Multimedia sources to digital mixer
Application
With the advent of true digital mixers, it becomes crucial for there to be a way
to synchronize digital streams, so that multiple digital signal sources can be
used with these mixers. A digital mixer with AES/EBU inputs can only sync to
one incoming digital source—generally, it is the signal appearing at the first
input. If signals at the other inputs are not synchronized to the first signal,
audible errors will occur.
The
DMTi
synchronizes the signals before they get to the mixer. Up to four
channels of AES/EBU or S/PDIF audio from digital samplers, signal
processors, computer audio cards, DAT decks, and/or CD players can be
combined this way, along with two or more channels from a Kurzweil K2500-
series instrument.
Note
: if the mixer has DA-88- or ADAT-compatible inputs, you can treat it
exactly as if it were a multitrack digital recorder (see Page 13).
What you need
• AES/EBU (XLR, AES/EBU-to-S/PDIF, or optical) cables.
• If you are using a K2500-series instrument as one of the sources, it must be
equipped with a KDS digital input/output or KDFX digital effects option.
• Word clock cables if you are planning to lock to an external sync source.
• If the mixer uses ADAT- or DA-88-format digital inputs, then the
DMTi
must
have the appropriate option.
Hookup
• Connect the AES/EBU or S/PDIF sources to the
AES1
and
AES2
inputs.
• Connect the K2500 (if you are using one) to the
DMTi
’s
KDS In
connector
using the KDS cable included with the
DMTi
.
• Connect the digital mixer using either AES/EBU cables, S/PDIF cables and
adapters, or MDM cable(s), depending on the mixer’s input format. (Some
mixers with ADAT inputs do not have a Sync input, and only require the
optical cable to be connected.)
• If you want to use an external source of word clock as the sync master,
connect that source to the
DMTi
’s
Word Clock In
put.
• If the mixer also accepts external sample-rate sync, and you want to use it,
then connect it to the mixer’s word clock input.
