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 input accepts audio data from a host (notebook or PC) with
word length up to 24 Bit and fixed sample rate of 44.1, 48 or 96 kHz. 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 cinch 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 for a maximum transfer rate of 12 Mbit/S.
