Based on many years of continued feature development of the ADI-2 Pro, RME unveils the next addition to the countless award winning ADI-2 Series. The latest masterpiece comes with a newly developed circuit board, improved specs and faster DSP for an outstanding transparent sound signature, extreme power headphone amplifiers including IEM power setting, super low noise 4.4 mm Pentaconn balanced connection, trigger out function for powering on/off external devices and finally an RIAA mode for directly digitizing vinyl discs in highest quality.

/A Multitude of Devices compressed in one Housing

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.
