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.

(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)  

—  (36)  DIGITAL INPUTS.

(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.

(1) 

Monitor and input sections. The monitor section enables 

you to adjust the signal level applied to the analog 

input and features a controllable headphone connector. 

A clearly structured LED array provides you with detailed 

information on the various parameters of the digital 

input signal.

(2) 

Mode section. Here, you can determine whether your 

ULTRAMATCH PRO is working as a sampling rate converter 

or A/D-D/A converter. 

(3) 

Output section. The buttons in the output section allow 

you to tailor the output signal to meet your requirements. 

 

Similarly to the input section, the display provides you 

with all the information on the output signal.

(4) 

Use the GAIN control to adapt the signal level perfectly to 

the circuitry of your ULTRAMATCH PRO. The level should be 

as high as possible, but the 0 dB LED should only light up 

occasionally or never at all to avoid distortion.

(5) 

The PHONES control governs the headphone volume. 

You can monitor either the analog output or input by 

setting the SOURCE switch accordingly. The analog 

output always provides the signal applied to the selected 

digital input, so this signal can be monitored with the 

headphones, too.

(6) 

This is the stereo 1/4" TRS connector for your headphones.

(7) 

The ANALOG IN and/or ANALOG OUT LEDs indicate 

which signal (input or output) is being displayed by the 

level meter.

(8) 

The SOURCE switch routes the analog input or output 

signal to the level meter.

(9) 

LEVEL METER. The signal shown here can always be 

monitored with the headphones.

(10) 

This LED array displays the sampling rate of the digital 

input signal. One LED lights up constantly when the 

sampling rate is kept accurately or does not deviate 

from the nominal value by more than approx. 2 kHz. 

Otherwise, the LED for the next value starts flashing.

(11) 

The LOCK LED lights up when a valid digital signal—

to which the ULTRAMATCH PRO can be synchronized—

is applied to the active input. When digital input signals 

are being processed, this LED should be on all the time, 

showing the presence of a stable input signal.

 The 

ERROR LED warns you of erroneous (or the absence of 

any) input signals. It displays various error modes, such as 

“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.

(12) 

The EMPH LED shows you whether or not the 

input signal includes an emphasis marker. 

“Emphasis” is a high-frequency boost function that 

is applied during the digital recording but is undone 

during playback. When the LED lights up, the signal 

was emphasis-processed during recording. You should 

always make sure that the EMPH LEDs in the input and 

output sections read the same status.

 The 

COPY LED (= copyright) lights up when the input 

signal was supplied from a copy-protected data carrier. 

 The 

ORIG LED (= original) informs you that the audio 

signal received is an original signal, i.e. that it can 

be copied.

(13) 

The AES/EBU LED lights up when an AES/EBU signal has 

been applied at the active input connector. 

 

The same holds true for the S/PDIF LED, i.e. when a 

consumer-format signal has been applied.

 

If the unit is set to A/D and D/A converter mode, 

the S/PDIF LED lights up even when no digital signal is 

present. This is due to the circuitry used and does not 

indicate a malfunction of the unit.

(14) 

Use the SOURCE switch to select the active input. 

Only one digital input can be activated at a time. 

However, in A/D-D/A converter mode, you can use one 

digital input and the analog inputs simultaneously 

(parallel A/D and D/A conversion).

(15) 

The LEDs XLR, RCA and OPTICAL indicate the input 

activated by the user. 

(16) 

The two LEDs SAMPLE RATE CONV and A/D & 

D/A CONV inform you about the operating mode 

of your SRC2496, i.e. sampling rate converter or 

A/D-D/A converter.

(17) 

Use the MODE switch to switch over between 

these two operating modes.

(18) 

The SAMPLE RATE switch selects the sampling rate 

to which the input signal is to be converted or made 

available at the outputs. 

(19) 

The LEDs 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz and 

96 kHz read the sampling rate selected with the Sample 

Rate switch. If the sampling rate is preset by an external 

wordclock or generated via the digital input signal, 

the LEDs light up constantly, thus reading the external 

sampling rate (with a deviation of ± 2 kHz). The next 

value (= deviation of >2 kHz) is displayed by one of the 

LEDs flashing. 

(20) 

The CLOCK switch allows you to select the source 

determining the sampling rate at the digital output 

of your ULTRAMATCH PRO.

(21) 

The PLL LOCK LED shows you that your SRC2496 

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).

(22) 

The FORMAT switch determines the format of the 

digital data stream on the output side, as defined in 

the Channel Status data. Available formats are AES/EBU 

and S/PDIF.

(23) 

The LEDs AES/EBU and S/PDIF show the adjusted 

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.

(24) 

Use the WORDLENGTH switch to select the digital 

word length of your choice (16, 20 or 24 bits). 

(25) 

The LEDs 24 BIT, 20 BIT and 16 BIT read the word 

length selected.

(26) 

The DITHER switch enables/disables the dither function.

(27) 

The EMPH LED lights up when the emphasis bit has 

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.

(28) 

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.

(29) 

MAINS CONNECTOR/FUSE HOLDER. 

(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.
