Step 5:
Step 6:
Thread a tape
as
directed under "Tape Threading.''
Set rhe machine
as
indicated in "Recording," immediately fol-
lowing.
The
ent
ire tape must be reeled onto the take-up reel, regardless
of
whether
or
not the recording
is
completed. FAST
-F
WD
can be used if
pr
ogram material does not use the entire tape.
Rem
ove the rake-up reel from the machine and turn
it
over.
Remove the turntable reel which is now free of rape.
Place the take-up reel
on
the curntable side.
Reversing the take-up reel after a recording run, places the tape in the
only position for
pr
ope
r threading from the turntable s
id
e; and also
o
ri
ents the st
ill
unrecorded half of rhc tape so that it
is
farthest from the
cape transport.
If
the rape had been
re
wound, the second run would
have erased the previous recording.
Refer to the steps in "Re
pr
oduce," following.
The
half track rape will
reproduce correctly only if oriemed
so
that the half of the
ra
pe desi
reJ
is
farthest from the rape transport surface.
In reproduce mode, afcer the entire rape has been r
ee
led onro rhe take-up
re
e
l,
reverse rhe
re
el and
pl
ace ir on rhe rurnrable side.
Previous
ly
recorded capes are erased automati
ca
lly
as new recordings
are made, eliminating the need for an erasure run because the tapes
first pass over the erase head whenever the machine
is
recording; bur
for rhe finest recording, it
is
recommend
eJ
that the rapes be tank erased.
Step 1:
Step 2:
Step 3:
Step
4:
Connect the program source equipment ( microphone, mixers,
etc.)
co
the
ap
propriate input.
P.la
ce the
MONITOR
SELECTOR switch on the
INPUT
function.
Place the
ON
-
OFF
toggle in the
ON
position.
Adjusr either the MIC REC LEVEL or the LINE REC LEVEL
concrol, depending
on
whether rhe
MICROPHONE
input
or
the LINE
INPUT
is
being
us
ed, so th
at
on the most incense
volume peaks of the program
to
be recorded, the v-u meter
ne
edle swings to approximately zero on the v-u scale.
It
is
unnecessary
co
scare
the cape morion in order
co
sec
the pro-
gram leve
l.
lf only one input
is
being used, turn
che
oc
her
REC LEVEL to zero.
Step
5:
Place rhe PLAY-REC control in the REC position
by
de
pr
ess-
ing the safety bucron ar the same rime rhe record position
is
selected.
Th
e transparent plastic button glows while rhe ma-
chine is in the record mode. This record safety fea
tur
e prevents
accidental erasure
of
previously recorded rapes.
Wh
en return-
ing
to the PLAY
or
rhe neutral position at rhe dot, the safety
butron
is
not used.
While
recording, a continuous comparison of the incoming program
and
ch
e reproduction on the
cap
e
ca
n be effected
by
mrning the
MON
I-
TOR
SELECTOR switch back and forth between
rh
e
INPUT
and
TAPE
positio
ns
and observing the v-u merer, or using headphones.
To
srop recording, return the PLAY- REC control ro neutral, marked
by a dot.

Step 5:
Thread a previously recorded cape on the machine.
Place the
ON
- OFF roggle in the
ON
position.
Place
the
PLAY- REC control in the PLAY position.
Place the
MONITOR
SELECTOR switch in the
TAPE
posi-
tion.
Adjust the reproduce level through the volume control
of
the
program source.
If there is no
output
, check the
MONITOR
SELECTOR
switch position.
When
the machine
is
in the play mode,
the
MONITOR
SELECTOR switch muse be in the
TAPE
positio
n.
OUTPUT
can be monirored wirh the head
ph
on
es
plugged into the jack on the front pane
l.
To
rewind or move tape forward rapidly, place
REWIND-
FAST
FWD
switch in the position desired.
The
tape moves
at
800 feet per
minute in either direction, and can be shuttled back and forth between
REWIND
and FAST
FWD
positions without waiting for the cape
co
decelerate
or
srop.
Th
us, cueing and editing
ca
n be accomplished
ac
high speed with no danger
of
tape breakage.
Th
e
REWIND
- FAST
FWD
and
PLAY-REC
controls are mechani-
cally interlocked, making impossible the switching
of
either control
unless the other
is
in neutral.
This
safety feature guards against cape
breakage which would occur if the machine were switched directly from
either
of
the high speed modes ro PLAY or REC positio
n.
CAUTION
Always return
REWIND-FA
ST
FWD
control
co
neutral
position,
and wait
tii
tape motion stops before switching to
PLAY
or
REC. Placing
se
lecror controls
on
PLAY
or
REC
while
tap
e
is
in motion will cause stretched or broken tape.
To
erase a previously recorded cape when no new reproduction
is
de-
sired,
turn
both
of
the R
EC
LEVEL controls
ro
zero and run the tape
in the record mode.
Because microphone and line recording channels are independent, each
governed by its own level control, sim
ul
taneous recording from rwo
sources can be made with
out
an external mixer.
For example, singing, voice announcements
or
inscrumencal accom-
paniment
ca
n be dubbed into a program being recorded from a con-
solette
or
other tape recorder.
To
effect chis, connect the program source
equipment co the LINE
INPUT
conneccor and a microphone
co
the
MICRO
PHONE
connecror. Adjust both the
MICROPHONE
REC
LEVEL and LINE REC LEVEL controls for desired balance between
the two programs.
