TASCAM DS-M7.1

Rear panel

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

switch

allows termination to be set

ON

or

OFF

(usually

ON

).
