TASCAM DA-78HR
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
CLOCK
key so that
the
DIGITAL IN
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.
The
CLOCK
key is used to change between clock
sources, and should be set to
WORD
when synchro-
nizing to an external word clock (the
WORD
indica-
tor will light).
The
IN
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.
The
OUT
outputs word clock information provided
from the DA-78HR, while the
THRU,
to echoes the
signals received at
IN
.
Note that if the DA-78HR is connected to other
DTRS units, the
WORD SYNC
jacks do not need to
be connected between the DTRS units.
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 suitabl y-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
MIDI OUT
and
MIDI
THRU
. The
OUT
connector outputs signals which
originate from the DA-78HR. The
THRU
connector
echoes messages received at the
IN
.
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
TIME
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,
IN
,
OUT
and
THRU
, con-
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
REMOTE PUNCH
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
connector or to
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,
