5.2 Digital

Clocks: Internal, ADAT In, SPDIF In, optional Word Clock In
Low jitter design: < 1 ns in PLL mode, all inputs
Internal clock: 800 ps jitter, random spread spectrum
Jitter suppression of external clocks: about 30 dB (2.4 kHz)
Effective clock jitter influence on AD and DA conversion: near zero
PLL ensures zero dropout, even at more than 100 ns jitter
Additional Bitclock PLL for trouble-free varispeed ADAT operation
Sample frequencies: 32 / 44.1 / 48 / 64 / 88.2 / 96 / 128 / 176,4 / 192 kHz

5.3 Digital Interface

Digital inputs and outputs ground-free transformer coupled
Standard: optical (TOSLINK), phono (SPDIF), optional XLR (AES/EBU)
High-sensitivity input stage phono/XLR: < 0.2 Vss input level
Output voltage phono: 0.8 V, XLR: 3.5 V

5.4 MIDI

1 x MIDI I/O via breakout cable
PCI bus based hi-speed operation
Seperate 128 byte FIFO for input and output
MIDI state machine in hardware for reduced interrupt request load
5.5 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.
MME:
16 bit, 2 byte
20 bit, 3 byte MSB (stereo 6 byte)
20 bit, 4 byte MSB (stereo 8 byte)
24 bit, 3 byte
24 bit, 4 byte MSB (stereo 8 byte)
32 bit, 4 byte
(stereo 4 byte)
(stereo 6 byte)
(stereo 8 byte)
