What Else Do I Need?
To connect your
DMTi
to a K2500 Series instrument, the K2500 will have to be
equipped with a KDS Output Option or KDFX Option. These options require
the K2500 to be running operating system version 2.3 or higher.
For hooking the
DMTi
up to an ADAT or DA-88, you’ll also need the appropri-
ate interface option installed into the
DMTi
. Contact your Young Chang/
Kurzweil dealer if you have any questions.
What Does It Do?
The principle behind the
DMTi
is relatively simple, although it is being imple-
mented with some very sophisticated technology. There are four sets of digital
inputs, in three different formats, and four sets of digital outputs, also in three
formats. Each input and output comprises two channels of audio. The signal
on each input is converted, and then routed to any one (or more) of the out-
puts.
The conversion process can change the sample-rate clock, either to a sample
rate determined by one of the other incoming audio signals; to the rate set by
incoming word clock; or to a rate set by the
DMTi
’s internal clock. Whichever
sample-rate clock is chosen serves as the master for the entire unit—therefore,
all four of the digital signals appear at the outputs in perfect synchronization
with each other.
The conversion process can also change the signal format, for example, from
AES/EBU to DA-88 (TDIF-1) or ADAT, or from the K2500’s proprietary “KDS”
format to S/PDIF, or from any supported format to any other. Although the
sample-rate clocks are all linked together, the format conversions of the various
audio streams can be independent of each other, and in fact multiple types of
format conversions can take place simultaneously.
The operation of the
DMTi
is very straightforward: there are no menus, hidden
functions, factory settings, or other obscure features to worry about. What you
see is what you get. However, the uses to which you can put the device are
quite varied—you might think of it as the “Swiss Army knife” of digital audio
tools.
