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–consultyour 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.

Section 4 – Connections

The pinouts for both the ANALOG OUTPUT and

INPUT connectors are as follows:

where G=ground, H=”hot” (+) and C=”cold” (–).

All audio inputs are balanced and are rated at a nominal +4dBu level.

The impedance of the inputs is 20kΩ and that of the outputs is 10Ω.

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”.

4.2.1Analog 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
