27.4 Section Control Room 
In the section Control Room the menu Assign is used to define the Main Out which is used for 
listening in the studio. For this output the functions Dim, Recall, Mono, Talkback, External In 
and Mute FX are automatically applied. On the unit the VOLUME knob also follows this assign-
ment. 
Additionally the channel will be shifted from the Hardware 
Outputs into the Control Room section, and renamed Main. 
The same happens when assigning Main Out B or the 
Phones. The original name can be displayed by the function 
O-Names in the View Options at any time. 
Phones 1 to 4 will have Dim (set in Settings) and a special 
routing applied when Talkback is activated. Also putting them 
beside the Main Out increases the overview within the output 
section greatly. 
Note
: Phones 1 to 4 can be freely assigned in TotalMix FX. As 
the Phones output on the unit is hardwired to channels 7/8, 
selecting PH at the unit will always change the output level of 
channels 7/8, no matter which channels have been selected 
for Phones in TotalMix FX. 
Dim. The volume will be reduced by the amount set in the 
Settings dialog (F3). 
Recall. Sets the gain value defined in the Settings dialog. 
Speak. B. Switches playback from Main Out to Main Out B. The faders of the channels Main 
and Speaker B can be ganged via Link. 
Mono. Mixes left and right channel. Useful to check for mono compatibility and phase problems. 
Talkback. A click on this button will dim all signals on the Phones outputs by an amount set up 
in the Preferences dialog. At the same time the control room's microphone signal (source de-
fined in Preferences) is sent to the Phones. The microphone level is adjusted with the channel's 
input fader. 
External Input. Switches Main monitoring from the mix bus to the stereo input defined in the 
Settings dialog (F3). The relative volume of the stereo signal is adjusted there as well. 
Mute FX. Mutes Reverb and Echo on the 
Main Out, to hear the mix without those 
effects. 
Assign. Allows to define the Main Out, Main 
Out B (Speaker B), and up to four Phones 
outs. The choice is limited to ADAT 1/2, as 
at 192 kHz the other ADAT channels are not 
available anymore. The output for the Cue 
signal, which is usually Main, can also be 
set to one of the Phones outputs.
