1–3
nals through the eight mono analog inputs, the two
stereo analog inputs and the two stereo digital inputs,
and outputting them to the stereo buss.
These interface cards are easy to install, and it is
therefore possible to keep a stock of different inter-
face cards, allowing the TM-D4000 to be used in dif-
ferent ways as needs dictate on different occasions.
Without any interface cards tted, the TM-D4000
provides eight monaural analog inputs and two pairs
of stereo analog inputs. These may be mixed to a ste-
reo pair of outputs, in either digital or analog format.
IF-TD4000 :
This interface card provides eight
channels of digital input/output in TDIF-1 format,
allowing devices such as the DTRS series to be con-
nected. In addition to the digital audio, this interface
card also provides a
REMOTE
OUT
connection,
allowing synchronization and control of the remote
DTRS recorder.
Note that when connecting a chain of DTRS units
using more than one IF-TD4000 card, etc. only one
of the DTRS units (the master unit) should be con-
nected directly to the TM-D4000 with the
REMOTE
connection. The other units should be “daisy-
chained” to the rst master unit.
IF-AE4000 :
This interface card provides eight
channels of digital audio input/output in 1992-3AES/
EBU professional format. The signals are connected
through a 25-pin ’D’-sub connector, and so a suitable
cable must be used in order to connect the AES/EBU
devices.
IF-LP4000 :
This interface card provides eight
channels of digital audio input/output in adat™ for-
mat. The links to external devices are made through
optical “lightpipe” connections, allowing the TM-
D4000 to be connected to any device supporting such
a compatible interface. A 9-pin ’D’-sub
SYNC OUT
connector is also provided, allowing full remote con-
trol of and word clock synchronization to the adat
device.
Note that when connecting a chain of adat units using
more than one IF-LP4000 card, etc. only one of the
DTRS units (the master unit) should be connected
directly to the TM-D4000 with the
SYNC OUT
con-
nection. The other units should be “daisy-chained” to
the master unit.
Also note than when an adat device is connected to
the IF-LP4000, both the IN and OUT connections
must be made, and they must be made to the same
unit to ensure clock stability across the system.
IF-AD4000 :
This interface card provides eight
channels of balanced analog input/output at profes-
sional (+4 dBu) levels. All conversion is carried out
at 24 bits of resolution. The signals are connected
through a 25-pin connector, and a suitable cable will
be necessary to connect the external analog devices.
1.3.1 Fitting the interface cards
1
Turn off the TM-D4000 and disconnect it
from the power supply. Disconnect all other
equipment connected to it.
WARNING
The above step is most important. If you do
not do this, there is a risk that you may cause
damage to the TM-D4000 as well as other
equipment.
2
Use the screwdriver to remove the blanking
panel from the slot into which you will t the
interface card. Keep the three retaining
screws in a safe place.
We suggest that you start from the top slot
(slot 1) and work downwards. Take care, if
you are removing a previously-tted inter -
face card, that you are removing the retain-
ing screws, and not the smaller screws which
x the card to the r ear plate . Also, if you are
removing a previously-tted card, use the
binding posts on the rear plate to help
remove the card.
3
Remove the interface card from the anti-
static protective bag.
