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.

Phase Linear 8000 turntable

Model 8000 Series Two Linear Motor Turntable

No other turntable can match the Phase 8000, because no other turntable has such advanced motors. You can't buy a quieter turntable. Or one with as low wow and flutter. Or one that tracks better.

The Phase 8000's tangential tracking tone arm keeps the stylus in perfect 90° tangent with the grooves. It's the same way the master disc was cut, so the motion of your stylus is identical to the cutterhead stylus. There's absolutely no tracking distortion. No crosstalk. No skating force that can actually re-cut your grooves.

 


New Linear Motor Eliminates Mechanical Linkage

Other manufacturers have tried to move tangential tone arms with worm gears. Belts. Rollers. All with the same sad result; Mechanical connections pass on the noise and vibration of the motor. The Phase 8000 solves this problem with an ingenious Linear Motor. The tone arm base is a permanently magnetized armature that glides along guide bars above electro-magnetic coils. The arm moves by direct induction - not mechanical connection. So there's virtually no noise. Inside the tonearm, an opto-electric detector cell senses the slightest tracking error, and instantly sends correcting signals to keep the arm on track.

Balanced sound reproduction from  a compact, highly-versatile speaker system is now yours with the Pioneer CS-66G. This smooth, clear-voiced system features three cone type speaker units in a three-way design. Its 10-inch (25 cm) woofer, 6,5-inch (16 cm) midrange and 3-inch (7,7 cm) tweeter reproduce the entire sound spectrum with natural fidelity. Low-distortion/rich performance is assured from any power input up to a maximum of 40 watts , thanks to its high efficiency and sensitivity. This multi-purpose sound system is perfect for use in the average-sized home or office setting for stereo or 4-channel. Its handsome enclosure with walnut grain finish is fitted with a removable, carved wooden grille. Thanks to its compact size, the CS-66G can be placed horizontally or vertically in bookshelf or cabinet-top locations to provide maximum sound dispersion.

 


10-ibch Woofer

A wide range of musical program sources, including those with heavy bass sounds, are handled with ease by the 10-inch woofer in the CS-66G. The so-called "clipping" of low-frequency sound is suppressed to reduce distortion and enhance richness. Since this woofer is especially designed to respond faithfully to signals as low as 35 Hz, it ranks among units in the 12-inch and larger class. It features a large power input capacity and delivers excellent transient response.

6,5-inch Midrange

The brilliance of brass and precision instruments, the richness of the human voice and the all-important middle frequency sound of a full orchestra come through with natural clarity and realism, thanks to the midrange speaker unit in the CS-66G. The back of the midrange is sealed tight to prevent interference with the other two speaker units.

3-inch Tweeter

Distinguished by its fidelity and linear high frequency response characteristics, the 3-inch tweeter in the CS-66G adds a clean, crisp feeling to all music. The overall sound of the CS-66G is further brightened by the exceptionally smooth transient response of this essential unit.

 

Crossover Network

As in all-multi-way speaker systems, the crossover network in the CS-66G goes a long way in determining overall quality. Pioneer has employed selected quality parts, including a large ferrite core, to create a special crossover network to handle the full audio spectrum with a minimum of distortion and damping loss.

Garrard GT-25 turntable

Features for feature, dollar for dollar the GT25 is superior to any turntable in its price range. The GT25 provides music reproduction on a par with the more expensive GT35 and incorporates many of the same features.

Yet, the GT25 costs no more than many of the manual turntables on the market today. The GT25 is an ideal component for the music lover who insists on performance without compromise, plus the safety and convenience of fully automatic operation - at a price that is economical.

The tonearm

The tiny stylus, as it traces the groove , must bear the weight of the tonearm. It is of critical importance that the weight of the tonearm be held to a minimum. The GT25's nine inch, tubular aluminum tonearm with magnesium headshell, weighs just 12 grams. It rides on the same low friction jewel bearings as the GT35. it will readily track records that are badly warped - something tonearms of higher mass simply can't do.

 

 

The motor

An advanced development of Garrard's time tested Synchro-Lab unit it combines an induction rotor for high starting torque and a synchronous section locked to the 60 sycle frequency of the power line. accurate speed is assured even when the voltage fluctuates. The precision bearings are of sintered bronze and are oil retaining. The entire motor is isolated from the turntable by special rubber bushings, ensuring freedom from vibration.

The platter

Die cast if the same special aluminum alloy as in the GT35, the platter is rotated by a precision-ground belt, isolating it from the motor . The platter is balanced and diamond turned during manufacture to achieve true concentric trim. These materials and manufacturing processes help to explain the excellent rumble, wow and flutter specifications of the GT25.

A 12 gram tonearm. The advanced Sychro-Lab motor A die-cast platter. A two points record support. The Delglide Automatic System. A specially designed base and dust cover. An unprecedented 3 year limited warranty including parts and labor. There are turntables in its price range that offer some of the features and specification of the GT25. the GT25 has them all at a price that makes it a best buy.

Garrard GT-35 turntable

The GT35 is a perfect example of meticulous engineering. Everything about it - its impressive rumble, wow and flutter specifications, its low tonearm mass and low bearing friction - confirm the visual and tactile impressions you get of high performance.

The tonearm

Garrard engineering has given special attention to this critical aspect of record play. The tonearm of the GT35 weighs just 12 grams, lower than any automatic turntable in its price range. The tonearm features an ultra-light magnesium headshell and jewel bearings ensure that the finest and lightest tracking cartridges will perform up to their maximum capability.

The motor

A DC servo-controlled unit incorporating electronic sub circuits in a self-correcting network. Rumble, wow and flutter specifications rival the finest turntables, including the expensive direct drive units. The GT35 motor rotates records at rock-steady speed with total freedom from AC vibration.

The platter

Dynamically balanced and die-cast from a special aluminum alloy, assuring uniform density. It is rotated by a precision-ground flexible belt, further reducing vibration. The GT35 specifications are well within the professional transcription category.

 

 

Variable speed

Electronic control with independent adjustments for 33-⅓ and 45 rpm. Correct speed is monitored by a stroboscope cast into the periphery of the platter. It is illuminated by an LED ( rather than the usual neon) resulting in a distinct image easily read, even in a brightly lit room.

Base and dust cover

Both the glass filled polyester  upper section and lower wooden section of the base form a barrier against vibration and resonance. Special shock absorbent feet minimize acoustic feedback. The dust cover pivots freely and can be raised and lowered even while a record is being played.

The Delglide Automatic System in the GT35 offers unerring accuracy and silent and sure operation. The combination of measured performance and features achieves the goal of its designers totally gratifying music reproduction.

Garrard GT-55 turntable

Generation Two Turntable with True Tangent Tracking

 

Since the first flat disc record was made, just about many year ago, audio engineers have been searching for a way to eliminate tracking error.

The master record is cut with a stylus that maintains a constant 90° tangent to the groove it is inscribing. Problem: play it back the same way . Anything else produces tracking error (maybe a little, maybe a fair amount), and that means distortion. In many years of search, turntable manufacturers have proposed an array of solutions. Some have been inventive, even ingenious; other have verged on the ridiculous. None until guide recently have been successful. Now there are there; all as different from any other turntable as the flat disc is from Edison's cylinder. Two of them solve the problem by a radical departure from traditional design; they move the entire tonearm across the record - pivot, counterweight and all.

Ingenious, Complex. And expensive.

Garrard found another way. Our half-century of turntable engineering culminated in a solution that retains the pivoted tonearm yet keeps the stylus in an absolutely true 90° tangent to the groove at every point from the record's outer rim right to the label.

Further, we did this with a computer-designed tonearm made of the ultimate in lightweight, rigid metals; magnesium. It has the lowest mass (14 grams) - and the lowest inertial drag - of any multiple-play turntable. And it is automatic. Fully automatic. Silky-smooth, silently automatic, and therefore gentler and safer than the steadiest hand, whether you use it as a single play or a multiple play turntable.

Garrard's solution - the GT55 - delivers other advantages, as well. Some small, some quite large, depending on what's important to you.

And one overriding advantage. The others sell for prices up to $700. the GT55 is under $250. which makes True Tracking not a costly privilege but an available benefit. To everybody.

 


True Tangent Tonearm

The computer designed True Tangent Tonearm keeps the stylus at a constant 90°  tangent to the record groove, by means of an articulated head. The angle between the head (holding cartridge and stylus) and the shaft of the tonearm changes with each groove. Thus, while the tonearm swings in an are over the record, the stylus is kept at a constant, true tangent. Tracking error is eliminated, with its consequent problems of record wear and harmonic distortion.

Tonearm

Made of modern, low-mass magnesium, the GT55'stonearm weight an astonishing 14 grams. It rides on jewel vertical pivots and horizontal ball bearings. Inertial drag and friction are reduced to absolute minimum levels.

Anti-skating protection on the GT55 is provided by a unique, patented system. Completely non-mechanical, it operates magnetically, and varies in proportion to the actual skating force across the surface of the disc. It is calibrated for elliptical and CD4 styli.

Cueing rate is variable, and the cueing operation is damped in both directions by the main cam of the turntable

 

The GT55 is the only belt-drive multiple play turntable with a DC servo motor. Both the motor and the belt-driven automatic mechanism are completely new. The speed of the motor is continuously governed and regulated by an electronic servo system. The automatic mechanism is smooth and silent in both single and multiple play. It is also completely disengaged from the tone arm when the record is playing.

Speed control is variable ±3%, and is electronically governed by the servo which controls the motor. Read-out monitored by an illuminated stroboscope.

The platter is four pounds, die-cast and dynamically balanced for smooth, precise rotation. It is driven by a flexible belt, which insulates it from any possible motor vibration.

The precision controls are conveniently grouped , and include selectors for single or multiple play, as well as a repeat-play option for use in either mode.

Meriton HD-540 cassette deck

The HD-540 features the Dolby System, designed to minimize annoying noise and tape hiss present in all tape recordings. A system so effective, it improves Signal-to-Noise Ratio 8 dB (from 50 dB to 58 dB with Dolby operating). The HD-540 with Dolby also reduces tape hiss level without effecting frequency response or adding distortion. The result : noise -free music. A rewarding experience.

Whatever the personal tape preference, the HD-540 is equipped for exceptional results with a tape bias and equalization control. This switch operates to change over the recording bias current, equalizer characteristic and recording level of the cassette deck depending on which type of tape is used; chromium dioxide, ferri-chrome or low/noise and high output or regular type cassettes. New ferri-chrome tape gives a wider dynamic range and less distortion producing a superior bass and middle frequency response.

 for greater frequency response, durability and matchless recording results, this is the finest tape head made. A single-piece-core construction tape head manufactured under exacting conditions. Especially critical today due to the wide use of high-density chrome dioxide tapes. The advantages of this ferrite head are wide dynamic range , low distortion, and a high Signal-to-Noise Ratio. It is also built for long wear.

Servo Motor

A solid state synchronous DC servo-motor with servo circuit is used in the HD-540 to ensure constant speed revolutions, long-life and reduce noise. Other benefits of this precision-engineered motor are minimal wow and flutter figure of 0,11%

Employed in the HD-540 is an electronic sensor mechanism that automatically stops the motor and releases which ever function control is engaged. This feature saves consider able wear on the tape head, while it helps to prevent undesirable sound effects such as wow.

A convenient device for either recording or playback, the pause switch instantly and temporarily stops the tape. Commercials from a station you are recording can be eliminated.

VU Meters

To increase the accuracy of tapes recorded on the HD-540, Meriton has designed highly efficient VU meters for each channel. Designed with scales marked to permit visual confirmation of louder signals made necessary by the wider dynamic range of the new types of tape.

Quick review and cue buttons, to a fast way to locate a particular section of the tape. Press the desired button and tape will move forward or reverse while still in play position

Elac Miracord 50H mkII turntable

At first glance, most automatic changers seem pretty much the same. A record drops, the turntable spins, a tone arm moves over to the record, where a stylus ( or needle) drops into the grooves. This sets off a chain of electronic impulses that ends up as music from your speakers. Any automatic changer will do all this.

An Elac Miracord will do it better. Every step of the way. Result; a fuller, richer sound from your records. In very simple terms, here's how we do it:

Start with the Elac tone arm. Its job is to hold the cartridge (which holds the stylus) and swing out onto the record. Most tone arms will do just that. The ones we build do just a litle more.

 to begin with, there's the tracking force. This is technical talk for the amount of pressure the tone arm brings down on your records. Naturally, the lighter the pressure, the lower the friction - and the more plays you'll get from each record and each stylus. That's why at  the base of the Elac tone arm you'll find a special little knob that lets you adjust the weight coming down on your records to less than one gram - or one twenty-eight of an ounce.

How many times have you tried to play a specific cut on an LP and dropped the tone arm either past the beginning of the tune either past the beginning of the tune you want, or into the ending of the song before it.

 

That can be hard on your ears, and even harder on your records. That's why we've come up with a cueing device so foolproof you can literally pick any groove on a record and ease the needle into it. Just flip a lever which gently raises the tone arm and lets it float with the stylus a hair's breadth over the record. Position the arm exactly where you want it, and flip the lever back. This operates a cleverly-designed, tiny piston which softly lowers the needle into the gtoove you've selected.

Which brings us to yet another example of Elac wizardry. The natural inclination for a needle on a record is to wear against the inside wall of each groove, (if you've ever heard a stereo record where the separation seems poor or the sound is distorted, this could well be the cause), Elac eliminates this inward drag with a special anti-skate device.

All Elac changers have push-button controls, positioned where they;re easiest to reach.

Everything is controlled by push-buttons, including the heavy-duty motor. Bearings are precision-made so you can forget about the annoyance of rumble and flutter. And life-time lubricants help keep maintenance to the barest minimum.

Everything we've mentioned so far is on every Elac Miracord. An impressive set of credits, to be sure. For some models, however like the 50H mkII its just the beginning.

 

Quite simply, the best automatic turntable money will buy. The 50H mkII contains a set of advantages that places it beyond the reach of any other charger in the world. With the variable speed control you can set the speed at precisely 33-⅓ or precisely 45 rpm, and a stroboscopic ring on the turntable will read out the accuracy of the speed. You may vary the speed by as much as three per cent either way. This not only assures you of exact control for normal listening, but also comes in handy for special uses such as dubbing sound home movies, or playing along with a musical instrument, where precise pitch is essential.

The 50H mkII is also a rarity in that you can now play your finest records and the precision arm will be lowered by the silicon damped cueing device, even in the automatic phase. A newly developed synchronous hysteresis motor reduces rumble to  an all-time low while maintaining a speed accuracy that is truly incredible. All told, the Elac Miracord 50H mkII represents the ultimate in automatic changers but to fully appreciate everything it offers you've really got to hear it for yourself.
