Marantz PROFESSIONAL PMD740 - Pitch Control

SYNC OUT
The
SYNC
OUT
knob
controls
the
level
at
which
sync
tones
are
output.
Various
kinds
of
synchronizrs
require
different
level
signals
at
their
input.
This
control
allows
you
to
match
the
PMD740’s
sync
output
level
with
the
input
level
of
your
synchronizer.
The
sync
tone
must
already
have
been
properly
recorded
on
track
4,
and
the
SYNC
switch
must
be
set
to
ON
before
this
control
has
any
effect.
In
most
cases,
the
SYNC
OUT
control
will
be
set
at
the
NORM
(hard
right)
position.
If
the
output
SYNC
signal
is
too
strong,
it
may
be
attenuated
by
turning
the
SYNC
knob
to
the
Left.
¢ NOTE
dbx
noise
reduction
may
interfere
with
using
a
synchronizer.
Test
your syne
system
with
dix
on,
and
if
you
encounter
problems,
leave
dbx
off
for
your
synchronized
recordings.
;
Also
note
that
recording
onto
Track
3
at
high
levels
while
synchronizing
may
interfere
with
the
SYNC
output.
If
you
are
recording
to
Track
3,
and
are
having
trouble
synchronizing,
try
recording
to
Track
3
at
a
lower
level.
METER SELECTOR
This
switch
selects
either
of
the
two
meter
modes.
With
the
switch
in
the
TRK
position,
met@rs
1-4
show
the
signal
recorded
on
their
respective
tracks.
In
L/R/CUE/EFFECT,
meters
1-4
show
the
following:
Meter 1: Left side of the STEREO BUS
Meter 2: Right side of the STEREO BUS
Meter 3: Master output level of the CUE BUS
Meter 4: Master output level of the EFFECTS BUS
@) VU METER
These
four
large
VU
meters
are
backlit
in
green
for
easy
viewing
from
a
distance
or
in
a
dark
studio.
When
a
track
enters
record
mode,
the
corresponding
meter
light
will
change
from
green
to
red,
to
indicate
recording.
When
the
track
is
no
longer
recording,
the
meter
changes
back
to
green.
Note
that
while
other
indicators
light
to
show
that
tracks
are
armed
or
that
the
machine
is
in
record-pause
mode,
the
VU
meter
color
does
not
change
until
the
transport
is
moving,
and
the
unit
is
ACTUALLY
RECORDING.
This
is
an
excellent
form
of
visual
feedback,
to
monitor
the
functioning
of
the
PMD740.
@2) TAPE CUE
These
controls
adjust
the
level
of
each
track
going
to
the
cue
bus.
This
signal
is
then
sent
to
the
CUE
OUT
on
the
rear
panel.
This
signal
may
also
be
sent
to
the
output
of
PHONES
2
if
the
PHONES
2
SELECTOR
switch
is
set
to
CUE.
@3) RECORD SELECT Switches and LEDs
These
switches
serve
two
functions.
First,
they
arm
and
disarm
each
track
for
recording—i.e.,
they
make
it
possible
or
impossible
to
record
on
a
track.
With
a
switch
in
the
SAFE
position,
the
track
is
SAFE
(or
“disarmed”).
This
means
that
you
cannot
accidentally
record
on
that
track.
This
is
particularly
important
when
you
finally
get
“the
perfect
take”
of
a
guitar
solo,
and
you
want
to
protect
yourself
from
mistakenly
recording
over
it.
When
a
switch
is
in
the
LEFT,
RIGHT,
or
DIRECT
positions,
it
is
considered
“armed”.
The
red
light
flashes
on
next
to
the
switch,
and
it
is
possible
to
record
onto
that track.
The
second
function
the
RECORD
SELECT
switches
serve,
is
to
designate
a
source
for
recording.
dbx NR
This
is
the
On/Off
switch
for
the
dbx
noise
reduction
system.
dbx
is
an
Encode/Decode
system
of
noise
reduction.
This
means
that
the
system
does
half
of
its
work
when
recording
the
tape
(encoding),
and
half
of
its
work
while
playing
the
encoded
tape
back
(decoding).
Therefore,
it
is
very
important
that
tapes
recorded
with
dbx
on,
be
played
back
with
dbx
on.
Also,
tapes
recorded
with
dbx
off
should
be
played
back
with
dbx
off.
@) PITCH CONTROL
This
slider
allows
+/-
10%
variation
in
tape
speed,
and
the
associated
pitch
changes.
This
can
be
used
to
correct
tunings
or
for
special
effects.
A
center
detente
allows
you
to
locate
the
“normal”
speed
by
feeling
for the center “click”.
