Fig. 2.7: Wordclock connector
(30) The BNC connector WORDCLOCK is a high-impedance connector with no
internal terminating impedance (75 Ohms). Use it to connect equipment
for external synchronization of your ULTRAMATCH PRO. Please note the
instructions given in chapter 3.2.3.

Fig. 2.8: Digital outputs
(31) The digital XLR output is the standard output connector for AES/EBU signals
(AES/EBU LED lights up). When S/PDIF is selected, the XLR output also
provides this signal. Further information on these connectors can be found
in chapter 5.3.
(32) This is the OPTICAL (Toslink) output connector of the ULTRAMATCH PRO.
When the unit is shipped, the optical Toslink input/output connectors
have dummy plugs attached to protect them from dirt and to prevent the
emission of light. These dummy plugs can be removed easily if you wish to
use the connectors. The digital standard format for this output is S/PDIF.
However, you can also transmit AES/EBU signals via this output.
(33) RCA output. The digital standard format for this output is also S/PDIF.
If AES/EBU has been selected in the output section, this output also provides
AES/EBU signals. Unlike the XLR connector, however, this output allows for
unbalanced signal transmission.

(34) The RCA input is the digital standard input for S/PDIF signals.
(35) The OPTICAL input (Toslink) is also used for S/PDIF signals.
(36) XLR input. The digital XLR input is the standard input connector for AES/EBU
signals. It can also be used to feed in S/PDIF signals, like the RCA and
OPTICAL inputs which can be used to process AES/EBU signals in addition to
the S/PDIF format.

(37) ANALOG OUTPUTS. These balanced analog XLR outputs (stereo) provide the
analog signal generated by conversion from a digital format.
(38) ANALOG INPUTS. Use these balanced analog XLR inputs (stereo) to feed in
analog line level signals. Please note the instructions on level adjustment
given in chapter 2.1.1 (section (4) ).

3. Applications

Your ULTRAMATCH PRO will soon prove to be a practical tool of valuable help
in almost any situation. Its straightforward user interface is fun to work with.

Don't be misled by the plain design: the SRC2496 is a really flexible tool in a
variety of applications.
You don't need to own a professional recording studio to benefit from the wide
range of features and functions implemented in the SRC2496. Problems with
the interfacing of optical and coaxial connectors, removing copy protect bits,
converting sampling rates from 48 to 44.1 or 32 kHz—all of these tasks are quite
common daily routines even in a home recording environment.
Additionally, the ULTRAMATCH PRO is the logical choice as a high-end A/D and
D/A converter or enhanced source selector for digital inputs—whenever you
need an inexpensive and reliable alternative to equipment with considerably
higher prices.

ULTRAMATCH PRO
3.1.1 Converting analog to digital
The ULTRAMATCH PRO is equipped with high-grade A/D and D/A converters.
With the SRC2496 you own an excellent tool for preparing your analog audio data
for digital processing or for converting analog signals directly and storing them
on a digital medium. The analog input is set for studio levels (+4 dBu), but can be
adapted to low-level signals with the GAIN control. Please use the level meter to
adapt the level of the input signal, as described in chapter 2.1.1. The illustrations
3.1 and 3.2 below show you how to connect the unit.
