Q: I’m listening to a file with a certain sampling frequency and my DAC is displaying another frequency value, I’m sure my player is not doing
sampling frequency conversion, nor is the operating system doing it: what does it mean?
A: It’s likely that the DAC the hiFace is connected to uses the channel status information to detect the sampling frequency of the incoming signal. As
the hiFace doesn’t encode these information, the DAC is fooled in detecting the wrong sampling frequency. But if you hear music, this means that the
DAC is correctly converting the right sampling frequency.
Q: Does the hiFace transfer data at 352.8kHz or 384kHz?
A: No, it doesn’t: S/PDIF standard used for hiFace’s output is limited to 192kHz.
Q: Does the hiFace transfer data at 32kHz or 64kHz?
A: No, it doesn’t: the internal crystal oscillators stock doesn’t include these sampling frequencies.
Q: Is it possible to set the hiFace volume by hardware?
A: No it isn’t. In fact, the related control in the Control Panel is greyed out. In case this doesn’t happen, this means that the volume control is
implemented in software by the operating system.
Q: Is hiFace also shipped with BNC out connector?
A: Yes it is.
Q: Is hiFace also shipped with XLR out connector?
A: No, it isn’t.
Q: Is hiFace also shipped with optical out connector?
A: No, it isn’t.
Q: Is hiFace also shipped with I

S output?
A: No it isn’t, whoever needs this connection format may purchase the hiFace Evo, which is provided with it.
Q: Which one’s best: RCA or BNC?
A: BNC is marginally better than RCA. This is due to the fact that using 75 Ohms connectors and BNC-terminated cables it is possible to make
connections which are perfectly matched to S/PDIF standard impedance (which happens to be 75 Ohms). On the other hand, no 75 Ohms male
connectors are available (while one female 75 Ohms connector is availavle, which is not used in the hiFace), so RCA-terminated digital interconnectes
