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.

Sony TC-K5 cassette deck

The front-loading Tone Controls-K5 is Sony's middleweight champion - with heavyweight features and performance that set it apart from other cassette decks in its class. Features and performance that give you maximum value. And the quality that only our specialized recording-equipment background can provide. Many year's experience in tape-deck manufacturing and magnetic tape production - applied to deliver maximum cassette-deck performance, convenience and dependability.

 

Design and Performance

The K5's tape transport system has been designed for excellence in every critical performance area, including Frequency Response, Signal-to-Noise Ratio and Wow and Flutter.

A DC servo-controlled motor, with integral FG (frequency generator) and electronic servo-circuit, is employed for capstan-drive. This advanced design assures the utmost speed accuracy, automatically compensating for any interference which would cause speed irregularities, and smooth, stable tape travel results. the audible result is reflected in a Wow and Flutter level only 0,05% (WRMS). In our special DC servo-controlled motor, a tiny frequency generator, mounted at the bottom of the motor shaft, produces an AC signal whose frequency is proportional to the motor's instantaneous speed. This signal is run through a limiter, or 'WAVE FORM SHAPER", then a "frequency-to-voltage converter" which produces a DC output proportional to the signal fed to it. This output is compared with a highly stable DC reference voltage in a "voltage comparator". And the "difference voltage" from the comparator stage is fed to a DC amplifier which then drives the motor at exactly the correct speed. Unlike conventional servo-controlled motors, the Sony FG servo system maintains constant speed under widely varying temperature conditions. And to assure low noise, the motor is triply shielded with vibration-proof rubber, aluminum and steel. In addition, the motor is free from interference generated by external noise.

C.E.C. CD3300R CD player

State-of-the-art Cl and LEF technologies

Cl(Current Injection) is a landmark technology for shortening the signal path, improving the sound quality and measurement specs significantly. The eftective simplicity of Cl requires a non-feedback-loop amplifier. While Cl replaces the voltage amplifier, LEF guarantees the best performance of the current amplifier with low THD. The both technologies complement each other and overcome the limitations of traditional Op-amps to a better standard of music reproduction. The unique combination of Cl and LEF single-ended class A technologies in only one amplifier per balanced analog output state provides you with today's best possible sound quality. The amplifier section runs without overall negative feedback, and the amplifier creates no dynamic distortions.

 

Advanced D/A conversion

PCM1796 with balanced current output applied in the CD3300R is one of the latest Burr-Brown's DACS compatible with 24bit/192kHz. A multi-bit ladder-type design is ingeniously combined with a Delta-Sigma design to create a new hybrid advanced segment converter with superior dynamic range.

 


Attention to the power supply

A stable power supply is essential for high-quality sound reproduction. A toroidal power transformer provides completely separated power supplies for the CD drive and for the D/A conversion for the best performance. The detachable AC power cord can be changed to suit particular sound tastes.

 

Digital output

In addition to a coaxial and an optical digital outputs, the CD3300R also has an AES/EBU(XLR) digital output, enabling connection to a wide range of digital devices including external D/A converter and digital recording device like CD recorder.

 

Analog output

In addition to the conventional unbalanced RCA analog output, a balanced XLR output is applied for the best performance in CD3300R due to a truly balanced and full difterential signal proceeding.

C.E.C. AMP3300R amplifier

Control/Power Amplifier

Features the Load Effect Free (LEF) circuit

Pure class A single-ended, no-feedback circuit

Volume control with "Intelligent Gain Management" (IGM)

One balanced XLR Input and four unbalanced RCA inputs

 

Pure class A single-ended amplifier

The AMP3300R is a class A amplifier that features an extremely pure single-ended circuit with one voltage amplifier stage and one current amplifier stage that handle all music signal processing. The AMP3300R overcame the inefficient and extremely low output, which earlier class A amplifiers had, by combining the high-quality class A amplification with the Load Effect Free (LEF) circuit that avoids various sources of nonlinearities.

 

CEC's original LEF circuit

The AMP3300Rfeatures CEC's unique Load Effect Free circuit to completely avoid all factors that result in deterioration of sound quality. The LEF circuit makes possible pleasing and detailed playback as well as high efficiency. Every amplifier should be a perfect voltage source in theory while the current into the speaker is likely out of phase in relation to the voltage. The phase relation varies with the frequency, and it is even dynamically moving. NFB amplifiers are sensitive to this matter, specially to the dynamic changes. The LEF's current control stage is not linked to the signal voltage, and just checks the current requirement that depends on the speaker load without "knowing" about the phase relation to the voltage. This "phase independent operation" is an important reason for the obvious drive ability as well as sound quality. The AMP3300R also has an automatic bias adjust function for stable signal processing.

 


Fully balanced signal processing circuit

The AMP3300R adopts a full-balanced circuit design to achieve extremely high-speed and low-distortion signal transmission. Unbalanced input is converted to a balanced signal in the very first stage of the amplifier with no deterioration of sound quality, resulting in a fully balanced output signal. In addition, the left and right signals are processed in circuits divided to two different layers to ensure channel separation and a high-level stereo image.

 

IGM volume control

The Intelligent Gain Management (IGM) system is applied to minimize signal loss during volume adjustment. Sound level is adjusted by controlling the amplifier gain itself with a knob on the front panel. The input signal is not degraded by any mechanical volume resistor or CMOS device. As a result of this, lowest noise, low distortion and highest dynamic performance has been achieved.

 

Input and output

The AMP3300R has four conventional unbalanced RCA inputs and one balanced XLR input that enables a high quality balanced connection with a player like CEC's CD3300R. In addition, the AMP3300R can be connected to a recording devices such as tape recorder.

The speaker output with plastic cover in consideration of safety can be connected with a banana-plug or a Y-shaped plug.

 

Protection function

When continuous clipping is detected, the volume level is reduced automatically. In case of overheating, the unit is completely shut down. After cooling down, it turns on automatically.
