4 – Connections
This section explains how to connect other equip-
ment to the DA-98 in a variety of situations. It is
not intended as a complete reference to the use of
the DA-98. See the appropriate sections for full
details of how these connectors are used.
WARNINGS
•
When making connections between the DA-98 and
other equipment, whether audio or control, both the DA-
98 and the other equipment must be turned off, other-
wise damage may be caused to the DA-98 and/or the
other equipment.
•
Only use TASCAM-supplied and TASCAM-approved
cables when making connections to the DA-98. Though
the cables and connectors may resemble computer
cables, they serve different purposes, and meet a differ-
ent set of specifications. The use of cables other than
TASCAM cables will at best cause the equipment to
work erratically, and at worst cause damage to the
equipment.
•
If the use of cables other than TASCAM cables causes
or results in damage, the warranty is voided.
4.1 Audio connections
Other audio equipment can be connected to the
DA-98 either using analog or digital interfaces.
4.1.1 Analog audio connections
All analog audio connections to the DA-98 are
made through 25-pin D-sub connectors (input sig-
nals through [47] and output signals through [48]).
This allows convenient and tidy cabling between
the DA-98 and other units such as the TASCAM
M-1600 series of mixing consoles.
It is not recommended that you make up your own
cables–consult your TASCAM dealer for avail-
ability of suitable ready-made cables (and see
15.1.5, "Cables"). However,we recognize that
every situation has its own unique features, and
there are occasions when a special cable must be
made.
Before starting to make the cable, we suggest you
contact your TASCAM dealer for full details of
cable specifications, etc.

The pinouts for both the
connectors are as follows:

All audio inputs are balanced and are rated at a
nominal +4dBu level.
The impedance of the inputs is 20k and that of
the outputs is 10 .
4.1.2 Digital audio connections
Digital audio input and output signals are carried
on the same 25-pin D-sub connector [45]. The sig-
nals are in TDIF-1 format.
To carry signals between a DA-98 and another
DTRS unit, use a PW-88D cable (1 meter long) or
a PW-88DL cable (5 meters long). You may also
use these cables to connect the DA-98 to other
TDIF-1-equipped devices.
If you need to connect the DA-98 to a digital
audio source using a different format, we recom-
mend the use of the following units:
•
TASCAM IF-88AE Interface Unit – converts
between the TDIF-1 and AES/EBU formats (8
channels). It also provides S-PDIF format con-
version facilities.
•
TASCAM IF-88SD Interface Unit – converts
between the TDIF-1 and SDIF-2 digital audio
formats.
4.2 Synchronization
connections
The DA-98 is equipped with sophisticated facili-
ties for control and synchronization with other
units. For full details of how to operate the DA-98
with other units, see 10, "Operations related to
timecode".
4.2.1 Analog timecode connections
The DA-98 can be synchronized to externally-
generated timecode and is also equipped with an
internal timecode generator. For full details of
