how to use the DA-98 with timecode, see 10, “Operations related to timecode”.

The two XLR timecode connectors [37] carry bal- anced signals with the following polarity:

Pin # Connection

1Ground

2Hot

3Cold

However, unbalanced signals may be used, with only pins 1 and 2 connected.

	IN (balanced)	OUT (balanced)
Level	0.5 Vp-p to	2Vp-p
	10.0Vp-p
Impedance	> 10kΩ	< 100 Ω

The TIMECODE OUT connector either transmits internally-generated timecode or re-shaped or re- generated timecode echoed from the TIMECODE IN connector.

4.2.3 Word clock connections

This set of BNC connectors [39] is used to syn- chronize the DA-98 to other digital audio devices.

The front panel CLOCK switch (page 2-3) is used to change between clock sources, and should be set to WORD when synchronizing to an external word clock.

The IN jack should be connected to the WORD SYNC OUT of the digital audio device from which the DA-98 is to receive the synchronization clock.

Note the difference between the OUT and the THRU connectors. OUT is used to carry word clock signals generated by the DA-98, and THRU is used to echo the signals received at IN.

If the DA-98 is the last unit in the chain of video equipment, there is no need to terminate it, as this circuit is self-terminating.

Also note that if the DA-98 is connected to other

DTRS units, thejacks do not need to be connected between the DTRS units.

4.2.2 Video connections

This pair of BNC connectors [38] is used to pro- vide video frame reference clocking when the DA-98 is used with video equipment.

The front panel CLOCK switch [30] is used to change between clock sources, and should be set to VIDEO when synchronizing to video sync.

Connect the VIDEO IN connector of the DA-98 to the VIDEO OUT of a video unit. This signal should be a 1 Vp-p composite signal.

If other equipment (such as other DTRS units) also need the video frame reference clock, the sig-

nal received at theis echoed at the connector.

If the DA-98 is the last unit in the chain of video equipment, there is no need to terminate it, as this circuit is self-terminating.

For details of how the DA-98 can be synchronized to video frame information, see 11.1.1, “Video clocking”.

4.3 Control connections

4.3.1 RS-422 connector

This connector is used to connect the DA-98 to other controllers or editors which will control the DA-98 using the Sony P2 protocol, or a bus proto- col, such as that used by the TASCAM ES-61.

If you are in doubt about the compatibility of such a device, please consult TASCAM or your TAS- CAM dealer, who will be able to advise you.

The DA-98 can emulate (through software control accessed through menu 6) a number of devices for compatibility with almost any controller. See 11.1.2, “Emulation” for details.

Full details of control using this connector are given in 11.1, “Use with 9-pin external control”.

4.3.2MIDI connectors (IN , OUT and THRU)

These standard 5-pin DIN MIDI connectors [41] are used to carry MIDI Time Code (MTC) and MIDI Machine Control (MMC) information
