The RME Fireface UCX II audio interface has several impressive specifications:
THD+N: For the line inputs 5-8 at the rear, the Total Harmonic Distortion plus Noise (THD+N) is less than -104 dB (0.00063%) (Synthax USA) (Audio46 Headphone Store).
DAC (Digital-to-Analog Converter): The output resolution is 24-bit with a dynamic range (DR) of 115 dBA (Synthax USA) (Audio46 Headphone Store).
Input Dynamic Range: The signal-to-noise ratio (SNR) for the analog-to-digital conversion on line inputs 5-8 is 115 dBA (Synthax USA) (Audio46 Headphone Store).
Output Dynamic Range: The dynamic range for the line outputs 1-6 is also 115 dBA (B&H Photo Video) (Synthax USA).
The interface supports various sample rates up to 192 kHz and provides extensive connectivity options including ADAT, AES, SPDIF, and MIDI. Additionally, it features SteadyClock FS for jitter reduction and can operate in stand-alone mode (Synthax USA) (Audio46 Headphone Store).
