NEC CD-803 cd player

NEC CD-803 Compact Disc Digital Audio Player

The CD-803 is no ordinary CD player, or it is based on NEC's many years of experience in all major areas of electronics and communications engineering - digital, optical, semiconductor laser, electronics, communications and precision machinery. No other CD player manufacturer has the technological background of NEC, the reason why the CD-803 provides unusually good sound quality and reproduction accuracy. Serious audiophiles and audio critics are now discovering what we already know; the CD-803 is the best executed CD player on the market.

What is a Compact Disc Digital Audio System.

Compact Disc Digital Audio is a system whereby an original analog signal is converted into a digital signal - a series of 0's and 1's in the binary code. This information, stored in the form of microscopic pits on a flat disc, is retrived by an optical (laser) beam, and finally converted back into analog form by a digital-to-analog (D/A) converter. The piece of audio equipment that retrives digital information from a CD and converts it into an analog audio signal is a CD player. The CD system offers tremendous advantages over the conventional analog system. For instance, dynamic range and s/n ratio both exceed 90 dB, and channel separation is better than 70 dB across an audio band extending from 5 Hz to 20 kHz. No wonder audiophiles and serious music lovers throughout the world have been awestruck by this new source of ultimate fidelity music.

Ease of operation

The CD-803 enhances ease of operation every bit as much as it improves sound quality. Advanced computer control means that it takes only minutes to learn every operating feature. Simply insert a disc into the front-panel door and touch the Open/Close button. As the door quietly closes, the disc rotates for a few seconds to enter encoded program data into the memory, and then stops. Now, by just touching the feather-touch operating buttons, you are ready to enter the realm of digital sound.

Memory play of up to 99 selections.

Up to 99 selections (tracks) on a disc can be programmed for play in any order. Moreover, by pushing the Repeat button, you can replay programmed selections as many times as you want. The average time it takes to locate  a selection, or access track time, is only three seconds. For your convenience, when you've completed initial programming, you can confirm each programmed selection (its track number and order) on the display by just touching the Memo List button.

Digital-domain technology

A Compact Disc contains a sophisticated error correction signal. By extrapolation, it is possible to reconstruct the original digital pulses accurately in instances where some are unreadable. However, severe dropouts, caused by external noise or damage to the disc, may prove too much for the error correction system. This led NEC to develop a three-stage servo for the disc motor which accurately detects and corrects for dropouts. Faithful reproduction is assured.

Digital-analog interface technology

Digital signals are composites of both left and right channel information in alternating sequence. A switching circuit divides the composite signal  into its left channel and right channel components. For this purpose, NEC developed an electronic switch which allows high-speed switching at a rate 10 times faster than commonly used C-MOS devices or analog switches. This significantly lowers high-frequency distortion. With the NEC electronic switching system, the signal runs in parallel with the Circuit rather than in series (as is the case with other switches(, so signal integrity is maintained.

Analog-domain technology

Once digital signals are converted into analog by the D/A converter, the sampling frequency (44,1 kHz) and its harmonic components must be eliminated completely by a low-pass filter. Commonly used active and passive filters suffer phase-related distortion called group delay, which led NEC to develop the ND (Non-Delay) filter. It reduces group delay at 20 kHz to 1/25 the value of other filter designs and significantly reduces unwanted spurious-frequency response.

McLaren 602 preamplifier

McLaren 602 Control Preamplifier

The McLaren 02 component series represents a unique synthesis of art, science and technology - the realisation of a design philosophy dedicated simply to the accurate reproduction of music.

Form, function and performance specifications all express and testify to this basic ideal. But most important is the innate ability of the range to recreate a true musical experience.

The McLaren 602 is a high gain, high resolution "straight line" preamplifier, fully compatible with a wide range of signal sources from low output moving coil cartridges to high output CD players.

Phono gain can be switched for either moving or fixed coil cartridges. Provision is made for optimum cartridge loading. An input buffer precedes the two-stage passive/active RIAA equalisation where particular care and attention has been given to achieving both amplitude and phase accuracy, not only in absolute terms, but to ensure precise matching between channels.

Power supply design also makes a major contribution to performance. Individual stages of each channel have their own locally regulated supplies fed from a central regulated supply incorporating a heavy duty shielded toroidal transformer.

As a result the 602 possesses superlative dynamic and imaging qualities - clearly focused detail revealing the most subtle instrumental and vocal timbres, with a true perception of image depth and height.

The high undistorted output voltage capability of the line stage with an unusually low output impedance, ensures that the 602 will fully drive any power amplifier even via extreme lengths of shielded cable.

Construction is to the highest engineering standards. The case is entirely non-ferrous - faceplate and side blocks are cut and machined from proprietory extruded sections, top and bottom covers coated with an attractive and durable textured finish.

Front fixing screws, nameplate and all input and output sockets on the rear panel are 24-karat gold plated. Control knobs are turned from solid aluminium, satin anodised to harmonise with the front panel.

Internal construction features gain selected semiconductors and highest quality passive components.

Features:

Phono gain adjustable for MC or MM

User-selectable phono loading

Two-stage RIAA equalisation - passive high frequency followed by active low frequency equalisation

Output muting relay to avoid on/off switching transients.

Heavy duty toroidal power transformer.

Spectro Acoustics 101B preamplifier

Spectro Acoustics Model 101B

Preamplifier/Equalizer

The quality of a stereo component system lies in the audiophil's choice of equipment. The major influence affecting that quality is the interaction and influence of each component on other components and the culmination of those influences on the human ear. This is where the choice is made in selecting "quality" and whether to accept a particular sound as "right"

All things considered, the perfect listening environment is still the concert hall and reproduction of music must remain subjective. However, we want control over what we hear and have the facility to change what it is that reaches our ears. In musical reproduction this function is relegated to the concepts of tonal compensation, balance and volume. The equipment corollary is the modern preamplifier; a device which offers control over the amount of sound reaching our ears and which particular source we will listen to, (whether it be a tape recording, a phonograph record or a radio broadcast). In most cases, there is the ability to change the tonal content at specifically designated frequencies.

Spectro Acoustics, in attempting to obtain maximum performance value, offers the Model 101B preamplifier/equalizer for audiophiles who want the most in flexibility and performance at a reasonable price.

The Spectro Acoustic Model 101B  in order to optimize reliability and serviceability, is designed and constructed to utilize plug-together glass-epoxy circuit boards and 100% monolithic IC circuitry for consistent performance. All controls and connections are human engineered to give simple straight forward operation. The graphic panel of the 101B is a display of exactly what's going on inside of the unit. Control is at the user's finger tips to seek the level and range of sound that achieves personal satisfaction.

The equalizer circuit for the Model 101B is a totally new type based on Spectro Acoustics gyrator synthesis techniques similar to those used in the Model 210 Graphic Equalizer. The design is a hybrid coil/gyrator type which totally eliminates distortion and hum for equalizer circuitry. The filter parameters are optimized for maximum flexibility from a five band design and as an added benefit the highest and lowest frequency bands are "shelving" type to control the response well beyond are "shelving" type to control the response well beyond the extremes of audibility. The usefulness of the equalizer circuitry is further enhanced through its complete availability to line or tape outputs, or total bypass for equalization in/out comparisons.

In phono stage, the Model 101B utilizes an isolated feedback servo op-amp phono stage with ultra-accurate adherence to the RIAA curve. This circuit provides for accurate cartridge response, increased definition of high frequencies and greater dynamic range. Internally accessible cartridge loading components can be adjusted by any qualified and authorized technician to perfectly match the cartridge load for any cartridge.

Description

The Electro-Voice Sentry 100EL powered monitor speaker system combines the advantages of the Sentry 100A monitor with a self-contained, high-Performance power amplifier. It is designed with the broadcast/recording studio engineer in mind, although it is well suited for a wide variety of professional applications. The Sentry 100EL offers uniform frequency response and dispersion across a wide range.

A Super-Dome tweeter is employed to faith-fully reproduce program material at high levels, with response out to 18,000 Hz and uniform dispersion (120(O) at 5,000 Hz) The low-frequency section is an 8-inch direct radiator woofer installed in an optimally vented enclosure with fourth-order Butterworth tuning. The optimally vented design is responsible for the unusual combination of small size, extended bass response and high efficiency. Such performance is simply not available in other enclosures of similar size.

The Sentry 100EL is housed in a utility cabinet wrapped in a special scratch-resistant, matte black vinyl. The cabinet size is intentionally designed fro rack mounting. The steel-reinforced grille is covered with a custom gray cloth. This provides maximum protection and a pleasing, aesthetic quality.

The Sentry 100EL may be driven room any line-level signal source. An XLR-type connector is provided for use with balanced sources, while a 1/4-inch phone jack accommodates unbalanced lines. Uses only the appropriate connector; both should not be connected at the same time. Although both inputs are protected against voltage peaks of up to 100 volts, connection from an external power amplifier is redundant and invariably results in increased noise and distortion.

Most importantly, a sharp cutoff, high-pass filter is included which has been precisely tailored to the Sentry 100EL response. It provides a dramatic reduction of energy-wasting, sub-sonic signals in the amplifier and woofer. By controlling low-frequency cone excursion and amplifier power, program material any often be reproduced at higher levels without distortion and without any reduction in acoustic low-frequency response.

A system level control is located on the front of the enclosure which varies the gain of the amplifier from zero over a useful range of more than 30 dB. Additionally, a red indicator lamp shows when AC power is applied to the Sentry 100EL. A replaceable AC power fuse is located on the rear panel of the system. The rating and type are identified beside the fuse holder. Under normal conditions, even with momentary overloads, the fuse will not blow.

Kyocera D801 cassette deck

Kyocera Model D-801 Cassette Deck Incorporating Dual Capstan 3-motor tape Transport mechanism with Dolby B and C Noise Reduction

With the perfectionist in Mind Cybernet technology has gone all out to produce a cassette deck that will make even the most particular tape enthuiast stop and wonder.

In a nutshell, Cybernet's D-801 has been designed to improve dynamic characteristics. Briefly, although values of static characteristics of a cassette deck (such as signal-to-noise ratio, Wow and Flutter) have almost reached the measurable limit, those characteristics which may not be reflected on actual spec values but which affect audible sound differences must be improved. For this reason, we have decided to use the double capstan two head concept which contributes to meaningful areas of operation, such as Wow and Flutter, frequency response and appropriate head to tape pressure.

FET Amplifier

Because no cassette deck is better than its amplifier, Cybernet uses FET amps in the input stages for superb record / playback head characteristics. Signal-to-Noise-Ratio  and excellent Frequency Response  are improved by direct coupling of the R/P head amp FET to the first stage amp FET.

The Drive for Excellence

To insure constant speed drive and least possible Wow & Flutter, the D-801 uses a 2-capstan drive. This provides individual capstans and pinch-rollers for both the take-up and feed reels, thus insuring the proper tape also runs smoothly and with optimum tape tension, virtually eliminating external shock modulating noise which sometimes causes tape vibration while in play or record mode.

The capstans are driven directly by a brushless frequency generated servo motor. because of this motor driving only the capstans, better and uniform torque is achieved resulting in improved Wow & Flutter and tape speed accuracy.

A second DC governorless motor is used to drive both the take-up and feed reels, while a similar third motor gently positions the record/playback head against the tape surface. This innovative approach results in long lasting head-to-tape positioning accuracy and maximizes proper head azimuth alignment.

The tape transport incorporates two electromagnetic brakes, one for feed and the other for take-up reel rewind. This super braking action protects the tape from stress damage, breaksge or distortion when stopping in the fast forward or rewind mode.

Dolby B and C Noise Reduction

While many audiophiles have been using the Dolby B system, Cybernet now has incorporated a Dolby C system for greater dynamic range and frequency response.

Now, with Cybernet's Kyocera Model D-801 Cassette Deck, new superior recordings can be made.

Basically, the Dolby B system reaches greatest effectiveness above 4 kHz, reducing noise by about 10 dB. Dolby C reaches effectiveness from 1 kHz and above and provides up to 20 dB of NR. By having both systems built into the Model D-801 Deck, Cybernet lets the user make the choice.

APMR Feature

Automatic Program Mute Recording is a system built into the D-801 providing 5-second unrecorded portions in the tape when in record mode. In playback these gaps are useful for locating the beginning or the end of the recorded segments. The 5-second unrecorded gaps are utilized by the auto search feature to stop at the beginning of the program continues for five seconds and automatically advances to the next program unless the play button is activated in order to stop auto search.

Versatility and Convenience

In addition to its feather-touch pushbutton mechanism, automatic memory functions are included for memory stop, auto stop, auto play and auto repeat. Other functions included are shutoff at end of playback, record, fast forward and rewind modes. Complementing these features is an electronic 4-digit counter for elapsed time, remaining time and stopwatch.

Tape selection, bias and equalization are provided for all current tape types including metal. In addition, fine adjustment provides optimum performance from the selected tape brand.

Performance is assured by Cybernet's use of a Sendust alloy rewind/playback head. This meets the needed demand for top=notch performance with to-day's metal tape. A built-in 400 Hz calibration tone enables proper adjustment of record/playback levels for each channel.

Other convenience features include LED indicators for function modes, L/R channel peak levels, record level balance and output controls, illuminated cassette compartment with viscous damped cassette door and headphone jacks for private listening, as well as record peak level hold.

Tannoy DC200 loudspeakers

Tannoy DC200

The Tannoy Dual Concentric principle is widely accepted as one of the major technological breakthroughs in the design of loudspeakers.

The Dual Concentric is, in fact, "2-speaker-in one". If you took the grille off any Tannoy Dual Concentric there is what appears to be a single drive unit. Closer examination will show the compression high frequency driver sharing the same chassis as the bass unit. These two separate drive units provide a single xis for the reproduction of sound at all frequencies. The audio signal is supplied to each drive unit by a time compensated crossover, that aligns both high and low frequency sound sources towards a single point on that axis.

The music is clearer and more natural because the real harmonics and dynamics of the instruments and voices are retained, while the stereo image of the original performance is sharper and more convincing.

Tannoy's strong reputation for transducer design within the broadcast and recording industry has been harnessed within the recently designed 10" Dual Concentric used in the DC200.

Both DC's have excellent frequency response and good dispersion, and their ability to reproduce wide dynamics makes them particularly suitable to be used with the latest CD systems.

With the new DC series, the hi-fi enthusiast can experience all the characteristics and benefits of a major studio monitor in a smaller, cleanly styled enclosure.

McIntosh MC1201 power amplifier

McIntosh MC1201 Monoblock Power Amplifier

producing a massive 1200 watts, the MC1201 is the most powerful amplifier ever created by McIntosh Laboratory. The extraordinary quad-differential design of the MC1201 actually consists of two complete amplifier circuits, one the mirror image of the other, whose outputs are combined in the unique McIntosh Output Autoformer, resulting in totally balanced operation from input to speaker output and the cancellation of virtually all distortion.

The McIntosh Autoformer, a hand-crafted transformer with output connection for two, four and eight ohms, creates an ideal impedance match to quard against distortion and reduction in power. A McIntosh amplifier with an Autoformer can also safely drive multiple speakers connected in parallel, without shortening the life expectancy of the output stage. Far from exacting any performance penalty, the Autoformer's frequency response exceeds that of the output circuit, and extends well beyond the audible range, for almost immeasurably low distortion.

Exclusive McIntosh Power Assurance System - A collection of technologies that enhance performance and reliability and protect the amp and the loudspeakers

Power Guard Clipping protection - A waveform comparison circuit continuously monitors both input and output signals and dynamically adjusts the input level to insure maximum output power while preventing harsh sounding clipping distortion.

Sentry Monitor current protection - continually senses the voltage and current of the output stage and confines it to a safe limit, without limiting power output.

Thermal cutouts - protect your amp from overheating if cooling air is blocked and transistors become too hot.

DC failure protection - guards speakers against output circuit failure. The output autoformer prevents DC from reaching the speaker.

Turn-on delay - delays operation for about two seconds after turn-on, to silence any pops or thumps generated by other equipment.

Soft Start inrush protection - eliminates component stress during turn-on. Thermistors in the power transformer act as a cushion against inrush current. Soft Start is one of many details that contribute to the remarkable longevity of McIntosh equipment.
