See the section on Connections for details of how to
make connections to and from the DS-M7.1.
1 Expansion slots The DS-M7.1 is fitted
with three expansion slots, which can take different
types of I/O card. Consult your TASCAM dealer for
details concerning the availability and the fitting of
these cards. When a card is fitted, it can be used as an
alternative to one of the three connectors immedi-
ately to the right of the slots, as described below.
NOTE
Although an analog IF-AN/DM card may be fitted in any
slot, only one such card may be fitted at a time.
2 SLOT 1/CONSOLE I/O (TDIF) This 25-
pin D-sub connector sends and receives up to eight
channels of digital audio in TDIF format to and from
a suitably-equipped digital mixing console such as
the TASCAM DM-24. If a card is fitted in slot 1, it
may be used as an alternative to this connector.
3 SLOT 2/TRK RECORDER I/O (TDIF)
This 25-pin D-sub connector sends and receives up to
eight channels of digital audio in TDIF format to and
from a suitably-equipped multitrack recorder, such as
the TASCAM DTRS series, or MX-2424 recorders.
If a card is fitted in slot 2, it may be used as an alter-
native to this connector.
4 SLOT 3/INSERT I/O (AES/EBU) This
25-pin D-sub connector sends and receives eight
channels of digital audio in AES/EBU format. It can
be used for inserting a surround encoder/decoder in
the monitoring path. If a card is fitted in slot 3, it may
be used as an alternative to this connector.
NOTE
When making connections to the DS-M7.1 using the
AES/EBU connectors, note that channels 1 and 2 must
always contain some signal. If there is no signal in these
two channels, no other AES/EBU channels can be
received. Also note that if the preamble is not correctly
received on a pair of AES/EBU input channels, those
channels will be muted.
5 MONITOR OUTPUTS There are two sets of
monitor outputs, which work in parallel, providing
up to eight channels of surround monitor outputs
apiece. Both are output from 25-pin D-sub connec-
tors and require appropriate “breakout” cables (con-
sult your dealer for details). The
ANALOG
connectors work as balanced +4dBu outputs, while
the
AES/EBU connector provides digital audio in
AES/EBU format.
6 STEREO CR INPUT These balanced
+4dBu inputs allow the stereo CR outputs from a
mixing console to be fed into the DS-M7.1, allowing
the same amplifier/speaker monitoring system to be
used for surround and stereo monitoring, without
repatching.
NOTE
Note the relationship between analog and digital signal
levels on the DS-M7.1. The maximum analog level is
+24dBu, equivalent to 0 dBFS digital. The nominal level
is +4dBU, corresponding to a digital level of –20dBFS.
7 WORD IN Use this BNC connector to receive
an external word clock signal. The 75
Ω
switch
allows termination to be set ON or OFF (usually ON ).
