5. First Usage - Quickstart
5.1 Connectors and Front Panel
The front of the Fireface 800 features an instrument input, microphone inputs and line inputs
with gain pots, a stereo headphone output with volume pot, and several status LEDs.
MIDI/I indicates MIDI data received by the MIDI input.
MIDI/O indicates MIDI data sent to the MIDI output.
The Digital State LEDs (WC, SPDIF,
ADAT, TCO) indicate a valid input signal
separately for each digital input. Additionally,
RME's exclusive SyncCheck indicates if one
of these inputs is locked, but not synchro-
nous to the others, in which case the LED
will flash. See also chapter 11.3/22.3, Clock
Modes - Synchronization.
The red HOST LED lights up when the Fireface 800 has been switched on, thus signalling the
presence of operating voltage. At the same time it operates as error LED, in case the FireWire
connection hasn't been initialised yet, or has been interrupted (error, cable not connected etc.).
Phones is a low impedance line output of highest quality. It provides a sufficient and undis-
torted volume when used with headphones.
The rear panel of the Fireface
800 features eight analog
inputs and outputs, the power
socket, and all digital inputs
and outputs:
ADAT1 I/O (TOSLINK)
ADAT2 I/O (TOSLINK): Can also be used as optical SPDIF input and output, if set up accord-
ingly in the Settings dialog. The Settings dialog is started by clicking on the fire symbol in the
Task Bar's system tray.
SPDIF I/O coaxial (RCA): Fully AES/EBU compatible by transformer-coupling and level adjust-
ment. The Fireface 800 accepts the commonly used digital audio formats, SPDIF as well as
AES/EBU.
Word Clock I/O (BNC): A push switch allows to activate internal termination (75 Ohms). When
termination is activated the yellow LED besides the switch lights up.
IEC receptacle for mains power connection. The specially developed, internal hi-performance
switch mode power supply makes the Fireface operate in the range of 100V to 240V AC. It is
short-circuit-proof, has an integrated line-filter, is fully regulated against voltage fluctuations,
and suppresses mains interference.
