The ERROR LED warns you of erroneous (or the absence of
determining the sampling rate at the digital output
any) input signals. It displays various error modes, such as
of your ULTRAMATCH PRO.
"Unlock," "Parity Error," "Bi-Phase Error" and "Confidence
Error." The signal is then checked as to whether or not
it is an audio signal. Any detected error makes the
SRC2496 mute all of its outputs to protect down-stream
audio equipment. As long as the ERROR LED is lit,
the ULTRAMATCH PRO cannot process any input signals.
The PLL LOCK LED shows you that your SRC2496
(21)
is processing properly the wordclock signals applied.
The INTERNAL LED lights up when the SRC2496
generates the sampling rate by itself (master), which is
the preferred mode for the ULTRAMATCH PRO acting as
an A/D converter.
The EXTERNAL LED lights up when the sampling rate is
governed by an external wordclock signal. The external
mode also allows you to generate sampling rates at the
output that could not be generated by the SRC2496 as a
master unit.
When the DIG IN LED lights up, your SRC2496 uses the
wordclock signal included in the digital audio signal fed
into the unit. This setting is useful if you do not want to
convert the sampling rate, but only the format of the
digital output signal (S/PDIF to AES/EBU or vice versa).
The FORMAT switch determines the format of the
(22)
digital data stream on the output side, as defined in
the Channel Status data. Available formats are AES/EBU
and S/PDIF.
The LEDs AES/EBU and S/PDIF show the adjusted
(23)
output format, which is present at all three digital
outputs. Using an appropriate cable you could also route
an S/PDIF signal from the XLR output to a second unit,
in case the RCA output is already in use.
Use the WORDLENGTH switch to select the digital

word length of your choice (16, 20 or 24 bits).
The LEDs 24 BIT, 20 BIT and 16 BIT read the word

The DITHER switch enables/disables the dither function.

The EMPH LED lights up when the emphasis bit has
(27)
been set in the output signal. Use the EMPHASIS
switch to enable/ disable this function. To avoid sound
deterioration, the LED in the output section should read
the same status as the EMPH LED in the input section.
In the rare case of a signal containing an emphasis bit
without any treble boost applied, you can correct this
here and switch off the emphasis bit.
The COPY switch (= copyright) allows you to set the

status of the copy bits in the transmitted data stream.
The LEDs COPY and ORIG inform you about the current
status of the copy protection.

Quick Start Guide
The digital XLR output is the standard output
(31)
connector for AES/EBU signals (AES/EBU LED lights up).
When S/PDIF is selected, the XLR output also provides
this signal.
This is the OPTICAL (Toslink) output connector of the
(32)
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.
DAT-Recorder
RCA output. The digital standard format for this output
(33)
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.
