Routing and Monitoring with TotalMix

The HDSPe AoX-D features a powerful real-time digital hardware mixer, the Hammerfall DSP Mixer, which leverages RME’s unique, sample-rate independent TotalMix technology. This advanced mixer provides virtually unlimited mixing and routing capabilities, enabling all inputs and playback channels to be routed simultaneously to any hardware output.

Key Applications of TotalMix

  • Delay-Free Submixes (Headphone Mixes)
    Create up to 128 fully independent stereo submixes. This is equivalent to having 256 Aux sends on an analog mixing desk!

  • Unlimited Routing
    Route inputs and outputs freely, enabling flexible patchbay functionality.

  • Signal Distribution
    Distribute signals to multiple outputs simultaneously.

  • TotalMix includes advanced splitter and distributor features.

  • Simultaneous Playback of Multiple Programs
    The ASIO multi-client driver allows several programs to use the same playback channels concurrently.

  • TotalMix can mix and monitor these programs on a single stereo output, even when originating from different playback channels.

  • Mixing Input and Playback Signals
    Combine input signals with playback signals for comprehensive ASIO Direct Monitoring (ADM).

  • RME pioneered ADM technology and offers the most complete implementation available.

  • Integration of External Devices Use TotalMix to insert external effects devices into playback or recording paths.

  • This functionality supports inserts or effects sends/returns, ideal for real-time monitoring with effects such as reverb on vocals.

Features and Level Monitoring

Every input channel, playback channel, and hardware output includes a Peak and RMS level meter. These meters are calculated in hardware and are invaluable for verifying the presence of signals and their routing destinations.

Key Concepts for Understanding TotalMix

  • Recording Path
    As illustrated in the block diagram below, the recording signal remains unaltered.

  • TotalMix does not interfere with the record path or affect the recorded audio’s level or data, except when using loopback mode.

  • Flexible Routing and Independent Levels
    Hardware input signals can be routed to multiple destinations with independent levels.

  • Unlike conventional mixing desks, where the channel fader controls all routing destinations simultaneously, TotalMix provides granular control.

  • Level Meter Placement
    Input and playback channel level meters are pre-fader, allowing you to monitor signal presence at their sources. Hardware output level meters are post-fader, showing the actual output levels.

TotalMix offers unparalleled flexibility and precision, making it an indispensable tool for professional audio workflows.
