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.

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.

Cybernet CP-200D turntable

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.

 

Direct Drive for Outstanding Performance

The Cybernet CP-200D incorporates a direct drive system to reduce potential sources of wow, flutter and rumble. By eliminating the use of high speed motors, bells or idlers, the direct drive system achieves outstanding performance. Wow and Flutter is reduced to a mere 0,05% WRMS, contributing to exceptional rotational accuracy. The Signal-to-Noise Ratio of -68 dB (DIN-B) translates into extremely quiet turntable operation. Combined, these advanced technologies contribute to the line sound quality of the CP-200D

 

Semi-Automatic Turntable Control

With semi-automatic control, when the end of a record is reached, the tonearm automatically lifts and returns to the rest position and the turntable is shut-off. A "reject" button will allow return of the arm at any point in the record. One of the major benefits of semi-automatic control is that your stylus won't stay continuously in the lead-out grooves of the record, as in manual turntables. This means less wear and longer life for the record turntable and cartridge stylus

 

Convenient Front Panel Controls

The most important operating controls are located right on the front panel for maximum convenience. A speed selector provides a choice of either 33-⅓ or 45 rpm. If you desire to change the speed slightly, a variable pitch control and illuminated stroboscope are provided for both speeds. A "reject" button allows return of the tonearm to the rest position. And all controls can be operated even when the dust cover is closed, thus providing extra protection for 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.

 

Base Material Resists Acoustic Feedback

The base of the CP-200D has been specially designed to provide high resistance against both mechanical and acoustical feedback. The dense cabinet material together with shock-absorbent feet provide resistance against vibrations that might otherwise tend to degrade the sound quality.

 

Viscous-Damped Cueing Control

The tonearm is viscous oil-damped for smooth lift or set-down when using the manual cueing lever. With viscous-damped cueing, the tonearm can be lowered onto the record with greater precision and less chance of cueing error.

 

Pitch Control with Illuminated Stroboscope

The CP-200D provides a pitch control with a plus or minus range of 4% for both 33-1-3 and 45 rpm. This effectively allows you to speed up or slow down the record. And an easy-to-see, illuminated stroboscope gives a visual readout for fine-adjustment of the turntable's speed.

 

FG Servo Control

One of the reasons for the outstanding rotational accuracy of the CP-200D is the FG (Frequency Generator) servo-controlled DC motor. Any possible trace of speed drift is automatically detected and immediately corrected. Full IC (Integrated Circuitry) design adds to the system's overall performance reliability.

Features

E-D Servo tonearm for reduced resonance

Double-Servo Quartz control

Cog-free coreless DC servo motor

Electronic resonance-damping, tracking-force and anti-skate controls

Computerized fully automatic convenience with repeat

 

The design objectives for our top-of-the-line turntable were simple; eliminate all unwanted resonance, speed error, noise and vibration while offering fingertip computer control convenience. The superlative QL-Y5F attests to our success, and we were able to make it beautiful to boot Read on.

 

JVC E-D Servo tonearm

A genuine breakthrough

JVC engineers isolated "tonearm resonance" as the most inimical of all conceivable resonance in a turntable, since it colors reproduction, adds distortion (particularly intermodulation) and prevents accurate arm tracking. JVC's E-D Servo tonearm solves the problem of "sympathetic resonance". See the full description of this remarkable tonearm on the next page.

The E-D Servo tonearm - construction

Two coreless linear motors are used in the E-D Servo tonearm. One, housed inside the structure positioned to the right of the vertical bearing, controls and adjust the arm's vertical position in relation with the record's surface. The other, positioned below the tonearm base, controls and adjust the arm's horizontal position in relation to the record groove.

Even warped records are no challenge to the E-D Servo tonearm

The E-D Servo system successfully damped the tonearm to shut out audible damage caused by low-frequency infrasonic and external vibration. The result is better record tracking, lower distortion a higher signal-to-noise ratio and even better Wow and Flutter.

 

Our Improved Double-Servo Quartz system has made speed control 30 times more accurate

Speed accuracy is nearly flawless thanks to the Double-Servo Quartz speed detection system for the platter motor

 

Coreless DC servo motor is cog-free yet powerful

Our coreless DC servo motor has no cores for cog-free, smooth rotation, yet has 50% more torque than conventional coreless designs, thanks to a push-pull drive circuit.

 

Up-front, light-touch controls and fully automatic operation for a unique operating experience

All the controls for this JVC masterpiece are on the front panel. All arm movements - up, down, left and right - are possible in the manual mode via light-touch buttons. Full automatic operation is supervised by a microcomputer and initiated by the Start/Stop button.

JVC QL-Y3F turntable

 

Features:

Electronic Tonearm technology Teamed with Quartz Precision

E-D Servo for horizontal arm movement

Double-Servo Quartz control

Cog-free coreless DC servo motor

Electronic anti-skate control

Computerized fully automatic convenience

 

It holds its own against the most expensive turntables on the market, even comparing favourably with the sophisticated QL-Y5F from which it borrows many of its features. Yet the QL-Y3F is priced well below the level set for professional equipment of similar specs and features. Speed error is practically nil thanks to the JVC Double-Servo Quartz detection system and our coreless DC servo motor; handling convenience is enhanced by fully automatic controls identical with those of the QL-Y5F, and the problems of spurious arm movements are solved with our E-D Servo tonearm

 

E-D Servo for horizontal arm movement falls resonance

A modified version of the JVC E-D Servo tonearm is at work in this model to keep horizontal arm movements under control. As in the more elaborate QL-Y5F, the arm base contains a coreless linear motor with a horizontal velocity detection system, intermodulation distortion is never a problem, since infrasonic signals (10 Hz or lower) are remedied harmless by this arm control servo. The system also applies an optimum amount of antiskating force.

 

Cogging is banished by our coreless DC servo motor

Cogging is the tiny fits and starts exhibited in the rotation of many electric motors. Our special servo motor has no core; thus cogging is banished. Platter speed is more accurate than ever. Reliable speed accuracy is further improved by our Double-Servo Quartz control system.

 

Up front controls are designed for one-touch fully automatic operation

A capable microcomputer, contained in a programmed-to-order LSI, coordinates all circuits and controls for error-free fully-automatic operation. Push a button and the automatic mechanism takes care of the rest; platter start, cueing, lead-in, lead-out and end-of-play shutoff. The-up-front controls are light-touch sensitive - truly luxurious.

Acrylite case, 4 mm thick dust cover.

Feather-touch On/Off micro switch

 

Generally speaking, manufacturers design a product and place great stress on cost performance and additional effort is paid as to where the compromise is made. In the case of audiophiles, importance is attached to what they seek or want to do rather than its cost.

This turntable Luxman now proudly announce is designed purely from the concept of audiophiles - slim and compact appearance, rugged construction resistant to howling and external vibration, arm base where one's favorite tone-arm could be fixed by a single touch and performance stability. Look at the internal construction and you will surely notice the above philosophy throughout.

 

Motor Suspension

The most unique feature of this turntable is the motor suspending structure. The robust chassis of aluminum die-casting integrates the tonearm base. For the upper panel, anodized aluminum of 3mm thick is used, which is, through rubber, fixed to the wood frame thus providing damping effect. Net weight is 13 kg (PD-121) and 11 kg (PD-131), which contributes effectively to prevent howling feedback or floor vibration.

A tonearm is not provided with the PD-121 (and PD-131). But the elaborate bayonet mount type tonearm base , similar in principle to that used in cameras, is adopted to ensure quick interchangeability of various famous tonearms with easy "one touch" operation

 

Unique Stroboscope

A unique idea is adopted for the stroboscope to ensure an easy and pleasant check of the turntable rotation. In order to make the stroboscope pattern very clear a black light tube is fired by very short duration pulses and a special "dayglo" paint has been used for the strobo markings. Further the line frequency indication can be identified by colour yellow for 50 Hz and yellow/green for 60 Hz.

 

Chassis, wooden frame and panel

Aluminum die-cast chassis with sufficient strength and weight, 3 mm thick anodized aluminium panel are firmly assembled together with rubber and elegant wooden frame with bumper effect which keeps this turntable immune from vibration

 

Insulator of Triple Structure

A special and unique insulator has been developed to ensure best possible anti-vibration. Each spring is damped by rubber, and the whole damper mechanism is suspended in silicon-grease. This is really and effective insulator and necessary compliance and damping effect are beautifully integrated.
