High Sampling Rates with USBPre 2
For many specialized applications, sampling at rates higher than 48 kHz is a requirement.
Some common applications for high sampling rates include:
-
- acoustic test and measurement,
- sound effects recording,
- classical music recording,
- environmental recording.
Stand Alone Mode
When the USBPre 2 is operating in Stand Alone mode (without being connected to a computer), it operates at the sampling rate set by its back panel hardware DIP switches. Available sampling rates include:-
- 16 kHz
- 32 kHz
- 44.1 kHz
- 48 kHz
- 88.2 kHz
- 96 kHz
- 192 kHz
Mac OS 10.5.8+
Mac OS versions 10.5.8 and greater support USB Audio Class 2.0 devices as Core Audio devices. This allows for connections at high sampling rates. USBPre 2 sampling rates supported in Mac OS 10.5.8 and greater include:-
- 8 kHz, 16- or 24-bit
- 16 kHz, 16- or 24-bit
- 24 kHz, 16- or 24-bit
- 32 kHz, 16- or 24-bit
- 44.1 kHz, 16- or 24-bit
- 48 kHz, 16- or 24-bit
- 88.2 kHz, 16- or 24-bit
- 96 kHz, 16- or 24-bit
- 176.4 kHz, 16- or 24-bit
- 192 kHz, 16- or 24-bit
Windows XP, Vista, and 7
Windows does not support USB Audio Class 2, reverting instead to USB Audio Class 1. As a class-compliant device the USBPre 2 has a maximum sampling rate of 48 kHz in Windows. Supported rates include:-
- 8 kHz, 16-bit
- 16 kHz, 16-bit
- 32 kHz, 16-bit
- 44.1 kHz, 16- or 24-bit
- 48 kHz, 16- or 24-bit
