5. First Usage - Quick Start
Connect the TRS-jacks or the XLR connectors with the analog signal source. Change the input
sensitivity by pressing ANALOG INPUT - LEVEL until the input level is sufficient to avoid noisy
operation. Also try to achieve an optimum input level by adjusting the source itself. Raise the
source’s output level until the yellow –3 LEDs light up.
The analog line inputs of the ADI-2 FS can be used with signals from +4 dBu up to +19 dBu.
The electronic input stage is built in a servo-balanced design which handles monaural and
stereo jacks correctly. When used unbalanced it automatically corrects the gain by 6 dB.
The digital output of the ADI-2 FS can be used as SPDIF, AES/EBU and ADAT optical source.
The button DIG OUT determines the current format:
x
ADAT: The optical TOSLINK output operates in ADAT mode. Included support for S/MUX4
enables sample rates up to 192 kHz. The coaxial output continues to send out SPDIF.
x
PRO: The output signal carries the Channel Status Professional. The physical output level at
the RCA connector is raised, making the signal compatible to AES/EBU. The same signal is
found at the optical output.
x
CON: The output signal carries the Channel Status Consumer. The physical output level at
the RCA connector is lowered. The same signal is found at the optical output.
On the analog playback side (the DA side), simply choose the desired digital input by pressing
DIG IN. The analog output level is set by pressing ANALOG OUTPUT - LEVEL.
The output signal of the DA-converter is also available on the front, in the same quality as on
the rear. The level can be changed in a stepless way using the VOL pot. This output is both
powerful and has a very low output impedance to connect and enjoy even insensitive
headphones.
The button ANALOG INPUT - LEVEL offers a fourth state (DIG). This state activates a digital
pass-through mode with analog monitoring (DA-converter), with the AD-converter not in use.
The level meters show the audio level of the digital input signal.
The button ANALOG OUTPUT - LEVEL offers a fourth state (ANA). This state activates an
analog loop-through mode with digital monitoring (AD-converter), with the DA-converter not in
use.
The button ANALOG OUTPUT - LEVEL also offers the option of switching the VOL knob into
the rear output signal path, for variable adjustment of the rear output level. This is done by
pressing and holding the button for 2 seconds. The active function is visualized by dimmed
OUTPUT LEVEL LEDs.
The ADI-2 FS stores all current settings and automatically activates them when the device is
turned on.
Transferring digital data into a computer is best done using RME's digital audio interfaces.
These interfaces for PCI, PCI Express, USB and Thunderbolt come with drivers for all popular
operating systems, and are highly respected worldwide.
