Initial Setup (continued)
Assembling the Dust Cover
1.
Insert the T-shaped ends of the dust cover hinges into the
two
hinge receptacles located at the back of the turntable housing.
When properly installed, the flat part of the cover hinges should
be
facing away from the turntable housing at about a 45
0
angle.
2.
Holding the dust cover over the turntable, carefully guide the cover
hinges into the
two
slots molded into the rear of the dust cover.
The springs
in
the hinges allow the cover to
be
held open
at
about
a 45
0
angle if desired. (Note: There
is
only one "open" position;
the hinges do NOT permit the cover to stand "straight up.")
3.
To
remove the dust cover from the turntable, gently disengage the
hinges from the slots
in
the cover. This
is
usually easier when the
cover
is
in
the "closed" position. Slowly
and
carefully lift straight
up until the cover
is
clear of the unit. The hinges may then
be
removed from the turntable base, if desired.
Setting Tone Arm Balance and Tracking Force
To
allow the cartridge to properly track
in
a record, the tone arm
balance
and
tracking force must
be
carefully set to the cartridge
manufacturer's specifications. Failure to properly set up the tone arm
assembly
can
cause damage to the cartridge stylus and/or records.
(Note: Once the stylus protective cover
has
been removed
and
the tone
arm locking clamp
has
been released, take
extreme
care
not
to
damage
the stylus.
Do
not allow it to
drag
or
scrape across the slip mat.)
Tone Arm Setup:
1.
Set the anti-skate adjustment to
"0".
[Figure
2,
page
4,
#26.]
2.
Remove the clear protective stylus cover, carefully sliding it
straight
forward,
off the front of the cartridge.
3.
While gently holding the headshell to stabilize the tone arm,
release the tone arm locking clamp. At this point, the tone arm
is
unbalanced
and
free to swing.
4.
While gently holding the headshell, carefully rotate the
counterweight until the tone arm
is
horizontally balanced
and
hovers freely just above the platter without touching the platter
surface.
5.
Lock the tone arm back into the tone arm rest.
6.
While holding the counterweight steady,
and
without any rotation,
carefully rotate only the black stylus force gauge
ring
(which turns
independently of the counterweight) until the
"a"
on
the gauge
ring
lines
up
with the centerline marked along the top of the rear
arm.
7.
Refer to the cartridge manufacturer's specifications for
recommended tracking force. Rotate the entire counter-weight
counterclockwise without touching the black gauge ring, moving
the counterweight forward, until the desired value
on
gauge ring
lines up with the centerline marked
on
the rear arm. Refer to the
specifications section for tracking force value for the cartridge that
shipped with the turntable.
Setting Anti-skate
A small inward "anti-skating" force
can
be
applied to the tone arm
to compensate for outward forces resulting from cartridge/ tone
arm interaction with the record. For best performance during normal
turntable use, set the anti-skate control knob [Figure
2,
page
4,
#26] to
the same setting
as
the tracking force dial. Refer to the specifications
section for tracking force value of the cartridge that shipped with the
turntable.
In
case of substantial use of back-cueing, scratching or reverse-direction
operation, you may prefer to use less, or
no,
anti-skate compensation.
Setting Tone Arm Assembly Height
The
tone arm assembly height adjustment allows for the tone arm
to
be
positioned parallel to the record surface, when using extra-tall
cartridge bodies, thick slip mats or thick records
(i.e.
old 78's).
To
raise
or
lower the tone arm assembly: First, loosen the height lock [Figure
2,
page
4,
#281;
then rotate the height adjust dial [Figure
2,
page
4,
#211
located at the base of the tone arm assembly. The scale
is
calibrated
in
millimeters (mm). When finished, tighten the height lock to secure the
adjustment.
Connections
Audio
Connect the audio output cable to the appropriate input jacks
on
your
mixer, amplifier, soundcard or other device based
on
the setting of the
pre-amp selector switch. Firmly connect the
Red
RCA-type plug to the
right channel input
and
the White RCA-type plug to the left channel
input. (Note: Adapter plugs might
be
required to connect the turntable
to computer sound cards
and
other devices.)
Connecting to Computers with
USB
Input
The
USB
cable (included) connects your AT-LP120-USB turntable to
your computer without need for special drivers. Refer to included
software guide
(also
available online at www.audio-technica.com)
before connecting the turntable to your computer.
Connecting to Computers
or
Audio Devices with 3.5
mm
Input
The
AT-LP120-USB connects without adapters to devices equipped with
RCA
connectors.
For
maximum flexibility,
we
have included
two
adapter
cables to fit other popular audio inputs.
The first of these adapter cables - dual
RCA
to stereo 3.5
mm
mini-plug
(male) -
is
designed to
fit
most popular computer* audio inputs. It may
also
be
used to connect the turntable's
RCA
output to other equipment,
including:
• a stereo/boombox* equipped with a 3.5 mm minijack
• input powered speakers* equipped with a 3.5
mm
minijack
• input a mixer* or
PA
system* equipped with a 3.5
mm
minijack
The second included adapter cable - dual
RCA
to stereo 3.5
mm
mini-
plug (female) - permits connection of the turntable output to amplified
speakers* or similar devices. The 3.5
mm
stereo minijack
on
the cable
adapter accepts stereo mini-plugs.
To
use either adapter cable, connect the turntable's red
and
white
RCA-
type plugs to the cable adapter's RCA-type jacks.
* When using either cable adapter, always set the AT-LP120-USB
turntable's Pre-amp Selector Switch to the "LINE" position.
(Switch
is
located
on
the back of the turntable.)
NOTE:
If connection
is
desired to a mono amplifier/speaker, make
certain to use a stereo-to-mono adapter, available from your dealer or
an
electronic parts store. Inserting a mono plug
in
the stereo jack will
disable one of the stereo channels. Other adapter cable configurations
will
be
available from dealers
and
parts stores for connecting to devices
needing different terminations.
Finally, after
all
other connections
are
made, attach the included
AC
power cord to the turntable; note that the small connector only goes
in
one way. Then connect the power cord's plug to a convenient
AC
outlet.
