3 - Connections

3.1.4 SPDIF connectors

The coaxial RCA digital audio connectors on the rear
panel allow connection of an SPDIF-equipped device
(e.g. a DAT recorder).
This digital unit should be used as a clock source if
data is to be read from it
When synchronizing to the signal received at the
COAXIAL DIGITAL IN
, set the
DIGITAL IN
the indicator lights.

3.2 Synchronization connections

The DA-78HR has facilities for control and synchro-
nization with other units. For full details of how to
operate the DA-78HR with other units, see 8, "Syn-
chronization with other DTRS units" and 9, "Opera-
tions related to timecode".

3.2.1 Word clock connections

This set of BNC connectors is used to synchronize
the DA-78HR to other digital audio devices.
CLOCK
The key is used to change between clock
sources, and should be set to
nizing to an external word clock (the
tor will light).
IN
The jack should be connected to the WORD
SYNC OUT of the digital audio device from which
the DA-78HR is to receive the synchronization clock.
OUT
The outputs word clock information provided
from the DA-78HR, while the
signals received at IN .
Note that if the DA-78HR is connected to other
WORD SYNC
DTRS units, the

3.2.2 MIDI connectors (IN , OUT and
THRU)
These standard 5-pin DIN MIDI connectors are used
to carry MIDI Time Code (MTC) and MIDI Machine
Control (MMC) information between the DA-78HR
and other suitably-equipped units (for instance,
sequencers capable of being synchronized to MTC,
and capable of transmitting MMC commands).
The MIDI parameters are set through the menu
system (see 10, "MIDI control").
Note the difference between
THRU . The OUT connector outputs signals which
originate from the DA-78HR. The

3.2.3 Timecode connections

The DA-78HR can be synchronized to externally-
generated timecode and is also equipped with an
internal timecode generator.
SMPTE/EBU timecode can be received at the
CODE IN RCA jack, and can be transmitted from the
TIME CODE OUT RCA jack.
See 9, "Operations related to timecode" for details.

3.2.4 MIDI timecode connections

The three MIDI connectors,
form to the MIDI standards for such connectors.
3.3 Connection to other TASCAM
units
By a "TASCAM unit", we mean another DA-78HR,
a DA-98, DA-88 or a DA-38 unit, or an optional
remote control unit, which may also be connected in
a "chain" with multiple DTRS units.

3.3.1 REMOTE IN

This jack on the rear panel can be used to connect a
remote control unit such as RC-808 remote control
unit.
Basic control can be carried out using this unit, but
more advanced operations will not be possible.

3.3.2 Footswitch

A footswitch such as the optional TASCAM RC-30P
footswitch can be connected to the
IN/OUT
jack on the rear panel.
This footswitch allows hands-free punch-in and
punch-out.
When a track or track is armed, and the unit is in play
mode, pressing the footswitch once will drop the unit
into record mode, and pressing it again will drop it
back into play mode.
The footswitch, rather than the transport keys, can
also be used to set punch points, as described in 5.6,
"Punch-in and punch-out".

3.3.3 Multiple DTRS units

Use a TASCAM PW-88S cable when connecting
other units to the REMOTE/SYNC IN
the SYNC OUT connector.
This synchronization cable will carry the internal
synchronization code and the transport signals, etc.
There is no need to make any other connections,
