B.I.C. has been a
leader in the U.S high fidelity industry since 1937 and over the years has sold
and serviced hundreds of thousands of fine turntables
Out of this
experience a new turntable concept evolved. Quite simply it is a Multiple Play
Manual Turntable, comparable in performance with the best turntables now
available, and which incorporates automatic and multiple play features without
sacrificing performance. It is a belt-drive turntable - belt drive a simple,
quiet, wow-free method of turning the platter and isolating it from the motor.
It incorporates a
program panel which allows the turntable to be operated in 3 modes;
1-As a single-play
manual
2-As a single-play
automatic in which the turntable cycles and shuts off at the touch of a button
and will play one selection as many as 6 times automatically
3-As a multiple-play
turntable that will play as many as 6 records in sequence
The B.I.C. motor is
a low-speed (300 rpm) 24-pole synchronous motor as opposed to the 1800 rpm
motors found in the majority of changers and automatics today.
Other evidences of
design sophistication include isomer shock mounts (instead of springs), an
extremely low profile , and a feather-touch cycle button which requires anly 90
gm pressure.
The B.I.C. 940 , in
addition to the features noted above, has a low-mass tone arm which
incorporates vertical tracking force adjustment in the isolated counter weight.
Anti-skating is adjusted by a knob on the program panel. The tone arm is the
equal of the most sophisticated available. It will track any cartridge, CD-4
included, at the lowest setting recommended by the manufacturer. Cueing is
viscous damped up and down.
Performance is
comparable with other manual turntables which are much more ex[pensive. The
Model 940 is designed to function with as fine a system as you choose to
assemble and yet is priced modestly enough to be a logical choice for any
system being put together on a strict budget.
The B-l-C Multiple
Play Manual Turntable represents the culmination of many years of engineering
design effort directed towards the development of a superior manual turntable
equipped with automatic, 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 range of power line voltages,
since its motor’s rotational rate is determined solely by power line frequency
(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 inherent shortcomings of conventional turntables because
its action is independent of erratic spindle-sensing mechanisms or dimensional
variations of records. The programmer allows for totally manual play or
automatic play of single records, repeat playing of single records, programmed
play 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 vibration coupling,
thereby permitting you to take full advantage of the wide dynamic musical range
now available in modern disc recordings.
Features:
The Model 940 is
wired for 117 volts, 60 cycle operation in the United States. The unit is
compatible with 50 cycle operation and can be easily converted. On the
underside of all units is a code tag which lists electrical specifications. The
Model 940 requires a 50 cycle pulley. This part is available through your
dealer or from British Industries Co. Detailed information is supplied with
each 50 cycle kit. For operation on 220 volts, contact your local dealer or
service center for a suitable step-down transformer and conversion.
Cartridge Mounting
Screws The Model 940 is supplied with several pairs of machine screws,
No. 3-48 American
standard machine screws.
Belt The drive belt
used is made to exact specifications for maximum performance. If ever a new
belt is required, we highly recommend that you purchase the genuine, exact
factory replacement as inferior replacement belts will seriously downgrade the
performance of your unit. This is also available through your local dealer or
British Industries Co.
Motor B-l-C
Turntables incorporate a 24-pole, 300 rpm motor of outstanding characteristics.
The design nature of
this motor insures many trouble-free hours of listening pleasure and very
seldom, if ever, requires maintenance or lubrication.
Speed The Model 940
will play records recorded at 33-1/3 and 45 rpm.
Record Size Twelve
inch 33-1/3 rpm records may be stacked and played automatically on the
automatic spindle supplied with the unit. Seven inch 45 rpm records may be
stacked and played automatically on the optional automatic 45 rpm adaptor,
Stock No. A-2.
All other size
33-1/3 and 45 rpm records can, of course, be played manually.
Maximum Number of
Records B-l-C Turntables accept and play up to six records automatically.
Cartridge B-l-C
Turntables will accept any cartridge manufactured at the time of this writing,
and will track at the lightest force recommended by cartridge manufacturer.
Cable Capacitance
The total cable capacitance (all wiring) of the Model 940 is less than 125 pf
and, therefore, is perfectly compatible with Discrete Four Channel records
(CD-4).
