PREPARATION FOR USE
TURNTABLE LOCATION
Optimum performance will be secured from the
turntable and tone arm by placing the unit on a
flat, level, vibration-free surface that is resistant
to accidental jarring or impact. It is considered
standard practice to avoid installing the turntable
on or near speaker enclosures.
The power transformers used in amplifiers can
produce large magnetic fields. If a magnetic
phono cartridge is operated within such a mag-
netic field, hum may be produced. Therefore,
avoid placing the turntable near a large power
amplifier.
PHONO CARTRIDGE
Any high quality stereo phono cartridge will
provide excellent results with the Marantz 6100,
including cartridges designed for CD-4 four
channel reproduction. If you haven't already
obtained a cartridge, your Marantz dealer can
assist you in selecting one which will suit your
audio needs.

Figure 2. Mounting the Cartridge
CARTRIDGE SHELLS
The Model 6100 is supplied with one cartridge
shell. If you wish to interchange more than one
cartridge, additional shells may be obtained from
your Marantz dealer. (It is far easier to inter-
change and compare two different cartridges if
they are already mounted in shells!) The spare
shell can be kept in the receptacle located in the
surface of the base.
MOUNTING THE CARTRIDGE
When working with your phono cartridge, be
careful not to damage the stylus. Once it becomes
bent by rough handling, it cannot be straightened;
it must be replaced. If the cartridge is equipped
with a protective clip, keep the clip attached until
after the cartridge shell is installed on the tone
arm.
The cartridge shell plugs into the tone arm and is
secured by a threaded sleeve. The cartridge is held
inside the shell by two screws which pass through
the long slots in the top of the shell. Appropriate
mounting screws, nylon washers, nuts, and a small
screw driver are provided with the Model 6100.
Spacers, if needed, will be provided by the
cartridge manufacturer. Obviously, it's much
easier to install the cartridge when the shell is
detached from the tone arm.
Before the cartridge is screwed into the shell, the
small clips at the ends of the wires in the cartridge
shell should be pushed onto their corresponding
cartridge connection pins.
The wires are color coded as follows:
RIGHT CHANNEL HOT — RED
RIGHT CHANNEL GROUND - GREEN
LEFT CHANNEL HOT — WHITE
LEFT CHANNEL GROUND — BLUE
The cartridge or its accompanying technical sheet
will identify the cartridge connection pins. It may
be necessary to slightly compress the terminal
clips with your fingers to make them fit snugly on
the prongs of some cartridges.
After the wires are connected, insert the mount-
ing screws through the supplied plastic washers,
through the top of the cartridge shell, and
through the mounting tabs on the cartridge itself.
Then, attach the two nuts, just tight enough to
hold the cartridge (it is likely they will have to be
loosened again to adjust the placement of the
cartridge in the shell).
Tuck the lead wires neatly behind the cartridge.
Next, attach the cartridge shell to the tone arm:
Plug it in to the receptacle on the arm, push
inward to compress the four connector pins
inside, and twist the sleeve to tighten.
ADJUSTMENTS
Although the cartridge is mounted, the turntable
is not yet ready to play records. First, the
tracking angle must be checked; then the stylus
overhang must be adjusted; then the tone arm
balance, tracking force, and anti-skating force.
The following paragraphs will explain these ad-
justments.
STYLUS TRACKING ANGLE
When setting up the arm for playing, it is
important to check the tracking angle, because
improper tracking angle will cause distortion and
premature record wear. Most phono cartridges are
designed so that when the cartridge is mounted
on a surface parallel with the record surface, the
stylus will track at the proper angle (see Figure
3). The surface inside of the cartridge shell
(against which the cartridge is mounted) is
parallel to the record surface when the stylus is
touching the record surface. Visually check the
angle of the tone arm in actual playing position.
If it is not level and parallel with the record
surface, then it is necessary to change the height
of the tone arm by using the spacers supplied
with the phono cartridge. This, of course, requires
removing and remounting the cartridge, and some
trial and error technique. With most cartridges, no
spacers will be necessary.
NOTE: Some cartridges are built so that their
bodies are at an angle with respect to
their own mounting tabs. No attempt
should be made to change this angle.
Simply make sure that the cartridge
mounting tab surfaces are parallel to the
tone arm shell mounting surface before
proceeding with the arm height adjust-
ment.
Figure 3. Tracking Angle
STYLUS OVERHANG
The Model 6100 Turntable is designed to operate
with the least distortion when the tip of the
stylus is at a particular distance from tone arm
pivot. For this reason, the cartridge shell is
slotted, allowing the cartridge with its mounting
screws to be slid toward or away from the pivot
point. This, in effect, changes the radius of the
arc described by the stylus.
Supplied in the accessory kit is a 45 RPM spindle
adaptor. The adaptor has been specially marked
with an arrow and a cross to aid you in setting the
proper stylus overhang. Proceed as follows:
1. With the turntable unplugged, place the 45
RPM adaptor on the center spindle with the
arrow pointing to the rear of the turntable.
2. Temporarily remove the counterweight from
the tone arm.
3. Remove the arm from its arm rest and remove
the protective cover (if any) from the stylus.
4. Place the stylus tip over the cross mark on the
45 RPM adaptor. It is all right for the stylus
to gently touch the adaptor for checking
purposes, but do not exert any downward
pressure on it, or the stylus may be damaged.
5. If the stylus does not align with the cross
mark, then adjustment is necessary. Place the
arm in the arm rest, loosen the cartridge
mounting screws, adjust, and measure again.
6. Make sure that the cartridge is installed
straight; the sides of the cartridge must
remain parallel to the sides of the shell.
7. When you are sure the cartridge is in the
correct position, place the arm in the arm rest
and snug up the mounting screws.
Replace the counterweight on the tone arm.

Figure 4. Stylus Overhang Adjustment
VERTICAL TONE ARM BALANCE
The adjustable counterweight at the end of the
tone arm establishes tone arm balance and stylus
tracking force. Since no two types of cartridges
weigh the same, the balance and tracking force
must be adjusted for each cartridge being used.
First, to establish a point of reference, the entire
arm assembly (with cartridge installed) must be
balanced. If the cartridge has a removable stylus
protector, remove it, (as you would to play a
record). Release the tone arm from the arm rest.
To balance the arm, adjust the position of the
counterweight by rotating it. A numbered stylus
pressure scale plate is located immediately in
front of the counterweight. Rotating the scale
plate alone does not change the counterweight's
position. To change the balance, grasp and turn
the counterweight itself.
Adjust the weight so that the arm is level (parallel
to the turntable surface) with the cartridge
suspended in mid air. Then, without moving the
counterweight, set the stylus pressure scale plate
to indicate zero. This establishes a reference point
for setting the tracking force, which is the next
adjustment.
TRACKING FORCE
For the recommended tracking force, refer to the
instructions that accompany the cartridge.
Tracking force, the downward pressure of the
stylus against the record, is produced by simply
setting the arm off balance in the appropriate
direction. That is, the counterweight is screwed
inward (toward the arm pivot) until the desired
downward pressure is achieved.
The stylus pressure scale plate is in frictional
contact with the counterweight, so that they
rotate together when the counterweight is turned.
The numbers on the scale plate correspond to the
tracking force measured in grams. So, if the
desired tracking force is two grams, turn the
counterweight inward until the stylus pressure
scale plate registers 2.
ANTI-SKATING ADJUSTMENT
The anti-skating weight is provided to counteract
the natural tendency of the arm to “skate”
toward the center of the record as it is being
played. The more tracking force used, the more
anti-skating force required.
The anti-skating force can be adjusted by placing
the loop in the end of the monofilament line
around one of the notches in the anti-skate lever.
See Figure 5 for the values these notches re-
present. Set the anti-skating force to the same
value as the tracking force.
Place the arm in the arm rest.
Figure 5. Anti-Skate Adjustment
Plug the left and right output cables into the
PHONO jacks of your preamplifier or receiver,
(The red plug is the right stereo channel.) Be sure
the plugs are inserted completely. Loose connec-
tions will cause hum and noise.
Connect the ground wire which runs adjacent to
the two output cables to the CHASSIS GROUND
BINDING POST of your receiver.
NOTE: Depending on the cartridge there may be
occasions where it is more advantageous
to leave the ground wire disconnected.
Connect your turntable in the condition
which produces the best performance.
Then, plug the AC power cord into an outlet
supplying the proper voltage, or into one of the
SWITCHED convenience outlets on the back of
your receiver. The polarity of the AC power cord
sometimes has a bearing on the amount of hum
produced. After the system is set up and playing,
try reversing the polarity of the plug. Again,
depending on the cartridge, it may improve
system performance.
SIMPLIFIED OPERATING
PROCEDURES
1. Turn on your amplifier system and select the
Model 6100 Turntable as the source input.
2. Place a record on the turntable. For a 45 RPM
record, fit the supplied adaptor over the
turntable center spindle.
3. Place the CUE lever in the UP position.
4. Release the arm rest safety lock, and position
the arm so that the stylus is above the desired
groove of the record. The turntable will begin
. rotating.
5. Select the desired speed by depressing the 45
or 33 button (see “SPEED SELECTION”,
on this page).
6. While the record is turning, you may wish to
clean its surface with a suitable cleaning
device before playing.
7. Move the CUE lever to the DOWN position.
The stylus will slowly descend to the selected
groove. A small amount of practice will
enable precise record cueing.
8. To lift the tone arm at any time, move the
CUE lever to UP.
9. When the record reaches its end, the turntable
mechanism will automatically lift the arm,
return it to the arm rest, and shut off the
motor.
10. To stop the turntable at points before the end
of the record, you may either (a) pull the
REJECT lever, (b) use the CUE lever to lift
the arm rest, or if you're in a hurry, (c) lift
the arm manually and place it in the arm rest.
CUEING LEVER
The cueing lever, marked CUE, controls the
vertical motion of the arm lifter. The hydraulical-
ly-damped arm lifter gently raises and lowers the
arm and stylus. Obviously, using this slow motion
device is much safer for your records than
lowering the stylus by hand.
The CUE lever operates in all modes. It can be
used at any time to lift the stylus off the record.
REJECT LEVER
The REJECT lever activates the reject cycle of
the turntable. To operate the reject cycle, pull the
REJECT lever momentarily, then release it: The
arm will lift and return to the arm rest, and the
turntable will automatically shut off.
/
SPEED SELECTION
Two pushbuttons are provided on the top panel
to select the desired RPM (33 or 45). These
buttons are mechanically linked to the shifting
fork inside which shifts the drive belt from the
larger to the smaller portion of the motor pulley.
To accomplish a speed change, it is necessary that
the motor be running and the platter rotating.
Otherwise, the belt will not move from one
portion of the pulley to the other, and the
shifting fork will put a crease in the belt. This, in
turn, may cause wow and flutter.
ARM REST
The arm rest holds the arm while not in use, In
the event the turntable were jostled or bumped,
the lock on the arm rest secures the arm and
prevents damage to the stylus.
The turntable rotation stops when the arm is
manually placed in the arm rest.
TURNTABLE CENTER SPINDLE
The Model 6100 center spindle is designed to
precisely fit record center holes conforming to
the NAB standard. However, some records may
fit tightly on the spindle, because in the record
stamping process some scraps of plastic were left
sticking to the edge of the center hole. In such a
case, the scraps can easily be removed by inserting
the point of a pencil in the center hole and
turning the pencil.
DUST COVER
The dust cover attaches to the base by means of
two slotted brackets which fit into two spring-
loaded hinges on the rear of the base. The dust
cover is designed to prevent dust from settling on
your records while they play. However, it is also
important to keep the dust cover closed when no
records are being played, to prevent dust from
settling on the record mat. Even though this dust
does not land directly on a playing record, it can
be later transferred to the record surface by static
electricity. If you accidentally leave the dust
cover open for a long period of time, clean the
record mat before playing any records.

MAINTENANCE
The Model 6100 Turntable and arm are factory
lubricated and sealed. No further lubrication is
needed for these assemblies.
CLEANING THE MODEL 6100
The unit should be kept clean and dust-free. A
cloth dampened with water will remove most
dust. To clean fingerprints or oil marks from the
anodized aluminum surface or the plastic dust
cover, use a soft lint-free cloth or cotton swab
slightly dampened with a mild solution of
detergent and water. Never use scouring pads,
steel wool, scouring powders or harsh chemical
agents such as lye solution. The wooden base may
be polished with a commercial furniture polish.
The rubber drive belts should be kept free of oil
and grease. If the belt requires cleaning (as
evidenced by shiny spots or slippage), use a piece
of cloth or cotton swab moistened with
denatured alcohol to remove all traces of oil. If
necessary, clean the motor pulley and the area of
the platter which contacts the belt. Be sure to
wash your hands before cleaning the drive belt.
