5. Technical Specifications
5.1 Digital
•
Ultra-low jitter S/PDIF: < 1 ns in PLL mode (44.1 kHz, optical in)
•
Ultra-low jitter ADAT: < 2 ns in PLL mode (44.1 kHz, optical in)
•
Input PLL ensures zero dropout, even at more than 40 ns jitter
•
Bitclock PLL for trouble-free varispeed operation in ADAT mode
•
High-sensitivity input stage (< 0.2 Vss input level)
•
Output voltage 0.8V (consumer mode, phono) or 2.3V (professional mode)
•
Sample frequencies: 32 / 44.1 / 48 / 88.2 / 96 kHz and variable (wordclock) supported
5.2 Digital Interface
•
Phono input and output ground-free transformer coupled
•
Connectors: optical (TOSLINK), phono, internal (CD-ROM/Sync in, Sync out)
•
Clocks: ADAT Sync In, word clock I/O
•
Formats: SPDIF (Consumer and Professional), ADAT optical
5.3 Transfer Modes: Resolution / Bits per Sample
ASIO:
•
24 or 32 bit, 4 byte (stereo 8 byte)
This format is compatible with 16-bit and 20-bit. Resolutions below 24-bit are handled by the
audio application. The card works internally with 32-bit data, but audio data transfer is limited to
24-bits. As no additional Channel Status bits are transferred RME’s TMS (Track Marker
Support) is not available. Furthermore, DIGICheck’s
Channel Status Display
is deactivated.
MME:
•
16 bit, 2 byte (stereo 4 byte)
•
20 bit, 3 byte MSB (stereo 6 byte)
•
20 bit, 4 byte MSB (stereo 8 byte)
•
24 bit, 3 byte (stereo 6 byte)
•
24 bit, 4 byte MSB (stereo 8 byte)
•
32 bit, 4 byte (stereo 8 byte)
Channel Interleave operation is not supported. As no additional Channel Status bits are
transferred RME’s TMS (Track Marker Support) is not available. Furthermore, DIGICheck’s
Channel Status Display
is deactivated.
