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 L-R mix
•
Stereo tape inputs
•
Sub 1-2 / Sub 3-4
•
FW 1-2: The stereo FireWire 1-2 output from
your computer
•
A combination of all four above
Select one or more of these, or 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 levels
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.
Sub 1-2/3-4
Select sub 1-2 / 3-4 to listen to the sub 1-2 / 3-4 mix in
the control room or headphones. The meters show the
levels after the subs faders.
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.
