Line Level Inputs Analog line level input modules are available in three versions:
• Stereo input with A/B switching, balancing transformer, XLR connectors
• Stereo input with A/B switching, electronically balanced inputs, XLR connectors
• Stereo input with 6-input selector, balancing transformer. On this module the
sources are connected via a 39-pin DIN connector.

Digital Inputs Digital input modules are available either with A/B switching or with a 6-input
selector.
The module with A/B switching supports the AES/EBU (AES3-1992) and S/PDIF
(IEC 958) formats. It is equipped with XLR, Cinch, and TOSLINK connectors.
The 6-input selector supports the AES/EBU (AES3-1992) format and is equipped
with a 39-pin DIN connector for source connection.
All digital inputs are equipped with a sampling frequency converter (SFC).
