16. Using multiple MADIface XT

OS X supports the usage of more than one audio device by the same audio software. This is

done via the Core Audio function Aggregate Devices, which allows to combine several devices

into one. This function is found in the Audio MIDI Setup – Audio window. Click the + sign in the

lower left.

The current driver supports up to three MADIface. All units have to be in sync, i.e. have to re-

ceive valid sync information either via word clock or by feeding synchronized signals.

• If one of the units is set to clock mode Master, all others have to be set to clock mode

Slave, 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 the 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.

Note

: TotalMix is part of the hardware of each MADIface. 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.

17. DIGICheck Mac

The DIGICheck software is a unique utility developed for testing, measuring and analysing digi-

tal audio streams. Although this Mac software is fairly self-explanatory, it still includes a com-

prehensive online help. DIGICheck 0.690 operates in parallel to any software, showing all input

data. The following is a short summary of the currently available functions:

• Level Meter. High precision 24-bit resolution, 2/8/198 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, receives pre-calculated

data directly from the MADIface 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 a

oscilloscope-tube. Includes Correlation meter and level meter.

• 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.

• 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 the in-

staller. Follow the instructions prompted on the screen.

DIGICheck is constantly updated. The latest version is always available on our website
