5.2 Operation

Join us for a small 'tour de ADI', starting on the left side with the choice of the currently used
input for the input channels 1/2. This is done via the key AES 1. Options are the XLR socket on
the rear, the 25 pin D-Sub connector, and the optical input IN 2. The LED OPT is red, to signal
that the ADAT input is no longer available. The state of the input signal is displayed by 13 LEDs.
Shown are Lock (per AES and ADAT input, including SyncCheck), Double Speed (64/88.2/96
kHz) and the level of the audio signal.
RME's intelligent clock control (ICC) offers professional means. To start with, the clock source
can be set to word clock, ADAT (IN 1) and AES, where AES lets you select between the inputs
XLR, D-Sub and optical. Lock state and clock synchronicity are being displayed by the state of
the 6 input LEDs (flashing or constantly lit). When the current clock source fails, the last valid
sample rate will be held automatically. This way, the unit could even be 'programmed' to send
any frequency, and used as master further on. At a return of the input signal, the unit falls back
into slave mode seamlessly.
The key DS MODE activates Double Speed mode at the word clock output, at the AES output,
or at both outputs at the same time.
The AES output signal can be set to Consumer or Professional subcode. The first output (chan-
nels 1/2) can optionally be output optically (via TOSLINK) using the second ADAT output.
