Mobile Device Compatibility

The RME Fireface UFX III audio interface boasts enhanced compatibility with both Windows and macOS, further emphasizing its versatility in modern audio production environments. It operates using a USB 3.0/3.1/3.2 Gen 1 Port, ensuring high-speed data transfer, which is essential for handling its impressive 188-channel capability. However, it does not include any bundled software or plugins, nor does it support mobile applications, making it primarily a desktop-focused device.Show More


In contrast, the RME Fireface UFX II also supports both Windows and macOS operating systems, but it has a more specific system requirement, necessitating macOS 10.6 or later and Windows 7 or later. It requires an Intel Core i5 processor as a minimum, which could limit its use on older systems. The UFX II stands out with its compatibility for mobile apps, specifically designed for iPadOS. The TotalMix FX app allows users to adjust settings and control the audio interface remotely, adding a layer of convenience for mobile producers.


While both interfaces cater to professional audio needs, the RME Fireface UFX III positions itself as a more high-capacity, desktop-centric solution without mobile app support, focusing on extensive channel management. Conversely, the RME Fireface UFX II offers mobile app compatibility, making it a more flexible option for users who require remote control capabilities on iPad devices, albeit with a lower channel capacity and specific processor requirements.

The RME Fireface UFX III and RME Fireface UFX II are both high-quality audio interfaces designed for professional use, yet they differ in power consumption specifications. The UFX III has a power consumption of 38 W, while the UFX II consumes 19 W (Idle) and 25 W (Typical). This difference indicates that the UFX III may require more power under similar operating conditions compared to the UFX II.Show More


Both interfaces share similar power requirements, accepting an AC input range of 100 to 240 VAC at 50 / 60 Hz. This feature ensures compatibility with various power systems globally, making both models suitable for international use. However, the increased power consumption of the UFX III could be a consideration for users mindful of energy efficiency.


In summary, while both the RME Fireface UFX III and RME Fireface UFX II offer robust specifications for professional audio interfaces, the UFX III's higher power consumption might influence a user's choice depending on their specific needs and power management preferences.
