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.
