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.

Ortofon MC 20 Super II cartridge

A Completely New Design  - Inside and Out

As the fourth generation of Ortofon's best selling Moving Coil cartridge ever, the MC 20 Super II has a tradition as well as a reputation to live up to. Very conscious of this, the Ortofon engineering team has carefully evaluated every detail and available technology, to create a cartridge which, will deline the standard of sound reproduction in its class.

 

Fritz Gyger Type 1 Stylus With Improved Geometry and Ultra Stable Imaging

The FG Type 1 stylus benefits from the latest technological advances within diamond cutting and polishing. It is now possible to produce a very slim profile which will track even the highest frequency groove information. This is particularly important for the innermost turns of the groove. At the same time, the FG Type 1 stylus is distinguished by a larger than normal footprint for reduced distortion and record wear.

The audible results are crystal clear - a convincing and natural reproduction with a very stable definition or width and depth in the musical perspective.

 

The Ortophase Concept Adds a New Dimension to Analogue Sound

The inherently phase linear characteristics of the FG Type 1 stylus are further emphasised by the proprietary Ortophase concept which was introduced in Ortofon's famous MC 2000 cartridge.

Statistically reliable listening tests and extensive laboratory studies have demonstrated the importance of phase linearity in the reproduction of high quality audio.

But it has taken Ortofon's experience and manufacturing technology to make cartridges phase linear. Since a cartridge is a bandwidth limited transducer, a ruler-flat frequency response will not produce phase linear characteristics. Ortofon's research has shown that a very carefully calculated shaping of the amplitude response will result in a linear phase response.

This is the reason why frequency charts for the MC 20 Super II , show a slightly rising level above 5 kHz. Normally, such a response would be interpreted as a result of uncontrolled resonances. In fact, the natural resonances are under full control, and every Ortofon Moving Coil cartridge has been tuned by hand to ensure that it precisely meets the specifications of the Ortophase concept.

 

Non-Resonant Aluminium Cartridge Housing Prevents Sonic Colouration

The sound of the MC 20 Super II also benefits from Ortofon's new aluminium cartridge housing.

Internally, the magnetic assembly is securely screwed and glued to the body, and the precision fit of the two anodised extrusions makes the entire housing acoustically inert.

The large, solid upper plate makes it easy to achieve a perfect mechanical coupling to any high quality shell.

 


Specifications:

Output Voltage:  0,2 mV (1 kHz, 5 cm/sec)

Channel Balance:  less than 1,0 dB

Channel Separation:  better than 25 dB

Frequency Response:  20 - 40,000 Hz +4 dB -1 dB

Tracking Force:  1,6 - 2,0 g

Tracking Ability:  better than 90 µm

Ortofon MC10 Super II cardridge

A Level of Quality You thought you Couldn't Afford

 

Compatible with most High quality amplifiers - Like the other higher output Moving Coil cartridges from Ortofon, the MC 10 Super II produces sufficient output voltage for the MC inputs of better audio amplifiers.

 

For more than 50 years music lovers and audiophiles all over the world have appreciated the unique sound quality generated by Ortofon's Moving Coil cartridges. Music lovers have chosen this particular design for the simple reason that it gives them greater listening pleasure. And audiophiles have praised the portrayal of space, and precise image location, plus the richness and purity of detail.

Many have asked the question: why is the sound of a Moving Coil cartridge so superior to that of a traditional magnetic design?

The answer, in one world, is linearity. The patented Ortofon low-impedance, low-output design is inherently linear over the entire audible range. And over the years, numerous enhancements developed by Ortofon have further increased the linearity of Moving Coil cartridges and eliminated still more sources to sonic colouration.

Even the least expensive member of the new MC Super II generation - the MC 10 Super II - incorporates a highly advanced diamond stylus, the Wide Range Damping System, the Ortophase concept and several other advantages, originally developed for top-of-the-line Ortofon cartridges. These technologies are also described in more detail in connection with the MC30 and MC20 Super II.

 

Outstanding Tracking Ability at All frequencies and levels

The tracking ability of a cartridge begins at the point of the stylus. In the case of the MC 10 Super II, the stylus is a nude Fritz Gyger Type 2 diamond which features a very slim profile, and a relatively large footprint.

These qualities mean that even high frequency modulation in the innermost turns of the groove will be reproduced accurately - at a lower tracking force than normally associated with Moving Coil cartridges.

Furthermore, the ingenious metal disc that is the heart of Ortofon's Wide Range Damping System ensures optimum damping of the Cantilever movements at low as well as very high frequencies. This is one more reason why the MC10 Super II will accurately track the violent modulation from a bass drum, as well as reproduce the delicate timber of a harpsichord.

JBL L100T loudspeakers

JBL Speakers for Accurate Sound Reproduction

The accurate reproduction of sound requires different physical demands upon a loudspeaker. The deepest bass frequencies, especially at high volume levels, require the speaker cone to travel quite a distance in order to move the necessary amount of air. Conversely, high frequencies require a diaphragm that can move much more rapidly, over shorter distances. The choice of capacitors, resistors, inductors and the circuitry in speaker design is of critical importance to the  resulting sound.

In the "L" series, the same speakers that are auditioned by engineers and producers while recording - the speakers by which the quality of the sound is judged by the professionals throughout the recording process - are here for the home environment. The "L" series from JBL.

 

JBL's top-of-the-line three-way , floor standing system reproduces sound equivalent to first generation sources - compact discs, master tapes and high performance pressings, possessing a sensitivity of 91 dB at 1 Watt/1 meter, a continuous power rating of 200 Watts, and dynamic power rating of 800 Watts (peak IEC shaped noise).

JBL L80T loudspeakers

Engineering Expertise

There are basically two ways for a company to build a loudspeaker system. The most common method is to buy the component parts from mass suppliers and assemble them, accepting the inevitable compromises which result from using off-the-shelf components.

JBL has a better way. For nearly forty years JBL has designed and built the entire system, form the initial computer calculations to the finished product. All variables are controlled so design goals never have to be compromised. Better engineering is the JBL approach to better sound. At JBL engineering takes many forms; Component design, testing of materials, manufacturing techniques and electronics. JBL always seeks new and better materials and subjects them to thorough examinations, including detailed vibrational analysis and magnetic measurements. A fully equipped tool and die shop is maintained to enable JBL to manufacture equipment with tolerances as close as two ten thousandths of an inch. JBL measures and analyses tone bursts, impulse response and phase response with the use of state-of-the-art. Time-display spectometry, Fourier analysis, and other advanced techniques. For the most accurate measurements conceivable, JBL employs a wide variety of specially calibrated condenser microphones, in addition to testing in their own anechoic chamber. Human ears still remain JBL's most sensitive measuring instrument. Every design is subjected to extensive critical listening by a panel which includes audiophiles, recording engineers and musicians, throughout a product's development.

 

The JBL L80T , a three-way floor standing system, yields unparalleled sound reproduction with its combination of a pure titanium high frequency transducer (O35Ti), laminated high polymer cone mid-frequency transducer, 10-inch Aquaplas low frequency transducer and High Spatial Identification Dividing Network. The L80T has a sensitivity of 90 dB a 1 Watt/1 meter, a continuous power rating of 150 Watts, and a  dynamic power rating of 600 Watts (peak IEC shaped noise). With its extended frequency response, ability to deliver original dynamic range and the re-creation of the full sound stage, the L80T sets the stage at home.
