ULTRAMATCH PRO SRC2496

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 possibilities 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 refresher—but 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 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 description 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 "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.

2. Control Elements

Fig. 2.1: Front panel control elements
(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.
