1 – Introduction
The IF-SM/DM card allows the connection of one or two surround monitoring systems. It provides flexible setup capabilities, routing, downmix capabilities, bass management, and monitor
setup, etc. from within the IF-SM/DM’s interface.
Installation
You should not install or remove cards yourself, but should refer installation to a qualified
TASCAM distributor. Otherwise, the warranty will be voided.
1Turn off the main unit and disconnect
it from the power supply. Disconnect
all other equipment connected to it.
WARNING
The above step is most important. If you do not
do this, there is a risk that you may cause damage
to the main unit as well as to other equipment.
2 Use a screwdriver to remove the blank-
ing panel from the slot into which you
will fit the interface card. Keep the
retaining screws in a safe place.
If you are installing more than one
card, we suggest that you start from the
top slot (slot 1) and work downwards.
Figure 1.1: Fitting the card
Ta ke care, if you are removing a previously-fitted interface card, that you
are removing the retaining screws, and
not the smaller screws which fix the
card to the rear plate. Also, if you are
removing a previously-fitted card, use
the binding posts on the rear plate to
help remove the card.
3 Remove the interface card from the
anti-static protective bag. Hold the
card by the edges, and insert it, component side upwards, into the slot.
Insert the card between the guide rails
and slide it all the way into the slot, as
shown. You may have to push firmly to
plug the card into the internal connector.
4 Locate the card into the connector
inside the main unit. Push the card
firmly, without forcing, so that the connector grips the end of the card.
TASCAM IF-SM/DM Owner’s Manual 3
1 – Introduction : Connections
A new unit’s card slot and/or new card
may be a little stiff. Make sure that the
card is pushed as far as it will go (so
that the card rear connector plate
touches the rear panel of the unit).
5 Use the screws supplied with the card
to attach the rear panel of the interface
card to the rear panel of the unit.
6 Repeat the installation process for all
the interface cards that you are fitting.
• When removing a card, unscrew the
five retaining screws and use the “pull
posts” on the rear panel of the card to
remove it from the unit. There are no
rules governing which interface cards
may be fitted in any of the slots, except
for the IF-FW card, which must be fitted in slot 1—any other interface card
may be fitted in any expansion slot.
Connections
The D-sub 25-pin connector allows the connection of up to eight balanced analog connections
at +4dBu levels (the impedance is 100Ω).

Suitable cables can be obtained from most
professional audio suppliers.
Monitor alignment
The card allows each channel to have an individual delay time set in milliseconds, as well
as a trim level.
This is set using the
screen, and the procedure is described later in
this manual (“MONITOR ALIGNMENT
option” on page 14).
