5 - Monitoring
The monitoring facilities on the TM-D4000 allow the
connection of both a control room (
CR
) and studio
(
STUDIO
) set of monitor systems as well as the con-
nection of a 2-track analog recorder through dedi-
cated connections (digital 2-track recorders may be
connected through the
D IN1
and
D IN2
inputs).
An integral talkback microphone is also provided, as
is a line-up oscillator. The talkback may be routed to
the slate or to the Aux 1-2 busses
5.1 CR and STUDIO
The
STUDIO
buss echoes the selection for the
CR
buss.
These connections are made through the appropri-
ately-labelled analog connectors on the top of the
front panel.
Note that these are professional-level (+4 dBu) bal-
anced outputs, and should be connected to an appro-
priately-equipped monitoring system.
A standard pair of stereo headphones may be con-
nected to the
PHONES
jack at the right of the con-
sole.
5.1.1 Monitor sources
The
MONITOR SELECT
keys (
AUX1
,
AUX2
,
AUX3
,
AUX4
,
AUX5
,
AUX6
,
D-IN1
,
D-IN2
,
2TR
and
STEREO
) are used to select the signals which are
routed through the monitoring system. These corre-
spond to the six Aux buss sends, the two digital
inputs, one of the two analog 2-track mastering
recorders (selected with the
2TR RTN 1/2
switch )
and the
STEREO OUT
.
Except when two Aux sends have been linked, only
one of these monitoring sources can be selected at
any one time.
The meters show the level of the selected monitor
source(s).
5.1.2 Adjusting volume
Use the
STUDIO/PHONES LEVEL
and
CR LEVEL
controls to adjust the the
STUDIO
and the
PHONES
levels together, or the
CR
level.
The
MONO
key (latching) puts the
CR
,
STUDIO
and
PHONES
output signals into monaural mode.
Use the
DIM
key to cut the
CR
level by 30dB when
necessary (the talkback key also dims the
CR
level).
The indicator lights when dimming is active.
5.1.3 Talkback
Push the latching
STUDIO
key under the
TB LEVEL
control to activate the talkback to the
STUDIO
out-
puts. The other
STUDIO
signals will be muted and
the control room outputs will be dimmed while talk-
back is carried out.
Adjust the level with the
TB LEVEL
control.
The
TO SLATE
and
TO AUX 1-2
keys in the monitor-
ing section allow the routing of the signal from the
integral talkback microphone to the slate (the stereo
output buss and the eight output busses) and the Aux
1/2 busses.
These are “smart” latching keys; in other words, if
pressed and released within half a second, they are
latching, and if pressed and held for more than half a
second, they are non-latching. They also dim the
CR
output level.
NOTE
Since this facility is available on the Aux 1-2
busses, which are also the only Aux busses
that can be made pre- or post-fader, you may
want to use these busses as the in-studio
headphone feeds if you require the artists to
listen to a different mix than that heard in the
control room. Of course, the
STUDIO
outputs
can also be used for this purpose, but they will
always mirror the control room feed.
5.1.4 Near-eld monitor s
Although the TM-D4000 is not tted with tw o sets of
CR outputs, it is possible to use the
STUDIO
buss as
a “near-eld” feed (especially if the Aux 1-2 busses
are used for in-studio talent cueing), and adjusting
the relative levels of the
CR
and
STUDIO
busses.
Alternatively, a system to switch between the two
different monitoring systems can be set up, fed from
the
CR
buss.
5.2 Meters
These meters show the level of the current signal
being monitored, as selected with the monitor select
keys. Note that the
2TR IN
analog signals cannot be
metered using these meters, however.
NOTE
When working with analog equipment, the
nominal analog signal level (4 dBu or
