clock in,I2S out規格與支援度完整的usb輸出入介面 365.00 美元
USB-to-S/PDIF interface, based on the same technology as hiFace, but with many improvements. Hosted in a stylish brushed aluminum case (105 x 100 x 46mm), with B-type female USB connector.
Main features
input for external supply (7 to 11VDC)
input for external Master Clock (BNC with transformer)
2 x S/PDIF outputs (RCA and 75 Ohms BNC)
AES/EBU output with XLR connector and settable format (consumer and professional) by an internal jumper
Toslink output
ST output
direct I2S output with 3.3V interface.
Some customers complained because of the lack of sampling frequency encoding in the S/PDIF stream of the present hiFace. The new model will have this fixed, for full compliance with the standard.
All outputs (except I2S) are transformer-decoupled to avoid ground noise and EMI interference. Three LED's indicate power, data stream in input and external clock presence.
