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.

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.
ULTRAMATCH PRO SRC2496
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.
+
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.
+
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°.
+
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.

Monitor and input sections. The monitor section enables you
to adjust the signal level applied to the analog input and
features a controllable headphones 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 works 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.
