[. . . ] There are two separate coaxial jacks (cinch) for recording and playback. The interface can send and receive sample rates of up to 24-bit / 96 kHz. The recording driver is called "UF400e (0) SPDIF In", and the routing must be set to the digital output in the Control Panel for playback. Synchronization. When recording from a digital source, make sure that the sampling rates of both devices (e. g. DAT recorder and laptop) are synchronized. The S/PDIF protocol contains a signal for this purpose. If such a signal is applied to the digital input and the Master Clock switch is set to "External", the UF400e will automatically synchronize to it and the "Digital In" channel will be available in the mixer. ASIO applications such as Cubase SX often have an option to switch the hardware from an internal to an external (sometimes also called S/PDIF) clock source. This changeover currently has no effect on the UF400e. The switch to an external clock is not to be confused with external synchronization to MIDI devices, video equipment or tape decks and therefore cannot be found in the Sync, MIDI Clock, MTC or SMPTE settings of the applications. AC3 and DTS can also be played back via the digital output. Select "NonAudio " for the digital output in the Control Panel under "Routing". This setting mutes the Digital Play path in the digital mixer so that the non-audio signals are not also sent to the analog outputs. Practical tip: For an absolutely clean and jitter-free signal path (when mastering, for example), use special shielded RCA cables to transfer digital data. MIDI interface MIDI IN/OUT/THRU is available for suitably-equipped peripherals such as MIDI keyboards, DAW controllers and other devices. The cables for MIDI connections are 16 UF400e Firewire Audio Expansion Board Users Manual always connected "crosswise", meaning OUT to IN and vice-versa. MIDI sequencer software usually offers you to loop MIDI data through, using the Through function. Drivers The Windows drivers The UF400e audio interface features a range of drivers for a variety of applications. The audio drivers support all bit rates between 8 and 32 bits with all common sample rates between 32 and 192 kHz. (Digital I/O up to 96 kHz) The MME wave driver. In most Windows programs, you will encounter drivers with the designation " UF400e (0) MC Out" for recording and playback. These are multichannel drivers that support all six outputs (4 analog and 2 digital). The specific routing options for these drivers can be found in the UF400e Control Panel. The ASIO driver and the ASIO Control Panel The abbreviation ASIO stands for "Audio Streaming Input Output" and refers to a 32-bit driver model developed by Steinberg. The advantage of the ASIO driver is the extremely low audio recording and playback delay times, also known as latency. Values significantly under 10 ms--and less than 4 ms on fast, cleanly-configured systems--at sample rates exceeding 96 kHz are quite realistic. The format also supports sound Boards with multiple inputs and outputs--so-called multi-I/O Boards --as well as direct monitoring and multi-client mode (ASIO 2. 0 or later). [. . . ] Test the settings made above in the right-hand part of the window and save them when you're satisfied. Once saved, you can find your personal color settings in the dropdown menu, which already contains a number of examples. The "Windows System" color set uses only colors that display correctly at an 8-bit color depth. Scenes Faced with such a wealth of settings, it would be pretty tedious to have to set things up by hand every time. Needless to say, you can count on us to make your life easier with our extremely practical "Scenes" menu item. [. . . ]
