Connecting the devices
Make sure that the power indicators are off.
Connecting the control surface to the DSP engine

Use Ethernet cables to connect the TO ENGINE OUT/IN jacks of the control surface to the TO CONSOLE OUT/IN jacks of the DSP engine.
Connecting the DSP engines to the I/O rack

Use fiber-optic cables to connect the TWINLANe IN/OUT jacks of the HY card (installed in the DSP engine) to the TWINLANe OUT/IN jacks of the HY card (installed in the I/O rack).
Audio input and output connections

1 Analog input connection Connect a microphone or line-level component to the input jacks of the RY card (RY16-ML-SILK).
- In the default status, there are no patch settings for these input jacks. Before you can use signals at these jacks as the input, you need to make patch settings.
2 Analog output connection Connect a speaker system to the output jacks of the RY card (RY16-DA) to patch the signals on the output channels (MIX, MATRIX, or STEREO), monitor signals and cue signals.
Digital I/O connections
Before you connect digital audio equipment, you need to install an optional card on the I/O rack and the DSP engine. You can also use the AES/EBU connector on the control surface.
