The front of the Digiface USB features the USB connector, five status LEDs and the head-
phone output.
The USB power LED indicates sufficient power supply (USB bus power).
Sync LEDs 1 to 4 show the current status of all optical inputs. With no input signal they stay
dark. With recognized but not synchronous ADAT or SPDIF signal they flash. With a valid and
synchronous input signal they stay constantly lit.
USB 2.0: Standard USB socket for connection to the computer. Please make sure the Digiface
USB can have the full voltage/current delivered from the computer by using hi-quality USB ca-
bles (like the one included), no USB extension cables and no USB hubs. When connected to
USB 3 only the USB 2 protocol will be used.

output of highest quality. It provides a

RCA phono plugs, or TRS plug to TS

ternational standards. The left
channel is connected to the tip, the

These are compatible with ADAT optical and SPDIF optical.
