Control Room/Phones/Meters
CONTROL ROOM OUTPUTS
The 1/4" TRS stereo control room outputs can be used 
to run a separate sound system in a control room or a 
different zone. Connect these outputs to the line-level 
inputs of an amplifi er running passive studio monitors, 
or to the inputs of powered studio monitors.
The headphones play the same program material as 
the control room. The meters show the levels prior to 
the control room and phones level controls.
CONTROL ROOM/PHONES SOURCE
The source that plays in the control room,  
headphones, and meters is selected using the switches 
in the control room/phones source matrix:
• Main 
mix
• Tape
• Alt 
3-4 
• 
FW 1-2: The stereo FireWire 1-2 output from 
your computer
• 
A combination of all four above
If you do not select one of these, there will be no 
sound in the control room or phones, and no indication 
on the meters (unless a solo button is engaged).
Main Mix
Select main mix to listen to the main mix in the 
control room or headphones. The meters show the level 
after the main mix fader.
Tape
Select tape to listen to the RCA tape input in the 
control room or headphones. The meters show the level 
coming in from your tape or CD player. Press assign to 
main mix to play intermission music in your main mix.
Alt 3-4
Select alt 3-4 to listen to the alt 3-4 mix in the control 
room or headphones. This is a stereo mix of any  
channels that have their mute/alt 3-4 switch engaged. 
This can be used for cueing up sources prior to "going 
live," and for other useful reasons. The meters show the 
level of the alt 3-4 output.
FW 1-2
Select FW 1-2 to listen in the control room or  
headphones to the FireWire 1 and 2 audio streams   
coming from your computer. The meters will show the 
levels of the signals coming in from your computer.
Assign to Main Mix
Except for the main mix, whatever is selected as a 
source for your control room and phones can also be 
routed to the main mix by pressing this switch. The 
main mix does not play in the control room or phones if 
this switch is engaged.
SOLO
Whenever solo is engaged, all control room/ 
headphone source selections (main mix, alt 3-4, tape, 
and FireWire) are defeated, and you will only hear the 
soloed channel(s) in the headphones and control room. 
This gives you the opportunity to audition the channels 
before they are added to the main mix or alt 3-4 mix. 
The main mix continues to play, so the show can still go 
on during solo.
When a channel is soled, you can adjust the channel 
gain until your input source reaches the 0 dB LED in the 
right meter.
Solo signals reaching the headphones and control 
room are not affected by the channel level or main level, 
therefore turn down the phones level and control room 
level fi rst, as soloed channels may be loud.
