2. THE CONCEPT
The BEHRINGER ULTRAMATCH is an especially flexible device meeting all the requirements of digital appli-
cations. Compared to most conventional sample rate converters, the ULTRAMATCH offers much more than
mere sample rate conversion, due not only to various options for signal manipulation but also the provision of
the complete input and output interface.
The front panel of the ULTRAMATCH is strictly functional and has a user-oriented design. The nature of the
input signal and the selected mode of processing can be identified plainly. An separate error LED indicates the
presence of a valid input signal, another LED points to a set emphasis bit. Since the ULTRAMATCH automati-
cally synchronizes to any input signal with a sample rate between 25 kHz and 60 kHz, no selector is neces-
sary for the input sample rate.
A convenient feature is the manipulation of a set emphasis bit which means that the audio signal is not
changed, but only the identification contained in the digital data flow. You will usually activate the „auto“
function that automatically passes the emphasis information through. In theory, this is standard because
sound material recorded with (pre-) emphasis (fixed high-frequency boosting) has to be replayed with
(de-) emphasis (fixed high-frequency cut) in order to avoid falsifying the signal.
In every-day studio life, however, it may be different. It is known that sometimes during mastering and cutting
processes, the emphasis bit is set by defect hardware or software, though no high-frequency boosting is
executed. Usually, this error remains unnoticed during the duplication process since most modern DAT re-
corders do not provide an emphasis indicator anymore. The subsequent delivering of the DAT tape becomes a
rude awakening for the customer: The high-frequency cutting cannot be repaired anymore, and the sound
quality is characterized by the absence of any brilliant high frequencies. That is why we provided the
ULTRAMATCH with a special emphasis indicator as well as with a selector that allows to correct the emphasis
bit manually.
2.1 The Quality of Components and Circuits
Due to our company’s philosophy we only employ perfectly developed circuits and first-choice components.
The heart of the ULTRAMATCH is a special SRC processor that dues to its specifications and excellent sound
quality can be referred to as one of the best components ever used in digital processing. Additionally, low-
tolerance resistors and capacitors, high-quality transmitters and switches, special digital circuits, and further
carefully selected components are employed.
2.2 Digital Inputs and Outputs
2.2.1 XLR
The digital XLR inputs and outputs are not limited to the AES/EBU standard. They send and receive data in
either professional and consumer format. It is even possible to connect the RCA output of a CD player, for
example, to the XLR input of the ULTRAMATCH by means of an adapter(if for example the RCA input is
connected to another device in a fixed installation).
2.2.2 RCA
The digital RCA inputs and outputs are not limited to the SPDIF standard. They send and receive data in either
professional and consumer format. It is even possible to connect the XLR output of the BEHRINGER
ULTRA-CURVE PRO DSP8024, for example, to the RCA input of the ULTRAMATCH by means of an adapter.
The opposite (RCA output of the ULTRAMATCH to an XLR input of another device) depends on the sensitivity
of the XLR input concerned but should also normally work without problems.
2.2.3 Optical (TOSLINK)
The optical inputs and outputs are not limited to the SPDIF standard. They send and receive data in either
professional or consumer format.

Note: Many low-end devices require the consumer format sent by the ULTRAMATCH, other-
wise they will not accept the signal.
