Sony TA-F5A amplifier

Integrated Stereo Amplifier

The Sony TA-F5A integrated amplifier is designed for listeners who appreciate excellent sound. And an unusual degree of operating convenience.

Preamplifier/Control Section

The F5A incorporates a newly-designed phono EQ amplifier for low-noise, wide-dynamic-range reproduction. The direct coupled amp, together with an FET/DC negative-feedback circuit, maintains high operating stability. In addition, special capacitors, made of polypropylene film, are employed in the NF-network to ensure ultra-low distortion with voltage increase. Overall results include RIAA equalization accuracy within ±0,2 dB.

An equivalent level of accuracy is provided by the F5A's sophisticated features. Which include a four-gang stepped-attenuator volume control - with 41 detent steps - for accurate level adjustment, with no tracking error between channels. Negative-feedback, stepped-attenuator bass and treble controls are provided for precise frequency contouring; with mid-point "defeat" positions that allow absolutely flat response. There's also a high filter plus a sub-sonic filter that cuts low-frequency components below 15 Hz.

Connections for tuner, turntable, auxiliary source and two tape decks allow truly versatile system functioning. And tape monitor/dubbing facilities let you listen to all program sources during the dubbing process.

 

Power Amplifier Section

The direct-coupled DC power amplifier section utilizes a new monolithic IC for its dual-FET input stage. This is followed by a Class B driver stage and single-ended push-pull final stage. In itself, this amplifier design yields wide-band response, low distortion, high phase linearity and excellent transient response. But performance is improved even further through the Sony PPS system.

 

Pulse Power Supply - PPS

The advanced new PPS system reduces voltage fluctuations to 7% or less, vs the 15% of conventional amplifiers. And this means minimal stereo channel interaction through the power-supply circuit. Instead of going directly through a transformer and then on to rectifiers, with PPS, the incoming AC 120 V, 60 Hz line current is first rectified. The rectified current then drives a DC-to-DC converter, which operates at 20 kHz, instead of he usually 60 Hz. The 20 kHz frequency means the PPS transformer can be small efficient, since the high frequency requires fewer transformer windings. This in turn, means less DC resistance within the windings. With less resistance, there's less voltage drop with increasing power demands. Which results in better power performance - especially with low-frequency transients. And since the PPS never handles 60 Hz line frequency, hum is virtually eliminated.

 

For accurate power monitoring, the F5A features two large meters, which indicate output levels in watts per channel - from 0,01 to 100 watts. Other advanced amplifier features include large, cast aluminum heat sinks for cool operation, plus comprehensive amplifier/speaker protection circuits.

Sony TA-F444ES amplifier

ES-Series Integrated Amplifier

Specially designed for the demands of digital audio

 

Digital audio places stringent demands on the rest of a stereo system. That's why Sony created the TA-F444ES - it matches digital audio's impressive performance, in terms of dynamic range, stereo separation, and low noise and distortion. Many features contribute to this superior performance. Audio Current Transfer (ACT) uses current amplification to reduce crosstalk and improve separation. High dynamic headroom improves dynamic range. Sony's Legato Linear design eliminates switching and crossover distortion. A Linear Gain volume control assures identical performance at all listening levels. These features all contribute to the amp's outstanding performance with digital sources.

 

The best way to demonstrate the terrific performance of the TA-F444ES is to put it through a workout with a Sony CD player. Choose a Compact Disc that features wide dynamic range and low noise. Play the amp very loud first. Let the customer experience the dynamics - be sure he hears both very loud and very soft passages. During a quiet passage, point out the lack of noise. Then turn the volume down to a quieter level. Explain how the performance remains outstanding; i.e. separation, noise and dynamic characteristics are all still superb. Let the customer enjoy the "feel" of the amplifier, and experience its performance on his own.

Sony TA-AX44 amplifier

Remote Control Amplifier

 

Sony products are inspired predictions of the future of technology. We are renowned throughout the world as the major innovator in home electronics. With our TA-AX44 amplifier, we're proud to introduce the audio technology of tomorrow.

These two products (TA-AX44 and ST-JX44) are the electronics of revolutionary audio system for the 80's, and beyond. Forget all your preconceived notion. If you're looking for an integrated amplifier, you should re-consider. If you're already picked out an amplifier and tuner, think again. Even if you're planning to buy a receiver, don't make any purchase yet - our new amplifier and tuner together fall roughly into the same price range as many equivalently-powered receivers. No matter what you had in mind, you owe it to yourself to examine the Sony TA-AX44  first.

First you'll notice the modern, futuristic appearance. The AX44 really doesn't resemble an amp at all, in the traditional sense; there are no knobs, no toggle switches, no power meter. In fact, neither product has knobs of any kind, and both are streamlined and compact. High Fidelity magazine, calling Sony's amp approach "both lean and radical", believes that our new amplifier design indicates "which way you should look if you want a glimpse of the future". This is true of the performance as well as the striking design of both of these products.

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.
