Pioneer SX-D7000 receiver

 Pioneer SX-D7000

Stereo receiver with non-switching DC Power Amp Quartz-PLL tuner and electronic touch tuning

Power Amp Highlights

Protection circuitry has gold-plated dual-contact relays for fast response and unfailing dependability should power-related misshape occur. the receiver and your speakers are fully protected the circuitry mutes power on/off noise, protects power transistors and speaker from abnormal direct-current potentials and overload at the output.

Preamp/Control Highlights

Function Indicators (FM/AM/AUX/PHONO) - Pioneer's "Light Touch" buttons are employed to indicate the selected function. The buttons are lit and glow green when engaged.

Speakers (A, B, C) switches with LED indicators

Low Subsonic Filter is 18 Hz with -6dB/oct. curve.

Tape Monitor and Duplicate switches for decks 1 and 2, deck-to-deck dubbing is easily accomplished between the two in either direction.

Loudness, Balance, Mode (Stereo/Mono) and Muting (-20 dB) controls

Adaptor switch to patch in a signal processor unit such as a  graphic equalizer, dynamic processor or reverberation unit.

Attenuator-Type Master Volume Control

We've improved the "feel" of the master volume control by giving it decibel calibrations from 0 down to -70 dB.

For operating convenience, the control has 41 detents or click stops. The mechanism which actually controls the volume - the potentiometer - is elaborate with four-ganged design. there is one two-ganged potentiometer ahead of the tone controls amp. another behind. the thoroughness of this design is apparent in improved s/n ratio during low-level sound reproduction.

Low-Distortion Tone Control Amp

This is an IC-built circuit block, employing NFB (Negative Feedback) to lower distortion to 0,005% or less (4V output) over the 20 -20,000 Hz range. Bass and treble adjustments are made by the two slider controls - each with 11 click stops - in conjunction with two switches for Turnover.

The Turnover for Bass offers a choice of 400 Hz or 200 Hz as the frequency at which response is down by -3 dB; turnover for Treble gives a choice of 2,5 kHz or 5 kHz. only a tone control this elaborate and far-reaching provides total system control. You may, if you wish, bypass the tone circuit.

Pioneer CT-7R cassette deck

Auto-Reverse Playback/Recording Cassette Deck

The CT-7R records and plays back both sides of a tape, automatically. Now you can record up to 90 minutes of music (with C-90 cassette) without interruption and play it back over and over as long as you like. This may be a rare feature but what's even rarer is that the CT-7R is direct-drive.

As in the more expensive models, the transport in the CT-7R uses three-direct-drive-motor, each a Pioneer brushless Hall type. This contributes to the low wow and flutter of this deck, 0,04% (WRMS) or less.

The recording/playback head is constructed of Pioneer-developed Ribbon Sendust that is three to four times thinner than those used in conventional sendust heads. This explains the extended high frequency response of this deck - to 20,000 Hz. Transient response is superior and bass response is solid. The :Small-Window" Erase Head assures total erasure of previous recordings.

And like the more expensive models, the CT-7R is endowed with a full complement of Computer-Aided Conveniences. It's easy to find the end of recorded program material on a tape, cue in on any desired selection, return to the very beginning of the start of the next selection, hear the same selection over and over again, and skip the blank, programless section at the end of the tape and start play right at the beginning of the first selection of the flip side - without even touching the operating controls.

A 4-bit microcompuer, programmed to order, controls every operation for sure and quick tape transport motion. The three-direct-drive-motor tape transport means operational ease such as fast direct change of modes and flying-start recording.

In addition to standard Dolby-B noise reduction, the CT-7R has Dolby Labs newest circuit, Dolby-C. the Dolby-C provides an additional 10 dB of noise reduction (at 5 kHz) over standard Dolby-B's. that's a total of 20 dB of noise reduction. It also has increased MOL (Maximum Output Level) to assure an extended high end.

The Auto Tape Selector detects coded recesses along the edge of each cassette casing and automatically sets the deck to the proper bias and equalization settings. An 8-LED bar-graph display )one per channel) is accurate and responsive. Other features are; One-Touch Recording, Recording Mute, Timer-assisted record/playback, wired remote control and two-way Memory Stop.

Pioneer CT-6R cassette deck

A full-featured cassette deck

You'll find in the CT-6R all the essential technology of the finest Pioneer decks. Features like the Ribbon Sendust Head, 3-motor direct drive design, C.A.C. (Computer-Aided Convenience), ans so forth. It's priced, however, within the reach of any audiophile.

Just as in our finest decks, you'll find a Pioneer-exclusive head design - the Ribbon Sendust Head - for recording and playback in this model. This laminated head uses a dozen ultra-fine sendust "ribbons" to reduce eddy currents and therefore reduce core loss. This results in extended high-frequency response, all the way to the limits of audiobility. Transient response and treble clarity are improved for better still reproduction quality. During playback this same head is used for either direction of tape travel, assuring matched response regardless of direction. During recording the "Small-Window" Erase Head is also at work wiping old recordings completely clean.

Another design feature found in our more expensive models is the three-direct-drive-motor system. One motor drives the capstan and the other two drive the reels. These brushless Hall motors are largely responsible for the low wow and flutter of this deck - a mere 0,04% (WRMS). This transport design also improves head-to-tape contact for fewer dropouts and variations in recording or playback levels

Hiss and MOL-limited saturation distortion have become problems of the past. New Dolby-C noise reduction has reduced noise by 20 dB at 5 kHz, while improving high-frequency response by expanding the MOL (Maximum Output Level). Now, the usable dynamic range - up to 90 dB - is sufficiently wide to match even digital or direct-cut recordings.

The C.A.C. (Computer-Aided Convenience) features that the CT-6R offers include index Scan, Music Search and Blank Skip and Reverse. And the three-direct-drive-motor tape transport offers quick and direct change of modes and flying-start recording.

Program peaks are shown by a responsive 8-LED bar-graph display (one per channel) Other advanced deck features include the Auto Tape Selector, one-Touch Recording, Recording Mute, a wired remote control and more.

Pioneer SA-5500II amplifier

Popular Power Output Rating with Low Distortion Circuitry in Basically Beautiful Stereo Integrated Amplifier

Pioneer stays ahead in the creation of highly musical high fidelity components for all budgets. The SA-5500II is a popularly-priced stereo integrated amplifier which employs many of the same futuristic advances as found in our more expensive models. Its power output is ideal for small to medium-sized listening rooms; it delivers continuous 15 watts per channel, min. At 8 Ω , from 20 to 20,000 Hz, with no more than 0,5% T.H.D. its main volume control has 41 contact point with click-stop so that you can control the power output with precision. The tone control section employs CR elements to avoid noise and equalization error in Bass and Treble ranges. And other features like the tape monitor, two-system speaker selection and more make it truly useful for the stereo music fan.

 

Tone Control Amplifier with CR Elements

Pioneer's SA-5500II takes advantage of the many futuristic electronic developments featured in our larger and more expensive integrated amplifiers. An example is the precision tone control amplifier circuit. It uses high-grade CR type elements to avoid noise and distortion. The bass and Treble controls can be used to help you compensate for irregular acoustic in your listening room

Professional Feel for main Volume Control

The precision operation of the SA-5500II is evident even in the feel of the master volume control. It has 41 click stops, representing 41 contact  points, so that you can re-adjust the output level exactly when required.

Phono Equalizer Provides Less Distortion

Today's records contain a high degree of dynamic range and therefore must be equalized with precision for top musicality. The phono equalizer in the SA-5500II provides a very precise RIAA equalization so that dynamic range is preserved white noise and distortion are lessened.

Power Output Perfect for Musical Sound

Small to medium sized listening rooms don't always require high-powered amplifiers. In fact,, the 15 watts per channel output, of the SA-5500II is ideal for such rooms when you want top musicality . This power output is never affected by excess distortion or noise, thanks to Pioneer's advanced circuitry.

Pioneer TX-5500II tuner

Truly High Fidelity Performance in Amand FM Stereo in An Advanced IC-Equipped Tuner in Attractive Price Range

Pioneer stays ahead in rich musical performance and interference-free reception when it comes to AM/FM stereo tuners in every price category. The TX-5500II is no exception, despite its attractively low price. The latest Pioneer advances in circuitry as perfected by our research and development teams are employed, often in microcircuit IC forms, to increase sensitivity and selectivity, reduce the Signal-to-Noise and Distortion irregularities, and improve overall tonal quality. An example is the PLL (Phase-Locked Loop) IC used in the FM stereo multiplex demodulator section. Another is the FET and 3-gang variable capacitor construction of the FM front end for more sensitivity. Still another is the use of the ceramic filter-plus-IC from of the FM IF section to provide pinpoint selectivity. All this pays off in better tonal quality, less distortion and more precise station selection in a functional, versatile tuner at a popular price. It's the TX-5500II from Pioneer, a good way to stay ahead in hi-fi.

 

FM Front End is stable but highly sensitive

You won't find better performance for the price. Pioneer boosts FM sensitivity to 10,7 dBf (1,9 µV) IHF. In the TX-5500II by using a low-noise FET and a 3-gang variable capacitor in the stable FM front end. Interference is rejected and the Signal-to-Noise Ratio is improved

Exclusive IF circuit uses ceramic filters and IC

Stability and limiter characteristics are improved while at the same time selectivity and capture ratio are boosted. This results from Pioneer's use of an exclusive high-performance IC and only those ceramic filters which can deliver the best phase linearity in the IF circuit.

Stereo separation is more stable with PLL

Outside influences such as changes in temperature and moisture can never affect the stereo FM multiplex demodulator because we use a Phase-Locked-Loop (PLL) circuit in IC form. The circuit has distinguished Automatic Gain Control (AGC) characteristics and stable detector output, factors which pay off in better stereo FM performance in strong signal areas.

Super-simple tuning system for more accuracy

The clean looks of the Pioneer TX-500II are functional, too. The FM-linear dial scale, a smooth-turning, flywheel balanced tuning mechanism and a combination signal-strength (FM/AM) and center-of-channel (FM only) meter make precision tuning simple.

A valuable investment in versatility

FM muting is automatically provided when you switch to FM Auto. The FM Mono positions lets you select more distant stations. And in the AM position, a high-integration AM circuit goes on line to bring you low-noise AM performance.

Pioneer CT-5 cassette deck

Designed for Easy Operation

The CT-5 is designed for utmost ease of operation and control. Its IC logic-controlled tape transport provides touch operation and direct change of modes. The ALC - Automatic Level Control - may be switched in for fuss-free wide-dynamic-range recording. Music Search lets you find the song you want to hear easily.

The tape transport of the CT-5 is controlled by a logic circuit contained in a specially programmed IC . It determines the sequence in which "events" happen. To set the deck in the appropriate button. And we mean touch, because these are all light-touch mode buttons.

The record/play and erase heads are specially designed to match the exacting requirements of metal tape. Sendust reinforced permalloy is used for the former because of its excellent wear characteristics (over 1,000 abrasive hours of use), its resistance to saturation and its high reliability. The latter is a double-gap ferrite type, especially chosen for its high saturation magnetic flux density and high efficiency.

The bulit-in Dolby-C noise reduction system lets you enjoy truly dynamic musical reproduction, free of audible hiss. A switchable MPX (Multiplex) filter eliminates carrier leakage from a faulty tuner so that noise reduction is achieved correctly. Of note to convenience-oriented recordists are ALC and Music Search. ALC automatically adjust an incoming signal to its optimum level during recording so that on playback the program sounds dynamically full and free of objectionable distortion. If desired, the circuit may be switched out and the correct recording level manually set with assistance from the 6-LED bar-graph level display (one per channel). Music Search is a convenient feature that lets you easily locate the beginning of the program you 're presently listening to or the beginning of the next program.

Borrowed from the more expensive models, are such features as Auto Tape Selector, one-Touch recording and timer-assisted recording/playback.

Pioneer CT-4 cassette deck

A Basic Cassette Deck

The CT-4 from Pioneer is an exemplary cassette deck for novice recordists. It's loaded with features to facilitate recording and playback. A case in point is its "power-assisted" tape transport, a feature unusual in a deck in this price range.

Despite being Pioneer's least expensive model, the CT-4 offers touch-operated control buttons, not old-fashioned piano-key type levers. Making this feature possible is the "power-assisted" tape transport, an ingenious Pioneer design that exploits the natural inertia of the rotating flywheel to provide power for mode changes. Heavy-duty, pwer-consuming plungers have been entirely replaced by this simple and dependable mechanism.

As in the more expensive model, a special sendust-reinforces permalloy record/play head is combined with a double-gap ferrite erase head to form a perfect match for metal tape. Each features high wear resistance, low distortion and high reliability. Here's a description of some more features that prove that Pioneer's "basic" deck is not so basic. Set the deck in the play mode and touch the fast forward button.

You're automatically whisked to the beginning of the next selection. Touch the rewind button instead of fast forward and you're back at the beginning of the song currently playing. This amazing feature we call "Music Search". Recording begins by merely touching the record button; you don't need to push the play button at the same time. Recording Mute lets you make blanks between selections without touching the record level controls. If you so desire, you can couple this deck with an optional timer to make unattended recordings or wake up to taped music.

Last but far from least, two electronic features make your recordings sound better. One is the Dolby-C noise reduction system that reduces hiss and expands high-frequency response. The other is the 6-LED bar-graph display (one per channel) that warns of impending tape saturation distortion with electronic responsiveness. As you can see, Pioneer expects a lot from even their basics.

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.
