The
front of the Digiface Ravenna features four Gigabit Ethernet ports, 2 BNC sockets for word
or MADI I/O, a state LED, and the headphone output.
The four
network sockets , RJ45 format, support both 100 Mbps and 1 Gbps. The integrated
LEDs show the states connected (yellow) and data traffic (green). The four ports can be used in
switched (4) or redundancy (2) mode (Primary/Secondary).
The
State LED beside the BNC input shows Lock and Sync state for the word or MADI input
signal.
Phones is a low impedance line output. It pro-
vides a sufficient and undistorted volume even
when used with headphones.
In case this output should operate as Line out-
put, an adapter TRS plug to RCA phono plugs,
or TRS plug to TS plugs is required.
The pin assignment follows international
standards. The left channel is connected to the
tip, the right channel to the ring of the TRS
jack/plug.
The
rear of the Digiface Ravenna features the USB 3 port, a status LED, a power supply con-
nector, and a hook to remove strain from the connectors. The LED indicates both power supply
(USB bus power, green), as well as the USB status (yellow: USB 2, blue: USB 3).
USB 3.0 : Standard USB socket for connection to the computer. Please make sure the Digiface
Ravenna can have the full voltage/current delivered from the computer by using hi-quality USB
cables (like the one included). USB extension cables and USB hubs should be avoided. When
connected to USB 2 the channel count is reduced to 64 channels (no MADI).
The Digiface Ravenna uses USB bus power. In case of USB 3 this is usually sufficient to run the
interface. But using all 4 network connections plus headphones can draw more current than the
USB 3 spec suggests (900 mA). The Digiface Ravenna therefore ships with a power supply for
stable operation even at highest load.
