L.1 bis L.6, PH, SP, A.1 bis A.8
The output levels of these outputs can be defined in the range +6 dB down to –58 dB in steps of
1 dB. Additionally the setting maximum attenuation (Mute) is available. The gain change is per-
formed digitally by TotalMix.
Stereo Mode
Pushing the knob for more than a second activates the Link (Gang) mode. The display will show
off or on. In stereo (on) mode, the display only presents the left channels of a stereo pair (L1,
L3, L5...). The gain and volume setting is then valid for both channels.
20.2 8-Channel AD/DA-Converter
When loading TotalMix' factory default 1 into the unit, the Fireface becomes a high quality 8-
channel AD/DA-converter, which also provides a monitoring of all 8 DA-channels via channels
7/8 (Preset 2: also monitoring all 8 inputs). A small modification allows for a monitoring of all
I/Os via the SPDIF I/O.
20.3 2-Channel Mic Preamp
Use TotalMix to route the two microphone inputs directly to the analog outputs. This turns the
Fireface 400 into a 2-channel microphone preamp. The AD- and DA-conversion will cause a
small delay of the signals of around 0.35 ms (at 192 kHz, see chapter 30.2). But this is not
really relevant, as it is the same delay that would be caused by changing the microphone's posi-
tion by about 12 centimeter (5 inches).
20.4 Monitor Mixer
TotalMix allows ANY configuration of all I/Os of the Fireface. For example, set up the device as
monitor mixer for 8 analog signals, 8 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!
20.5 Digital Format Converter
As TotalMix allows for any routing of the input signals, the Fireface 400 can be used as ADAT
to SPDIF converter, and SPDIF to ADAT converter.
20.6 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 400 is a perfect analog/digital routing matrix!
