receptacles, and the point where they exit from
the apparatus.
11 Only use attachments/accessories specified by
the manufacturer.
12 Use only with the cart, stand, tripod, bracket, or
table specified by the manufacturer, or sold with
the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to
avoid injury from tip-over.
13 Unplug this apparatus during lightning storms or
when unused for long periods of time.
14 Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has
been damaged in any way, such as power-supply
cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture,
does not operate normally, or has been dropped.
Do not expose this apparatus to drips or splashes.
•
Do not place any objects filled with liquids, such as
•
vases, on the apparatus.
Do not install this apparatus in a confined space
•
such as a book case or similar unit.
The apparatus draws nominal non-operating power
•
from the AC outlet with its POWER or STANDBY/
ON switch not in the ON position.
The apparatus should be located close enough
•
to the AC outlet so that you can easily grasp the
power cord plug at any time.
The mains plug is used as the disconnect device,
•
the disconnect device shall remain readily operable.

CAUTIONS ABOUT BATTERIES
This product uses batteries. Misuse of batteries could
cause a leak, rupture or other trouble. Always abide
by the following precautions when using batteries.
Never recharge non-rechargeable batteries. The
•
batteries could rupture or leak, causing fire or injury.
When installing batteries, pay attention to the polar-
•
ity indications (plus/minus (+/–) orientation), and
install them correctly in the battery compartment
as indicated. Putting them in backward could make
the batteries rupture or leak, causing fire, injury or
stains around them.
When you store or dispose of batteries, isolate their
•
terminals with insulating tape or similar to prevent them
from contacting other batteries or metallic objects.
When throwing used batteries away, follow the
•
disposal instructions indicated on the batteries and
the local disposal laws.
Do not use batteries other than those specified.
•
Do not mix and use new and old batteries or differ-
ent types of batteries together. The batteries could
rupture or leak, causing fire, injury or stains around
them.
Do not carry or store batteries together with small
•
metal objects. The batteries could short, causing
leak, rupture or other trouble.
Do not heat or disassemble batteries. Do not put
•
them in fire or water. Batteries could rupture or leak,
causing fire, injury or stains around them.
If the battery fluid leaks, wipe away any fluid on
•
the battery case before inserting new batteries. If
the battery fluid gets in an eye, it could cause loss
of eyesight. If fluid does enter an eye, wash it out
thoroughly with clean water without rubbing the eye
and then consult a doctor immediately. If the fluid
gets on a person’s body or clothing, it could cause
skin injuries or burns. If this should happen, wash
it off with clean water and then consult a doctor
immediately.
Remove the batteries if you do not plan to use
•
the unit for a long time. Batteries could rupture or
leak, causing fire, injury or stains around them. If
the battery fluid leaks, wipe away any fluid on the
battery compartment before inserting new batteries.

About SD cards
This unit uses SD cards for recording and playback.
A list of SD cards that have been tested with this unit
can be found on the TASCAM web site (www.tascam.
com).
Useofcardsthathavenotbeenveriedforusewith
this unit could result in the unit not functioning
properly.
Precautions for use
SD cards are delicate media. In order to avoid
damaging a card or the card slot, please take the
following precautions when handling them.
Do not leave in extremely hot or cold places.•
Do not leave them in extremely humid places.•
Do not let them get wet.•
Do not put things on top of them or twist them.•
Do not hit them.•
Beware of condensation
If the unit is moved from a cold to a warm place,
or used after a sudden temperature change, there
is a danger of condensation; vapor in the air could
condense on the internal mechanism, making correct
operation impossible. To prevent this, or if this occurs,
let the unit sit for one or two hours at the new room
temperature before using.

zLINE OUTPUTS jacks
These RCA pin jacks are unbalanced analog output
jacks. During the playback of multitrack files, the
sound previously recorded on each track is output
from these jacks.
During recording, the sound recorded to each track
is output from these jacks.
During the playback of the multi-track, according
to the unit setting, the stereo signal mixed by the
internal mixer can be output from output jacks 1/2,
3/4 or 5/6.
During the playback of a stereo track, the sound
of the stereo track is output through output jacks 1
and 2.
xDIGITAL/SYNC IN jack
This is a digital input jack. The signal input
through this jack can be recorded to tracks 5
and 6 or the stereo track. The unit automatically
determines whether the input signal is S/PDIF
(IEC60958-3) or AES3-2003/IEC60958-4 (AES/
EBU), which are both supported.
Transmission occurs at double speed when the
sampling frequency is 96 kHz and at quad speed
when 192 kHz.
When linking two of these units using the cascade
function, connect the DIGITAL/SYNC OUT jack of
the other DR-680 to this jack.
cDIGITAL/SYNC OUT jack
The stereo signal mixed by the internal mixer is
output from this jack.
According to the unit setting, the signal is output in
S/PDIF (IEC60958-3) or AES3-2003/IEC60958-4
(AES/EBU) format.
Transmission occurs at double speed when the
sampling frequency is 96 kHz and at quad speed
when 192 kHz.
When linking two of these units using the cascade
function, connect the DIGITAL/SYNC IN jack of the
other DR-680 to this jack.

Powering the unit
About the power supply
This unit can be powered by 8 AA batteries or the
included PS-1225L AC adaptor, which matches the
powerspecicationsofthisunit.
This unit can use alkaline or nickel-metal hydride AA
batteries.
Using AA batteries
Slide off the battery compartment cover on the bottom
panel of this unit, insert 8 AA batteries into the battery
compartment according to the +/– indications, and
close the compartment cover again.
When using AA batteries, set the battery type so
that the unit can accurately display the remaining
battery charge and determine the necessary minimum
remaining charge for operation. (See “Setting the
battery type” on page 46.)
CAUTION
Manganese AA batteries cannot be used.
•
This unit cannot recharge AA nickel-metal hydride
•
(NiMH) batteries. Use a commercially-available battery
recharger to recharge NiMH batteries.
NOTE
A great amount of power is required to provide
phantom power to a condenser microphone. If you use
a condenser microphone while running the unit on AA
batteries (NiMH rechargeable or alkaline), the operation
time will be greatly shortened. If you need to operate the
unit for a long time, use the AC adaptor.
Using the AC adaptor
Asshowninthegure,connecttheincludedPS-1225L
ACadaptor,whichconformstothespecicationsof
this unit, to the DC IN 12V jack.
AC outlet
DC plug
TASCAM
PS-1225L
Ahook(cordholder)toxthecordoftheACadaptor
is on the right side panel. Wrap the cord around the
hook when connecting it to prevent it from being
disconnected during use.
CAUTION
Use only the included PS-1225L AC adaptor, which
conforms to the specifications of this unit. Use of an
adaptor other than this model could cause malfunction,
fire or electric shock.
NOTE
If power is available from both batteries and the AC
adaptor, the power is supplied by the AC adaptor.
