5. First Usage – Quick Start
5.1 Connectors and Front Panel
The front of the Multiface II features a MIDI input and output, a stereo headphone output with
volume control, two switches to select the analog reference level, and several status LEDs.
MIDI IN and OUT are 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
Digital 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 8.2 / 16.2,
Clock Modes - Synchronization.
The red
HOST LED lights up when the power supply or the computer is switched on, indicating
the presence of operating voltage. At the same time it works as Error LED, in case the I/O-box
has not been initialised, or the connection to the interface has been interrupted (Error, cable not
connected etc.) – it then flashes. After the firmware had been loaded the LED turns off, thus
signalling a proper operation.
ANALOG LEVEL has two switches with three positions each, to select the reference level of
the eight analog inputs and outputs on the rear.
Phones is a low impedance line output of highest quality, which can produce a sufficient vol-
ume undistorted even when used with headphones.
The volume of the phones output is adjusted with the knob
VOL .
