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 dam-
age to the equipment connected with the wrong 
cables.
If the use of cables other than TASCAM cables...

6adat 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 cor-
rectly, or the adat device may be turned off.
If the indicator is ßashing, 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 slave. Make sure that one unit 
is selected as the word clock master, and the other...

2 Operation
We suggest (though it is not absolutely necessary) that all equip-
ment 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 ÒglitchÓ, you 
should turn down the levels of all monitoring equip-
ment, to avoid damage to speaker systems, etc.

¥ 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.

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 DA-88 DTRS recorders, the...

3 Examples
The following provide examples of simple connections which use 
the IF-TAD to convert between digital audio formats.
3.1 DTRS and ADAT recorders
This simple example allows data transfer between a DTRS 
recorder and an ADAT multitrack recorder:
Note that here the ADAT recorder acts as the word clock master, 
and the DTRS recorder takes its clock reference from the IF-TAD 
through the IF-TADÕs WORD SYNC OUT connector.
3.2 TASCAM digital mixer and ADAT LX20...

through the optical interface. No dedicated word clock connec-
tions are required in this setup.
However, as described earlier, the ADAT LX20 may sometimes 
experience problems at Þrst 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).
