TASCAM IF-SM/DM Owner’s Manual

Soloing channels

This works with the same 

SHIFT

ed number 

keys as for muting (see Figure 2.3, 

SHIFTed 

number keys used for channel control

) as well 

as the cursor and 

ENTER

 key options. 

There are two solo options—one for an exclu-
sive solo mode, where only one channel at a 

time is active, and one for a mixed solo mode, 
where selected channels are active.

The on-screen solo marks are shown by an 

S

 

button, in the same way as the mute buttons are 
shown by an 

M

 (they invert when active, etc.).

Downmix on/off

Use the on-screen 

DOWN MIX

 button to turn 

downmixing on and off (as set up in the 

DOWN 

MIX

 option) — ignored when the alternative 

speaker switch, 2.1 switch or oscillator switch 
are on.

Bass management

Use the on-screen 

BASS MGT

 button to turn 

bass management on and off (as set up in the 

BASS MANAGEMENT

 option) — ignored when 

the alternative speaker switch, 2.1 switch or 
oscillator switch are on.

Alternative speakers

This routes the signal when downmixed to 
stereo, to the speakers connected to the LC 
and RC channels, which are not used in the 
surround patterns.

This allows the use of a pair of “large” stereo 
speakers together with smaller surround mon-
itors, without the need for repatching.

Naturally, downmix is not possible with this 
switch on.

Oscillator routing

Allows the routing of the mixer’s internal 
oscillator to the surround card outputs. 

When the oscillator is routed in this way, solo-
ing is automatically changed to exclusive 

soloing (it reverts to the previous setting when 
the oscillator is not routed in this way).

Note that downmix and bass management are 
not available when the oscillator is routed in 
this way.

To 2.1

When on and the current surround mode is 5.1 
or 6.1, this setting automatically overrides the 
current downmix setting (of course, downmix 
is not possible when this switch is on).

When this setting is deactivated, the original 
downmix and mode are restored, as is the 
mute status of the LFE channel.

USE ST-FADER

If you check “USE ST-FADER”, you can adjust 
the Monitor level settings by the Stereo fader.

SPL reference and level

Note that the 

SPL REFERENCE

 setting and moni-

tor level settings are made on this page. These 

are explained further in “MONITOR ALIGN-
MENT option” on page 14.
