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.

Drive System Technology

The Sony Linear Torque BSL motor for smooth, precise rotation

Most direct-drive motors generate their power with an array of electromagnets mounted in a circle within a rotor ring. As the rotor turns, the torque increases and decreases as a result of the spaces  - "slots" - between the electromagnets. The wavering-force effect is called "cogging". Sony has eliminated cogging with the remarkable BSL motor. There are no brushes, no slots, and the magnetic force is constant. Cogging is impossible, and the torque delivered to the platter is uniform, smooth, and even. As a further benefit, the Sony brushless design makes the BSL motor unusually quiet, durable and trouble-free.

 


Magnetic servo control for superior accuracy.

Because household voltage itself is not without fluctuations, no direct-drive motor can be depended on - by itself - to maintain absolutely constant speed. Most good direct-drive turntables, therefore, have introduced servo electronics, which monitor the speed at which the motor turns and adjust the electrical input to correct for deviations.

Most servo systems depend on a generator, mounted within or below the motor, to monitor motor speed and feed that information back to the control circuits. High-quality turntables use pulse frequency generators for improved accuracy. These Sony turntables are better still. They offer markedly increased accuracy. These Sony turntables are better still. They offer markedly increased accuracy with the Magnedisc system, which monitors the turning speed, not at the motor, but at the outer rim of the platter where there is room for many more pulses. Based on Sony-developed technology for computer-controlled precision machinery, this system uses a magnetic pickup head to read the 512 pulses imprinted on the platter's outer rim. The information is relayed to the servo control so rapidly and precisely that any speed variation is corrected before it can affect the musical signal.

Onkyo DX-7500 cd player

Onkyo DX-7500 is a fully featured Compact Disc player. It features dual 18-bit D/A converters with eight-times oversampling at 352,8 kHz. The player also makes extensive use of optical signal transmission and isolation techniques.

Onkyo's Opto-Drive system is claimed to completely eliminate any electromagnetic interference from the outputs of D/A converters by using phototransitors instead of diodes to regulate the power-supply voltage to the converts. Optical coupling between the digital and analog circuitry of the DX-7500 eliminates the possibility that digital signals could leak into the analog sections and degrade the output quality. The analog audio outputs are supplemented by two digital outputs - electrical and optical - for use with an external D/A converter.

In addition to its internal sophistication , the DX-7500 offers almost every feature one could hope to find in a CD player. Besides the usual operating functions, including repeat of a track, disc, or any selected portion , it has a Time Editing feature that determines how many tracks can be accommodated on each side of a tape cassette.

The memory system can be programmed to play up to twenty tracks of a CD in any order, and a Memory Edit feature allows the program to be modified at any time. The player haas a shuffle-play mode, in which all the tracks on a disc are played back in a random order. It also provided direct keypad access to any numbered track.

Onkyo T-4055 tuner


 AM /FM Stereo Tuner

Front End

A tuner that catches distant signals along with a lot of noise is almost usless. What is needed is a tuner that catches the signal, detects it and at the same time rejects interference and noise as it recomposes the signal into a fresh sound image. This objective is accomplished in the front end of model T-4055. dual gate MOS FET's are used in the RF and Mixer stages. This design makes the tuner sensitive to weak signals. Since it is able to handle both types of signals model T-4055 can bring a true music image from distant as well as near FM stations. This unit has a spurious noise rejection figure of over 90 dB

 

IF Stages

IF stages play an important part in tuners because they determine the distortion ratio of the whole unit. Model T-4055 is deisgned with 6 IF stages so that distortion can be kept to a minimum. They also provide the needed gain in the tuner. The tuning circuit of model T-4055 employs caramic filters in place of the usual coil and capacitor types. They provide sharp selectivity and broad bandwidth  FM signals are less susceptible to interference but can still be bothered by advers atmospheric conditions and made interference such as ignition noise. In model T-4055, 5 of the 6 IF stages act as limiters to keep out such botheresome interference. This unit has a capture ratio of 1,2 dB and its alternate channel attenuation (selectivity) is better than 80 dB. Model T-4055 takes the worry out of having so many FM stations on the air at the same time. It separates them effectively.

 

Ratio Detector

A ratio detector is needed to convert the FM sugnal into an auio signal. In model T-4055 a very advanced design is used. A look at the ratio detector S curve shows that this tuner provides a very broad bandwidth of 900 kHz, peak to peak, along with perfect linearity. The ratio detector operates in combination with the front end and finely designed IF stages for excellent reception with a minimum of distortion. Model T-4055 keeps distortion to less than 0,2% (mono) and 0,5% (stereo)

 

Muting Circuit

Onkyo designed model T-4055 to be very sensitive and this created a new problem. Interstation moise also ended to incerase along with sensitivity. To eliminate this type of interference there is a special muting circuit controled by a muting switch which is turned on the irritating interstation noise can be eliminated. You will receive the station you want without interference from other signals. However, if you want to listen to a very distant and weak station the muting switch should be turned off or the muting circuit will cut out the desired station also.

 

Automatic FM MPX Section

Model T-4055 boasts of an improved FM stereo/mono automatic switching circuit. Most modern tuners, of course, automatically change from stereo to mono and mono to stereo. Model T-4055 is different and better. It not only detects the 19 kHz pilot carrier which activates the stereo circuit but it also measures the strength of this carrier. If the 19 kHz carrier is not strong enough for good FM stereo reception this tuner will not change to stereo. The purpose of this special circuit is to provide good music at all times whether this music is stereo or mono.

AM Section

The AM sectio od model T-4055 was not neglected either. It sounds much better than you would expect AM to sound because of the advanced circuit technology and latest components that are used. A two gang variable capacitor, ceramic fiters, and a sensitive buikt-in ferrite core antenna are a few of the element that make this AM section highly sensitive and selsctive. It's not as good ass FM, of course, but for AM it's very good.

 

Variable/Fixed Output Level

Model T-4055 has one fixed and one variable output jacks in the rear panel. The fixed output is 0,75 V (FM). The variable output can be changed from 0-2 V (FM). There is a level control knob in the front panel for changing the output from 0 - 2 V (FM)

 

Multipath Detection System

Usually an oscilloscope must be used when trying to point the antenna in any direction for best reception of a particular station. Model T-4055 also has an output so that an oscilloscope can be used to find the directtion for optimum reception. But  Model T-4055 also has something alse - a Multipath Detection System. With this model it is possible to hear the multipath sound directly through the right speaker. The operation is simple. Set the lever in the back of the panel to Multipat Detection. Turn the antenna until you hear the least noise coming from the right speaker. That is the position for best reception.
