Multimedia sources (samplers, CD, sound cards)
to Modular Digital Multitrack
Application
Modular digital multitracks allow recording on 8 tracks simultaneously, but if
those tracks are coming from different digital sources, they will not record
properly. A modular digital multitrack can only sync to one incoming digital
source at a time, and so any other incoming signals will be out of sync, with
resultant signal degradation.
The
DMTi
synchronizes the signals before they get to the modular digital multi-
track. Up to four channels of AES/EBU or S/PDIF audio from digital sam-
plers, 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 that this same setup can also be used with a digital mixer that has a
DA-88- or ADAT-compatible interface, as described on Page 13. The mixer
should be set up to lock to external sample-rate clock.
What you need
• The
DMTi
must have an ADAT or DA-88 (TDIF-1) option.
• AES/EBU (XLR, AES/EBU-to-S/PDIF, or optical) cables.
• Word clock cables if you are planning to lock to an external sync source.
• 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.
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 modular digital multitrack to the
DMTi
using the cable(s) pro-
vided with the recorder for connecting two decks together. The DA-88 uses
a single 25-pin “D” connector, while the ADAT uses one optical and one
sync cable for input, and a similar pair for the output.
• 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 — however…
• You must use the multitrack recorder as the sync master if you are
overdubbing tracks (see next page).
