GENERAL OPERATION
The TM-D4000 is a very intuitive mixer to operate. All
mixing functions have dedicated buttons, allowing quick
navigation of common controls and views. Well thought
out displays on a large 320x240 LCD screen offer clear
information on all parameters in the mixer.
Controlling the Mixer
There are 19 motorized faders on the TM-D4000. Faders
are dedicated for the L/R output, as well as the 2 Stereo
Aux Returns. The remaining 16 faders flip through three
banks to control channels 1-16, 17-32, and the 8 busses
and 6 aux sends.
The standard conventions of digital mixers are followed
with the selection of a channel to appear in the mixing
section. However, you can also display global parameters.
For instance, instead of showing all the parameters on a
particular channel strip, you can display a specific
parameter from all channels.
To make the process even easier, the parameters
displayed in the screen will be shown in rows of 4 dials.
The rows will be controlled by the 4 dials just beneath
the screen. The arrow keys right by the dials control
which row you are working on. (The row you are working
on is highlighted.) If there are not 4 parameters to edit
in that screen, a blank dial will be shown in the screen
as a place holder to help keep clear the grid's relationship
with the dials.
The Channel Input Strip
Each channel on the TM-D4000 has a 4 band parametric
EQ, phase reverse, and dynamic processing. The EQ and
dynamics are incredibly flexible. The EQ section sounds
sweet enough to add a little extra sparkle to a particular
track, yet it's powerful enough to be used for corrective
measures or even
manhandling tracks for
wild EQ effects.
All four EQ bands offer a
wide ±15dB of gain. Each
band can sweep the entire
range from 31Hz to 19kHz,
so you don't have to worry
over which bands can
reach any particular part
of the audio spectrum. The high and low bands can also
act as shelf EQs, or can be assigned as a high pass filter
or a low pass filter.
A/B auditioning is revolutionary. Most mixers in this class
will offer an in/out switch for the EQ section. The
TM-D4000 goes far beyond that. In addition to the overall
EQ in/out control, each band has an in/out switch,
allowing you to audition the effect of each individual band.
If you don't like it, hit the "flat" button, and only that band
is flattened, allowing you to start over.
The dynamics on each channel can act as compressors,
or as expanders. Like the EQ, the impact of the dynamics
can be subtle or dramatic, depending on your needs.
There is also an in/out control for the dynamic section.

Aux, Buss, and Groups
The TM-D4000 has 6 aux sends. The first two can be
switched between pre or post fader for cue mix
applications. There are two dedicated aux returns with
all the EQ and compression that the input channel strip
has, plus the ability to feed another aux send.
There are 8 busses, which can be used for multitrack
feeds, or surround sound monitoring. There are also
direct output for the tracks, allowing more tracks to be
recorded simultaneously.
For channel grouping, there are 8 fader groups and 8
cut groups. Fader groups link numerous channels
together, allowing multiple channels to be adjusted
together. For example, all the mics on a drum kit could
be assigned to a group. Each mic would be adjusted
independently through their individual faders, but if the
fader group master was moved, then they all move in
accordance to the master. (This is similar to how
submixes were done on an analog console during
mixdown, except a fader group affects each individual
channel, rather than their summed output.)
Machine Control
Right on the top of the mixer is a convenient machine
control section. Large, "can't miss 'em" buttons for
standard transport controls let you keep your eyes on
the talent during overdubs. A large jog/shuttle wheel
helps make quick minor adjustments to time locations.
There is also a 10 locator memory built in.
