The ADI-2/4 Pro EX represents the latest generation of its flagship AD/DA converter and mastering reference hub. The EX version combines updated conversion technology with numerous hardware improvements, optimized protection circuitry, and expanded analog functionality, further enhancing performance, accuracy, and reliability for professional applications in studios, mastering processes, and measurement tasks. It includes a new ES9823Pro A/D converter with improved signal-to-noise ratio (SNR) and THD+N values, as well as a new ES9039Q2M D/A converter with optimized signal-to-noise ratio (SNR), THD, and THD+N. It features a USB-C (USB 2.0) connector with a locking system (1.8 m cable included), independent per-channel DC protection for headphones, and an active, fuse-free protection system against reverse polarity and overvoltage. It has a ground terminal for turntables and other grounded connections. It is compatible with the new RM19-III rack-mount adapter. It incorporates SteadyClock EX technology, with factory calibration of ±1 ppm and user-configurable fine adjustment of ±50 ppm. It offers extended analog reference levels down to -35 dBu, RIAA equalization available in "Line" mode (0 dB gain), and selectable balanced input impedance (94 kΩ / 47 kΩ). ADAT channels 3/4 can be selected as the source for the headphone output. It also integrates ELAR (Extended Linear Analog Range) technology.
