High-Fidelity Stereo Headphone Set

The virtues of being alone have long been underrated. Or ware until Sansui decided to do something really meaningful about it. Now enter the SS-10 stereo headphone set, affectionately dedicated to those purists to whom stereo is indeed a very personal experience, ideally savored in princely solitude, far from the maddening crowd. Equipped with newly developed mechanical two-way speakers, this truly high-fidelity set reproduces a wide range of frequencies from very, very low to ultra-high with uniform smoothness. Few other stereo headphones on the market today are so discreet and so solicitous of your undisturbed listening pleasure. The SS-10 "direct line" set offers a host of attractive features, including separate volume controls for each channel, identical left and right channel characteristics, and hand-sewn so comfortable that it's a very wise investment from that standpoint alone. But Sansui is also very understanding about the pleasures of stereo sharing, and providently thought to make the "direct line" convertible to a "party line". So that on those occasions when there's something special you'd like someone special to hear with you, the SS-10 has a two-meter long Y-shaped extension cord equipped with two jacks for connecting two sets of headphones. But whether used in solitude, or adapted for sharing, the SS-10 stands alone as today's best buy in stereo headphones.

Mechanical 2-Way Speakers

The unique, newly developed mechanical 2-way speakers of the SS-10 utilize large 8 cm, special cone papers for the low and middle range notes, and quality polyester diaphragms that also cover the high ranges. These enable the SS-10 to reproduce sound with an absolute minimum of intermodulation and harmonic distortion and a maximum of transparency and resolution.

Wide Frequency Range

Thanks to the mechanical 2-way speakers, the SS-10 reproduces a wide 20 to 20,000 Hz range of sound, from well-damped, powerful rich heavy bass comparable to that reproduces by large speakers, to delicate, transparent treble, all with exceptional smoothness.

Identical Channel Characteristics

The SS-10 is designed to minimize the difference in tonal quality and output sound pressure level between the left and right channels, enabling you to enjoy well-balanced stereo sound. Further, unlike speaker systems, a stereo headphone set completely separates the left and right channel sounds, so that the stereo separation is exceptional.

Separate Volume Controls

Equipped with a volume control on each ear pad, the SS-10 saves you the trouble of standing up and walking over to the amplifier each time you wish to adjust the sound volume. It;s especially convenient when you are sitting far away from the amplifier using the extension cord supplied.

Since the left and right channels can be separately adjusted , adjustment of stereo balance is also easily accomplished.

y-Shaped Extension Cord with Two Jacks

The SS-10 comes complete with a 2 meter long extension cord to let you relax away from the amplifier or tape deck. This cord is provided with two jacks for connecting two stereo headphones sets, so two persons can listen together.

Spiral Cord

The connection cord of the SS-10 is of the same curled spiral type as that used with telephones. Though as long as 3 meters, it never gets in your way.

Hand-Sewn Ear Pads

Made of specially-treated soft plastic, the SS-10's ear pads cover the ears very softly and do not exert uncomfortable pressure on the wearer. These comfortable pads seal out external sound and will not tire the wearer even after hours of continuous listening

Easy-to Use, Functional Design

The length of the head band can be freely adjusted to suit the size of the head or ear positions of each individual.

Omni-Dynamic Stereo Headphones

Sansui gives stereo music listeners the rich bass of dynamic acoustic transducers as well as the wide frequency range and brilliant musical reproduction qualities of the electrostatic types in these all-new, smartly designed SS-100 stereo headphones.

"Omni" means that the diaphragms inside the comfortably fitting earpieces each distribute a uniform driving force over its entire flat surface, avoiding split vibrations. The low mass of each diaphragm also means less total harmonic distortion and less phase distortion - the same advantages you have with electrostatic drivers. But since the SS-100 design is essentially dynamic , no electrostatic adaptor or special amplifier is required, and you enjoy a natural yet powerful bass reproduction as well.

With the Sansui Omni-Dynamic SS-100, frequency response is flat over the entire musical spectrum from superlows to ultrahighs. Harmonic distortion is minimal, impedance is flat with no trace of peaks or dips, and your amplifier or receiver is shown off at its best without overstraining.

Omni-Dynamic Principle

These handsome, Sansui-exclusive headphones employ an omni-dynamic transducer (diaphragm) in each earpiece. The units are made of polyester film, stretched to a uniform tautness and contained between two anisotropic magnet plates (Fig.1.) On the diaphragm film is etched a voice coil pattern (Fig. 2) And each of the magnet plates has a field (Fig. 3) which, when activated by the plus and minus pulsations of the musical input signal, moves the diaphragm to end from based on Fleming's left-hand rule as applies to current flow in coils.

Driver Construction

Omni-Dynamic Driver

As they are very thin and low in mass, the diaphragms offer excellent transient characteristics over a wider frequency range than can those shaped as cones or domes. This means you have a flat response from the superlows to ultrahighs with any musical input signal. Omni-dynamic drive means, too, that all sections of the diaphragm surfaces move in linear piston motion, without split vibrations, thus reducing harmonic distortion and extending dynamic range.

Powerful Magnets

The anisotropic magnet plates in the SS-100 each have high magnetic density to afford the headphones the very high sensitivity (efficiency) of 94 dB/mW.

Optimum Amplifier Load

Since the impedance of these headphones is literally constant at all frequencies, your amplifier or receiver is asked only to deliver an optimum load, meaning that you are assured of the best sound quality from your unit

No-Adaptor Design

To drive the SS-100 simply plug in the provided jack at the headphone outlet on your amplifier or receiver. No AC power booster or other adaptor is required.

Fatigue-Free Design

Comfortable Wearing

Eight neoprene supports separate the earpiece from the headband assembly, increasing wearing comfort. The earpads are soft and slim-silhouetted for further comfort, and the recess inside each is shaped to optimize air compliance for better musical reproduction, even into the very high frequency range.

Clear Channel Identification

You'll never confuse front and back or left and right two clearly-marked arrows point to the front of the headset, and only the left earpiece has a cable cord, both for channel identification and wearing comfort.

Slim Design Throughout

Since these Sansui-exclusive Omni-Dynamic drivers themselves are flat, thin and compact, the earpieces have been designed to present a slim silhouette. other design elements take up this low profile motif to result in a modern and quite comfortable stereo headphone set you'll enjoy for long years of hard use.

Automatic Direct-Drive Turntable

Sansui wants everyone to enjoy hi-fi music with the minimum possible noise, distortion and inconvenience. That's why the Sansui SR-535 automatic direct-drive turntable puts the emphasis on pure hi-fi performance and true handling ease. Accuracy of platter rotation, and a strong, anti-howl construction characteristics in the musical department. The direct-drive motor is a high-torque type and the special tonearm has a unique support to ensure delicate performance. Record reproduction is always clean and pure.

One simple control, the Auto/Manual Play Lever, does all the work. Put a record on the platter, set the record-size selector and pull the lever once; the tonearm is lifted, moved and gently lowered to the lead-in groove, when the record ends, the arm is returned to its rest and power shuts off automatically. The same lever permits manual play when desired. More convenience is offered in the Repeat facility permitting you to select one to five replays, or infinite replay.

Automatic Operation

One control knob does it all. The jumbo-sized Auto/Manual Play Lever has three positions of Manual On, Off, Auto Start/Stop. For a single automatic play, you simply place a record on the platter and gently pull the Auto/Manual lever into the Auto Start/Stop position. The tonearm lifts automatically as the platter begins to spin, the stylus is placed over the lead-in groove of the record, and the tonearm descends to begin play. If you desire to interrupt play at any time, simply pull the lever again, or you may wait till the record ends. In either case, the arm is automatically lifted  and returned to its rest, and power is switched off, all without your assistance.

When manual play is desired, simply set the control lever to the Manual On position. When the platter begins to rotate, move the stylus to over the part of the record you want to hear. An oil-damped Cueing Lever is provided to help you avoid damaging your valuable records. As in Auto Play, the Manual position on the lever allows the automatic return mechanism to return the tonearm to its rest.

Additional convenience Auto Repeat control on the SR-535.

In the Off position if sets the turntable in auto-return mode. Or, you can select from "1" to "5" repeat plays, or "infinite" which allows the automatic mechanism to continuously repeat its simple job until you change the repeat control settings.

Accurate Drive System

Sansui engineers have done if again. The platter of the Sr-535 never shows any appreciable slow-down under reasonable loads. This means that your 33-⅓ and 45 rpm records are always played at the correct speeds for best musical performance. This accuracy is assured by an advanced, high-torque, 20-pole/30-slot brushless DC type servo motor for direct drive. Speed drift is effectively eliminated by the Sansui-exclusive rotor position sensor mechanism, coupled with the motor's bias-controlled saturable core (Sansui Pat. Pend). Thanks to the dependable power supply, the drive voltage is kept constant for accuracy under any conditions.

Mechanically, as well as electrically, the SR-535 has impressive precision. All components and parts are designed, machined and assembled under very careful super-vision to live up to Sansui's strict quality control standards. The bearing sleeve is mirror finished for complete roundness, for instance. The motor shaft/center spindle is formed of the finest polished carbon-chrome steel and rides in a thrust bearing of tough friction-resisting synthetic polyamide. We've used a special lubricant, one developed by the aerospace industry, to ensure low friction in the motor over long years of operation.

Smoother rotation is also ensured by the heavy (1,4 kg ) aluminum die-cast platter. This, plus Sansui's attention to every minor point in design and construction, gives the Sr-535 impressive specifications low 0,038% wo/flutter and better than 67 dB rumble.

Fine speed adjustment with strobe

On the edge of the oversized (31,8 cm or just over 12-inch) platter there are four rows of stroboscopic patterns, two each for both speeds to permit fine adjustment when your electrical power is either 50 Hz or 60 Hz. The strobe light illuminates the platter edge so that you can visually check its rotation speed for accuracy. Once the correct speed is reached, the speeds will continue to spin accurately, or you can use two fine speed controls to vary platter by as much as ±3,5% from the standard speeds. By the way, these controls are recessed to avoid accidental speed change.

Stabilized Tonearm

Exceptionally high tonearm stability is one of the reasons the Sansui Sr-535 performs with such high musicality. Despite the attractive price of this fully automatic turntable, the tonearm has the same stability and resistance to resonance found in much more expensive models. Spurious vertical travel and harmful torsion or twisting are avoided by a special support with two vertical pivots. The mass of the arm is concentrated at these points to clearly define the unit's fulcrum for better mechanical advantages, particularly in the bass frequencies which are delivered from your record free of "mud".

Low-resonance design

Resonance is further suppressed by the special acoustic absorbent, we use inside the highly rigid tonearm tubing. Then, we've decoupled the balance weight from the arm shaft vis a newly designed rubber damper. All types of vibration whether  transmitted through the air or through the physical structure, are shut out before reach the stylus.

Other tonearm features:

Zinc-alloy die-cast arm base; a massive heavy structure to improve bass response by firmly securing the arm to the cabinet.

Direct readout tracking force dial; precision-calibrated markings every 0,25grams one rotation covers 0-to-3 gram range

Gold-plated connection pins; free from all forms of rust to ensure maximum transfer of the tiny electrical signals from cartridge to your amplifier

Arm lifter lever; oil damped for smooth operation

Anti-skate knob; adjustable even as the record is played, another bonus in this attractively priced turntable.

Cabinet

Sansui designers take special pride in the clean, modernistic looks of the SR-535 turntable. The silver metallic finish sets off the precision lines of the cabinet and is just "flat" enough to resist glare from room lights without appearing too dull. The clean lines are more than good looking, advanced computer technology and time-tested carpentry techniques alike were used in designing the Sr-535 to resist acoustic feedback or "howling". The automatic mechanism is mounted on a separate chassis inside the cabinet for instance while the low-profile of the base and its complex suspension system further ensure good sound.

Complex-suspension

To defeat all types of vibration before they can harm your music, the SR-535 is suspended in a complex system of rubber and spring devices. Air-borne vibration, such as sound-waves from your speakers, and structure-borne vibrations, such as originating from your operation of amplifier or receiver controls, from footsteps, etc. Are effectively damped so that your music retains its tight bass, clean mids and crisp highs.

Electronic Automatic Transcription Turntable

Stereo purists who still claim only a manually-operated turntable can faithfully reproduce disc recordings without strain have some catching up to do. For here is a turntable - a fully automated transcription turntable - which performs with the ease and stress-free operation of a first-class manual but has the convenience and practicality of an automatic as well. The Sansui FR-4060 very efficiently eliminates the one major disadvantage of the complicated :changer-type" turntable by employing a non-mechanical, purely electric device, the galvano-magnetic detection mechanism, to detect the end of a record and prepare the tonearm for automatic operation. It makes it possible for the tonearm to ride completely free of stress-producing mechanical linkage systems until it is time for the automatic lead-in, return, repeat or cut operations to take over. In this way, the stylus is protected from distortion-producing lateral thrust, your records are safeguarded just as they would be on a manual, and since the tonearm is free, it can be moved to any part of the record manually, even during automatic play.

The Frequency Response-4060 features an unusually sensitive S-shaped tonearm, a newly developed Sansui SV27 magnetic cartridge with superb tonal characteristics, a special low-capacitance output cable, floating-mount base and platter design and many other original Sansui quality details. It is also fitted with a connection socket for the Sansui SRC-6 control unit (optional) for full remote-control of all automatic functions.

Those stereo purists who maintain that a manual turntable is the epitome of perfection have only to check out the FR-4060. by adding the convenience of automatic operation to one of the finest precision manuals ever created. Sansui has come up with a turntable to fully satisfy your specific needs.

60 W Power Handling, 90 dB/W Efficiency and 45-20,000 Hz Frequency Range

There are speaker systems a hundred times the size of the Sansui J33 which can't offer nearly the sound quality. Power handling capacity is 60 watts, an advantage ordinary small speaker systems can't equal. Efficiency is an excellent 90 dB/W at one meter, meaning you can drive the J33 with a relatively low-powered amp or receiver without problems of lost dynamic during the loud passages. Then, to ensure that you get your music's worth when you play any true high fidelity source, the frequency range is a wide 45 to 20 kHz - strictly hi-fi , right systems - staggered from the center axis to the left and right respectively - are on the "outside" for ideal response in your listening area. The staggered arrangement of the speaker units within each system assures pinpoint stereo imaging.

Two-way Design and Mirror-Paired Units for Incomparable Stereo Imaging

Sansui packages the J33 in matched stereo pairs; we suggest you mount them so that the tweeter of the left and right systems - staggered from the center axis to the left and right respectively - are on the "outside" for ideal response in your listening, area.

The staggered arrangement of the speaker units within each system assures pinpoint stereo imaging.

Luxurious "Piano" Finish on a Compact Speaker System

The Sansui J33 is finished in a deep black luster much in the same way a fine piano is finished. First the surface on the high-density enclosure panels are filled, then two layers of special lacquer are applied, again sanded smooth. Three more coats of lacquer are applied,, again sanded with care, filled, then wax-buffed to a high shine. The entire process takes nine separate steps, and results in an enclosure surface so smooth and hard it can resist nicks and scratches to retain its beautiful luster over the years.

Precision Panel Joining Means Ideal Air-Suspension Performance

Here's one of the secrets of the realistic bass response in the j33 - air-tight enclosure cabinetry that acts as a "spring" to reinforce the rich resonance of the low frequency musical sound waves produced by the woofer. To enclosure solid joints, Sansui craftsmen use a "plain miter Joint" technique, angling the edges of the enclosure panels and fitting the corners with extreme precision.

Seamed-Sheet Cone Assures Deep Musical Bass in 21 cm Woofer

The uniformly distributed mass and even thickness of the cone materials offer ideal density without adding unnecessary weight. Shape, too is important here, for the woofer cone is not straight but curved - formed by seamed-sheet technique which discourages distortion of all kinds. Ideal internal loss contributes still more to rich bass response.

The cone is then suspended by a rolled surround for ideal compliance, retaining its mobility even at high-level driving. Response is smooth whatever the level because the magnetic circuit features a large-sized ferrite magbet forming an exceptionally strong magnetic flux along the specially-treated, low-mass voice coil. High power handling, unusually high efficiency for a compact and believable bass reproduction are the advantages.

One-Piece Soft-Dome Tweeter Spreads Crisp Highs

Soft-dome tweeters, such as that in the Sansui J33 are known for their ability to avoid "beaming". That is, their output is radiated evenly in an expanding arc pattern to reach every corner of your listening room. Our soft-dome diaphragm, formed of polyester fiber of ideal firmness and elasticity, is damped by a uniform coating of acrylic-based chemical agent to effectively control harmful resonance while assuring linear response to varying input levels.

The dome is formed with a rolled surround all in one piece. Tonal degradation, caused when domes and surrounds are separately manufactured and bonded together, is thus avoided. Heat and distortion, too, pose no problem. This is because we use a 13,000 gauss magnetic circuit, a light voice coil and a rigid voice coil bobbin.

World's First "Mini" Speaker with Passive Radiator for Double-Rich Bass

Sansui has solved a big problem in little speakers. We custom-designed a passive radiator unit for the miniature 2-way, 2-speaker J11 system. It effectively restores the realistic rich bass sound which most other "minis" forfeit for their small size.

Double-rich bass isn't the only advantage in the J11. nor is its small size - no taller than a wine bottle or much wider than a paperback book - the feature you'll appreciate most. Where Sansui audio technology really shows up best is in the distinct sound image reproduction from this unique system - strictly hi-fi in every respect.

The surprising depth of the bass is complemented by natural sounding midrange and crisp highs for tonal balance. Bearing in the high frequencies is no problem since the newly-designed dome tweeter disperses its sound waves uniformly over a wide arc. The special design of the solid aluminum enclosure also adds to the big-hearted authority of this modestly sized "mini" from Sansui where it's all hi-fi.

Light and Firm Diaphragm for Tight Bass from 10 cm Woofer

It follows that if the passive radiator is to deliver authentic sound reinforcement from the woofer, the woofer itself must be of the highest performance standards. Here we've developed very special cone paper by mixing two different types of acerose pulps to achieve lightness, firmness and strength. The woofer cone, 10 cm in diameter, weighs only 0,6 grams, yet can respond faithfully to amp inputs over a wide frequency range.

Linearity in the woofer is further improved with the use of a separate, resin-formed surround. Distortion particularly in the second harmonics, is never noticeable, even during high-level reproduction, since the large magnet offers a huge 9,000 gauss field, uniformly distributed by the precision machined pole piece. The voice coil bobbin is highly heat resistant for constant performance, another assurance of excellent performance in all practical audio situations.

Soft-dome tweeter has Polyester-Based Cloth Diaphragm Large magnet

What are the three major benefits of the soft-dome design in tweeters. One, wide dispersion without "beaming". Two, low resonance to avoid distortion. Three, crispness and musically in the high frequencies. These, crispness and musically in the high frequencies. These add up to explain the popularity of soft domes, especially in "mini" systems. But we've added a fourth important benefit in outs, a better Signal-to-Noise Ratio by forming the one-piece diaphragm/rolled surround of responsive but firm polyester based cloth, damped by an acrylic-based agent, this construction avoids the use of chemical agents in binding the core to the surround, and thus prevents tonal degradation. To achieve transparent highs extending well into the supersonics, we've given this remarkable tweeter a powerful 9,000 gauss magnetic, flux, combulling phase irregularities by mounting an acoustic equalizer behind the diaphragm.
