TASCAM DR-680 1
Added functions
The following functions have been added with
rmware version 1.20.
1 Mid-side (MS) microphone decoding mode
2 GANG function
MS microphone decoding
mode
Setting the MS decoding mode
Select the
MS MODE
item on the
SYSTEM
menu to
open the
MS MODE
screen.
Set the decoding mode to use when connecting mid-
side microphones. Channel pairs 1-2, 3-4 and 5-6 can
each be set separately.
OFF (default value)
Recording and playback use the ordinary mode
(no mid-side decoding).
INPUT
Use this mode to decode while recording.
Playback uses the ordinary mode.
MONITOR
Use to monitor the output of mid-side
microphones with decoding while recording
without decoding.
Also use this with a take that was recorded
without decoding to decode it during playback.
In that case,
A.OUT SEL
should be set to
MIX
in
the
I/O
menu.
NOTE
The
MS MODE
screen settings cannot be changed
during recording or playback. Always stop the unit
(the transport icon should be ) before changing the
settings.
Connecting a mid-side microphone
When using this unit's mid-side decoding function,
connect the mid signal to the odd channel and the
side signal to the even channel in the pair. If you
connect them in reverse, correct decoding is not
possible.
For example, connect the mid signal to channel 3
and the side signal to channel 4.
Recording with mid-side decoding
1 On the
MS MODE
screen, set the decoding
mode to
INPUT
.
2 Press the MIX PAN key on the front panel to
open the
PAN
screen (pan pot adjustment
screen). Use the MS width control to adjust the
width of the mid-side signal pair.
Press one of the number (1-6) keys on the front
panel that corresponds to one of the mid-
side channels that was set to
INPUT
on the
MS MODE
screen. (For example, press 3 or 4 to
adjust paired channels 3 and 4.)
Use the VALUE dial to adjust the width of the
signal suitably in a 0–100 range. At 0, only the
mid channel is included in the stereo decoding.
As the value is increased, more of the side
channel is included in the stereo decoding. At
100, only the side channel is included. (The
default value is
0
.)
3 Press the MIX LEVEL key on the front panel
to open the
LEVEL
screen, and adjust the
decoder output.
Press one of the number (1-6) keys on the front
panel that corresponds to one of the mid-
side channels that was set to
INPUT
on the
MS MODE
screen. (For example, press 3 or 4 to
adjust paired channels 3 and 4.)

Use the VALUE dial to adjust the signal level
suitably in a 0–100 range. The lower the
number is, the lower the output level becomes
(default value:
100
).
NOTE
A take that was recorded without decoding (mid
•
and side channels recorded as is) can also be
decoded during playback by setting MS MODE
to
MONITOR
. When decoding during playback,
output will be of the stereo mix.
To record without decoding, set the
•
MS MODE
to
OFF or MONITOR .
If set to
•
MONITOR
, you can monitor the decoded
signal during recording.
GANG function
The GANG function allows you to adjust multiple
channels at the same time on the
TRIM
,
PAN
and
LEVEL
screens.
Set the range of channels to be ganged by pressing
the number keys for the channels at both ends of the
range at the same time.
For example, to gang channels 3–5, press the 3and 5
keys at the same time. When you do so, channels
3
-
5
will appear selected on the screen as shown in the
illustration below.
You can create multiple gangs of channels by setting
each gang separately. However, no channel can be
part of more than one gang.
When ganged, you can adjust parameters for the
ganged channels at the same time.
If the parameter setting for any of the ganged
channels reaches its maximum or minimum value,
turning the VALUE dial in the same direction will
not further increase or decrease the other channel
parameters.
If you press and hold the VALUE dial while multiple
channels are selected, the parameter values for all of
the ganged channels will be set to the lowest value
of the channels.
Any of the following actions will deactivate the GANG
function.
Press any key that corresponds to a channel that is
•
currently ganged.
Put the unit power in standby.
•
Activate or Deactivate MS decoding.
•
Use the INITIALIZE function.
•
When using the GANG function, the ganged channels
are the same on the
TRIM
,
PAN
and
LEVEL
screens.
However, at the
PAN
screen and the
LEVEL
screen,
a channel pair that is set to MS decoding cannot be
activated or deactivated the GANG function.
NOTE
You cannot gang channels that are set to use MS
•
decoding with channels that are not. However,
you can gang such channels separately.
You cannot gang channels that are set to use
•
dierent types of MS decoding.
When designating a range that includes multiple
•
channel pairs set to use MS decoding, only the
channels in the pair with the lowest number is
ganged.
If only one of the channels in a pair set to use MS
•
decoding is included in the range, none of the
channels will be ganged together.
