to the transmitted rate and automatically cancels operation.
With the ULTRAMATCH, such restrictions are history. Correct operation is provided not only for a limited
range around the selected sample rate but for any sample rate between 25 kHz and 60 kHz. Moreover, the
signal transmitted by the ULTRAMATCH is always synchronized to a correct rate of 44.1 kHz or 32 kHz.
Therefore, deliberately changed sample rates (for instance, by a varipitch function provided in samplers and
certain CD players) as well as too unsteady rates can be corrected by the ULTRAMATCH and processed
further.
6.5Varispeed Applications
There may be several reasons to apply a change in speed to a digital recording, for example pitch change or
synchronization to other devices. In such cases, the ULTRAMATCH locks to changes in sample rates and
transmits the output signal with a fixed rate of 44.1 kHz or 32 kHz. Thus, it reliably solves any problems related
to unsteady sample rates in a multi-unit network which else would make digital processing of the material
impossible.
6.6Format Conversion
Quite often, format-related problems occur when a digital copy is drawn. While some devices explicitly require
SPDIF information at the input, others can only transmit signals in AES/EBU format. The ULTRAMATCH
solves this problem, too. It accepts signals in any known format. The output signal can be set either to AES/
EBU or SPDIF format. Thus, it makes digital copying a mere question of the correct switch to be pressed.
6.7Format Interface
A lot of CD players do not feature coaxial outputs but only optical ones. On the other hand, some DAT
recorders only provide coaxial inputs. Digital interfaces for home-recording purposes are only equipped with
either optical or coaxial connectors. If then a digital copy is to be drawn, the user finds out that one device
features an optical connector and the other one a coaxial RCA jack. A connection to professional devices is
difficult to establish because of the XLR jacks provided there, and consumer devices only equipped with optical
connectors cannot be connected to professional devices at all.
Such incompatibilities and problems with different inputs and outputs are solved when using the ULTRAMATCH.
For instance, if the CD player features only an optical digital output and the DAT recorder a coaxial RCA input,
the ULTRAMATCH provides any necessary input and output to establish the correct connection. Generally
speaking, any device available can be combined with any other!
6.8Patchbay/Split Operation
The inputs and outputs of the ULTRAMATCH can all be used simultaneously. In this case, the input selector
acts as a mini patchbay since it defines the signal to be output. There is no need to make a similar setting for
the output as the receiving unit decides if a signal is accepted or not (for example, by activated/deactivated
recording mode). Therefore, all outputs of the ULTRAMATCH are active at the same time, transmitting identical
signals.
This threefold signal output allows split operation. This can be useful if, for instance, a multiple copy is drawn
on several DAT recorders, or if a hearing check-up of the output signal is made by means of an additional D/
A converter. This feature is especially useful for devices that do not pass the input signal through to the output.
6.9The ULTRAMATCH in a home-recording studio
The ULTRAMATCH can be used as an integrated part of a home-recording studio, too, since many problems
the professional sound engineer has to face also apply to the dedicated music listener and composer: connec-
tion problems between optical and coaxial interfaces, SCMS removal, sample rate conversion from 48 kHz to
44.1 kHz, or a digital patchbay for various audio sources.
The sophisticated conception of the ULTRAMATCH proves so flexible in practical operation that even problems
