With YULONG’s seventh-generation JIC (Jitter and Interfacing Control) processor at its core, the DP1 handles high-resolution formats, syncs cleanly with external clocks, and integrates smoothly into systems with coaxial, AES, optical, and I2S outputs. Whether you're running a multi-device audio chain or streaming lossless from your server, the DP1 gives you clarity, precision, and tons of flexibility.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eBuilt around the JIC processor\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe DP1 uses YULONG’s 7th-generation JIC module, a proprietary FPGA-based engine that handles everything from clock synchronization to USB interfacing. This isn't an off-the-shelf chip—it's a deeply integrated, purpose-built processor developed in-house over years of iteration and refinement. The result is stable, low-jitter transmission with minimal digital noise. \u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eDual-core CPU with audio-optimized Linux\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eInstead of relying on a general-purpose OS and driver stack, the DP1 runs a stripped-down Linux kernel tailored for digital audio. The dual-core processor communicates directly with the FPGA, handling network streaming, USB transfer, clock PLL, and SPDIF encoding in one tight loop. Everything’s tuned for audio—right down to the memory layout.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eNetwork streaming done right\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eDLNA, AirPlay2, Roon Bridge, Squeezelite, Spotify, LMS, HQPlayer NAA, Daphile—it’s all available on the DP1. Stream from your preferred server or app without conversion losses or weird workarounds. Plus, it uses I2S in slave mode with dual Accusilicon AS338 oscillators, keeping the clock local and accurate. This gives you a cleaner, more coherent stream than standard USB audio.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eFaster, cleaner USB\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eYULONG’s FPGA+ULPI USB interface is hardware-based—no messy driver layers, no interrupt overhead. It supports PCM1536kHz and DSD1024 natively and avoids the timing drift and conversion artifacts that can plague software-driven USB inputs.\u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eFlexible digital output options\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe DP1 offers coaxial, optical, AES, and I2S outputs—each filtered and clocked for minimum noise and maximum stability. Coax and AES outputs support PCM384 and DoP128, while I2S can hit up to PCM1536 and DSD1024. \u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eHigh-isolation power supply\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eA 25W linear power supply provides interference-free power. Each major subsystem—CPU, network port, USB, clock, PLL, driver stage—has its own low-noise regulator. The analog design minimizes interference between sections, giving you a quieter background and a more dynamic signal.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eCustom display and interface\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eThe IPS screen shows real-time signal spectrums and vintage-style VU meters, adding a touch of analog flair to this digital powerhouse. The interface is simple—just one knob controls all settings. You can customize the display, turn it off automatically, or leave it on to admire the visuals.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eBuilt to last and made to look good\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eMachined from a single block of aluminum, the DP1's enclosure is sturdy, vibration-resistant, and seamless. Claw-shaped metal feet isolate it from external vibrations, while the global voltage selector makes it easy to use in different regions without needing a step-down converter.\u003c\/p\u003e\n \u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eYULONG’s 7th-gen JIC digital signal processing module\u003c\/li\u003e\n \u003cli\u003eDual-core CPU with FPGA-optimized power and streamlined Linux OS\u003c\/li\u003e\n \u003cli\u003eDual Accusilicon AS338 low-noise oscillators\u003c\/li\u003e\n \u003cli\u003eStreaming support: AirPlay2, DLNA, Squeezelite, Roon Bridge, HQ NAA, Daphile, LMS, Spotify\u003c\/li\u003e\n \u003cli\u003eI2S slave mode with PLL clock sync\u003c\/li\u003e\n \u003cli\u003eFPGA + ULPI hardware USB interface\u003c\/li\u003e\n \u003cli\u003eUSB input supports PCM1536kHz and DSD1024\u003c\/li\u003e\n \u003cli\u003eCoaxial and AES outputs support PCM384 and DoP128\u003c\/li\u003e\n \u003cli\u003eOptical output supports up to PCM192 and DoP64\u003c\/li\u003e\n \u003cli\u003eI2S output supports PCM1536 and DSD1024\u003c\/li\u003e\n \u003cli\u003eWord clock input and output\u003c\/li\u003e\n \u003cli\u003e25W linear power supply with low-noise regulators\u003c\/li\u003e\n \u003cli\u003eIPS LCD with dynamic spectrum and VU meter displays\u003c\/li\u003e\n \u003cli\u003eOne-knob control and customizable interface\u003c\/li\u003e\n \u003cli\u003eSeamless aluminum chassis with anti-vibration feet\u003c\/li\u003e\n \u003cli\u003eExternal global voltage switch\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003e\n \u003cstrong\u003eSpecs\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eInputs:\n \u003cul\u003e\n \u003cli\u003eNetwork\u003c\/li\u003e\n \u003cli\u003eUSB\u003c\/li\u003e\n \u003cli\u003eWord Clock In\u003c\/li\u003e\n \u003cli\u003eOutputs:\u003c\/li\u003e\n \u003cli\u003eI2S (configurable)\u003c\/li\u003e\n \u003cli\u003eAES\u003c\/li\u003e\n \u003cli\u003eCoaxial\u003c\/li\u003e\n \u003cli\u003eOptical\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/li\u003e\n \u003cli\u003eWord Clock Out\u003c\/li\u003e\n \u003cli\u003eSupported formats:\n \u003cul\u003e\n \u003cli\u003eUSB\/Network PCM: up to 1536kHz\u003c\/li\u003e\n \u003cli\u003eUSB\/Network DSD: Native DSD64–DSD1024\u003c\/li\u003e\n \u003cli\u003eCoaxial\/AES: up to PCM384kHz \/ DoP128\u003c\/li\u003e\n \u003cli\u003eOptical: up to PCM192kHz \/ DoP64\u003c\/li\u003e\n \u003cli\u003eI2S: up to PCM1536kHz \/ Native DSD1024\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/li\u003e\n \u003cli\u003eClock:\n \u003cul\u003e\n \u003cli\u003eDual Accusilicon AS338 oscillators\u003c\/li\u003e\n \u003cli\u003eWord clock input\/output: 44.1kHz–768kHz\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/li\u003e\n \u003cli\u003eDisplay:\n \u003cul\u003e\n \u003cli\u003eIPS LCD with dynamic spectrum and VU meters\u003c\/li\u003e\n \u003cli\u003eAuto-off feature\u003c\/li\u003e\n \u003cli\u003eCustomizable UI\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/li\u003e\n \u003cli\u003ePower:\n \u003cul\u003e\n \u003cli\u003e25W linear power supply\u003c\/li\u003e\n \u003cli\u003eLow-noise regulators for each subsystem\u003c\/li\u003e\n \u003cli\u003eExternal voltage selector\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/li\u003e\n \u003cli\u003eMeasurements:\n \u003cul\u003e\n \u003cli\u003eTHD+N: 0.000008%\u003c\/li\u003e\n \u003cli\u003eDynamic range: 140dB\u003c\/li\u003e\n \u003cli\u003ePower consumption: \u0026lt;20W\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/li\u003e\n \u003cli\u003eDimensions: 9.8in x 8.3in x 2.4in (248mm x 210mm x 60mm)\u003c\/li\u003e\n \u003cli\u003eWeight: 5.5lbs (2.5kg)\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003e\u003cstrong\u003eWhat’s included\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eYULONG DP1 Network \/ USB Digital Interface\u003c\/li\u003e\n \u003cli\u003ePower cord\u003c\/li\u003e\n \u003cli\u003eRemote control\u003c\/li\u003e\n \u003cli\u003eUser manual\u003c\/li\u003e\n \u003c\/ul\u003e","brand":"Yulong","offers":[{"title":"Black","offer_id":46866225529007,"sku":"APS-1016-1","price":939.0,"currency_code":"USD","in_stock":true},{"title":"Silver","offer_id":46866225561775,"sku":"APS-1016-2","price":939.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/apos-audio-xduoo-dac-digital-to-analog-converter-yulong-daart-dp1-network-usb-digital-interface-1154368333.jpg?v=1777716404","url":"https:\/\/freshized.com\/products\/yulong-daart-dp1-network-usb-digital-interface","provider":"Freshized","version":"1.0","type":"link"}
