1 – About the unit
allowing almost every common industry format to be
supported by the DS-M7.1.
Full calibration facilities are provided, with a built-in
pink noise generator, to allow for quick, easy and
accurate setup of the unit. Channel delay is provided
to compensate for acoustic delay when surround
speakers are used in a large space.
An analog or digital insert can be placed in the monitoring path, in order to hear the surround mix through
a surround encoder. This is useful for hearing the
effect of the encoding process.
Muting and soloing of individual channels, with flexible soloing options, allows checking of any desired
combination of surround channels.
SPL indication and control is available from the front
panel, allowing the surround monitoring to be carried
out accurately, according to the different guidelines
and standards within the industry.
A dedicated pair of analog stereo inputs can be fed
from the console’s main control room outputs, allowing the same speaker/amplifier system to be used for
the L and R channels in both surround and stereo
operation modes. The last pair of the surround speakers (channels 7 and 8) can also be dedicated as smallalternative stereo speakers when the primary
surround application is 5.1 or LCRS.
For flexibility, the front panel controls can be
removed and connected to the main unit in the
machine room, allowing full control to be maintained
from the listening position.
The unit itself is simple and easy to use, taking
advantage of a menu-driven 20x4 alphanumeric display and rotary encoder system, with important mode
keys illuminated for quick verification of their status.
This manual accompanies the unit, together with a
Setup Guide, which should be used when you are
first setting up and calibrating the unit.
For best results we recommend that you follow these
procedures regarding level and delay adjustment
whenever you make a substantial change to your
monitoring environment.
Installing the DS-M7.1
When you unpack the DS-M7.1, you should find, in
addition to this manual:
• A rack-mounting kit
• A standard power cable whose plug should match
the one for your region.
• A Setup Guide
• Warranty information, etc.
If any of these is missing, contact your TASCAM
distributor.
The DS-M7.1 is designed to fit into 3U of standard
19” rack space. Remove the feet before installing it
in a rack. We suggest that you leave at least 1U of
space above the unit to allow for cooling.
Do not install the unit in an enclosed space (bookcase, etc.).
Always check that the power requirements printed on
the rear panel of the unit match those available in
your working environment. If they do not, or if you
are in any doubt, consult a qualified electrician.
Temperature considerations The ambient
operating temperature should be between 5°C and
40°C (41°F and 104°F).
6 TASCAM DS-M7.1
Connections All connections to and from the DS-
M7.1 should be made and broken with the power
turned OFF.
1 – About the unit
Using the front panel as a remote control
When you use the front panel as a remote con-
unit
trol unit, you have the choice of using either the front
or rear 9-pin D-sub connector. If the DS-M7.1 is to
be installed in a machine room some distance from
the mixing location, we suggest using the rear con-
nector, where the cable may be routed more conveniently.
Follow the instructions given here (“Making up a
remote control cable” on page 38) when making up a
cable for use with the remote control. If you do not
follow these instructions, there is a risk of incorrect
operation, or even damage to the unit.

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 immediately 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 alternative 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 connectors and require appropriate “breakout” cables (consult 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.
