Having two stereo outputs, balanced headphone operation is possible. As RME's engineers were not satisfied with the existing techniques they developed a new Advanced Balanced mode for the ADI-2 Pro, that removes most limitations of standard balanced operation, and turns this mode into a a fully new experience. The exclusive Advanced Balanced mode delivers a balanced signal path from the DAC straight to the phone, with 3 dB gain in Signal to Noise Ratio, smoothed out deviations in components, optimized frequency response, super low output impedance (0.2 Ohms), and a maximum output level of +28 (twenty eight) dBu.
