Now you know how to select the signals you
want to send to the engineer’s control room or
phones. From there, these signals all pass
through the same level control:
CONTROL ROOM/SUBMIX
This knob controls the levels of both the
stereo
CONTROL ROOM outputs and
PHONES outputs . The control range is from
off through unity gain at the detent, with 10dB
of extra gain (when turned fully clockwise).
When
MAIN MIX is your SOURCE selec-
tion, those signals will now pass through two
level controls on the way to your control room
amp and phones — the
MAIN MIX knob and
this
CONTROL ROOM / SUBMIX knob. This
way, you can send a nice healthy level to the
MAIN OUTS (MAIN MIX knob at “U”), and a
quiet level to the control room or phones
(
CONTROL ROOM / SUBMIX knob wherever
you like it).
When
ALT 3-4 or TAPE is selected, or SOLO
is engaged,
CONTROL ROOM / SUBMIX knob
will be the only one controlling these levels
(channel controls not withstanding).
Whatever your selection, you can also use
the
CONTROL ROOM outputs for other appli-
cations. Its sound quality is just as impeccable
as the
MAIN OUTS. It can be used as addi-
tional
MAIN MIX output, which may sound
silly since there are already three, but this one
has its own level control. However, should you
do something like this, be sure that you do
not
engage a
SOLO switch, as that will interrupt
your
SOURCE selection.
PRE-FADER SOLO (PFL)
Engaging a channel’s
SOLO switch will
cause this dramatic turn of events: Any exist-
ing
SOURCE matrix selections will be replaced
by the
SOLO signal, appearing at the CON-
TROL ROOM outputs, PHONES outputs, and
at the right meter. The audible
SOLO levels
are then controlled by the
CONTROL ROOM /
SUBMIX knob. The SOLO levels appearing on
the right meter display
are not controlled by
anything — you wouldn’t want that. You want
to see the actual channel level on the meter
display regardless of how loud you’re listening.
“
PRE-FADER” SOLO means that the channel
signal is being tapped before the channel’s
GAIN knob (not really a fader in this case, but
we were afraid you’d laugh if we called it Pre-
Knob Solo). It does, however,obey
TRIM, LOW
CUT and EQ settings, making it the perfect tool
for quick inspections of suspect channels. The
channel’s
PAN and MUTE/ALT 3-4 settings have
no effect on the
SOLO signal.
Note: For stereo channels 5-12, the solo signal
is the mono sum of the left (odd-numbered)
and right (even-numbered) signals for that
channel strip.
WARNING:
PRE-FADER
SOLO taps the channel
signal before the
GAIN
knob. If you have a
channel’s
GAIN knob set
below “
U” (unity gain), SOLO won’t know
that, and will send a unity gain signal to
the
CONTROL ROOM, PHONES and meter
display. That may result in a startling level
boost at these outputs.
