ULTRAMATCH PRO SRC2496
2. CONTROL ELEMENTS
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 digital form. 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 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 some cutting-
edge technology. Today, a lot of hi-fi equipment is 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 unit.
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 refresherbut is still easy to operate.
The front panel of your ULTRAMATCH RO features a 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 SRC2496s 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.
For rack mounting, please use M6 metal nuts and bolts.
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 120 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.

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.
Mode section. Here, you can determine whether your
ULTRAMATCH PRO is working as a sampling rate converter
or A/D-D/A converter.
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.
