The B.l.C Multiple Piay Manual Turntable
represents the culmination of many years
of engineering design effort directed
towards the development of a superior
rnanual turntable equipped with auto-
matic, multiple record playing facilities.
Its drive system utilizes a slow speed
(300 rpm) 24 pole synchronous motor,
and belt drive, previously found only in
fine manual turntables.This results in
significantly reduced rumble, wow, and
flutter since idler-pulleys are totally
eliminated The Model 940 maintains
precise speed over a wide ran ge of power
line voltages, since its motor's rotational
rate is determined solely by power line
f requency (50 Hz or 60 Hz).
The tonearm system features minimal
friction bearings, low mass and
resonance, stylus force, and tonearm
balancing and an isolated counterweight
to maintain optimal tracking force from
the first to last record played. Another
exclusive feature, a pivotable cartridge
shell, permits easy cartridge installation.
The programmer system eliminates the
i n herent shortcomings of conventional
turntables because its action is inde-
pendent of erratic spindle-sensing
mechanisms or di mensional variations
of records. The programmer allows for
totally manual play or automatic play of
single records, repeat playing of single
records, programmed pl?y of up to six
records, or automatic play of multiple
records with programmed repeatability of
the last record, all by means of a single
touch button.
The suspension system has been
designed to prevent mechanical or
acoustic vi bration coupli ng, thereby
permitting you to take f ull advantage of
the wide dynamic musical range now
available in modern disc recordings.

unit plate at the points indicated on the top cardboard packing
piece. DO NOT lift the unit by grasping the tonearm. Whenever
possible, the packing material should be retained in the event re-
shipment is necessary. ln any event, do not discard the packing
material until all of the accessories described below are accounted
fo r.
The top styrofoam filler contains the following:
1 A short manual spindle for playing single records
2, A long automatic spindle for playing up to six records automatic-
ally.
3. Tonearm counterbalance weight,
4. A manual 45 rpm adaptor for playing large hole records, one at a
time.
5. Cartridge mounting hardware; this contains the various screws
that are needed for mounting the cartridge in the pickup head.
6, Transit wing nuts (2)
7 . Extra tonearm shell lock screw.
B. Screwdriver
Also, make certain that all rubber bands securing the line cord,
audio cables, the tonearm tie, etc,, are removed along with all other
packing pieces.
Packing pieces are installed between the unit plate and turntable.
They must also be removed and, if possible, should be retained as
they are avery important part of the packing if the unit is ever
shipped
The audio cable is packed in a wedge on the right side of the unit.
lnstalling the Unit on the Base
Both the 820 Base and WB20 Base are supplied with a bottom
safety cover which eliminates any possibility of mechanical hazard.
Comprehensive instructions are included with each base.
PROPER INSTALLATION IS EXTREMELY IMPORTANT DO NOT
INSTALL THIS UNIT ON ANY DEVICE OTHER THAN THE OFFICIAL
B2O OR WB2O BASES

Cartridge Installation and Adiustment
ln order to take advantage of the many
features of the B.l.C tonearm, it is ex-
tremely important that the cartridge be
properly installed and th e various
adjustments pertaining to the cartridge
be made. These are described below.
Rotation of the Cartridge Head
All turntables use some form of cartridge
slide or clip to pre-mount the cartridge
and fasten it to the arm. Electrical contact
for transmission of the minute cartridge
signals depends on four surface-to-
surface contacts, any one of which may
cause intermittent signals or open
circurts. The B.l.C 940 employs a rotating
pickup head which is rigidly iocked in
place by a set screw lccated on the top
of the tonearm, (Fig A) Rer.nove the set
screw and rotate the pickup head counter
clockwise BE SURE NOT TO LOSE CR
MISPLACE THE SET SCREW IN THE
EVENT THIS OCCURS, AN EXTRA
SCREW HAS BEEN SUPPLIED THE
CARTRIDGE HEAD IS NOT REMOVABLE
AND DAMAGE CAN OCCUR IF IT IS
PULLED FORWARD
Mounting Cartridge in Head
The B.l.C 940 is supplied with several
sets of varied length cartridge rnounting
screws. lt is important that the rnounting
screws used are the correct len gth
ln most cases the mounting screws
supplied by the cartridge manufacturer
should be used. However, if you do not
have these screws, proceed as follows:
From the sets of screws supplied with
the B.l.C 940, select the screws that
appear to be the proper length to pass
through the cartridge mounting bracket
Place one screw through the bracket, To
make certain it is not too long, place the
bottonn of the cartridge as shown in the
diagrarn below and note whether the
screw projects below the simulated
pickup head rnounting bracket lf too
long, use the next shorter screw, When
the correct length has been selected, use
a srnall screwdriver to secure both
screws to the pickup head (Fig B)

WE STRESS THAT IF THE INSTRUC_
TIONS ARE NOT CAREFULLY
FOLLOWED AND THE CARTRIDGE
CONNECTORS ARE BROKEN, THE
REPAIR OF THE UNIT WILL NOT BE
COVERED UNDER WARRANTY
Gartridge G rounding Strap
The tonearm ground of the 940 is carried
up to the metal plate in the tonearm head.
With some cartridges a ground loop can
occur-if this difficulty is encountered,
remove the grounding strap f rom the
cartridge. Consult the cartridgd
manufacturers instructions regarding
removal of the ground strap.
Re-positioning Pickup Head
After the cartridge has been correctly
installed in the head, rotate the shell
clockwise so that the hole which receives
the screw becomes visible. Replace
the set screw and tighten f irmly.
Counterweight I nstallation
The counterweight should be installed
on the tonearm in the following manner.
Place the counterweight at the end of the
tonearm, with the numbers facing forward,
and rotate it in a counter-clockwise
direction (Fig D). The counterweight
must be installed and taken off the
tonearm by a winding action ONLY, not
by directly pushing or pulling. Rotate the
platter in a clockwise direction approx-
imately 5 turns to make certain that the
mechanism is f ree and the unit is not in
cycle. Also, make certain that the cueing
lever is in the play position. With the
tonearm released from its locked position

and anti-skate knob set to "0" (zero),
continue to rotate the counterweight
until the tonearm is perf ectly balanced,
f loating parallel to the turntable. When
this is accomplished, the tonearm will be
approximately level to the extension of
the tonearm pickup rest.
Setting VTF : Vertical Tracking Force
(Stylus Pressure)
The top of the tonearm tube contains a
reference line. Rotate the black VTF Cisc,
(not the entire counterweight) , uttil "0"
lines up with its reference line, Rotate the
entire counterbalance weight by grasp-
ing the knurl at the rear in a counter-
clockwise direction. The VTF disc will
move with the counterbalance weight,
Turn the counterweight until the VTF
recomrnended by the cartridge r"nanu-
facturer corresponds with the reference
line ln order to set the VTF higher than
2 grams, the counterbalance weight will
have to be rotated more than one f ull
turn and the numbers in red indicate
the pressure (Fig. A) .
Setting Anti-Skate Force
Set the anti-skating force knob to the
number of grams recommended by tf^re
manufacturer of your cartridge (Fig. B).
The forces shown on the controt panel are
calibrated for elliptical styli, For conrcal
styli, set the knob approxinrately 2CCo
less than for an elliptical type, Example:
lf VTF is 21/z grams set anti-skate fcr-
2 grarns.
Connecting Your B.l.C Model 940
Turntable to an Audio Amplif ier
Audio Cable
The Model 940 is supplied with a double
ended color coded audio cable This
cable was selected to provide minimui-n
capacitive loading effects on high fre-
quency response of your cartridge. This
is especialiy important if your cartridge is
capable of playing CD-4 discrete four
channel recordings. lf longer cables are
required, rnake certain they are of a lclv
capacity type or check with the man u-
facturer of your cartridge for his reccrn-
mendations regarding cable type and
length limitations.

The ground wire supplied with the
tu rntable should be connected to a suit-
able "ground" point on the metal
chassis of you r amplif ier. Most am-
plifiers provide a convenient terminal

on the rear panel for this purpose. Fail-
ure to ground this wire will result in an
inordinately high hum level when
attem pting to play records
Power Cord Connection
Your model 940 is designed to operate
f rom a supply voltage of 1 05 to 130 VAC
60 Hz (50 Hz adapter available). Con-
nection of the power cord to a higher
source of voltage or to a DC power
source willcause immediate damage to
the unit and is not covered by the
warranty. lf you use this product in
areas powered by 220 or 240 volts, con-
sult your dealer for proper instructions
regarding adaptation of the unit for
such use.
With the programming lever set to the
OFF position, plug the power cord
into a suitable outlet Many amplifiers
provide convenient receptacles on their
rear panels, to which the tu rntable
power cord may be connected (Fig. A)
Often, these receptacles are labelled
"SWITCHED" and "UNSWITCHED".
Choose an "UNSWITCHED" receptacle
for powering the turntable. By so
doing, rf you shut off the amplifier, the

Operating Procedures
Before attempting to play records, make
certain that the tonearm retaining lock
(Fig B) on the tonearnr rest is loosened
by moving it to the right with forefinger.
Most cartridges are f itted with a stylus
guard or protective cover. Make certain
this cover is removeC or pivoted so as to
expose the stylus tip
Set the speed selector lever (Fig C)
for the type of record you wish to play
The Model 940 plays 1 ztt 33 rpm records
when the s peed selector lever is set for
33', 7't 45 rpm reco rds when set to 45.
When playing a 45 rpm record, install the
man ual 45 rpm adaptor over the manual
spindle, which should be placed in the
center hole of the turntable. An optional
multiple play 45 rpnr adaptor is available.
Place this adaptor over the autornatic
spindle to play up to six records. (See
page 1 0)
Manual Play of a Single Record
lnsert the manual spindle (Fig D) and
move the prog ram rner control knob
(Fig. E) to the man ual position. The
turntable should begin to rotate at the
selected speed. Carefully lift the tone-
arm by means of the tonearm f inger

lift, and place it on the record After
the record has been played, the tone-
arm will return to the tonearm rest and
the unit will shut off You may also
use the cueing lever while playing
single records manually. For use of
this feature, refer to page 1 1 . lf you
wish to discontinue playing in the mid-
dle of a record, depress the cycle button.
The tonearm will return to its rest,
and the unit will shut off . Alternatively,
you rnay lift the tonearm from the record
and manually return it to the rest The
turntable should then be turned off by
moving the programming lever to the
OFF position.

Turning Off the Unit
The u nit can be tu rned of f at any time
in one of two ways:
The cycle button can be depressed to
advance the programming cycle to
the next lower program number until
the " MAN " position is reached,
Depressing the cycle button once again
willcause the tonearm to return to the
tonearrn rest and complete shut off of
the turntable.
Alternatively, the tonearm can be
lifted manually by means of the tonearm
finger lift and returned to the tonearm
rest. The programming lever should
then be moved to the OFF position to
turn off the unit (Fig C)

T"re ts'l'C mechanism is exceptionally
sirnple.','litlr a rninimurn number of
moving paris.
Reccrds are handled with two-point
support as opposed to the umbrella
type si n gl e-support system commonly
used. The B'l'C system stabilizes the
records and insures reliable dropping.
There are other automatic turntables
that use a two-point record support
system, but the 940 differs in that
automatic shut-off is cornpletely inde-
pendent of the center automatic spindle.
This eliminates the critical sensing
nature of the spindle and is one of the
reasons for the reliable changing
capabilities of the B'l'C unit.
This design also makes it much
simpler to accommodate records with
variations in the center hole diameter
or thickness,
lnstalling Multiple Play Spindle
To play u p to six records in seq uence,
remove the short manual spindle from
the turntable.
Place the multiple play spindle
in the center of the turntable. Rotate

it until it lines itself up with the keyway
in the center of the tu rntable, press the
spindle firmly down until a distinct
"click" is heard (Fig.A)
Count the number of records you are
putting on the multiple play spindle and
place the record hold-down clip (Fig. B)
on the platform in the up position
prior to installing records. When the
records are sitting on the shelf of the
spindle and the edge of the record
platform, lower the hold-down clip to
stabilize the records in place.
Move the program selector control
knob to the number corresponding to
the records you have placed on the
spindle. Depress the cycle button and the
tonearm will play all of the records
automatically. When the last record has
played, the unit will shut off. Fo'r
example, to play f ou r records, the four
records are placed on the automatic
spindle and the programmer is
advanced Io 4 The cycle button is
depressed, the four records play and the
programmer determines when it is to
shut off .
Multiple Play Plus Repeat
of the Last Record
lf you wish to play less than six records
and would like the last record to be
repeated one or more times, simply
move the program selector knob to the
number of records plus the number of
adCitional plays desired. For example,
if three records are on the spindle and
you wish the last record to play once
and repeat three times, simply set the
program control to the number 6 (Fig. C).
Removing Multiple Play Spindle
All records must first be removed. To
remove the records, tilt the stack down
and away from the record platform and
lift up. The automatic spindle can then
be removed by grasping and lifting
straight up.
Cueing and Pause Control
The cueing lever (Fig. D ) is used to
raise or lower the tonearm during
automatic or manual play. Moving the
control forward raises the tonearm,
pushing it back lowers the tonearm.
Stylus Set-Down Adjustment
and Tonearm Height
Your Model 940 was carefully
assembled and all necessary ad just-
ments were performed at the factory.
There are, however, two minor adjust-
ments that may have to be made to suit
your particular cartridge. One adjust-
ment controls the point at which the sty-
lus lands upon the record's surface. All
records contain a groove guard (Fig E ).
ldeally, the stylus should land inside the
groove guard just bef ore the recorded
portion of the record (Fig E) The tone-

Lubrication
All pivot points and bearing surfaces
have been lubricated at the factory and
will seldom, if ever, require f urther
attention Should lubrication be
required, we recommend this be
performed by B"l.C or one of its
authorized service stations. lf you prefer
doing this yourself, we recommend
you purchase a Tech nical Service
Manual which provides full details and
explicit instructions on this entire
su bj ect
Record Care
Keep the cartridge and stylus clean
and replace if worn. Periodically have
the stylus inspected by your dealer
Retu rn all records to their protective
sleeves and jackets Do not leave records
on the tu rntable f or long periods, if not
in use.
Store vertically rather than horizontally
or flat. lf possible, store records at
average room temperatures, Do not
perr-nit them near or in contact with heat
producing devices, such as radiators,
electronic equipment, amplifiers, etc.
Excessive temperatures tend to cause
warpage of records. Avoid hand ling the
groove surfaces as this will deposit a
film of oil on the grooves. Hold records
by their outer edges when mounting or
removing from turntable to keep
records clean
