It comes with the latest ARM Cortex-M4 that controls the USB data and also uses a ultra-low jitter clock system. Among the various outputs it has, it includes XLR balanced AES, coaxial RCA/BNC, I2S interface with HDMI socket, and a perfect master clock/word clock output. Apos Audio also found that the SU-2 also supports an external 10 MHz clock input using the common 50 ohm input impedance design. \nWhen the SU-2 is used as an independent master clock, it can output a word clock of 44.1K-384K, or output a master clock of 22.5792 Mhz - 49.152 Mhz. It can be used as a frequency converter when an external 10 Mhz clock input is being used.\nNote: This is the 110 V version. Please contact us if you are looking for the 220 V version.\n\n\n\n\n\n\nSampling Rates\n\nPCM: 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384, 705.6, 768 kHz\nI2S supports all sampling rate, S/PDIF supports up to 384 kHz, DOP 128\nDSD: 2.8 MHz (DSD64), DOP, native; 5.6 MHz (DSD128) DOP, native; 11.2 MHz (DSD256), DOP native; 22.5792 MHz (DSD512 ), DOP, native; 45.1584 MHz (DSD1024), native\nI2S output supports all DSD; S/PDIF, AES/EBU support DSD128 DOP mode\n\nBit Width\n\nUp to 32 bit over I2S output\nUp to 24 bit over S/PDIF\nUSB input socket is a standard USB-B type socket, USB power supply range 4.5V–5.1V\nRCA connector outputs standard S/PDIF signal, electrical level is 550 mV (standard connection load), output impedance of 75 ohms\nPower supply input is AC 115V/230V\n\nSystem Compatibility\n\nWindows XP, Windows 7, Windows 8, Windows 10: 32/64 bit, need installed driver\nNative Mac OS 10.6 and later: Use own driver\nNative Linux with UAC2 compliant kernel: Use own driver\nAndroid OS 4.2 and above: Need support OTG function\n\nI2S Port Using HDMI Output\n\nElectrical level is 3.3V LVDS differential signal\nDSD ON signal, 5V power supply, CPLD has processed the mute signal (no need to process again)\nDSD ON signal can be user def","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-singxer-usb-interface-singxer-su-2-usb-digital-interface-14001218846794.jpg?v=1578619877","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-singxer-usb-interface-singxer-su-2-usb-digital-interface-14001218912330.jpg?v=1740213973","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-singxer-usb-interface-singxer-su-2-usb-digital-interface-14001218879562.jpg?v=1740213973"],"price":470,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:01.583Z"},"share_url":"https://firestarter.network/l/lst_L0SHutIu","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
