RECORDING
To make a recording,
set
the
selector switch
to
the
desired program
source
and
put
the
recorder
into
the
"record"
mode
of
operation.
With
the
MON I-
TOR
(TAPE/SOURCE) pushswitch in
the
"out
"
position,
the
original
program
source will be heard.
Depress
the
MONITOR (TAPE/SOURCE) pushswi-
tch
to
hear
the
"results"
of
the
recording while it is
in progress.
Caution: With
the
tape
recorder in
the
"record
"
mode, be careful
not
to
place
the
selector switch
in
the
"TAPE"
position while
the
MONITOR (
TAPE/SOURCE) pushswitch is
"out".
This feeds
the
recorder's
output
signals back
to
its
input
ter-
minals, establishing a reverberating loop. If
the
re-
corder's
playback level
happens
to
be
set
higher
than
its record level,
the
resulting
echo
or
"howl
"
will rapidly increase in
volume
level. This
won't
harm
the
recorder
or
receiver,
but
the
audible ef-
fect
from
the
loudspeakers can be annoying.
PLAYBACK
To
playa
tape
on (either) main
tape
recorder,
turn
the
selector switch to"TAPE," and
the
MONITOR
pushswitch
to
(desired) 1 or 2. To play an external
tape
recorder,
connect
its
outputs
to
the
dubbing
IN jack on
the
front
panel. When playing
either
main recorder,
make
sure nothing is plugged
into
the
dubbing
IN jack, or
the
main recorderts) out-
puts
will be internally
disconnected
in
the
receiver.
MAKING TWO RECORDINGS
SIMULTANEOUSLY
This can be
done
by following
these
two
methods:
1.
Connect
two
tape
recorders to
the
RECORD
1 and 2 jacks as
shown
in Fig. 7 . To
monitor
the
"main
1"
recorder, depress
both
the
MO-
NITOR (TAPE/SOURCE
and
1/2)
pushswit-
ches
and
to
monitor
the
"main
2"
recorder,
release
the
MON ITOR
(1/
2) pushswitch
only
.
2.
Connect
first
tape
recorder
to
the
RECORD 1
(or 2) jacks and
the
second
tape
recorder
to
the
dubbing
OUT
jack. To
monitor
the
first re-
corder, pull
the
plug
out
of
the
dubbing
IN
jack and depress
or
release
the
MON ITOR(1/2)
pushswitch with
the
MONITOR(TAPE/SOUR-
CE) pushswitch depressed. To
monitor
the
se-
cond

MONIT -
OR (TAPE/SOURCE) pushswitch.
RECORDING A LONG-DURATION PROGRAM
With
two
tape
recorders
connected
to
the
Model
2270
as shown in Figure
7,
a
continuous
re-
cording can be
made
without
losing
parts
of
the
program during reel changes.

General
Arrangement
of
Tape
Recorder
the
selector switch
set
to
the
desired program
source, and
the
MONITOR (TAPE/SOURCE) push-
switch in
the
"out"
position,
start
the
recording
on
the
main 1 recorder,
then
prepare
the
main 2
recorder
to
begin recording
before
the
main 1
recorder is
about
to
run
out
of
tape
. As soon
as
the
main 2
recorder
is
started,
ample time
will be available
to
reload
the
main 1 recorder
in
preparation
for
further
recording.
This
process
can be repeated indefinitely with
both
machines.
At
any
time
during
the
recording session,
the
recording can be
monitored
by depressing or
releasing
the
MONITOR
(1/2)
pushswitch with
MONITOR (TAPE/SOURCE) pushswitch depressed.
Using
the
input/output
and
control
facilities
of
the
Model
2270,
and
two
tape
recorders,
you
can
copy
and
edit
tapes
from
one
machine
to
the
other
.
The
general
arrangement
of
equipment
for
copying and editing is illustrated in Figure 7 .
COPYING AND EDITING
To
copy
from
the
main 1 recorder
to
the
main 2
recorder:
1. Depress
the
MONITOR
(1/2)
pushswitch.
2.
Set
the
selector switch
to
"TAPE"
and MO-
NITOR (TAPE/SOURCE) pushswitch to "
out"
position.
3.
Put
the
main 2
recorder
into
the
record
mode.
Note: In
this
case NO jack should be con-
nected
to
the
dubbing
IN jack on
the
front
panel.
