Singxer USB Digital Interface Femtosecond Clock Interface PCM768K DSD1024 SU-2

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ SU-2 uses a proprietary ultra-low jitter clock system. (ACCUSILICON's AS-318B series achieves ultra-low jitter at femtosecond level). A large-capacity FPGA is used as the digital audio data processing core and has a standard USB2.0 input interface. Rich output interfaces including XLR balanced output AES, coaxial RCA and BNC, I2S interface with HDMI socket output, complete master clock and word clock (WCLK) outputs SU-2 supports external 10Mhz clock input, common 50 ohm input impedance design. When used as an independent master clock, it can output 44.1K-384K word clock or 22.5792Mhz-49.152Mhz master clock. (If not connected to USB, it will be used as master clock device by default) When using an external 10Mhz clock input, it can also be used as a frequency converter; supports 10Mhz to 44.1K-384K word clock, or also supports 22.5792Mhz-49.152Mhz master clock output. Full isolation technology (ground isolation) with 150Mbps full isolation chip can completely isolate interference from your PC. Source synchronous technology and FPGA shaping technology reshape the I2S signal after isolation, thus eliminating the additional jitter introduced by the isolation chip. Technical indicators: Sampling rates supported by each output interface: PCM: 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz, 192KHz, 352.8KHz, 384KHz, 705.6KHz, 768KHz [If I2S output supports all sampling rates, S/PDIF supports up to 384KHz, DOP128] 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 [All I2S outputs support all DSD formats, S/PDIF and AES/EBU support DSD128 DOP mode] Bit width: up to 32 bits with I2S output 24 bit on S/PDIF Electrical standards for each interface: 1. The USB input socket is a standard USB-B female socket, and the USB power supply range is 4.5V-5.1V. 2. The RCA interface outputs a standard S/PDIF signal with a level of 550mV (connected to a standard load) and an output impedance of 75 ohms. 3.The power input is 115V/230V AC, and an imported transformer inside is used for power supply. System compatibility: 1, Windows 7, Windows 8, Windows 10, 32/64 bit, special driver installation required 2, Native MacOS 10.6 or later uses system-specific drivers 3. Native Linux with UAC2 compliant kernel using system-proprietary drivers (tested on Ubuntu and Daphile systems based on INTEL X86 platform) 4, Android OS 4.2 or above, the device must support OTG function Generally, Android 9.0 or above system is supported by default. Recommended for use with special players below 9.0. I2S interface uses HDMI socket output. 1. 3.3V LVDS differential signal. 2. DSD ON signal, 5V power supply (small current), CPLD are processed within the MUTE signal, and there is no need to output the MUTE signal. 3. The DSD ON signal can be defined independently, and the DSD ON signal can be output to pins 13, 14, 15, and 16 of the socket arbitrarily. I2S and clock output configuration: 1. Switches 1-4 correspond to PIN13-16 pins of HDMI socket. Pulling to ON position means HDMI PIN has DSD_ON function. 2. Switches 5 and 6 are modes to configure the clock output. When switch 5 is off, the clock outputs MCLK, when on, the clock outputs WCK. Switch 6 sets the MCLK frequency. This is 22.5792M/24.576M when off and 45.1584M/49.152M when on. Switch 6 configuration is valid for CLK OUT, RJ45-I2S, and HDMI-I2S. 3.Switch 7 can set left and right channels individually in DSD mode for I2S signal. 4. Switch 8 can set the BCLK line sequence with I2S signal; when OFF, PIN4 is BCLK+ and PIN6 is BCLK-. 5. Switch 9 can set the line sequence of LRCLK with I2S signal; when OFF, PIN7 is LRCLK+ and PIN9 is LRCLK-. 6. Switch 10 can set the line sequence of DATA with I2S signal; when OFF, PIN1 is DATA+ and PIN3 is DATA-. Case size and packaging: Chassis length, width, height: 234MM * 170MM * 46MM, excluding protruding parts Standalone weight: 1.8KG.
