9. Operation and Usage

9.1 Connectors

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 Clock Input State LEDs (WC, SPDIF, ADAT, TCO) indicate separately for each digital

input a valid input signal. Additionally, RME's exclusive SyncCheck indicates if one of these

inputs is locked, but not synchronous to the others, in which case the LED will flash. See also

chapter 8.3, 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, which can produce a sufficient undis-

torted volume also when used with headphones.

The rear panel of the Fireface 800 features 8 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.

SPDIF I/O coaxial (RCA): Fully AES/EBU compatible by transformer-coupling and level ad-

justment.

The SPDIF input is selected via the Settings dialog, started by clicking on the fire symbol in the

Task Bar's system tray. The Fireface 800 accepts the commonly used digital audio formats,

SPDIF as well as AES/EBU.

Wordclock I/O (BNC): A push switch allows to activate internal termination (75 Ohms).

IEC receptable for 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 abso-

lutely short-circuit-proof, has an integrated line-filter, is fully regulated against voltage fluctua-

tions, and suppresses mains interference.
