ULTRAMATCH PRO SRC2496
The following figure illustrates how to correctly connect the optical
input and output connections.

For many consumer devices the consumer format at the
optical input is an absolute necessity, otherwise they
do not accept the signal.

The ULTRAMATCH PRO does not support the ADAT ®
multi-track format, which can thus neither be looped
through nor converted.*
5.3.4 Wordclock
Feeding a wordclock signal into the rear BNC connector enables
external synchronization of the ULTRAMATCH PRO. Wordclock
signals are normally distributed in a network configuration, i.e.
are relayed and terminated with 75-ohm coaxial cable,
BNC-T adapters and terminating resistors. Commercially available
BNC cables are usually used as connecting cables. In order to
offer maximum flexibility, the ULTRAMATCH PRO’s BNC input
has a high-impedance design and is not equipped with an internal
75-ohm terminating resistor. Should the ULTRAMATCH PRO be
the last device in the signal chain, however, it is necessary to put
a T-connector into the BNC connector. A 75-ohm terminating
resistor (in the form of a short BNC plug) goes on one end of the
T-connector and the BNC cable from the “master” delivering the
wordclock signal on the other end.
The following figure shows how to correctly connect the
unbalanced wordclock input. The wiring scheme is the same as is
used for networking in computer technology and you can thus
obtain the appropriate accessories (commercially available cable,
T-connectors, terminating resistors) in specialist computer shops.

input to the ULTRAMATCH PRO
When the ULTRAMATCH PRO is used as part of a chain of
wordclock devices, it is also supplied with a wordclock signal via
a T-connector, which is then relayed to the next device from the
other side of the T-connector via an additional BNC cable. The
last device in the chain is then, as previously described, locked by
way of the T-connector and a 75-ohm resistor. Some devices also
have a switchable terminating resistor, in which case the
T-connector and terminating resistor are not necessary.

5.3.5 Connecting with an adapter
In certain cases it makes sense to connect the SRC2496’s inputs
and outputs to other devices via a cable adapter. If, for example, you
wish to simultaneously connect two DAT recorders and each has
only one RCA (S/PDIF) connector, you can easily connect one of the
DAT recorders to the ULTRAMATCH PRO using an XLR/RCA
adapter. The correct connection assignment of the adapter cable for
this purpose can be found in fig. 5.2.
5.4 Headphones output
The headphones output on the front panel of the SRC2496 is
on a 1/4" TRS connector. The connection assignment of the
corresponding plug is shown in fig. 5.8.

Please note that high volume levels can damage your
hearing and/or your headphones. Turn the PHONES
control to the far left before turning on the device. Always
take care to keep the volume level at an appropriate level.
