026gt;1,500mW\u003c\/p\u003e\n\u003cp\u003eOutput voltage (600, balanced\/single-ended): \u0026gt;11.2V \/ \u0026gt;5.6V\u003c\/p\u003e\n\u003cp\u003eInput voltage (Pro iDSD): DC 9V\/6.7A 18V\/3.35A\u003c\/p\u003e\n\u003cp\u003eInput voltage (iPower+): AC 85 265V, 50\/60Hz\u003c\/p\u003e\n\u003cp\u003ePower consumption: \u0026lt; 22W idle, 50W max.\u003c\/p\u003e\n\u003cp\u003eDimensions: 213 (l) x 220 (w) x 63 (h) mm\u003c\/p\u003e\n\u003cp\u003eWeight: 1980g (4.37 Ibs)\u003c\/p\u003e\n\u003ch3\u003eManufacturer Site\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e\u003ca\u003eiFi Audio\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n","brand":"iFi Audio","offers":[{"title":"Default Title","offer_id":51938262155530,"sku":"IFIAUDIO-4854","price":2749.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/3283\/6618\/files\/ifi-audio-pro-idsd-4.4-18381-p.png?v=1760361905","url":"https:\/\/audioemotion.co.uk\/products\/ifiproidsd","provider":"Audio Emotion Limited","version":"1.0","type":"link"}
