  • Build in ADAT or SPDIF optical I/O
  • AES/EBU and SPDIF coaxial I/O
    (via breakout cable)
  • 2 x “Extreme Power“ headphone outputs
  • 1 x Balanced Pentaconn headphone output
  • 1 x USB 2.0
  • 1 x 3.5mm trigger output
  • 'MRC' (Multi-Remote-Control)

The ADI-2/4 Pro SE is a 2-channel analog input to digital and 4-channel digital to analog output converter in a half-rack (9.5") enclosure of 1 U height. Latest 32 bit / 768 kHz converters offer up to 123 dBA signal to noise ratio. Reference class tech specs throughout are combined with an unprecedented feature set. A powerful DSP adds all kinds of useful audio processing, including 5-band parametric EQ, fast Bass/Treble adjustment, Crossfeed, and a new concept in Loudness sound control.

The ADI-2/4 Pro includes two servo-balanced analog inputs on combo XLR / TRS jacks, two separate balanced and unbalanced outputs on XLR and TRS, two stereo Extreme Power headphone outputs on the front for easy balanced operation of all headphones, including IEMs via Pentaconn connector.

Also available are optical SPDIF I/O, which also understands ADAT, as well as coaxial SPDIF (RCA) and AES I/O (XLR) via an included breakout cable. This universal set of I/O options offers superior quality and flexible connectivity to those who take a no-compromise approach to audio.

With independent balanced outputs for Line and Phones, balanced phones no longer mutes the rear outputs. Balanced Line and Balanced Phones outputs can be used simultaneously, even with different sources/signals. The balanced TRS in the back can be fed from Line 1/2 or Phones 3/4 signal path, perfect for handling insert effects during the mastering process.

A high resolution IPS panel for the graphical operation surface eases operation even more, and displays further functions provided by the DSP, namely Peak level meters, a 30-band analyzer in DIGICheck biquad filter technology, and a State Overview screen listing the current states of SPDIF, AES, USB and clock.

The USB 2.0 port is fully Class Compliant (UAC 2.0) a standard that is natively supported by operating systems like iOS, macOS, Linux and Windows 10 (since 1709), and is also used for firmware updates. Including an external switched power supply with lockable connector, the ADI-2/4 Pro can be easily powered from battery, opening up mobile applications as well as galvanically isolated use cases.

As a computer interface the ADI-2/4 Pro offers a stereo (2 in / 2 out) and a multichannel mode (6 in / 8 out). Compatibility with macOS comes right out of the box. Under Windows the ADI-2/4 Pro uses RME's MADIface series driver, for full WDM and ASIO compatibility and highest performance.
