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.

Tannoy Dover loudspeakers

Dual Concentric Time Compensated Loudspeaker System

The famous Tannoy Dual Concentric in a modestly sized cabinet that can be floor standing on its own plinth, mounted on speaker stands or a bookshelf.

A 10-inch (254 mm) version of the Dual Concentric drive unit is used in an infinite baffle (unported) cabinet, with rigid bracing and graded acoustic foam damping, to give the best possible sound reproduction in a loudspeaker of this size.

Each Dover is supplied with a separate plinth. If used as a floor standing loudspeaker this plinth can be attached to the base of the cabinet with the screws provided. When used on stands or shelves this plinth is not required.

The Dover is designed to provide the high quality sound of the Tannoy Dual Concentric system in a size of loudspeaker to suit smaller listening rooms.

The high quality of sound reproduction is matched by the standard of cabinet construction. Every Dover is finished in genuine walnut veneers, oiled by hand and the baffle is covered in real cork.

 


The Tannoy Dual Concentric is, therefore, a true single point sound source loudspeaker system which eliminates unnatural time delay, and provides the smooth consistent intensity of sound necessary to create a precise stereo image.

Tannoy Mercury MkII speakers

The Mercury MkII loudspeakers share the advantage of high power handling and sensitivity with low distortion and smooth frequency response - qualities which have ben the hallmark of Tannoy high fidelity loudspeaker systems for many years.

 

 Loudspeaker Enclosures

To provide optimum performance a loudspeaker cabinet must be rigidly constructed and acoustically treated. The Mercury MkII is constructed from high density particle board lined with an acoustic material to absorb internal reflections and eliminate standing waves. The cabinet is internally braced at antinodal points to minimise cabinet resonance and colouration and the narrow front profile ensures good horizontal dispersion. Low frequency loading of the system is provided by a carefully designed ducted port which reduces distortion and extends the bass response. Each loudspeaker is fitted with a detachable grille of acoustically transparent cloth stretched over a wooden frame.

 

 Drive Units

High frequencies are produced by a polyamide dome treble unit which combines a very smooth response with low distortion and wide dispersion and gives a finely detailed sound. A magnetic cooling Ferrofluid is incorporated and combines high power handling capacity with reliability and protection against sudden overload transients. The asymmetrical front plate is sculptured to improve reproduction by reducing diffraction effects.

Low and midrange frequencies are reproduced by a 200 mm polyolefin cone unit. This cone material gives a very smooth frequency response with negligible colouration. A newly developed cone/coil apex configuration provides a very rigid construction at the point where the cone is driven by the 4 layer high temperature voice coil.

 


Crossover Network

The crossover network receivers the electronical signal containing the fill frequency spectrum from the amplifier and divides it between the bass/midrange unit and the soft dome treble unit. We use only high quality components, including low loss solid dielectric capacitors and generously rated resistors and inductors. All components are hard wired and internal wiring is by heavy duty cable to minimise signal loss. All components are securely mounted to ensure maximum reliability and freedom from resonance.

 

Amplifier Power

In our loudspeaker specifications we recommend a suitable range of amplifier powers. The peak power handling capability of all Tannoy Loudspeakers will allow higher amplifier powers to be used with wide dynamic range material. Care must be taken with all amplifiers, irrespective of power output, to avoid abnormal conditions such as switch on surges or amplifier overloading (clipping and distortion) which may result in peaks of power greatly in excess of the specified ratings, and possible subsequent damage to the loudspeaker.

Features:

High-efficiency D-D Linear Torque Motor - wow and flutter below 0,035% (WRMS)

Super-solid resin cabinet with revolutionary "Space Saving" design

Fully-adjustable insulator feet

High-sensitivity J-shaped tonearm

Viscous-damped cueing

Full Front Operation

Variable pitch control ±3%

The pitch control knob provided lets you adjust the player's rotation precisely to the standard 33-⅓ or 45 rpm speeds, but there's another big advantage; pitch can be changed by as much as plus or minus 3 percent. Use this control when accompanying the record on your guitar or other instrument, or to vary musical pitch according to listening preference.

 

Easy-to-read stroboscope design

To add to the AP-2300's clean, simple appearance, the stroboscopic markings along the platter have been reduced from the usual 4 rows to 2. when employing the pitch control to adjust rotation speed, the knob should be moved until the upper or lower row of markings appears to be standing still. This indicates precise setting to the 33-⅓ and 45 rpm rotation speed , respectively.

 

Exclusive "Rec-Sync" disc-to-cassette automatic recording mechanism

The Ap-2300 was designed for use with other Aiwa component, but goes a step beyond mere matching for appearance sake; by connecting the cord provided with the unit from the special "rec-sync" jack at the rear panel of the AP-2300 to most Aiwa cassette deck models, player-to-cassette recording can be commenced automatically in tandem with the lowering of the played tonearm of the disc. Synchronized recording operation - it's another reason why Aiwa -built components work superbly together as well as separately.

Adcom GFA-545 power amp

Adcom GFA-545 represents the most advanced thinking in audio amplifier design. At 100 watts per channel, the GFA-545 offers an exceptional value; superior performance at a reasonable price.

Some of the outstanding features of this amplifier are:

100 watts per channel, 20 Hz - 20 kHz, into an 8 Ω  load with both channels driven with less than 0,09% Total Harmonic Distortion.

The ability to drive low impedance loads

Large Heat sinks to dissipate heat from the power transistors

External and internal fuses which are designed to protect your loudspeakers from possible damage and also to protect the amp itself under all but the severest abuse of operating conditions.

A thermal cutoff is also employed to protect the amplifier under high temperature conditions.

Instantaneous Distortion Alert which indicates when distortion products are above the 1% level.

 

The instantaneous Distortion Alert is a unique distortion detection circuit which reads all forms of distortion - T.H.D., Intermodulation DIstortion, Slew Induced, and DC-offset, peak LEDs, one per channel, will glow when distortion is above 1% regardless of the load impedance or reactance in use, the LEDs may occasionally flicker under high volume listening. It they glow brightly or are on most of the time that you are listening, you are overdriving your equipment and should turn down your volume control.

 

The GFA-545 is a truly significant contribution to the advancement of sound technology. To ensure that the quality of construction is on par with the quality of the sonics, (a much neglected area in many other amplifiers) the GFA-535 has been carefully developed with computer controlled metal fabrication techniques that maintain 0,005 of an inch tolerances throughout.

A preamplifier receives the signal input from your device (music source), and applies tone controls to that signal. You have more control over your audio playback in terms of bass, treble, volume, and more. When Fidelity IQ (Auto Loudness function) is turned on, the system automatically provides optimal audio playback according to any volume in conjunction with the master volume (This function operates independently of Tone Control and can be used in conjunction with Tone Control / Parameters are generated for the viewing environment using the setup microphone during initial setup). This Fidelity IQ goes beyond correcting loudness characteristics. Onkyo’s sound quality engineers adjust the frequency response to provide the most emotional sound possible, regardless of the music genre. Select your source, tweak settings to your liking – which may vary depending on the speakers you listen through, the type of audio being played, the genre of music, etc. – and customize the experience accordingly.

Powering The Music That Moves You

The M-80 uses a three-stage Inverted Darlington Amplifier. The three-stage Inverted Darlington Amplifier has a very low output impedance and drives speakers powerfully with a large current. Also, by keeping NFB (Negative Feedback) low, it is not affected by noise from the speaker. It offers a powerful yet highly resolving and informative sound. The M-80’s output stage transistors are in parallel configuration, which provides excellent instantaneous current supply capability, further enhancing the rise of sound and the sense of power. The driver stage of the M-80 amplifier uses DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry). Reducing beats generated signals(noise) in the ultra-high frequency band by DIDRC’s high slew rate designand helps produce the natural sound of an analog record.

 


Cutting Edge Compomentry for Captivating Playback
The M-80 housing consists of two aluminum side panels and a steel top panel. The three-piece construction of the housings increases rigidity and improves seismic resistance. Various vibrations are suppressed and sound quality is improved.

 

Create Your Perfect System

The M-80 has an output power of 130w(FTC, 8Ω, 20Hz - 20kHz, THD 1%, 2ch driven) / 200w(4Ω, 1kHz, THD 0.7%, 2ch driven) which allows it to powerfully drive large speakers and bring you dynamic acoustic information. For example, Klipsch Forte speakers paired with the P-80 and M-80 would maximize the dynamic and extended sound of the Forte.

 

From Onkyo Academy: The Benefits Of A Power Amplifier

A power amplifier receives the signal from your pre-amp and literally powers it into your speakers. Think of your pre-amp as a brain, and your power amplifier as the muscle. Separating your amplifiers into pre- and power gives you ultimate flexibility in audio playback. Since they are not affected by each other’s circuits, they can provide high-resolution sound quality through even cleaner signal transmission. Audiophiles are well-known to prefer specific power amps and the way they impact sound quality and coloration. The M-80 is a power amplifier that reproduces the full range of artists or players’ intentions in their music and drives you into a world of emotion.
