Technics RS-B665 cassette deck

Technics RS-B665

Quartz Direct Drive Stereo Cassette Deck

the RS-B665 direct drive cassette deck clarifies the Technics technological lead in this realm. The motor uses an improved planar opposed design for its amazingly high torque while individual balancing of each flywheel prevents torque ripple. For precise servo control, the RS-B665 digitally compares the motor’s FG pulse to a quartz reference frequency. This direct comparison greatly improves rotational precision. So musical details come through in their original pure state.

2-Motor Tape Transport

A division of labor results in greater reliability of the tape transport mechanism. The high-torque DD motor drives the critical capstan, while a second motor drives the supply and take-up reels. Microprocessor full-logic control coordinates motor activity for smoothly integrated task performance.

Linear Magne-Field Class AA Circuit

Located after the recording amp. The Linear Magne-Field Class AA circuit overcomes the typical non-linearity occurring during electromagnetic transduction in the tape heads. The key is a refinement of the Technics Class AA circuit technique which prevents phase shift and avoids loss of mid-to-high frequency gain caused by head-coil inductance.

Dolby HX pro

HX Pro extends the headroom of virtually any tape, allowing it to record more high frequency information without overloading and causing distortion.

PXS Capacitors

Developed specially for improved sound quality. PXS capacitors are employed in various locations in the deck circuitry, including the power supply. This new technology helps preserve the fidelity of the original audio signal

Bias Fine Adjustment

You can “fine tune” the recording bias to maximize performance of your favorite tape formulations (Normal, cro2)

APRS (Advanced Precise Rec Level System)

Now APRS simplifies location of the ideal recording level. Since the meters hold the highest peak reached in your source program, you simply adjust the rec-level knob until the meters indicate the optimum setting. Great for use with the peak level search function in Technics CD players.

Dual-Range Peak-Hold Meters

For fine adjustments of recording level you can switch the meter range so that it indicates a range from -7 dB to +8 dB in 1 dB steps (instead of the usual -30 dB to +16 dB )

Linear Electronic Counter with memory Stop/Repeat

This 4-digit display shows elapsed tape time in minutes and seconds. Or you can switch it to work as a 3-digit counter. In whichever counter mode, you can have the tape stop automatically at the “00:00” or “000” position. Repeated play is also possible

Toshiba PT-490 cassette tape deck

 Toshiba – Now you can record on a Dolby cassette deck for 2 straight hours without flipping the tape.

Recording Beethoven’s  4th, 5th and 6th on one continuous taping. Or playing a two hour tape of The Beatles without even being in the same room. Or catching yourself in duet with Brubeck and not having to stop flip the tape. Well, if your cassette deck is a Toshiba PT-490 with the automatic reverse feature it’s easy.

Just set the Mode dial and the machine knows exactly what you want it to do. Whether you want it to record one side of the tape and then stop. Or play and turn itself off. Or record both sides of the tape for two uninterrupted hours. Or play back the same tape indefinitely. The machine does it all for you. And it does it automatically.

In addition to reversing its own tape, the PT-490 also gives you outstanding performance and sound. That’s because it comes with Dolby noise reduction. Mechanical auto shut-off. Separate record and playback volume controls. Two large, illuminated VU-meter. And a bias selector switch for normal, hi-fi and CrO₂ tape. And it’s one more example of the fine craftsmanship that goes into all Toshiba products.

Kenwood KX-700 cassette deck

Stereo cassette deck with Dolby noise reduction system

A state-of-the-art. Cassette deck with reel-to-reel quality featuring

Luxurious in every respect, the KX-700 combines reel-to-reel quality with cassette convenience. Its patented Dolby Noise Reduction System (Type B) virtually eliminates high frequency background noise without affecting high frequency signals. The superferrite record-and-play head, with its precision micro-gap, utilizes bias frequencies to optimum advantage for top quality reproduction, and a three-way Tape Selector permits a choice of the correct bias for Regular, Low Noise or Chromium Dioxide tapes. A measure of the unit's fine performance is indicated by a few of its excellent specs.

 

Special features

Patented Dolby Noise Reduction System - will filter out high frequency background noises (hiss sounds) inherent in the recording process, or will play back pre-recorded Dolbyized tapes with an almost silent background, improving Signal-to-Noise Ratio by approximately 10 dB for all tape types.

Super-Ferrite Core head - is made of high density and extremely hard ferrite magnetic material to provide exceptional long life. The material permits the fabrication of an extremely narrow, precise head gap that allows bias frequencies to be utilized to optimum advantage in the recording and reproduction of high frequency sounds. The unit also incorporates an erase head.

Three-Way Tape Selection Push-Button Switch - permits a choice of the correct bias frequency for Regular, Low Noise or Chromium Dioxide Tapes, providing maximum flexibility in achieving the finest sound reproduction from each tape type.

Slide Lever Volume Controls - two separate left and right slide Lever Controls for Record and Play offer easy accurate level adjustment.

Two Large VU Meters - one for each channel are easy to read for accurate level check

Three Digit Counter - with re-set button provides tape location at a glance

Piano Key Controls - provide feather-touch control for Eject; Stop; Reverse; Play, Fast Forward, Record and Pause. The Pause function is particularly convenient for tape editing

Input/Output Terminals - provide maximum convenience, with 2 Microphone jacks, Phone jack for 8 Ω  stereo headphones; DIN connector, and Line-IN/Line-Out Terminals.

Low-Distortion, High S/N Preamp - use of 2 FETs in the first stage of preamplification and 14 silicon transistors having low noise, high gain characteristics assure low distortion and a high Signal-to-Noise Ratio.

Automatic Stop - at tape's end in any mode recording, playback fast forward, or reverse, the KX-700 will automatically stop, with the pinch roller lifted away from the capstan to prevent any capstan displacement.

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.

For example, it uses Sen-Alloy heads. These JVC-developed heads handle tremendously high currents with ease, so they're especially well  suited for recording and erasing metal tape. And SA's superb electromagnetic and physical properties give you accurate frequency balance, superb extension and low distortion through years of use.

When you use metal tape with the KD-A33, you'll get all the performance you expect from metal . But when your budget  dictates using a less expensive ferric-oxide tape, you can still get metal-like sound thanks to another JVC development - Super ANRS.

In recording, Super ANRE reduces the level of high-frequency signals so the tape can handle them without, saturating, in playback, it boosts them back to their original level. As a result, sounds like cymbal crashes, trumpet blast, and spoken sibilants (normally the downfall of cassette recording) are reproduced with astonishing clarity and fidelity to the original

 

 

 

And like our most expensive decks, the KD-A33 has logic-governed solenoid transport controls. You can switch directly between modes, even from "rewind" to "fast forward" with just a light touch of a switch. The KD-A33 also has provisions for adding a timer device and optional remote control.

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.
