IF-TAD Interface
IF-TAD Interface
The IF-TAD interface allows you to transfer up to eight channels
of digital audio data between digital audio devices equipped with a
TDIF-1 interface, and those equipped with an adat
face.
The units may be multitrack tape recorders, hard disk recorders,
digital mixing consoles fitted with the appropriate interfaces, D/A
converters, or any combination of these.
Either unit may act as the word clock master.
Data may be transferred in either direction, or in both directions
simultaneously.
A BNC connector provides a word clock signal derived from the
adat unit’s signals. When the adat unit is set to be the clock master,
this word clock signal can be used as the word clock source for the
TDIF-1 unit.
The LEDs on the IF-TAD give a continuous visual indication of
the status of the link between the units, as well as the power supplied to the IF-TAD.
The IF-TAD supports the standard sampling frequencies of
44.1 kHz and 48 kHz.
1
optical inter-
The IF-TAD supports a variety of word lengths, up to 24 bits.
When 20-bit or 24-bit data is transmitted to 16-bit units, rounding
or truncation is performed by the receiving device.

– TASCAM IF-TAD
IF-TAD Interface
WARNING
Note that you should always use genuine TASCAM
cables, or cables which have been approved for use
with TDIF-1 interfaces by TASCAM.
Although these cables appear similar to certain types
of computer cables and use similar connectors, the
cables themselves are very different, and the different
electrical characteristics of the cables can cause damage to the equipment connected with the wrong
cables.
If the use of cables other than TASCAM cab les causes
or results in damage, the warranty is voided.
4 TDIF-1 indicator
This indicator lights orange when a valid DTRS signal is recei ved
at the TDIF-1 connector.
If this indicator is not lit, it means that the unit has become disconnected, or is not switched on.
If the indicator is flashing, it means that both units (the TDIF-1
and the adat device) have been selected as the clock master, or
both have been selected as the clock slav e. Make sure that one unit
is selected as the word clock master, and the other as the word
clock slave.
5 adat IN and OUT connectors
Use these connectors to make the appropriate connections
(IF-TAD IN to the adat device’s optical OUT and the IF-TAD
OUT to the adat device’s optical IN). Use only optical audio
cables as recommended by the manufacturer of the adat device.
TASCAM IF-TAD –
11
IF-TAD Interface
6 adat indicator
This indicator will light orange when a valid adat signal is
received at the IN connector.
If the indicator is not lit, the connection may not be made correctly, or the adat device may be turned off.
If the indicator is flashing, it means that both units (the TDIF-1
and the adat device) have been selected as the clock master, or
both have been selected as the clock slav e. Make sure that one unit
is selected as the word clock master, and the other as the word
clock slave.
NOTE
If this indicator and the TDIF-1 indicator 4are both
flashing, this probably means that both the TDIF-1
device and the adat device have been selected as
clock sources. Rectify this situation by selecting one
device as a clock master and the other as a clock
slave.
12
– TASCAM IF-TAD
IF-TAD Interface
2 Operation
We suggest (though it is not absolutely necessary) that all equipment is turned off when making connections to and from the
IF-TAD.
WARNING
Since the word clock source will probably be changed
for one of the devices , causing an audible “glitch”, you
should turn down the levels of all monitoring equipment, to avoid damage to speaker systems, etc.
2.1 Word clock selection
As mentioned earlier, one, and only one, of the devices connected
to the IF-TAD must be acting as a word clock master. If both
devices are selected as a word clock master device, the indicators
4 and 6will flash, and the IF-TAD will not function.
Likewise, if neither is selected as a word clock master, there will
be no digital audio transfer possible (data will not be converted
using the IF-TAD).
Note that the WORD SYNC OUT connector also provides a clock
signal, based on the signals from the adat unit connected to the
IF-TAD, and this clock can be used to synchronize other units in
the system.
Refer to the units’ documentation for full details of how to set up
the units as word clock masters and slaves. A few examples of how
to use somecommonly-used units are given below (however your
best source of reference is always the documentation provided
with the unit):
TASCAM IF-TAD –
13
IF-TAD Interface
• On the TASCAM DA-98 and DA-88 DTRS recorders, the
CLOCK key is used to select between the different clock
sources available. If this is set to INT, the word clock is be
internally derived, or if a word clock is available at the BNC
WORD IN connector, the word clock is taken from there.
• On the TASCAM DA-38 DTRS recorder, the WORD
SYNC IN key is used to select between internal clocking
and an external word clock received at the WORD IN con-
nector.
• To set the TASCAM TM-D8000 digital mixing console
clock source, use the DIGITAL I/O ClOCK screen.
• To set the TASCAM TM-D1000 digital mixer clock source,
use the Master Clock Select sub-menu of the Option menu.
NOTE
As well as the word clock selection, you should also
make sure that the audio input source and output connectors for all units are set to the digital input receiving
data from the IF-TAD and the digital output transmitting data to it.
On the TASCAM DTRS series of recorders, this is
done using the DIGITAL IN key.
2.2 Problems which may occur
Clock loss on the adat unit may be corrected by changing the pitch
on the ADAT recorder away from standard pitch, and then returning it to standard pitch. This will force a re-locking of the clock.
Alternatively, you may have to turn off the adat recorder , w ait for a
short while and then turn it on again.
14
– TASCAM IF-TAD
IF-TAD Interface
2.3 Notes on word length
Some models of ADAT recorder record and play back digital data
at 20-bit resolution.
• On the TASCAM DA-38 and DA-98 recorders, if a 16-bit
input word length is selected, 20-bit data will be truncated to
the 16 bits recorded on the DTRS recorder. If 20-bit or 24-bit
is selected as the input word length, the 20-bit data will be
rounded to 16 bits, using the dither facilities built into the
DTRS recorder.
• On D A-88 DTRS recorders, the data is truncated (rather than
rounded) to 16-bit resolution.
• On the TM-D8000, use the OPTION page of the DIGITAL
I/O screen to set the word length.
You should be aware of differences in word length in the system,
and make the appropriate adjustment on the different units in the
system, referring to the unit’s documentation if necessary.
2.4 Note on metering
There are differences in the way that digital audio devices from
different manufacturers display levels on bargraph meters. In the
case of T ASCAM equipment, le vels o ver the digital full-scale le vel
are displayed as OVER. On other equipment, le v els within 1 dB or
2 dB of full-scale may be indicated as MAX on the topmost segment of the display.
Accordingly, when transferring data between devices, you may
notice that some louder portions of the material will cause red segments of the meter on one unit to light, bun not on the other unit.
This is usually not a problem, and simply reflects the way in which
different manufacturers choose to inform you of digital signal
levels.

through the optical interface. No dedicated word clock connections are required in this setup.
However, as described earlier, the ADAT LX20 may sometimes
experience problems at first with the word clock synchronization,
but using the PITCH UP and PITCH DOWN keys to change the
pitch away from standard, and then re-set to standard pitch will
usually re-lock the word synchronization (as described in 2.2,
"Problems which may occur").
