5.3 Notes on Power Supply

The CardBus card delivers no power to the Multiface. Therefore a hi-tech switching power
supply is included.
The PCI card operates as power supply for the attached Multiface via the FireWire cable.
An external power supply is not required.
The Multiface draws a high startup current of more than 2.5 A during initialisation. Current at 12
Volt operating voltage: unloaded 500 mA (6 Watts), loaded 760 mA (9 Watts). Supply voltage
range DC 8 V – 28 V, AC 8 V – 20 V.
6. First Usage – Quick Start

6.1 Connectors and Front Panel

The front of the Multiface features a MIDI input and output, a stereo headphone output and
several status LEDs.
MIDI IN and OUT represent the MIDI input and output, realized as 5-pin DIN jacks.
The LEDs MIDI IN and OUT indicate sent or received data for the MIDI ports.
The INPUT STATE LEDs (WC, SPDIF, ADAT) 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 synchronous to the others, in which case the LED will flash. See also chapter
11.2 / 20.2, Clock Modes - Synchronization.
The red HOST LED lights up when the power supply or the computer is switched on, thus sig-
nalling the presence of operating voltage. At the same time it operates as Error LED, in case
the I/O-box wasn't initialised, or the connection to the interface has been interrupted (Error,
cable not connected etc.). It flashes then. After the firmware had been loaded the LED turns
off, signalling a proper operation.
The rear panel of the Multiface has eight analog inputs and outputs, the power socket AUX
(only necessary with CardBus operation), ADAT Sync, Word Clock I/O and both digital inputs
and outputs ADAT and SPDIF.
ADAT 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 hammer symbol in
the Task Bar's system tray.
SPDIF I/O coaxial (RCA): Fully AES/EBU compatible by transformer-coupling and level ad-
justment. The Multiface accepts the commonly used digital audio formats, SPDIF as well as
AES/EBU.
Word Clock I/O (BNC). The word clock input is not terminated.
ADAT Sync In for connection to ADAT Sync of an ADAT recorder. Allows for sample-accurate
synchronization with ASIO 2.0.
