Enjoy precise and reliable reference monitoring and conversion with the RME ADI-2/4 Pro EX, a flagship AD/DA converter which combines updated converter tech (ESS9823Pro A/D and ESS9039Q2M D/A chips) with hardware refinements and enhanced protection circuitry. With sampling rates as high as 768 kHz and two powerful headphone amps with DC protections, the ADI-2/4 Pro EX is ideal for mastering and measurement applications.

The DI-2/4 Pro EX features a locking USB-C connector for host connections, providing solid reliability in studio and mobile environments. Balanced line input impedance can be switched between 94 and 74 kilohms. Combined with a ground terminal and RIAA equalization support (in Line mode), the DI-2/4 Pro EX becomes an ideal choice for working with turntables and other earth connections. The analog circuitry has gotten plenty of upgrades, such as reference levels reaching down to -35 dBu and ELAR (Extended Linear Analog Range) technology for impressive transparency and a highly linear frequency response. SteadyClock EX offers excellent internal clock accuracy and fine tuning of ±50 ppm in 0.1 ppm increments. I/O includes XLR-1/4" TRS combo inputs, XLR 3-pin outputs, two independent 1/4" headphone outputs, a balanced 4.4mm headphone output, balanced 1/4" line outs, and a 3.5mm trigger output.
