ULTRAMATCH PRO SRC2496

3. APPLICATIONS

Fig. 2.8: Wordclock connector

The  BNC  connector 

WORDCLOCK

  is  a  high-impedance

connector with no internal terminating impedance (75 ohms).

Use it to connect devices for the external synchronization of

your ULTRAMATCH PRO. Please note the instructions given

in chapter 3.2.3.

Fig. 2.9: Digital outputs

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.
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.

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.

 DIGITAL INPUTS

.

The 

RCA

 input is the digital standard input for S/PDIF signals.

The 

OPTICAL 

input (Toslink) is also used for S/PDIF signals.

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.

ANALOG OUTPUTS

. These balanced analog XLR outputs

(stereo) provide the analog signal generated by conversion

from a digital format.

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 

).

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:

this device 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  suggests  itself  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.

3.1 A/D and D/A conversion with the

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.
