a
small woofer beyond
its safe
excursion
limits,
causing
its
voice-coil to clatter
against
the magnet
backplate.
As
long
as
the speaker sounds good
it
probably
is OK; but
distorted
or unmusical sounds, such
as
clattering
noises, are a sign
ol distress
in
a
woofer.
Be
alert, also, for
signs
ol
acoustic
feedback
(in which
the low-frequency vibrations from the speakers
are picked
up by
the record-playing stylus and are re-amplified). lf
you encounter
a
sustained low-frequency
roar, or
frequent
groove-jumping, immediately turn
down
the
Volume and
switch
off
the BASS
EQ until
a more
nearly
vibration-free
mounting
for the turntable
is found.

TAPE MONITOR.
When
this button
is
pressed
it
overrides the other lnput Selector
buttons
and
lets
you
hear
the playback signal from your tape recorder
(or any
other
device connected to the
PLAY
input
jacks
on
the
rear panel
of the
7120).
ll you
have a
signal-processing accessory
(such as a
graphic equalizer or dynamic
expander) con-
nected
to
the TAPE RECORD/PLAY
jacks,
pressing TAPE
allows you to
hear
the processed
signal.
CAUTION:
lf
you have
nothing
connected
to
the
RE-
CORD/PLAYjacks, or
have
a
tape
deck
connected
but not
running, then
when
you
press TAPE
you will
hear nothing
but
silence-regardless
of
what
other
selector
buttons you
may press!
To
disengage
the Tape Monitor
circuit
and
restore
the
normal
signal
path, press the TAPE button again
and release
it.
The standard
purpose
ol
the TAPE MONITOR
is
to
allow you
to
listen
to
recorded
tapes,
and also
to
check on
tape recordings
as
they
are
being made.
lf
you
have
a
three-head tape deck that
allows
off-the-tape
monitoring
during recording, engaging
the TAPE MONITOR
switches
on
both lhe
7120
and the
tape deck will
let
you
hear the
playback signal from the tape immediately after
it is re-
corded,
so
that you can
check
on
its quality.
To
make
tape recordings
on a recorder attached to
the
7120's RECORD/PLAY
jacks, simply
use
the
INPUT SELEC-
TOR
buttons to select the
program source
that
you
want
to
record
lrom
(PHONO,
FM,
etc.). The
recording
will
not be
affected
by any
of the controls
located to
the left of
the
INPUT SELECTOR;
thus you
may
vary the volume,
balance,
tone
controls, tape
monitor
switch,
etc.,
without
altering the
recording that is being
made.
COpflNG
TAPES:
lf you
want
to
copy a
recording
from one tape deck to
another,
connect the
playback cable
from
the "source" deck
(the machine
containing
the tape to
be
copied)
to
the
7120's
AUXiliary
inputs, and
connect the
"copying" or "dubbing"
recorder
to the
7120's
RECORD/
PLAY
jacks.
Press
the
AUX
button
in
the
lnput
Selector
group
to
hear
the
source
tape
and
feed
its
signal
to the
copying
recorder. lf you
then
press
the
TAPE MONITOR,
you will
hear
the chosen signal after
it has passed through
the recorder's electronics.
10.
INPUT SELECTOR (AUX,
PHONO,
AM,
FM).
These interlocked switches select the
input signal
for
the
7120.
This
is
the
signal
that you will
hear,
assuming that
the
TAPE MONITOR is
disengaged.
The
selected
input signal
will also
be
fed
out
through the
RECORD
jacks for
tape
recording or signal processing,
regardless
of the setting
of
the TAPE MONITOR switch.
11.
TUNING PRE-SETS.
You
can store
the frequencies
of ten favorite stations (5
FM
and
5
AM)
in
these
pre-sets
and
then tune them
instantly
just
by pressing
the
appro-
priate
button.
The pre-sets preserve their frequency
assignments
when
the receiver
is
switched
off
or
unplugged from
the
AC
wall socket, for a
period
of
up to
two
weeks.
Thus
you can
re-arrange your stereo system, or
move
the
receiver from
roorn
to
room,
without
losing
the
pre-set
frequencies.
But if
you
leave
the receiver switched
oft
for
a month
or
more, you
may have
to re-program
the
tuning
pre-sets.
12.
UP/DOWN
TUNING.
The
tuning control
is a
"rocker" switch that
allows you
to tune
up and down the AM
or
FM
radio spectrum.
Depress
the
right-hand section of
the switch
in
order
to tune
to higher frequencies,
and
the left-hand
section
to
tune
to
lower Irequencies.
When the
TUNING button
is
pressed
momentarily, the
tuned frequency
is
shilted
up
or down
by one
step. (ln
North
America the
size
of this tuning step is
10
kHz on the AM
band. ln
Europe and
elsewhere
the
tuning step
is
9
kHz on
AM.)
Each time
the TUNING button
is
tapped,
the
tuned
frequency
will
shift
up
or down
by
this increment,
as shown
on
the digital frequency
display.
lf the TUNING button
is held down with
continuous
pressure rather
than
just tapped,
the
tuning
pauses briefly
and
then scans rapidly
up or
down
in frequency.
Thus, to manually tune
a
station, the procedure
is
to
press
continuously
on either side
of
the
TUNING button
until
the receiver's frequency
is
close
to
the desired
broadcast
frequency, and
then fine-tune
by
tapping
the
TUNING
button
until
the digital frequency display
exactly matches
the
sta-
tion's broadcast frequency as listed
in a
local
newspaper
or broadcasting
guide.
13.
MEMORY
ENTER.
This button
is used
to enter
the
frequencies
of
your favorite stations
in
the receiver's
ten
memory pre-sets (five pre-sets
on
the
FM band and
five
pre-sets
on
AM). The procedure
is as follows.
(1)
Decide
which station you want to
assign
to
each
pre-set.
On
each
band
you
may arrange
the stations
in
any
order that you find convenient
(or easy
to
remember):
alphabetical
(1:WABC,
2:WCBS, 3:WNYC
. . .), numer-
ical
(1
:
BBC1,
2:
BBC2,
.
.
. ),
or
in
order of
increasing
frequency
(1
:89.2 2:90.9, 3:95.3,
etc). ll you
are not
certain
ol
the
exact
frequencies
ol
the stations,
check
the
station/frequency directory
in
a
local newspaper
or
broad-
casting
guide.
(2)
Select
the AM or
FM
band,
as
appropriate.
Using
the
TUNING
rocker, manually tune
to
the
first station
on
your
list. Press
ENTER,
then press
Pre-set #1
to
store the
lirst
station. After you press
ENTER
you will
have
at
least ten
seconds
during
which you
can
store
the
tuned station
in
one of the pre-sets,
before
the
ENTEH mode automatically
de-activates.
Only
one
pre-set
can
be set at one time.
(3)
Manually
tune to the
second
station
on
your
list.
Press ENTER
button
and
then press
Pre-set
#2
to store the
second
station.
(4)
Manually tune
to
the
third station
on
your
list, press
ENTER,
and press Pre-set
#3
to
store
the station.
Continue
in
this
manner
with
any
other stations that
you
want
to store
in
the remaining pre-sets.
Then
switch
to the
other
tuning
band
(FM
or
AM)
and
repeat
the
process
for the
second set
of
five
pre-sets.
lncidentally, if
you
make a mistake or
change your
mind,
it is not
necessary to re-program
all
five pre-sets
in
sequence.
You
can re-program any
pre-set at any time:
simply tune
to
the
desired frequency,
press
ENTER, and
press
the pre-set
button
that you want to
re-program.
AIter you finish programming the
pre-sets,
you
may
wish to
post
your
list
of stations and associated
pre-set
numbers
near
the receiver for
reference.
CAUTION: When
using
the
receiver, be
careful
not to
press
the ENTER button
by
accident.
Doing so
will
activate
the ENTER mode, and
if you
then
press any
of the
pre-set
buttons
you will unintentionally
re-program
that
pre-set.
You
would then
have
to manually
re-tune to
the station
you
wanted, and re-ENTER
it into
the pre-set.
lf
you accidentally
press
ENTER,
you can
force the
tuner to
back out
of
the
ENTER mode by
tapping the
manual
TUNING
rocker
or
by
switching tuning bands
(i.e.
from
FM to
AM and
back).
14.
TUNING
DISPLAY. The display shows the
broadcast
frequency to
which the receiver
is
tuned.
(When
you select
the
AUX
or
PHONO input
the display
is
turned off.)
On the
FM band the
fifth
digit
will
be
either
0 or 5
since
tuning
occurs in
increments of
0.'l MHz.
