Fig. 3.1: Example: A/D conversion of a microphone signal
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.

Since subgroup outputs on mixing consoles, as well as tape and line
outputs on hi-fi amplifiers, usually provide unbalanced signals only,
please note the corresponding instructions on how to connect the
SRC2496 (chapter 5 "Installation").
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.

chapter 5 "Installation".
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.
