What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Dual 728Q turntable


Quartz PLL direct drive, fully automatic operation, and Dual's s exclusive Ultra Low Mass tonearm system

Dual exclusive features

ULM tonearm and cartridge system: less than 8 grams total effective mass

New XM300 alloy increases rigidity, reduces resonance

Hydrodynamic suspension system for tonearm, motor and platter

Turntable acoustic isolators minimize acoustic feedback and external shock

Tunable anti-resonance filter with viscous damping

HDC (High Damping Compound) housing provides high internal damping and suppresses external interference

Unique dust-cover hinges allow placement close to rear wall

 

The moment the ULM tonearms touches down on your record, you will appreciate what Dual engineers have accomplished. You will hear a purity of tone that has never before emerged from the grooves. Even if the record is warped.

 


The Ultra Low Mass. tonearm

The Dual straight-line tubular tonearm is suspended in a four-point gyroscopic gimbal which centers and balances the tonearm mass where it pivots. The vernier-adjustable counterbalance establishes zero balance with micrometer-like precision. A tempered flat-wound spring applies tracking force at the pivot - without increasing effective mass. The tonearm remains in perfect dynamic balance throughout play, even if the turntable is not level.

The ULM tonearm can accommodate cartridges weighing as little as two grams. ULM cartridges made to Dual specifications weight only 3,5 grams, including mounting bracket and hardware.

 


ULM is Dual's exclusive Ultra Low Mass tonearm and cartridge system with total effe3ctive mass less than 8 grams. That's less than half the mass of conventional tonearm and cartridge combinations.

This major breakthrough by Dual has been acclaimed throughout the audio industry, especially by the independent test labs.

These labs have begun to use warped records as 'real-life' test instruments

One lab, after making the usual measurements, also listened to a record played by the sme ULM tonearm and cartridge system. There is no way measurements, or mere words, can describe the acoustic presence, highs re crystalline, with a purity we haven't heard before. The bass is so clean that one can hear new sounds from records, such as the harmonic vibration of unplayed strings on the double bass, overall definition and transient response were outstanding.

 

Hydrodynamic suspension system

Radically new design floats the tonearm , motor and platter as one unit on four cylinders, each filled with special viscous fluid. This system absorbs virtually all spurious energy originating in sound waves as well as vibrations caused by footfalls or other movements in the room.

Two suspension systems

There are two separate and independent suspension systems, each highly effective in isolating the tonearm from acoustic feedback and other music-muddying interferences. The Hydrodynamics system floats the tonearm, motor and platter as one unit on four accordion-like shock absorbers, each filled with a special viscous fluid.

The second suspension system incorporates four tunable acoustic isolators where other turntables simply have feet. Each of these isolators is adjustable to provide maximum protection from either acoustic feedback or external shock. No more tip-toeing across the room to keep the tonearm from jumping. And no more cutting the bass to eliminate feedback.

 


Tunable anti-resonance filter

Like all other systems with mass and compliance, tonearms and cartridges tend to vibrate and cause undesirable resonances. These resonances cannot be entirely eliminated, but unless minimized they cause power-draining subsonic woofer-cone movements. You hear the results as muddy bass. Dual engineers have solved this problem with the unique tunable anti-resonance filter.

Housed in the counter-balance, the anti-resonance filter can be precisely tuned to match the tonearm to the mass and compliance of all available cartridges. The tonearm is made of the special new XM300 aluminum/magnesium alloy which increases rigidity and reduces resonance.

 

Ultra Low Mass

Hydrodynamic suspension, tunable acoustic isolators, tunable anti-resonance filter - all important contributions leading to perfection in record playback. And all Dual exclusives. Equally important, the materials, the quality control exemplify all that has made Dual precision and reliability so highly regarded throughout the world.

Luxman PD-272 turntable

Direct-Drive Turntable

A new direct-drive turntable from Luxman at a modest price. A brushless and slotless DC servo motor and a straight, low-mass tonearm offer superb Wow and Flutter no more than 0,03% and excellent Signal-to-Noise Ratio at 60 dB

Brushless and Slotless DC Servo Motor

Excellent woa and flutter characteristic together with stable rotation are assured by adopting a Brushless and Slotless DC Servo Motor in which slots are completely removed to eliminate unevenness of rotation caused by electro-magnetics, and further a turntable platter of high inertia makes it possible to distribute the large mass of platter weight around the outer contour.

Straight0Type Tonearm

A straight type tonearm is adopted to eliminate resonance caused by lack of intensity which tends to be found on the tonearm exclusively designed for high compliance type cartridge, and at the same time the root of the tonearm is of double-pipe structure to strengthen anti-resonance affect.

Further, the cartridge shell is integrated to the tonearm, thus resonance is suppressed down to the minimum. Also such problem as poor contact of cartridge terminals is removed.

 

Acrylic Dust Cover

For the dust cover, an acrylic resin is adopted which provides a very smooth surface and excellent characteristic against acoustic, feedback. The entire cover is detachable with semi-free-stop hinges.

Ultra Thin Type OI Core Transformer

An ultra thin type OI core transformer of the least-leakage flux, it adopted which is smoothly housed in the smart chassis. This contributes to the realization of stable rotation and excellent signal-to-noise ratio.

Platter Mat

The platter mat is so designed as to realize firm retention of the disc. To minimize unnecessary space between disc and platter mat, the plane is procured between the two by making the contour of platter mat suitable to that of disc.

Of course the platter mat not only damps discs but the platter itself thanks to high density rubber material, and further it is exactly inlaid to the turntable platter. The surface with special treatment ensures superb contact to discs.

 

Functions

A unique switch controls both power turn-on and turn-off and speed selection through the use of a single switch. A stroboscope of mirror reflex type, oil damped cueing system, anti-skating device etc, are all ideally arranged based upon human engineering considerations.

BIC 940 turntable

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).

Luxman PX-99 turntable

Semi-Automatic Direct Drive Turntable

With the PX-99, Luxman has combined the most important features and performance with a striking and simple design.

The motor is direct drive, and has no noisy mechanical linkages and resonance-prone parts. It's also a quartz-locked motor, assuring you of accurate speed and stability.

The tonearm represents a new generation of low-mass, low-friction Luxman designs. It is statically balanced so you can adjust tracking force with exceptional accuracy. The headshell is low in mass, rigid, and removeable. And because the PX-99 is semi-automatic, the tone arm lifts off the record at the end of play, and allows the PX-99 to shut itself off.

A unique feature of the PX-99, when used with Luxman KX-Series cassette deck, the Auto Pause Output puts the cassette deck in the pause mode when the record has reached the end of play.

The PX-99 pays attention to everything that's critical in turntable design. Rumble is inaudible. Wow and Flutter can hardly even be measured. Tracking ability is flawless.

 


Features:

Optical Sensing Arm Lift System - when record playback is finished, the tonearm automatically lifts and shuts off the motor because the optical circuit senses the lift-off point, it makes no mechanical contact with the tonearm at all while playing records, so operation is smooth and accurate

Auto Lift Control Switch - the Auto Lift Control is useful for playback of records with a music groove engraved very close to the label. The tonearm is designed so it will not lift off, even at the innermost part of the disc.

New Static Balanced Straight-Light Tonearm - the PX-99's long straight arm has better trackability than the regular short S-shaped arm used on most turntables. It also has very low mass and low resonance. The Low Mass Arm realizes accurate sound reproduction even from high dynamic range, digitally recorded records.

Auto Disc Pause - when activated  a built-in circuit of the PX-99 automatically places your accompanying KX-100, KX-101 or KX-102 cassette deck in the pause mode from the record mode, when the record being taped reaches the end of play. Allows you to leave the system unattended while taping.

Cybernet CP-300Q turntable

Quartz Control Direct Drive Semi-Automatic Turntable

You can hear the difference in a Cybernet component. That's because Cybernet is a world leader and innovator in the field of electronics and designs all of its audio products to very exacting specifications. And that's why, whichever Cybernet component you purchase, you can be assured of excellent performance, incredibly accurate sound, high reliability and long life.

 

Quartz Control, Direct-Drive System

The CP-300Q combines one of the finest systems of rotational accuracy - quartz control direct-drive - with the exceptional convenience of front panel operation

The system starts with a full-cycle FG (Frequency Generator) servo motor. It incorporates full IC design for outstanding performance and reliability. With quartz control, you're assured of incredible rotational accuracy it any possible trace of speed drift is detected, corrective torque is immediately applied. The specifications verify the turntable's exceptional performance. Wow and Flutter is very low 0,05% WRMS, Signal-to-Noise Ratio is an inaudible -68 dB DIN-B. the result is sound quality true to the original source. And with front panel control, everything is right where you want it.

 

Semi-Automatic Turntable Control

To start operation of the CP-300Q, place the tonearm on the record surface. From there on, everything is totally automatic. When the end of a record is reached, the tonearm lifts up, returns to the rest position, and the turntable motor is shut-off. You won't have to worry about the stylus getting caught in the lead-out grooves of the record, which can happen with manual-type turntables. The result is less wear on your stylus, records and turntable.

 

Front Panel Controls for Optimum Convenience

The important operating controls of the CP-300Q are right on the turntable's front panel, making operation extremely easy and convenient. A speed selector provides a choice of two speeds; 33-⅓ and 45 rpm. A variable pitch control and illuminated stroboscope allow speed variations by up to ±4 %. Raising the pitch control knob allows the Quartz system to be removed. A "reject" button provides automatic return of the tonearm anytime during record play. And all these controls can be operated even when the dust cover is closed giving added protection to your records.

 


Low Mass, Tubular Aluminum Tonearm

The tonearm is of straight, tubular aluminum construction for excellent damping of outside vibrations. Its low-mass design, and finely machined, low-friction bearings, provide excellent tracking ability and exceptional sound quality.

 

High Feedback Resistance

The CP-300Q features base construction incorporating individual rubber feet to isolate any source of mechanical or acoustical feedback. By effectively resisting outside vibrations, the result is clean, accurate sound reproduction.

 

Smooth Tonearm Set-Down with Viscous-Damped Cueing

The cueing system is viscous oil-damped, allowing smooth, gradual descent of the tonearm. Operated with the manual cueing lever located next to the tonearm, oil-damping provides greater precision, reduced needle bounce and less chance of record damage.

 

Pitch Control with Illuminated Stroboscope

The CP-300Q provides (by pulling up the pitch control knob) a variable pitch control for both 33-⅓ and 45 rpm speeds. In combination with the easy -to-read illuminated stroboscope you can vary the speed up to ±4%. This lets you speed up or slow down a record, allowing alignments of pitch for any accompanying instrument.
