No. Ref. No. Name 1 S4 2 x 4/1 x 8 Function 2 x 4: Distributes the AES/EBU signal input to the AES/EBU IN1 and AES/EBU IN2 connectors to four and outputs it. 1 x 8: Distributes the AES/EBU signal input to the AES/EBU IN1 connector to eight and outputs it. Re-clocks the AES/EBU signal input to the AES/EBU IN1 connector and outputs it. OFF: Outputs the AES/EBU signal input to the AES/EBU IN1 connector without re-clocking it. ON: Re-clocks the AES/EBU signal input to the AES/EBU IN2 connector and outputs it. OFF: Outputs the AES/EBU signal input to the AES/EBU IN2 connector without re-clocking it. ON:

Indicators
No. Ref. No. Name 4 D103 CH1 AES/EBU Function Lights (green): When a normal signal is input to the AES/EBU IN1 connector. Lights (red): When the signal input to the AES/EBU IN1 connector is abnormal (including the case where there is no signal). Lights (green): When a normal signal is input to the AES/EBU IN2 connector with S4 set to 2 x 4 mode. Lights (red): When the signal input to the AES/EBU IN2 connector is abnormal with S4 set to 2 x 4 mode (including the case where there is no signal). Goes off: When S4 is set to 1 x 8 mode. Lights (green): When an AES/EBU signal with a sampling frequency of 48 kHz is input to the AES/EBU IN1 connector. Lights (green): When an AES/EBU signal with a sampling frequency of 44.1 kHz is input to the AES/EBU IN1 connector. Lights (green): When an AES/EBU signal with a sampling frequency of 32 kHz is input to the AES/EBU IN1 connector. Lights (green): When an AES/EBU signal with a sampling frequency of 48 kHz is input to the AES/EBU IN2 connector. Lights (green): When an AES/EBU signal with a sampling frequency of 44.1 kHz is input to the AES/EBU IN2 connector. Lights (green): When an AES/EBU signal with a sampling frequency of 32 kHz is input to the AES/EBU IN2 connector.
