Fig. 3.1 shows a typical setup for recording a signal source on a digital recording 

device (here: hard-disk recording system). If your HD recording system is 

equipped with a digital interface, you can use the ULTRAMATCH PRO to 

“circumvent” the A/D converter on the sound card and thus avoid interference 

signals generated by the computer. By taking the signals from the subgroup 

outputs on your mixing console, you can record several signal sources at the same 

time by assigning (routing) them to the corresponding subgroups.
In practice, the ingenious design of the SRC2496 proves to be versatile to the 

point that you can also solve problems which are not directly related to a normal 

studio environment. For example, digital hi-fi recording equipment such as 

MD recorders (Mini Disc) have been met with widespread popularity in home 

systems. Unfortunately, however, such equipment cannot record with 32 kHz 

using their digital input.
Thus, it is impossible to record digital broadcasting programs directly to digital; 

D/A and A/D conversion steps are inevitable.
Not so with the ULTRAMATCH PRO, as it can convert the broadcast signal from 

32 kHz to any other common sampling rate and also remove any form of copy 

protect information. 
A second wiring setup shows how to copy tape recordings for restoring and 

subsequent archiving purposes on digital media.

3.1.2  Converting digital to analog
Using the ULTRAMATCH PRO as a digital-to-analog converter is interesting for 

all applications in which signals must be made audible again after digital 

processing, e.g. to “circumvent” D/A converters of inferior quality in equipment 

with a digital output (sound card).
This can be useful if your sound card is not shielded from electromagnetic 

interference generated by power supplies or graphics cards for example. You can 

feed the audio signal from the digital interface of the sound card to one of the 

digital inputs on the SRC2496 and then take it from the analog outputs. The type 

of cable required for connecting the sound card to the ULTRAMATCH PRO depends 

on the output connector used. 

3.1.3  Parallel A/D and D/A conversion
The SRC2496 offers you the possibility to simultaneously convert analog signals into 

digital, and vice versa. In A/D and D/A converter mode, you can only convert 

from digital to analog if the CLOCK switch in the output section has been set to 

DIG IN. In this case, the sampling rate will be determined by the digital signal 

applied. Otherwise, the ULTRAMATCH PRO can only be operated as an A/D 

converter, and the D/A converter function will be muted. In SRC mode the D/A 

converter is always active.
