6. First Usage - Quick Start

Connect the TRS-jacks or the XLR connectors with the analog signal source. Change the input
sensitivity by pressing INPUT - LEVEL until the input level is sufficient to avoid noisy operation.
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 can be used with +4 dBu and -10 dBV signals. The elec-
tronic 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 can be used as SPDIF, AES/EBU and ADAT optical source. The
button OUTPUT sets the format:
• ADAT: The optical TOSLINK output operates in ADAT mode. Included support for Sample
Split (S/MUX) enables sample rates up to 96 kHz.
• 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-3 and AES/EBU. The
same signal is found at the optical output.
• 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), you just have to choose the desired digital input by
pressing DIGITAL - INPUT. A coarse correction of the analog output level can be done by
pressing OUTPUT LEVEL.
The output signal of the DA-converter is also available on the front, in the same quality as on
the back. The level can be changed in a stepless way using the VOL pot. The very low imped-
ance type output even allows for a connection of headphones.
The button INPUT LEVEL offers a fourth state (LEDs off), digital pass-through mode with ana-
log monitoring (DA-converter). In this mode the AD-converter is not used. The level meters
show the audio level of the digital input signal.
The ADI-2 stores all current settings and automatically activates them when the device is turned
on.
Transferring digital data into a PCI bus equipped computer is best done using RME's digital
interface cards of the Hammerfall
lar operating systems. They have a world wide reputation as ultimate solution for master and
multitrack tasks.
