RME ADI-2 Overview

The ADI-2 from RME is a compact and flexible two-channel analog-to-digital and digital-to-analog converter, providing conversion to and from S/PDIF, AES/EBU and ADAT. Balanced inputs and outputs and RME's proprietary "SteadyClock" internal clocking help maintain signal quality throughout the unit.

A three-stage hardware input and output level control allows for accurately calibrating signal levels in the analog domain. The transformer-balanced coaxial SPDIF I/O has switchable "Channel Status" to make it fully AES/EBU compatible. The optical TOSLink I/Os can handle up to 192kHz and also serve as ADAT I/O with up to 96kHz sample rates.

The ADI-2 comes with an external power supply. The unit's additional internal switching power supply has been specially designed and optimized for audio applications, and accepts any voltage from 7 to 30V, be it AC or DC, and even runs on regular batteries or rechargeable batteries.

Just to confirm. XLR outputs on the back are marked as &quot;line&quot;, it means volume knob on the front panel will not change volume on these outputs like in case of Benchmark DAC for example. Is it correct?
Asked by: Igor
Both the RCA and XLR outs are adjustable up to +13dBu or +19 dBu. You're able to control the volume like a pre-amp using the RME's volume knob or you can lock the output at a pre-set output level to act as a line out. So you can do both for whichever is more beneficial to your setup. I personally have the RCA outs locked at (-6dB) on +13dBu (max is +6 dB). There's just too much power output at max, my stereo amp vol pot has too little play at max setting. Read page 37 of the user manual for more info.
