The Fireface UFX+ from RME is an audio interface that combines analog, ADAT, MADI, AES, S/PDIF, USB 2, USB 3 and Thunderbolt connectivity, with the ability to handle up to 94 channels of audio I/O with ease. Also included are DURec (Direct USB Recording) and RME's renowned low-latency hardware and driver designs, making the interface especially suitable for situations where large amounts of data need to be moved about. For monitoring, low impedance Hi-Power headphone outputs provide ample power for driving any high- or low-impedance headphones.
Comprehensive MADI connectivity
In USB 2 mode, which is limited to 30 channels I/O (12 analog plus 16 ADAT plus AES), the MADI I/O is still available via RME's TotalMix FX digital mixer
Wordclock I/O (BNC) can be switched to MADI I/O (coaxial), and a special split mode supports the use of both MADI I/Os simultaneously, with 32 channel each on optical and coaxial
DURec, available on the front of the interface, offers second generation hardware with improved USB functionality and compatibility, providing greater reliability even with slower or multi-partitioned USB thumb drives
The maximum number of recordable channels has been raised to 76, meaning all 12 analog inputs plus 64 MADI channels can be recorded simultaneously
An internal Realtime Clock (RTC) delivers time-stamped files
TotalMix provides unlimited routing and mixing to the interface, with the capability to create as many independent submixes as output channels are available, and includes a complete effects system
TotalMix FX for iPad (available separately) adds full control over the mixer and DSP effects
