RME ADI-2/4 Pro EX AD/DA Converter - Special Order

A Multitude of Devices compressed in one Housing

The ADI-2/4 Pro EX 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 127 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.

RME ADI-2/4 Pro EX Features:

• Latest-generation RME flagship AD/DA converter and reference mastering hub with extensive digital and analog connectivity, powerful DSP processing, flexible routing, and comprehensive metering
• ESS9823Pro ADC and ESS9039Q2M DAC deliver a full generational improvement in SNR, THD+N, and conversion accuracy
• Refined ELAR technology pairs the new ESS converter architecture with precision-optimized filtering for reference-grade transparency and exceptionally linear frequency response throughout the signal path
• SteadyClock EX ships factory-calibrated to ±1 ppm precision for a stable, accurate internal clock right out of the box
• User-adjustable ±50 ppm sampling rate fine-tuning in 0.1 ppm increments achieves tight external sync without dedicated word clock hardware ("Sync without Sync")
• Analog reference levels down to -35 dBu support direct input connections from dynamic microphones without requiring an in-line lifter
• RIAA equalization in Line mode (0 dB gain) integrates external phono preamps and moving coil cartridge systems directly into the signal chain
• Selectable balanced input impedances of 94k ohms and 47k ohms optimize the input section for balanced moving magnet cartridges
• Improved DAC SNR reduces headphone output noise floor at lower reference levels in both Unbalanced and Balanced mode
• ADAT channels 3/4 selectable as the direct headphone source for flexible digital monitoring routing without external patching
• Channel-independent DC protection on each headphone output isolates individual channel failures from the rest of the system
• Active fuse-less circuitry detects and blocks reverse polarity and overvoltage before damage can occur
• Dedicated ground terminal accommodates turntable connections and provides an earth connection where required
• Lockable USB-C connection (USB 2.0) with included 5.9-ft. cable prevents accidental disconnection during critical sessions
• Compatible with the RM19-III rackmount adapter for clean installation in standard rack environments
