ULTRAMATCH PRO SRC2496
3. APPLICATIONS
Digital outputs
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.

in 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 ULTRAMATCHPRO 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.
