2. TAPE TRANSPORT CONTROLS
2.1
Push
button controls
The
mechanical
control
of
the
tape
transport
is
carried
out by the
push buttons shown
in the
photo C.
The
buttons
19 and
20 control fast wind,
being
fast forward
and fast
reverse respectively.
Without fear
of
damage
of
the
tape
or
to
the transport
mechanism,
it
is possible
to
change
direction during
fast
wind,
by
virtue of the
smooth
braking and
precise
tape
control.
Playback is effected
by
depressing
button 21 which will
operate according
to
the
speed selected
by
switch
07.
Since
the
mechanism
is
solenoid operated,
only a
light
touch on
the button is
required.
On
depressing
the
stop
button (22], anv
previously
selected
function
will
be
automatically
disengaged.
The
use
of
button
23
will
be
dealt
with
later in the
section marked: "Recording
and
Monitoring".
2.2
Automatic
stop
The
REVOX
A77
is
provided
with
an
automatic stop
by
means
of a
photoelectric
cell. This
has
the effect of
dis-
engaging
any
selected
function
in the
same
manner
as
the
stop button
already
described above.
This
device
will
operatewhen
there
is
no
tape
between
the
lamp 36
and
the
photoelectric
cell
adjacent
to it. lt
should
be
noted
that
the
beam
of
light
is
sufficiently
intense
to
penetrate translucent
leader
or
splices
in
recorded
tape, which
will
result in
the
non-operation
of
the
machine.
Should
your
recorder
fail
to
function
at
any time upon
depressing
any
of
the
function
buttons,
we
would
advise
you
to
check
this
point.
2,3
Remote
control
The advanced
control circuitry
of
the
REVOX
A
77 permits
the
use
of full
remote
control,
as
shown
in photo
C.
The
connection
ofthe
remote
control
should
be made
to
socket
25.
lf
the
remote
control
fails
to
operate in any
function,
it
is
probable
that a fault
exists
at the
remote control
socket. Normally
this
socket is
fitted with
a
dummy
plug,
which
has
to
be
in
place before
the
machine can be
used,
it
is
as
well
to
check
that this
is plushed
firmly
home at
all
times.
