REPRODUCTION
Levelcontrol
[18]
The
function
of this

is
dependent
on
the setting of
switch
[21].
When
this
button
is
in
the released position, this control only
affects the
level
of
the
headphone.
lf
button
[21]
is locked
in
place. level
control [18] regulates the
output
of
the
line
as
well
as
the headphones. ln
stereo models. this
control
is
implemented
by
a
dual-operated potentiometer.
The inner control
is
assigned
to
channel
1,
the outer control to
channel 2.
The controls are
interconnected
with
a slip
friction clutch and thus can be indi-
vidually adjusted
for
balancing.
Headphone
jack
[19]

socket
for
one set of
headphones (impedance min. 200
ohms). The
output
level of
the headphone jack can

switch determines whether the output signal
is
selected
f
rom the tape or another source.
When
the
tape
is
not
moving, this
switch should
be
in
the
INPUT /
SYNC
position;dur-
ing
playback

position
ln
standard recording
operations,
either position may be selected (for
tape/ source
monitoring).
ln

SYNC
po-
sition.
UNCAL
button

[18].
Mode
selector
[22]
(Stereo models
only)
The reproduce mode
is
determined
by
the setting
of
the mode
selector.
(Switches all outputs and the VU-meters.)
Switch
positions:
STEREO
lndividual reproduction on both channels
MONO
Reproduction
is
intermixed
on both
channels
(check mono compatibility)
REVERSE
Same as STEREO,
however. channels are reversed
CHl
/CH2
The channel selected
will
be reproduced on both
outputs.
VU-meters
[23]
The
VU meters always indicate the
level available
at
the
output.
To
check the recording
level.
switch
OUTPUT
[20]
must
be set
to
the INPUT/ SYNC
position. ln mono models, the
lefr-hand
VU-
meter displays the input
level,
the right-hand VU-meter
the
out-
put
level.
RECORDING
(Although
two
sets of controls and connectors are available in
stereo models. each pair will
be described only once
because
the functions are
identical.)
Peak
level indicators
[24]
lf
these LEDs light
up
(even
if
only
brief ly),
modulation should
be
reduced
in
order to prevent distortion. The sensitivity
of
the LEDs
can be
adjusted
internally.
Recording preselector
REC
[25]
With this toggle switch, the desired recording channel can be
preselected
(switch position
READY). However,
the actual
re-
cording
operation must be initiated by simultaneously depres-
sing
the
PLAY
and
REC
keys. For
stereo recordings,
both
switches must be set to the READY
position.
For
mono
half track
recordings
or
in
SYNC mode, the unused channel should be
pro-
tected against unintentional
erasure by
setting the correspond-
ing
switch to the
SAFE
position. During recording operations,
these switches can be used neither
for
soft drop-in nor
for
soft
drop-out.
Recording
indicator lamp

This lamp lights
up
when
all
conditions for recording (including
tape transport) have been satisfied.
