1 - Introduction—Expansion cards

Hold the card by the edges, and insert it,
component side upwards, into the slot.
5
Locate the card into the connector inside the
TM-D4000. Push the card firmly, without
forcing, so that the connector grips the end of
the card. A new TM-D4000 and/or new card
may be a little stiff. Make sure that the card
is pushed as far as it will go (so that the card
rear connector plate touches the rear panel
of the TM-D4000).
6
Use the three blanking plate screws to attach
the rear panel of the interface card to the
rear panel of the TM-D4000.
Repeat this process for all the interface cards
that you are fitting.
When removing a card, unscrew the three retaining
screws and use the “pull posts” on the rear panel of
the card to remove it from the TM-D4000.
There are no rules governing which interface cards
may be fitted in any of the three slots—any interface
card may be fitted in any expansion slot. However,
the following points should be noted.
1.3.2 Input channel numbering
Regardless of the type of interface card fitted, and the
expansion slots in which any cards are fitted, the
numbering of the input channels is always as follows:
These assignments are fixed, and cannot be changed,
except that channels 5 through 8 and 13 through 16
can be assigned to the digital inputs (SPDIF or AES/
EBU).
It is important to note that there are no dedicated tape
return channels. Furthermore, because of this, every
channel, no matter what its current signal source, is
provided with the same full facilities of equalization,
dynamic processing, etc., and all channels may be
routed to the output busses in an identical manner
(direct outs are only possible for input channels 1
through 16, though).
1.3.3 Output busses
All eight output busses are routed simultaneously in
parallel to the appropriately-numbered outputs of all
three slots (or as many as are filled with expansion
cards). If all three slots are filled, output buss 1 is
therefore output to output channel 1 of the cards in
slot 1, slot 2 and slot 3.
It is therefore possible to record up to 24 tracks
simultaneously, but when the output busses only are
used, only eight different signals are output. If, for
instance, a 24-track recorder is connected to the TM-
D4000 using three IF-AE4000 cards, the signal of
output buss 3 will be recorded on tracks 3, 11 and 19,
for example.
However, you can use the “direct out” function of
input channels 1 through 16, which will allow simul-
taneous recording of these sixteen inputs to output
busses 17 through 32 (slots 2 and 3), overriding any
signals which have been taken from the output bus-
ses.
At the same time, any inputs from slots 2 and 3
(channels 17 through 32) can be routed through the
output busses, which will be output through slot 1
(outputs 1 through 8).
Before you start recording, make sure that you have
the correct interface cards for your setup, so that you
can interface the TM-D4000 to the other equipment
in your setup.
1.3.4 Direct out
As explained later in this manual, the signals from
input channels 1 through 8 (the integral analog
inputs) and channels 9 through 16 (the first expan-
sion slot) can be assigned to be sent as direct out,
rather than to an output buss.
In this case, to determine the number of the output
channel, add 16 to the input channel. Input channel 1
is therefore routed to output channel 17 (the first
channel in the second interface slot), input channel 9
to output channel 25 (the first channel in the third
interface slot) etc. If no interface cards are fitted in
