The RME Babyface Pro FS and the Solid State Logic SSL 2+ are both high-quality audio interfaces, but they differ significantly in their specifications. The RME Babyface Pro FS boasts an impressive frequency response across various input types, with mic and line inputs ranging from 18 Hz to 20.8 kHz at -0.1 dB (44.1 kHz) and extending to 5 Hz to 88 kHz at -1 dB (192 kHz). In comparison, the SSL 2+ offers a more limited frequency response of 20 Hz to 20 kHz ±0.1 dB for mic inputs and ±0.05 dB for line and Hi-Z inputs, which may not cater to the same wide range of audio fidelity as the RME.Show More


When it comes to maximum input levels, the RME Babyface Pro FS allows for higher input levels on mic inputs, reaching up to +19 dBu with pad, while the SSL 2+ maxes out at +5.5 dBu. The line inputs on the RME can handle +13 dBu, compared to the SSL's +24 dBu. This indicates that the RME is designed for more dynamic range handling in lower-level signals, while the SSL caters better to higher level sources. Additionally, the RME features a headphone output power of 90 mW into 1000 Ohms, while the SSL 2+ provides a maximum of 10 dBu for headphone outputs, reflecting a more robust output capability in the RME.


The dynamic range of the Babyface Pro FS is also superior, with D/A converters providing a dynamic range of 115 dB RMS and an SNR of 113.7 dB RMS for mic/line inputs. In contrast, the SSL 2+ offers a dynamic range of 110.5 dB across its mic, line, and Hi-Z inputs. This difference indicates that the RME interface may deliver a clearer and more detailed audio signal in demanding recording situations.


Regarding total harmonic distortion (THD), the RME Babyface Pro FS achieves an impressive level of -112 dB / 0.00024% on line/mic inputs, while the SSL 2+ has a THD+N rating of <0.005% for mic/line/Hi-Z inputs, which is significantly higher in distortion. The RME's THD+N is also notably lower than that of the SSL, making it a better option for professional-grade recordings where purity of sound is paramount.


In summary, while both the RME Babyface Pro FS and Solid State Logic SSL 2+ are excellent audio interfaces, the RME offers superior specifications in frequency response, input levels, dynamic range, and THD performance, making it a more suitable choice for professional audio applications.
