About UAD-2 Live Rack system connections
• Do not connect any devices, including a computer, to the UAD‑2 Live Rack 1394b
ports. These ports are for manufacturing purposes only.
• The MADI channels to be processed by UAD‑2 Live Rack are specified in the
Hardware panel of the Settings page within the Live Rack software application.
• When synchronizing to external Word Clock, the first UAD‑2 Live Rack unit (MADI
channels 1 – 16) must receive the Word Clock, then pass the clock to the second
unit and so on (via daisy‑chaining), for up to four units.
• Duplex MADI cables cannot be used with multi‑unit configurations.
• All Live Rack MIDI control commands are received via the Audio MIDI Setup
application in macOS. Refer to the MIDI control device documentation for setup.
• When operating the UAD‑2 Live Rack hardware, the unit must be placed or
mounted with the vent holes facing up.
Single Unit Wiring
The diagram below illustrates connections for one UAD‑2 Live Rack unit for up to 16
MADI channels of UAD plug‑in processing.
Cables Required (not included):
• One Thunderbolt 3 cable between UAD‑2 Live Rack and the host computer for
software control
• Two MADI optical cables (or a single duplex cable) between UAD‑2 Live Rack and
the MADI device for digital audio send/return
