Talkback, etc.
The internal talkback microphone is located above
the meters. The sensitivity of the microphone is
adjusted using the
T/B control next to the micro-
phone.
The
TO SLATE
and
TO STUDIO
keys are both
“smart keys”. When active, they route the talkback
microphone to the busses and/or aux sends as
selected below, and to the studio respectively, and
dim the control room outputs.
The
MONO
key (also a “smart key”) provides mono
control room monitoring, combining the left and
right signals into one mono signal.
Talkback source
However, note that the internal
talkback microphone does not have to be used as the
talkback source. Any one of the mic/line sources can
be selected as a communication source (for example,
a boundary field microphone situated in a large con-
trol room can allow comments from a production
group to be routed to the artistes in the studio).
Select the talkback source ( T/B SOURCE ) in the MONI-
TOR OSC/COM screen:
Use the cursor to navigate to this field, the dial to
make the selection between
INT T/B MIC
(internal
microphone) and MIC/LINE 1 through 16 . Press
ENTER
to confirm the setting.
Slate definition
The COMMUNICATION fields
allow you to choose the busses and aux sends which
will act as the “slate” when the
TO SLATE
key is
enabled for sending talkback. Any combination of
busses, aux sends and the stereo buss can be selected
(cursor keys and
ENTER
key) as slate destination.
Linking of busses and aux sends has no effect on this
screen.
Oscillator and noise generator
In order to help with signal tracing, the setting of
SPLs, etc., the DM-3200 provides an internal tone/
noise generator.
The POD 1 switch turns the generator on and off.
Use POD 2 to set the type of generator: either a sine-
wave oscillator (
SINE
), a white noise generator
( WHITE ), or a pink noise generator ( PINK ).
POD 3 sets the frequency if the sine wave oscillator
has been selected. There are four choices:
100Hz
,
440Hz (standard tuning A), 1kHz and 10kHz .
POD 4 sets the level from –36dBFS to 0 dBFS in 0.5 dB
steps. Remember that –16 dBFS is the nominal level,
so you can use this setting when setting up SPLs, etc.
for your monitoring system.
Oscillator destination
Use the OSCILLATOR fields
(cursor keys and
ENTER
key) to route the generator
fields to any combination of busses, aux sends or the
stereo buss. This is an extremely useful “patch-free”
method of signal tracing.
