ULTRAMATCH PRO SRC2496

1. INTRODUCTION

1. INTRODUCTION

The BEHRINGER ULTRAMATCH PRO is a fully digital signal

processor integrating 24-bit A/D and D/A converters. With its wide

range of features, it provides a powerful state-of-the-art interface

between the physical reality of music and its recording in the form

of digital values. To retain the true authenticity of your music, we

not  only  developed  a  strong  link  between  analog  recording

technology  and  the  huge  variety  of  signal  processing  possi-

bilities  available  in  the  digital  world,  but  also  designed  the

ULTRAMATCH PRO SRC2496 to function as a universal inter-

face between the various digital formats and sampling rates.

Thus, incompatibilities between different devices and equipment

with regard to modified connectors, transmitted signals and applied

standards are definitely a thing of the past.

+

This manual first describes the terminology used, so

that  you  can  fully  understand  the  SRC2496  and  its

functions. Please read the manual carefully and keep it

for future reference.

1.1 The design concept

The philosophy behind BEHRINGER products guarantees no-

compromise circuit design and the best choice of components.

We only use low-tolerance resistors and capacitors, high-grade

switches and buttons as well as other select components to make

sure that you can fully benefit from state-of-the-art 24-bit/96 kHz

technology  with  regard  to  low  noise  and  high  dynamics.  With

the  ULTRAMATCH  PRO  you  have  purchased  cutting-edge

technology. Today, many hi-fi devices are already equipped with

a digital interface, so the SCR2496 can not only be used as a

high-end A/D and D/A converter in your studio, but also raises

your home hi-fi system to a new level in terms of dynamics, low

distortion and definition. It is thus possible to replace one of the

weak points in the signal chain with an absolutely powerful device.

The SRC2496 provides you with the functionality of a first-class

A/D and D/A converter, an outstanding sampling rate converter

and a digital patchbay. Additionally, it can be deployed as a format

converter, to set or remove copy bits, and as a signal refresher—

but is still easy to operate.

The front panel of your ULTRAMATCH PRO features a strictly

functional and easily understandable layout. On the left-hand half

of the panel you will find the monitor (left) and input sections (right),

the right-hand half includes the mode (left) and output sections

(right). Just imagine the signal passing through the unit from left

to right and the design logic becomes clear.

The monitor section enables you to monitor analog input/output

signals. The level meter reads the analog input level and allows

you to adjust it optimally. The status LEDs in the input section

make it easy to check which type of digital signal (AES/EBU or

S/PDIF) is being received and also display its sampling rate. Since

the ULTRAMATCH PRO is automatically synchronized to any input

signals within a range from 31 Hz to 100 kHz, there is no need for

dedicated sampling rate selector switches on the input side.

In the mode section you can see which of the SRC2496’s two

basic functions (A/D and D/A converter or sampling rate converter)

is currently active. Select the function of your choice at the touch

of a button. The output section gives you the buttons and displays

to adjust a variety of parameters for the digital output signal.

The ULTRAMATCH PRO stores the last setting made before

power-down, so you can continue from where you stopped when

you turn the unit back on again.

In a later section of this manual we will give you a detailed des-

cription of how you can use your ULTRAMATCH PRO in various

applications.

1.2 Before you begin

Your ULTRAMATCH PRO was carefully packed at the factory

and  the  packaging  is  designed  to  protect  the  unit  from  rough

handling. Nevertheless, we recommend that you carefully examine

the packaging and its contents for any signs of physical damage

which may have occurred during transit.

+

If  the  unit  is  damaged,  please  do  NOT  return  it  to

BEHRINGER, but notify your dealer and the shipping

company immediately, otherwise claims for damage or

replacement may not be granted. Shipping claims must

be made by the consignee.

The BEHRINGER ULTRAMATCH PRO requires one rack unit

for installation in a 19" rack. Please allow for an additional 4" of

rack depth for the rear panel connectors.

Be  sure  that  there  is  enough  air  space  around  the  unit  for

cooling.  For  example,  to  avoid  overheating,  do  not  place  the

ULTRAMATCH PRO on power amps.

+

Before  you  connect  your  ULTRAMATCH  PRO  to  the

mains, please make sure that your local voltage matches

the supply voltage required by the unit!

The fuse holder at the AC power connector has 3 triangular

markings. Two of these three triangles will be aligned with one

another. The ULTRAMATCH PRO is set to the voltage shown

next to these markings and can be switched over by twisting the

fuse holder by 180°. 

IMPORTANT: This does not apply to export

models designed exclusively for 115 V operation!

+

If you set the unit to a different mains voltage, be sure

to use a fuse of the correct type and rating! In chapter 6

“TECHNICAL  SPECIFICATIONS”  you  will  find  the

matching fuse type for your local mains voltage.

The mains connection is made by using the enclosed power

cord and a standard IEC receptacle. It meets all of the international

safety certification requirements.

+

Please make sure that all units have a proper ground

connection.  For  your  own  safety,  never  remove  or

disable the ground conductor of the unit or of the AC

power cord.

+

Please  ensure  that  only  qualified  persons  install  and

operate the SRC2496. During installation and operation

the user must have sufficient electrical contact to earth.

Electrostatic discharges might affect the operation of

the unit.
