The
REVOX
C270
tape
recorder
is
available
in
four
versions:
@
Stereo
half-track
(standard
unit
with
2mm
track
separation)
@
Stereo
half-track
RF
(broadcast
version
with
0.75
mm
track
separation)
@
Stereo
quarter-track
@
Mono
full
track
Only
one
type
of
recording
can
be
made
with
each
of
the
above
versions.
With
a
half-track
machine,
for
example,
stereo
recordings
can
be
made
only
in
one
tape
direction.
Stereo
half-track
refers
to
track
configurations
in
which
each
stereo
track
occupies
one
half
of
the
tape.
When
a
stereophonic
signal
sour-
ce
is
recorded
(e.g.
music
from
a
stereo
turn-
table),
both
tracks
are
always
recorded
con-
currently.
The
left-hand
channel
(CH1)
is
re-
corded
on
the
upper
track,
the
right-hand
channel
(CH
2)
on
the
lower
track.
If
mono
recordings
are
made
on
such
a
unit,
the
signal
should
always
be
recorded
simulta-
neously
on
both
tracks.
The
abbreviation
RF
designates
the
broadcast
version
of
the
stereo
half-track
machine.
The
only
difference
between
this
machine,
which
is
principally
intended
for
professional
users,
is
that
the
track
separation
(gap
between
the
two
tracks)
is
0.75
mm
rather
than
2mm.
The
increase
in
the
track
width
results
in
a
greater
dynamic
range
(range
between
peak
level
and
tape
hiss
at
low
level).
However,
the
fre-
quency
range
is
only
influenced
by
the
tape
speed
and
not
the
width
of
the
sound
track.
In
mono
full-track
models
the
entire
tape
width
is
available
for
recording
a
single
chan-
nel.
This
results
in
a
greater
dynamic
range
of
the
recording.
