USB-2-SPDIF is a high-end asynchronous USB to S/PDIF converter, it supports up to 192kHz and has coax and optical outputs. It is based on the XMOS chip, enhanced by ultra low jitter clocks and our SuperTeddyReg power supply technology. The USB-2-SPDIF is built as stand alone box, no external power supply is required. The Coax output uses a WBT NextGen socket. A true 75ohm socket, even at high frequencies. Input: USB Output: Coax, Optical. Voltage: 110-120V or 220-240V Sample Rates: 44.1kHz, 48kHz, 88.2kHz,96kHz,192kHz.
