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.

Leak 3090 speakers

In Europe, home of some of the world's finest speakers, the Leak 2075 became recognised as a reference. Hardened professionals used this product as a yardstick by which other products were measured.

Enter the 3090 - the yardstick has grown.

The most dramatic improvement is the use of our patented Isodynamic tweeter. This is a flat-field unit, using no conventional coil, cone or dome. Instead, an ultra thin diaphragm with a printed circuit. This is activated by rows of miniature magnets made from Samarium Cobalt - the most powerful magnetic material known to man. The result - a response right up to 26 kHz -3 dB and possibly the best dispersion characteristics of any tweeter around.


 

The midrange is handled by two separate units. The upper midrange unit has holes in it. The precise positioning of these holes was worked out using laser-beam holography, so that delayed resonances are eliminated and this is one of the sweetest midrange units in existence. The lower midrange operates from 500 to 2000 Hz. About 40% of music power occurs in this band and the unit is built to take it - the cone is a sandwich of polystyrene and aluminium for great rigidity.

In the 3090, we have taken special care to make it right for any room, your room. Environmental Controls for Low Mid Range, High Mid Range and the ISO tweeter enable you to find the rigid tonal balance in the listening area and the swivelling upper cabinet means that these directionally sependant frequencies can be tuned to optimal dispersion for your favourite listening position.

Bass frequencies are handled by a 15" woofer,  made out of our unique sandwich of polystyrene and aluminium. The incredible rigidity of this unit means you get perfect piston-movement of the cone for real deep bass of the kind that only transmissionline cabinets can give you.

Linn Index loudspeakers

The Linn Index is a two way loudspeaker system, utilizing an eight inch bass driver and a one inch soft dome tweeter in an accoustic suspension enclosure. Even though it is a "budget" priced loudspeaker, the Index is intended for use by the serious hi-fi enthusiast. It offers what we believe is the best value-for-money available in an inexpensive speaker, in terms of parts quality, construction, and perormance.

Almost all lower priced loudspeaker cabinets are constructed of 1/2 inch or 5/8 inch particle board, often of a lower density than that used in larger loudspeakers. The Linn Index uses full 3/4 inch, high dnsity particle board, which results in a much more rigid enclosure. Likewise, speaker connectors are usually mounted on a pressboard insert, set into a cutout on the back of the cabinet, which greatly compromises cabinet rigidity. The index connectors are flush mounted directly into the cabinet, eliminating this problem. The connectors themselves are individually machined 4 mm banana sockets, custom manufactured by Linn Products, instead of the typical press-on connectors or binding posts. These connectors provide a vastly superior electrical connection. Along these lines, the speaker is wired internally with 20 amp, 50 strand cable, which is the same cable used in Linn's more expensive loudspeakers, including the DMS and PMS.

Each Index is individually tested on Linn product;s Hewlett Packard computerized test system.

Conrad-Johnson MV125 power amp

Vaccum Tube Power Amplifier

The Conrad-Johnson MV125 offers an unparalleled level of sophistication and refinement in music reproduction, but it cannot transform an inferior stereo system. Only the very best loudspeaker systems will be capable of fully revealing the capabilities of this precision instrument. Proper set-up is important in any high-fidelity system, but with state-of-the-art components it is essential. Given a system of high quality components, there remain a number of important details which must be attended to.

 

Absolute Phase

Musical notes are heard through the ear’s response to waves of alternating rise and fall of air pressure. Musical transients are exclusively positive: that is, the initial effect is a rise in pressure. The ear is capable of distinguishing these positive transients from the musically unnatural alternative of a negative transient (an initial fall in air pressure). In your stereo system, these transients are created by your loudspeakers. If the speakers respond to musical transients by first moving out, they are creating a rise in pressure, and the system is said to be "phase correct". If they respond by moving in, they create a fall in pressure and the system is said to be "phase inverting". Each component in the stereo system is either phase correct or phase inverting (including the cartridge and speakers-these are normally phase correct). Your MV125 is phase correct. It is of no consequence if an individual component is phase inverting, as long as the system as a whole is phase correct. This will be the case as long as the number of phase inversions is even (or zero). If your system has an odd number of inversions, then you must add one phase inversion. This is conveniently done by reversing the positive and negative connections on either your cartridge or your speakers (be sure to reverse both channels).

 

Circuit Design

It has been our experience that simple designs with few active stages when executed with care and great attention to detail will be both more musical and more reliable than overcomplicated alternatives. Accordingly, the audio circuit of the MV125 is remarkably straightforward. A triode input amplifier comprised of paralleled sections of a 5751 is direct coupled to a cathode coupled differential phase inverter using high

current triodes to provide balanced, low impedance drive to the push-pull output stage. The output stage features ultralinear operation of two pairs of 6550s for high power levels with reduced source impedance. As a result, the amplifier is capable of supplying the large current demands of high amplitude musical transients driven into reactive speaker loads.

A substantial main power supply of massive polypropylene capacitors enables the MV125 to easily meet these extraordinary current demands. Voltage regulators for the voltage amplifiers and phase inverters provide nearly absolute isolation of these sensitive stages from the output stages.

 

The MV125 uses twelve vacuum tubes of three different types: two 5751 (V1 and V2), two 6FQ7 (V3 and V4) and eight 6550s (V5 through V12).

Conrad-Johnson PV12 preamplifier

Vaccum Tube Pre-amplifer

The PV12 draws on two decades of research at Conrad-Johnson into the reproduction of recorded music. The result is a line-stage preamplifier with a remarkable ability to recreate the dynamics, textures, tonalities, and ambience of live musical performances. With the PV12, we believe that you will experience the excitement of discovery in hearing more from your favorite recordings than ever before.

The audio circuit of the PV12 uses six vacuum tubes of three different types: two 12AX7 (V1 and V2), one 5751 (V3) and three 12AU7 (V4, V5 and V6).

Absolute Phase

Musical notes are heard through the ear’s response to waves of alternating rise and fall of air pressure. Musical ransients are almost exclusively positive: that is, the initial effect is a rise in pressure. The ear is capable of distinguishing these positive transients from the musically unnatural alternative of a negative transient (an initial fall in air pressure).

In terms of your stereo system, these transients are created by your loudspeakers. If the speakers respond to musical transients by first moving out, they are creating a rise in pressure, and the system is said to be "phase correct". If they respond by moving in, they create a fall in pressure and the system is said to be phase inverting. Each component

in the stereo system either preserves the phase of the incoming signal, and is said to be phase correct or inverts the phase and is said to be phase inverting. It is unimportant whether an individual component is phase correct or phase inverting, as long as the system as a whole is phase correct. This will be the case if the number of phase inversions is

even (or zero).

Tandberg Fasett loudspeakers

Living Sound Fasett - new concept in loudspeakers

With the Tandberg Fasett all the advantages of direct and indirect sound distribution can be exploited. In the concert hall the sound flows out from the instruments in all directions. It spreads out in the room, partly beamed directly at the listeners and partly reflected as indirect sound from the walls, ceiling and floor. the total sound in a concert hall is therefore a combination of direct and indirect  sound. the strength of the indirect sound in comparison with the direct sound depends upon the hardness of the reflecting surfaces - the walls, ceiling and floor. The sound reflected from a hard surface (glass, concrete) is stronger than the sound reflected from a soft surface (curtains, perforated tiles). With the Fasett this living "sound picture" can be re-created in the home.

 

Play with sound

Tandberg stereo-amplifiers have outputs for 4 loudspeakers (two for each channel in the stereo installation). When these 4 outputs are exploited with 4 loudspeakers, the "sound picture" can undergo a distinct improvement both in mono and stereo. With 4 loudspeakers it is possible to experiment with a combination of direct and indirect sound. The Fasett is shaped so that it can be tilted and turned to many positions. If two loudspeakers  are beamed directly towards the listeners, the other two can be directed to the side;  the back or upwards against, for example, a hard wall or a ceiling. These two loudspeakers will provide the indirect sound.

 


Technical Terms Bass Reflex

The Fasett employs a principle known as bas reflex. Simply explained it means that the sound radiating from the back of the loudspeaker cone is directed through a tuned duct so that it radiates from the front. It thereby boosts the ordinary radiations from the front of the cone. In this way the bass response in a limited tone region is reinforced. A further advantage resulting from this principle is reduced distortion. Be aware that the siting of a loudspeakers in a room also affects the strength of the sound in the bass region.

Sensitivity

An expression for the electrical power (operating power) that must be applied to the loudspeakers to reach a sound level of 96 dB (loud orchestra level) at a distance of 1 metre.

Maximum continuous power

The power that can be continuously delivered to a loudspeaker system without causing damage as a result of a high temperature in the voice coil.

Music Power

The power that can be delivered to a loudspeaker (a loudspeaker system) for a very short time interval without unduly raising the temperature or the distortion.

JVC's L-E5 Linear Tracking Turntable is a masterpiece of miniaturization. Not only were our designers able to reduce outisde dimensions to little more than that of a record jacket (it's only 34 cm wide) but they were able to incorporate the most advanced and most accurate record tracking system in existence into its design. This actually contributed to the clean lines and unostentatious controls that make the L-E5 as much a pleasure to see as to hear.

 

Linear tracking eliminates tracking error, reduces distortion and produces clear sonic images.

The grooves in a phonograph record are the result of a parallel-tracking stuido cutting lathe and that's the way the tonearm of the :-E5 plays them back for yopu. Tracking error is eliminated and with it music marring distortion, intermodulation, crosstalk and poor separation. In the L-E5, a computer aided Electro Dynamic Servo system and a no-contact optical sensor keep the tonearm 90° tangential to the record groove from beginning to end of play.

 


Short low-mass straight aluminum tonearm with integrated dual-magnet cartridge.

The tonearm of the L-E5 is a studey in simplicity, its low-mass design reduces arm resonance and there is no need for the complex anti-skating compensation devices required by standard pivoted-tonearm designs. JVC's New Gimbal Support for the tonearm assures high sensitivity.

 

All tonearm movements are computer controlled via convenient front-edge controls.

The L-E5 is a fully automatic turntable with microcomputer controlled functions - lead-in, cue, return, or repeat. All controls are up front, outside the closed dust cover including the buttons that move the tonearm left and right for total hands-off control.

 

The coreless DC servo motor and JVC FG Super Servo.

Naturally the golden combination of two JVC technologies are employed to assure absolutely stable, cog-free speed accuracy.
