THE DIGITAL INPUTS

Four digital inputs are found on the unit's rear panel. They are denoted
according to their electrical properties: balanced, coaxial (unbalanced),
optical and USB.
You won't find terms like AES, S/P-DIF, professional or consumer here,
since it doesn't matter at all which signal type is applied to a dedicated
input.
The electrical inputs (Bal and Coax) accept PCM-encoded digital audio data
with a word length of 16 ... 24 bit and 28 ... 210 kHz sample rate. So does
the optical input.
The USB- 24/192 circuitry uses the X-Mos chip set. It accepts 32, 44.1, 48,
88.2, 96, 176.4 und 192 kHz sample rate. In order to avoid any interference
caused from the host, the USB input is fully insulated, with the signal
coupled via transformer.
- The balanced input is equipped with an XLR socket according to AES 3-
1992, transformer-balanced, at 110 ohms input impedance and 200mV
sensitivity at Tnom/2.
- The coaxial input is fitted with a RCA socket according to IEC 958 and
AES-3-id resp., unbalanced at 75 ohms input impedance and 200 mV
sensitivity at Tnom/2
- The optical input provides a TOS-Link connector according to EIAJ RC-
5720.
- The USB terminal is specified as audio interface according to USB 1.1 /
2.0 standard. The USB 24/192 version needs a proprietary driver for
proper operation which can be downloaded here:
