The Fireface 400 is not just the little brother of the Fireface 800 - it is a completely newly designed device. It is the only device in its class with active jitter suppression, stand-alone functionality, complete controllability from the front panel, highly flexible I/Os in professional quality, and an unsurpassed 648-channel matrix router - at sample rates up to 192 kHz. The DSP-based TotalMix mixer allows fully independent routing and mixing of all 18 input and output channels to all 18 physical outputs. Up to 9 totally independent stereo sub-mixes simply mean unrivalled monitoring facilities.
Copy/paste of routings, ganging and group-based operation of faders, and the extraordinary Matrix window are just some of the mixer's unique features. The mixer can be completely MIDI controlled, even in stand-alone operation. Furthermore the DSP hardware calculates RMS and Peak levels for all 54 audio channels, without causing any significant CPU load.
