Pioneer CS-66G loudspeakers

40-watt, 10-inch 3-way speaker system for low-distortion natural sound reproduction

Balanced sound reproduction from  a compact, highly-versatile speaker system is now yours with the Pioneer CS-66G. This smooth, clear-voiced system features three cone type speaker units in a three-way design. Its 10-inch (25 cm) woofer, 6,5-inch (16 cm) midrange and 3-inch (7,7 cm) tweeter reproduce the entire sound spectrum with natural fidelity. Low-distortion/rich performance is assured from any power input up to a maximum of 40 watts , thanks to its high efficiency and sensitivity. This multi-purpose sound system is perfect for use in the average-sized home or office setting for stereo or 4-channel. Its handsome enclosure with walnut grain finish is fitted with a removable, carved wooden grille. Thanks to its compact size, the CS-66G can be placed horizontally or vertically in bookshelf or cabinet-top locations to provide maximum sound dispersion.

 

10-ibch Woofer

A wide range of musical program sources, including those with heavy bass sounds, are handled with ease by the 10-inch woofer in the CS-66G. The so-called "clipping" of low-frequency sound is suppressed to reduce distortion and enhance richness. Since this woofer is especially designed to respond faithfully to signals as low as 35 Hz, it ranks among units in the 12-inch and larger class. It features a large power input capacity and delivers excellent transient response.

6,5-inch Midrange

The brilliance of brass and precision instruments, the richness of the human voice and the all-important middle frequency sound of a full orchestra come through with natural clarity and realism, thanks to the midrange speaker unit in the CS-66G. The back of the midrange is sealed tight to prevent interference with the other two speaker units.

3-inch Tweeter

Distinguished by its fidelity and linear high frequency response characteristics, the 3-inch tweeter in the CS-66G adds a clean, crisp feeling to all music. The overall sound of the CS-66G is further brightened by the exceptionally smooth transient response of this essential unit.

 

Crossover Network

As in all-multi-way speaker systems, the crossover network in the CS-66G goes a long way in determining overall quality. Pioneer has employed selected quality parts, including a large ferrite core, to create a special crossover network to handle the full audio spectrum with a minimum of distortion and damping loss.

Walnut-Grain-Finished Enclosure

The easily-removable, carved wooden grille of the CS-66G permits instant inspection of the interior of this advanced high-fidelity speaker system. The oiled walnut-grain side and end panels of the sturdy enclosure harmonize with any decor.

Pioneer PL-117D turntable

Full-Automatic Turntable with Precision 4-Pole Synchronous Motor

The PL-117D from Pioneer offers the important combination of quiet, stable turntable rotation and convenient full-automatic or manual operation. As quiet a performer as your're likely to find in a moderately-priced turntable, the PL-117D owes much of its outstanding operation features to the use of a high-torque 4-pole synchronous motor and to its howling-free, hand-crafted cabinet. These important design features, coupled with a sensitive S-shaped pipe-arm with anti-skating device, ensure that the PL-117D will deliver the finest of performance specifications - wow and flutter of only 0,07% (WRMS) and a very high Signal-to-Noise Ratio of 63 dB (DIN B). Beautifully constructed, the PL-117D is a perfect addition to a new system of stereo components that is designed on the basis of tonal quality.

 

Belt-Drive system with 4-pole synchronous motor

The strong turntable platter, free from fluctuation in line voltage and load, is rotated by a high-torque precision 4-pole synchronous motor and its polished polyurethane belt. These turntable features contribute to wow and flutter of 0,07% (WRMS) and high Signal-to-Noise Ratio of 63 dB (DIN B)

 

Sensitive S-shaped pipe-arm with anti-skating device

An angular-contact bearing is employed at the revolving point of the tonearm's ball-bearing which ensures that the precision tonearm and its easy-to-operate anti-skating device can trace record grooves faithfully during playback, either vertically or horizontally, with even light stylus pressure cartridges. The turntable is also complete with a direct-readout stylus pressure counterweight for easy replacement of cartridges.

 

Convenient cueing device

The viscous-damped cueing device is connected to the arm elevation lever to help prevent damage to both stylus and records often caused by misoperation.

 

Howling-free, Double floating system for superior tonal quality.

The cabinet of the PL-117D is strong, howling-free and typical of quality Pioneer craftsmanship. Its solid surface panel features such excellent properties as optimum inner loss, impregnable strength and high density. It is thus free from resonance. The turntable platter and tonearm are fixed to the  chassis of the PL-117D, suspended from the surface panel with springs. The motor is fixed to the surface panel with a rubber cushion. Further improvements that contribute to outstanding tonal quality and exact record reproduction are the insulators composed of butyl rubber and natural rubber which prevent vibration conveyed from the floors. The cabinet itself is elegantly styled in an attractive walnut grain finish.

Pioneer QX-8000A 4-channel receiver

To compose an ideal 4-channel stereo system, the QX-8000A, a solid state AM/FM stereo receiver, can be combined with four speaker systems, tape decks, turntables, etc. With a 4-channel stereo tape deck or cartridge tape player installed, the QX-8000A can provide a discrete 4-channel playback of programs recorded on tape.

 

4-Channel Reproduction from Matrix 4-Channel Source

The self-contained matrix circuit permits 4-channel reproduction from matrix 4-channel records or FM stereo broadcasts. The mode switch has positions for regular matrix and SQ matrix reproduction, allowing reproduction to take either of these forms.

 

Matrix Reproduction from 2-Channel Source

A 2-channel signal from a record of FM broadcast can be reproduced in 4-channel form via the regular or SQ matrix circuit. In this case, the result is an improvement over ordinary 2-channel stereo reproduction.

 

2-Channel Stereo Performance

Conventional 2-channel stereo performance can be provided through an arrangement or two speaker systems in the front; Ieft-side speaker system and right-side speaker system. A 2-way multi-amplifier system can be set up by installing an electronic crossover network.

 

Features

 

Acoustical field reproduction from 4-channel stereo

The amplifier section consists of four separate channels having excellent frequency response and very low distortion, providing for 4-channel discrete reproduction of a 4- channel source (recorded tape).

 Choice of matrix decoder

The OX-8000A offers a choice of two decoders; the regular matrix and the SO matrix. The source may be a matrix recording or FM broadcast of a matrix recording. The result is realistic 4-channel reproduction.

 Matrix circuit for ordinary 2-channel stereo

Use of the internal matrix circuit enhances the effect of ordinary 2-channel stereo source material, over and above that normally obtainable.

 Also works as standard 2-channel stereo receiver

lf you only have one pair of speakers now, you can use the OX-8000A as a regular 2-channel stereo receiver and add the other two speakers at a later date.

 Permits 4-Channel or 2-Channel tape recording

lf you already own a 2-channel stereo tape deck, you can go on using it for recording and playback as before. However, if you plan to buy a 4-channel tape recorder, you can use fully the discrete 4-channel capabilities, playing back 4-channel pre-recorded tapes with true 4-channel sound.

 Fully equipped with 4-channel Auxiliary controls and inputs

There are three balance controls: front left-right balance, rear left-right balance, and front-rear balance. These give you complete control over the 4-channel sound field. Also, separate stereo headphones for the front and rear channels are provided important when monitoring 4- channel tape recordings. Other features include "speakers in operation" indicator lamps, program indicator lamps, loudness switch, high and low filter switches, FM muting switch, 300Q and 75O (coaxial) FM antenna terminals, and a 4-position channel mode selector.

 Versatile tape-to-tape duplicating facilities

Normal 2-channel tape-to-tape dubbing is possible too, as well as 4-channel tape-to-tape duplicating.

 FET-equipped FM tuner

The FM tuner is equipped with an FET in its front end to improve selectivity and sensitivity. Also, the lF stage employs one hybrid and one monolithic lC, replacing numerous transistors, ceramic filters, etc., and raising the tuner's sensitivity and selectivity. The FM MPX decoder works according to the time switching system and boasts excellent channel separation. Tuning is made easy by the linear FM dial and the double (signal strength and center zero tuning meters.

 Built-in AM ferrite Bar antenna

Sensitive and highly directional. An outdoor AM antenna is not required in most cases.

 Low-distortion High-Power Audio amplifier

Both tone controls and equalization amplifier operate with a generous amount of negative feedback for improved frequency response accuracy and flatness. The power amplifier is a quasi-complementary design, a tried-and-true circuit construction.

 All new 4-Channel exterior design

Cabinet and control panels are visual symbolizations of the Pioneer "4-channel" concept, with a recessed, framed, square tuning dial, a modernistic and logically arranged control panel, and the famous silver-black-wood Pioneer color styling.

Pioneer PL-540 turntable

 

Auto-Return Quartz-PLL DC Direct-Drive Turntable

Now that you know to look for in a turntable, look at the PL-540 from Pioneer. If you've ever owned a good manual single-play turntable without automatic return, you know how desirable the latter can be - if only it doesn't compromise tone arm sensitivity.

The auto-return system in the Pl-540 doesn't harm sensitivity. If you've ever wished your turntable had the accuracy of a professional studio type - but without a studio-standard high price. The DC Hall motor and Quartz -PLL in the PL-540 deliver the same accuracy - 0,025% or less wow and fluter - as monitor turntables used in record-cutting studios. But its price is considerably less. If you've suspected that the boxy cabinet and shaky little feel on yesterday's best turntable are not  enough to be called "best" today, and if the latest improvements in tone arm suspension and platter design have set you thinking about replacing your favorite noisy old faithful; look at the Pioneer Pl-540.  And as you do, remember to ask for an audition of its superb tonal quality. Your ears will see that it's the turntable you've been listening for.

 

Our Own Quartz-PLL Servosystem

There are 200 evenly-spaced magnetic "bits" on the bottom of the rotor of the DC motor, and each has two poles; the north pole of one is opposite the south pole of the next, and so on. Then positioned below is a circular circuit board on which is a printed coil with 200 poles. A current proportional to the actual speed of the direct-drive motor is generated in the coil circuit as the magnets rotate above, and that current is sent to the PLL or Phase-Locked Loop circuit and Sampling & Hold Circuit in the servo. There phase is compared with that of an ultra-accurate reference signal from the built-in Quartz oscillator. Differences in phase if any, are converted into control voltages which in turn "tell" the motor to speed up  or slow down to achieve absolutely accurate rotational accuracy in far less time than it takes your eye or ear even to begin to detect even the slightest error.
