11 - Cascade
The TM-D4000 can be linked in a cascade with to up
to three other similar units, providing up to 128 mono
channels of input, together with eight stereo inputs.
The stereo outputs of all cascaded console are
summed. The eight output busses and the first four
Aux sends may also be summed, turning the chain of
TM-D4000 units into a modular, flexible recording
console. Note that Aux sends 5 and 6 are excluded
from the cascade, and hence can be used locally, with
the built-in effect processor of each cascaded unit—
this provides more flexibility in effect processing.
In the cascade, one unit is designated as the master
unit. All aux sends and busses that are being summed
are passed through to this master unit and are output
from the appropriate connectors on the master.
In addition, a summed output buss is always echoed
locally at the outputs of all consoles contributing to
the summed buss (this allows more than three MDM
units to be controlled by a cascade of TM-D4000s).
Individual busses and aux sends may be excluded
from the cascade summing, so that they are local to
the unit.
In addition to the signal summing described above,
the cascade function also links the following func-
tions of the cascaded units:
• soloing, for both IPS and PFL (5.4, “SOLO”)
• snapshot store and recall (8.1, “Snapshot memo-
ries”)
• option settings (3.3, “Option setup”)
• automation setup (automation documentation)
• automation mode (automation documentation)
11.1Cascade connections
As always, connections should be made with the
power to the units turned off.
WARNING
Only use the special TASCAM-supplied
cables (PW-4000CS) to make cascade con-
nections. Although computer cables may
appear similar, and may even be wired identi-
cally, the cables themselves have different
electrical characteristics, and damage may be
caused to the units if the wrong cables are
used.
If the use of cables other than these TASCAM
cables causes or results in damage, the war-
ranty is voided.
Slave units are numbered from 1 through 3. This
numbering is carried out as carried out below.
A cascade of TM-D4000 units is a “daisy-chain”; the
master unit should be at one end of the chain, with its
CASCADE OUT
connector
[78]
connected to the
CASCADE IN
of slave 1, whose
CASCADE OUT
connects to the
CASCADE IN
of slave 2, etc.
No termination is necessary, but all units in a cascade
connection must be turned on and selected as being
part of the cascade, even if they are not being used as
part of the chain. It is not possible to have a “dead”
unit in a chain or to have a unit in the physical cas-
cade chain which does not have the cascade function
selected.
1
If your units have not yet been configured for
use in a cascade, turn on and configure the
units that will be slaves first, and then turn
on and configure the unit that will act as the
cascade master.
2
On the first slave unit (connected to the mas-
ter unit) use the
DIGITAL I/O
CASCADE
screen to select the
SLAVE
1
ID for this unit.
3
Move the cursor to the
CASCADE ON/
OFF
button at the top of the screen, and
turn the cascade on for this unit:
4
Repeat this procedure for all the other slaves
in the chain, assigning the appropriate ID to
each slave.
5
Finally, set the master unit’s ID to MASTER,
and turn the cascade ON.
