2 – Using the card : ROUTING option

  TASCAM IF-SM/DM Owner’s Manual

Notes on other hardware controls

MONO key 

When the card is being used for 

monitoring in surround mode, the 

MONO

 key 

on the control surface is used to turn downmix 
on and off (as set up in 

DOWN MIX

).

DIM key 

The 

DIM

 key on the control sur-

face can be used in the usual way to dim the 
outputs from the card. The dimming level is 
set in the mixer.

ROUTING option

There are two main functions here. The first 
allows you to set up the monitoring keys, and 

the second allows assignment of the outputs 
to the different channels.

Figure 2.4: ROUTING option screen

Monitoring keys

The three assignable monitor selection hard-
ware keys in the mixer’s monitoring section 
can be set here. 

The following can be selected as monitor 
sources (stereo):

• Individual Aux busses
• Pairs of Aux busses
• Individual busses
• Pairs of busses
• Digital inputs (1 or 2)
• 2 TR analog inputs
• The TDIF signals (1 through 3)

• The ADAT signal
• The signal of any card in a slot other than 

the surround monitor card

In LRCS, 5.1 or 6.1 modes:

• Surround buss 1–8
• Surround buss 9–16
• Digital inputs (1 or 2)
• The TDIF signals (1 through 3)
• The ADAT signal
• The signal of any card in a slot other than 

the surround monitor card

Output routing

When a “Line” is referred to in this screen, it is 
referring to the analog output line from the IF-
SM/DM card (as shown in Table 1.2, 

Pin 

assignments of the IF-SM/DM analog outputs

)..

The lines can be assigned to the different chan-
nels used by the surround pattern currently 
selected, differing from the default assignments 
made when the surround pattern is selected.

These channels are shown as 

L, R, C

, etc. If a 

line output is unused by the pattern, as output 
8 is unused in Figure 2.4, 

ROUTING option 

screen

, it is shown with the number and 

dashes (

-8-

).

Note that loopback routing is not possible in 
this case (see Figure 3.2, 

Level diagram

).
