hiFace Evo
hiFace 進化版
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.
