FEATURES
OF
THE CASSETTE
DECK REVOX
B71O
To obtain
maximum stability. the
Revox cas-
sette
deck
has
been builtwith
an all-metal
cast
tape
transporl chassis.
Parts subject
to wear
have
been
reduced to an absolute
minimum.
On
the
8710; neither belts,
slip clutches,
fric-
tion wheels
nor mechanical brakes
are used.
ln
place
of a conventional
dual
capstan drive,
the shockmounted
4-motor
tape
transport
system
features
two separate
direct
drive
motors which are
controlled
individually
by a
common
qua
rtz frequency.
The heads are
positioned
electromagnetical-
ly To
prevent
jerking
motions,
the
movable
headblock assembly
is
pneumatically
damp-
ened.
The complete
cassette deck
has
been
de-
signed
for
heavy-duty
use over many
years.
The built-in
microprocessor and control
logic
provides
a
high level of operating conve-
nience and
prevents
operating errors
which
could damage the
machine
or the tapes.
The microprocessor accepts data
regarding
the beginning
and end of a tape section
for re-
petitive
play
back.
The tape counter can also
be used
forvarious timerfunctions.
A
receiver
(8780
equipped
with the Remote Control
Board) connected
to the
cassette
deck
can be
switched
remotely,
in
parallel
with the cas-
sette
deck. These features
make
it
possible
to
record
an
interesting
radio
broadcast
even
when
the user
is absent.
