4. The Hardware
9 MADI 1 to 4 (via SFP)
The four MADI ports can be used to connect multi-channel digital audio to the device (up to 64 bi-directional
MADI channels per port). Ports 1&2 and 3&4 can be dual-redundant (defined by the ON-AIR Designer).
10 WCLK IN & OUT
WCLK IN can be used to connect an external wordclock sync reference. Other reference options are PTP,
MADI or Internal.
WCLK OUT always provides an output of the current system reference.
11 GPIO
This connector provides 8 x GPI (optocouplers) and 8 x GPO (silent and self-healing relays) for local signaling
and switched functions.
For Power Core Edge or Super Audio Node, you must purchase the GPIO add-on license to activate these
signals.
