S input.
This input is not galvanically decoupled, so an external solution or a galvanically isolated
input must be used if galvanic isolation is required.
WARNING: this output CANNOT be directly connected to a North Star Design DAC
such as Model 192 or Extremo! An adapting circuit must be used.
10) RCA S/PDIF output. Connect to DAC or receiver with a 75 Ohms digital cable
terminated with RCA male plugs. This output is galvanically isolated by a pulse
transformer. Gold plated RCA female connector
11) 75 Ohms BNC S/PDIF output. Connect to DAC or receiver with a 75 Ohms digital
cable terminated with BNC male plugs. This output is galvanically isolated by a pulse
transformer. 75 Ohms BNC female connector.
12 AES/EBU output. Connect to DAC or receiver with a 110 Ohms balanced digital cable
terminated with XLR connectors. This output can set to consumer or professional mode by
means of an internal jumper. Instructions about setting the jumper are printed on the PCB.
This output is galvanically isolated by a pulse transformer. XLR male connector.
