Cables and adapters
KDS
The
DMTi
ships with a three-meter cable for connecting it to the Kurzweil
Digital Stream (KDS). This cable is used to link the
DMTi
with a Kurzweil
K2500-series instrument (equipped with the KDS or KDFX option), and/or to
link two
DMTi
s together. It is a proprietary 15-pin format. A 15-meter KDS
cable is available from your Kurzweil dealer.
MDM
An interface for a modular digital multitrack tape recorder is available as an
option for the
DMTi
. There are two models: one for use with ADAT-type decks,
made by Alesis, Fostex, and Panasonic; and the other for use with
DA-88 (or “TDIF”) type decks made by TASCAM and Sony. Whichever option
you choose comes with connectors that are the same as on the deck itself, so
that connecting the
DMTi
to the deck is just like connecting a second deck to
the tape deck. Consequently, the cable that is supplied with the deck for this
purpose can be used with the
DMTi
: a 25-pin connector for the DA-88, and two
optical connectors and two DB-9 sync connectors for ADATs. Note that
although an ADAT optical cable is physically the same as an AES or S/PDIF
optical cable, the two formats are not compatible: you won’t do any damage if
you connect one to the other, but you won’t get any signal.
S/PDIF
The AES/EBU inputs and outputs can be used with S/PDIF digital audio
signals (also known as “CP-340 Type II” and “AES Consumer” formats).
S/PDIF signals use single-conductor shielded video cable, terminated in RCA
(phono-type) jacks. (They can also use optical fibre cables.) There are
differences between AES/EBU and S/PDIF involving signal level, line
impedance, and channel status data. The circuits used at the
DMTi
’s digital
inputs are sensitive and tolerant enough to accept either kind of signal.
