15. Using more than one HDSPe AIO

The current drivers support operation of up to three HDSPe AIO. All cards of the HDSP and
HDSPe system use the same driver, therefore can be used at the same time. Please note that
only one TCO of one card can be used. All units have to be in sync, i.e. have to receive valid
sync information either via word clock or by using AutoSync and feeding synchronized signals.
If one of the HDSP systems is set to clock mode Master, all others have to be set to clock
mode AutoSync, and have to be synced from the master, for example by feeding word clock.
The clock modes of all units have to be set up correctly in their Settings dialog.
If all units are fed with a synchronous clock, i.e. all units show Sync in their Settings dialog,
all channels can be used at once. This is especially easy to handle under ASIO, as the ASIO
driver presents all units as one.
Note: TotalMix is part of the hardware of each HDSP system. 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.

16. DIGICheck

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 5.0 operates as multi-client ASIO host, therefore can be
used in parallel to any software, be it WDM, ASIO or GSIF, with both inputs and outputs (!). The
following is a short summary of the currently available functions:
• Level Meter. High precision 24-bit resolution, 2/8/18 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. As above, received pre-calculated
directly from the HDSP system hardware with near zero CPU load.
• Spectral Analyser. World wide unique 10-, 20- or 30-band display in analog bandpass-filter
technology. 192 kHz-capable!
• Vector Audio Scope. World wide unique Goniometer showing the typical afterglow of an
oscilloscope-tube. Includes Correlation meter and level meter.
• Surround Audio Scope. Professional Surround Level Meter with extended correlation
analysis.
• Totalyser. Spectral Analyser, Level Meter and Vector Audio Scope in a single window.
• 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. Detailled analyzis 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.
Follow the instructions prompted on the screen.
DIGICheck is conctantly improved. The latest version is always found on our website
www.rme-audio.de, section Downloads/Add-Ons.
