Figure 5-3 AES/EBU Pinout
The first two pairs (four channels) of AES/EBU inputs have a lift switch so that you
can remove the termination for cascading the same AES signal to other units. When
cascading AES signals, ensure that the last device on the chain remains terminated.
5.2.3 MP I/O
A high-density connector for future interfacing to external control devices, MP I/O
provides a high-speed RS422 standard serial interface and MIDI input, throughput
and output.
5.2.4 Word Clock
A female BNC is used for interfacing to standard professional external word clock
signals for synchronizing the Dolby Lake Processor to other audio devices, such as
professional digital audio consoles. A termination switch is provided to lift the
termination for allowing a cascade of the word clock to multiple devices using a
T-node connector.
