The driver takes care of the numbering of all Firefaces, so that it doesn't change. The unit with
the lowest serial number is always 'Fireface (1)'. Please note:
• If the Fireface (1) is switched off, Fireface (2) logically turns to the first and only Fireface. If
Fireface (1) is switched on later, the numbering changes and the unit becomes Fireface (2)
immediately.
• The driver has no control on the numbering of the WDM devices. Therefore it might happen
that the WDM devices (2) are mapped to unit (1), especially when switching on more Fire-
faces during a Windows session. A reboot with all Firefaces already operational should solve
this problem.
Note: TotalMix is part of the hardware of each Fireface. Up to three mixers are available, but
these are separated and can't interchange data. Therefore a global mixer for all units is not
possible.
15. DIGICheck Windows
The DIGICheck software is a unique utility developed for testing, measuring and analysing digi-
tal audio streams. Although this Windows software is fairly self-explanatory, it still includes a
comprehensive online help. DIGICheck 5.5 operates as multi-client ASIO host, therefore can be
used in parallel to any software, be it WDM or ASIO, with both inputs and outputs (!). The fol-
lowing is a short summary of the currently available functions:
• Level Meter. High precision 24-bit resolution, 2/10/28 channels. Application examples: Peak
level measurement, RMS level measurement, over-detection, phase correlation measure-
ment, dynamic range and signal-to-noise ratios, RMS to peak difference (loudness), long
term peak measurement, input check. Oversampling mode for levels higher than 0 dBFS.
Vertical and horizontal mode. Slow RMS and RLB weighting filter. Supports visualization ac-
cording to the K-System.
• Hardware Level Meter for Input, Playback and Output. Reference Level Meter freely con-
figurable, causing near zero CPU load, because calculated from the Fireface hardware.
• Vector Audio Scope. World wide unique Goniometer showing the typical afterglow of a
oscilloscope-tube. Includes Correlation meter and level meter.
• Spectral Analyser. World wide unique 10-, 20- or 30-band display in analog bandpass-filter
technology. 192 kHz-capable!
• Totalyser. Spectral Analyser, Level Meter and Vector Audio Scope in a single window.
• Surround Audio Scope. Professional Surround Level Meter with extended correlation
analysis, ITU weighting and ITU summing meter.
• ITU1770/EBU R128 Meter. For standardized loudness measurements.
• Bit Statistics & Noise. Shows the true resolution of audio signals as well as errors and DC
offset. Includes Signal to Noise measurement in dB and dBA, plus DC measurement.
• Channel Status Display. Detailed analysis and display of SPDIF and AES/EBU Channel
Status data.
• Global Record. Long-term recording of all channels at lowest system load.
• Completely multi-client. Open as many measurement windows as you like, on any chan-
nels and inputs or outputs!
To install DIGICheck, go to the \DIGICheck directory on the RME Driver CD and run setup.exe.
