24. Stand-alone Operation
The Fireface 800 has an internal memory to permanently store all configuration data. These
are:
Settings dialog
Sample rate, clock mode Master/Slave, configuration of the channels and the digital I/Os.
TotalMix
The complete mixer state.
The Fireface loads those settings directly after power-on. A simple, yet useful application is to
store the correct clock mode, avoiding wrong clocking and noise disturbances in a complex
setup, caused by wrong synchronization. Usually the unit will be configured by the Windows
driver, so for the time between power-on of the computer up to the loading of the Windows
driver its state might be wrong.
This total configuration feature in stand-alone operation - without any connected computer -
turns the Fireface into lots of dedicated devices. Furthermore TotalMix (and with this all follow-
ing examples) can be MIDI controlled even in stand-alone operation, see chapter 32.7, Stand-
Alone MIDI Control.
24.1 10-Channel AD/DA-Converter
When loading TotalMix' factory default 1 into the unit, the Fireface becomes a high quality 10-
channel AD/DA-converter, which also provides a monitoring of all 8 DA-channels via channels
9/10 (Preset 2: also monitoring all 10 inputs). A small modification allows for a monitoring of all
I/Os via the SPDIF I/O.
24.2 4-Channel Mic Preamp
Use TotalMix to route the four microphone inputs directly to the analog outputs. This turns the
Fireface 800 into a 4-channel microphone preamp. The AD- and DA-conversion will cause a
small delay of the signals of around 0.4 ms (at 192 kHz, see chapter 35.2). But this is not really
relevant, as it is the same delay that would be caused by changing the microphone's position by
about 14 centimeter (5.6 inches).
24.3 Monitor Mixer
TotalMix allows ANY configuration of all I/Os of the Fireface. For example, set up the device as
monitor mixer for 10 analog signals, 16 digital via ADAT and 2 via SPDIF. Additionally, TotalMix
lets you set up ANY submixes, so all existing outputs can be used for different and independent
monitorings of the input signals. The perfect headphone monitor mixer!
24.4 Digital Format Converter
As TotalMix allows for any routing of the input signals, the Fireface 800 can be used as ADAT
to SPDIF converter, ADAT to two ADAT splitter, and SPDIF to ADAT converter.
24.5 Analog/digital Routing Matrix
The Matrix in TotalMix enables you to route and link all inputs and outputs completely freely. All
the above functionalities are even available simultaneously, can be mixed and combined in
many ways. Simply said: the Fireface 800 is a perfect analog/digital routing matrix!
