Electronics

The control system in the 9100X is an electronic brain with 14 high level logic, integrated circuits (IC’s). electronics has replaced mechanics, and each control is carried out firmly and precisely by a light touch on the keyboard 9100X “thinks for itself”. The electronics and the tape-tensioning mechanism always ensure that the tape is transported correctly. Connected to a remote control system (an accessory) all logic functions can be controlled from a distance of 5 meters. 9100X has all the qualities that Tandberg tape recorder are renowned for; echo, recording with sound-on-sound, A- and B-test of programmes. The B-test is a particularly important feature because it facilities close control of recording quality. There are 4 input controls, 2 for microphone inputs and 2 for line input (radio with record player or another tape recorder), and sound sources in stereo or mono. The microphone inputs in 9100X are balanced. This means that unwanted electrical noise from e. g. vacuum cleaners or foodmixers does not affect the recording.

Tandberg Crossfield Recording Technique

This is a special recording technique found only in Tandberg tape recorders. With this technique the tape is magnetized right through and is therefore capable of receiving very strong signals and reproducing them as crystal clear sound without distortion. The Tandberg Crossfield recording technique provides a safety margin against overload, particularly in the highest tone register which is the most critical region when recording.

Peak Level  Meters

The level meters are in the professional class. They always shows the strongest part of the sound – exactly that part which becomes distorted if the magnetic tape is overloaded. With the Tandberg Crossfield recording technique and the peak level meters you can fully exploit a tape’s qualities.

Photo-electric Stop

The forward drive stops automatically at the end of the tape or if the tape is transparent

Monitoring During Fast Winding/Editing

This functions (Edit/Cue) facilities listening to the tape during fast winding or rewinding. Consequently it is easy to find your way on the tape and to edit the recordings

Professional Mechanics

Correct reproduction demands high accuracy in the design and construction of the tape path. Therefore the complete tape guidance system in the 9100X is mounted on a stable base plate which ensures that the tape is correctly guided passed the magnetic heads. There are 3 motors – 2 for winding in either direction and one for forward drive. The winding motors work also as mechanical breakes. Together with the closed loop and the magnetic controlled friction breakes they ensure gentle treatment of the tape.

Garrard DD-132 turntable

 The Garrard DD132

Direct drive, single play turntables with Fail-Safe Drive System, low-mass tracking and Delglide automation

The Garrard name in turntables is legendary. With the new direct drive, single play DD132, Garrard introduces two models that reflect the achievements of generations of turntable engineering. Both models are precise expressions of the critical elements that determine exquisite reproduction of music.

Critical Element – The Drive System

It’s called the Fail-Safe Drive System, and for good reason. From its motor, through its speed monitoring, it functions to eliminate the distortions caused by speed irregularities before they can reach the listener’s ear.

The motor is the heart of any direct drive turntable. The DD132 (and DD131) incorporate a DC servo-controlled motor which revolves at the same speed as the platter. But that’s only the first step.

The new Garrard motor an end to cogging

The new direct drive motor, designed and built by Garrard, is brushless coreless and slotless. Most important, it puts an end to the problem which plagues most direct drive motors cogging. Cogging lakes place because the space or “slots” between the magnetic poles of a motor exert a different force than the poles themselves. The result is erratic rotation and rumble. This new Garrard motor ends cogging. It exerts a constant magnetic force during the entire 360(O) rotation of the platter.

Time-Integral-Velocity monitoring

Monitoring of the motor is accomplished by a state-of-the-art speed detection system we call Time-Integral-Velocity Simply stated, a signal is generated which reveals actual rotational speed so that it can be read by correction circuitry.

“Hall effect” circuitry

Final assurance of rotational speed is accomplished by “Hall effect” circuitry which makes instant correction of any irregularity whether caused by stylus drag, cleaning devices or other factors which threaten to interfere with the speed you’ve chosen. Summation Garrard’s Fail-Safe Drive System provides a cogless motor, constant monitoring and instant correction.

The Tonearm

It is unfortunate and somewhat surprising that so many manufacturers still ignore the vital role of the tonearm in determining performance. Garrard engineering has paid special attention to the tonearm. Both the DD132 (and DD131) boast the same tonearm/headshell combination. Tonearm and headshell together weight just 12 grams. Thus you can derive the full potential of any cartridge including the new, low-mass, high compliance types that are finding increasing favor among audiophiles and music lovers. Julian Hirsch the noted reviewer; said that the Garrard tonerm is compatible with any cartridge presently manufactured , no matter how compliant it may be.

Silent Automation

The new Garrard direct drive motor and ultra-light tonearm in the DD132 (and DD131) are integrated with the exceptionally silent smooth and dependable Delglide system. The reviews tell the story. Stereo magazine “everything worked perfectly, and with impressive silence and smoothness”. Radio Electronics “ one the smoothest changing cycles we have ever seen”. Audio magazine  “ very quiet in operation, should give years of trouble-free service.”

Summation

The DD132 (and DD131) direct drive turntables include Garrard’s Fail-Safe Drive System, an ultra-light tonearm with magnesium headshell and an astonishingly silent automatic system. In addition, both units incorporate variable speed control and a stroboscope illuminated by an LED for easy reading even in a brightly lit room.

Design and styling

The controls of both of these turntables are expressions of Garrard’s concern with “human engineering” they are grouped in sensible operating sequence and each control is clearly marked and generously sized for the adult hand.  Their circular(rather than push-button or slide) action allows use of the controls while a record is playing without jarring the tonearm. Either of these turntables can be placed in any room and beautifully integrate with its décor.

The difference

The tonearm of the DD132 will automatically index, lift and the end of play and come back to its rest before shutting off. The DD132 also features repeat play capability.

Garrard DD-130 turntable

Garrard DD130 

The DD130 is designed for music lovers whose major concern is the fidelity with the music on their records is reproduced. It is a direct-drive, single play, manual turntable with a low mass, professional tonearm. The quality of its elements ensures an exceptionally high level or performance.

The tonearm

Garrard engineers have given special attention to the DD130 tonearm. The critical importance of this element is frequently overlooked by many manufacturers of direct drive turntables

It must be remembered that the tiny stylus, as it traces the groove, must bear the full weight of the tonearm. Clearly a tonearm must be light and ensure that the finest and lightest tracking cartridges can be used with optimum results. The tonearm of the DD130 is tubular and made of an aluminum alloy formulated for lightness and rigidity. The head shell is made of ultra light magnesium. The tonearm and headshell together weight a mere 12 grams. To underscore the assurance of quality reproduction, the tonearm “rides” on jewel bearings. The DD130 will readily track records that are badly warped. Something tonearms of higher mass simply cannot do.

The direct drive motor

The performance of a direct drive turntable rests heavily upon the motor, since the platter is directly attached to the motor shaft. The DD130 boasts a brushless DC motor, operating at low speed which sharply reduces mechanical vibration. In the DD130, the standard 110 volt, 60 cycle AC is converted to 16 volt DC. Thus the motor is immune to the normal fluctuations in the voltage or frequency of house hold current.

Servo electronic Control

The design of the DD130 motor, results in smoother rotation than is possible with more conventional motors. To ensure that speed is maintained precisely an automatic speed controlled is incorporated. Rotor speed is converted into voltage. The faster the speed, the higher the voltage. This voltage is monitored by a servo circuit which senses the most minute variation from correct voltage. It then automatically alters the amount of current, correcting variations instantaneously.

Variable speed control

Are your ears sensitive enough to detect an off-pitch recording? By means of a variable pitch control, you can alter the speed of the platter to correct the faulty recording. An easy-to-read, LED-illuminated stroboscope provides visual confirmation when you want to go back to normal accurate speed.

More features

The four-pound, die-cast aluminum platter assures clean-level rotation. A full 12 inches in diameter, it is dynamically balanced. The DD130 features a calibrated (for elliptical and CD4 styli) anti-skate control. This control enables the listener to neutralize the force which tends to press the stylus against the inner wall of the groove while a record is spinning. The precise anti-skate control of the DD130 will keep the stylus centered in the groove.

The controls of the DD130 are clearly marked strategically positioned and easily operated. It is mounted on a glass-filled, polyester, “Slim-Line” base. The base stands on shock-absorbent feet that insulate the DD130 from external vibration. A sleek, moulded dust cover is attached to the base via special friction-fit hinges.

Finally, the appearance of the DD130 complements its performance. Its colors were chosen to blend gracefully with any décor. Performance, appearance, price and reliability. The DD130 is a manual turntable for the listener who is more than casual about music.

Garrard GT-20 turntable

 The fact that the belt-driven manual turntable GT20 is the most affordable in our series may have led you to believe that we have cut corners on traditional Garrard quality.

They couldn't have been further from the truth. Consider, first of all, that it has the exact same ultra-low-mass S-shaped tonearm as our most expensive direct-drive model, and the same precisely calibrated anti-skating device to eliminate unwanted centrifugal forces.

And the same jewel-encrusted, ultra-fine pivot bearings that virtually eliminate friction, allowing you to use the highest quality cartridge systems. Consider also the heavy, die-cast aluminum platter, which is dynamically balanced for exceptionally smooth operation. And finally, consider the exquisite design, which is on par with the other models in this series.

Luxman PX-101 turntable

 Luxman PX-101

Fully Automatic Tangential Tracking Turntable

The PX-101 plays back records exactly as they were cut; in a straight line. Essentially providing zero-deviation from the cutting process, as well as zero tracking error and zero tracking distortion during playback.

The advantages of tangential tracking are immediately evident. The music sounds “cleaner”, with better separation between channels, better separation of instruments within the orchestra, and a far more vivid recreation of the “soundstage”.

With the PX-101, wow and flutter is inaudible. Rumble, non-existent. Speed of 33-1/3 and 45 RPM, with a ±3% deviation available at will. Both the tonearm and headshell are constructed of improved aluminum alloy for resonance-control and damping. Fully automatic, direct-drive, it requires but a touch to operate. A built-in circuit of the PX-101 will automatically place your accompanying Luxman KX-101 or KX-102 cassette deck in the pause mode when the record you’re recording has reached the end of play. And the PX-101 is also responsive to the Infrared Wireles Remote Control system of the new Luxman RX-103 Receiver.

Features:

Tangential Tracking System – The straight tone arm of the PX-101 tracks in a straight line from the outer grooves to the inner grooves of a disc, exactly as the disc was cut. This virtually eliminates tracking errors and inside force problems; giving better stereo separation, and a more vivid recreation of the recording “soundstage”. The high performance tonearm is driven by a separate tonearm control motor, which is superior in its construction of computerized control circuits and improved stainless steel wire.

Optical Sensing Fully Automatic Function – Fully automatic, smooth, accurate response is ensured thanks to the exclusive integrated Circuit TIP and Optical Sensing Circuit. (Detection of the auto return point occurs without side-force.) Press the Start/Cut button after selecting the speed. Automatic lead in and lead out of the tonearm is activated by Feather-Touch Control. Interruption of operation during play is made easy by pressing the Start/Cut button. The tonearm automatically returns to the armrest and shuts off the motor. In the “Repeat” position, playback of the same record is endlessly repeated.

Auto Disc Pause – When activated, a built-in circuit of the PX-101 automatically places your accompanying KX-101 or KX-102 cassette deck  in the pause mode from the record mode, when the record being taped reaches the end of play. Allows you to leave the system unattended while taping.

Remote Control Capability – In combination with the RX-103 Receiver, the PX-101 Turntable may be controlled through the RX-103’s infrared wireless Remote Control. The Remote Control activates the turnable’s play, cut, cue up, and cue down functions.

Electrical Cueing and Arm Speed Switches – A touch of the Cueing Switch controls the tonearm, up and down. The Arm Speed Switch allows you to move the tonearm into position over the exact cur desired on the disc. A slight touch and the arm moves slowly; a further touch and the arm moves faster, either toward the inside or outside of the disc.

External Control Board – The controls are located outside of the dust cover, to protect discs while in play.

Detachable Head Shell – Cartridges are easy to install. The PX-101 accepts a variety of cartridges and other standard universal head shells.

Mirror Reflex Stroboscope – The unique Stroboscope system of mirror-reflection makes adjustments on accurate feed rotation easy.

Pitch Control – The speed can be adjusted by tuning pitch control up to ±3%

Dual 1229Q turntable

Motor and Pulley

Power for the turntable platter and the changing mechanism is supplied by a four—pole Dual continuous pole synchronous motor suspended by radially located elastic mounts and having a very small stray magnetic field and little vibration. The speed of the motor is independent of line voltage, temperature or load variations. Speed is dependent on, and proportional to power—line frequency. The motor is adapted to 50 or 60 cycle (Hz) power—line frequencies by the correct choice of motor pulley.

The motor pulley is fastened to the motor shaft by a setscrew. When you change pulleys, be sure that the new pulley is set at the correct height The turntable platter is driven by the idler wheel, which, to prevent damage to its friction surfaces, is automatically disengaged when the unit is shut off. Setting the turntable speed to 33 1/3, 45 or 78 rpm is done by raising or lowering the idler to bear against the proper step of the motor pulley. Upon actuation of the switch, the switch segment rotates. This causes the lever fitted into a slot on the segment to move vertically. The drive wheel carried on the swinging arm is then lifted off the motor pulley, moved and replaced on the motor pulley step corresponding to the selected speed.

Tonearm and Tonearm Bearing

Tubular tonearm, extra lightweight, torsionally rigid tonearm of the Dual 1229 Q pivots both horizontally and vertically on needle bearings and precision ball bearings in hardened and polished races. lt is suspended in a gimbal arrangement. This keeps friction to a minimum.

Vertical pivot friction = 0.007 gram

Horizontal pivot friction = 0.015 gram

referred to stylus tip

The arm is thus able to track extremely well. The tonearm head is removable. Before setting the tracking force for the cartridge being used, set the tracking—force scale to zero and balance the tonearm. Initial balance is by sliding the counterweight .Final adjustment is by turning the weight. You can balance cartridges with a weight of 1 to 10 grams.

To reduce the effects of small shock impulses on the arm, the counterbalance weight is resiliently mounted on a threaded spindle, and friction—braked to prevent accidental rotation. The cartridge holder will accept all cartridges with international standard mounting centers of 1/2 inch. Stylus force is set by turning a calibrated housing which stresses or releases a spiral spring contained inside. The scale adjustment is calibrated from 0 — 3 p, from 0 — 1.5 p at 1/10 p and from 1.5 — 3 p at 1/4 p intervals. Tracking forces of mors than 3 p can be adjusted with the help of the counter—weight on the tonearm; turning left (counter—clock—wise) increases the tracking force by 1/2 p per complete turn.

Dual 1228 turntable

 Motor and Drive

Power for the turntable platter and the changing mechanism is supplied by a four-pole, split-pole synchronous motor suspended by radially located elastic mounts and having a very small stray magnetic field as well as little vibration.

The speed of the motor is independent of line voltage, temperature or load variations. Speed is dependent on, and proportional to, power line frequency. The motor is adapted to 50 or 60 cycle (Hz) power line frequencies by the correct choice of the motor pulley.

The platter is driven by the idler wheel which is automatically disengaged from the motor pulley when the unit is shut off in order to protect its driving surface.

Platter speeds of 33-1/3 and 45 rpm are selected by raising or lowering the idler wheel to the appropriate step on the motor pulley.

Tonearm

The Dual 1228 has a light, torsionally rigid metal tonearm in a gimbal type suspension. The actual support is provided by four hardened and precision-polished steel points resting in precision ball bearings. Tonearm pivot friction is thus reduced to a minimum.

It therefore guarantees exceptionally good tracking characteristics. The tonearm head is removable. Before setting the correct stylus force for the particular cartridge installed in the tonearm head, the tonearm should be balanced with the stylus force setting dial at the zero position. Coarse balancing is accomplished by sliding the counterweight and using setcrew, after which a fine adjustment is made by turning the weight. The counterweight is proportioned so that cartridges with a weight of from 1 to 12 grams can be balanced. For the absorption of vibration and rapid small shocks, the counterweight is coupled to its threaded shaft through an elastic medium, and braked to prevent unintended rotation. The tonearm head accommodates all cartridges that conform to the internationally standard ½ inch mounting centers, and whose weight does not exceed 10 grams. Stylus force is set by turning apring housing, which is equipped with calibrations and which stresses or relaxes a spiral spring inside it. The scale is calibrated for a range of zero to 5 grams, and permits exact settings every 0,5 gram within that range.

Technics RS-M250 cassette deck

 Technics RS-M250

A new cassette deck from Technics, the RS-M250 , is packed with a tremendous variety of convenience and handling features. And, as with all technics cassette decks, its performance represents excellent value – the RS-M250 is capable of making recordings which are virtually indistinguishable from the original program source. In fact, on a price/performance basis, Technics products traditionally have compared quite favourably with those of our competitors. The new Technics cassette deck line is no exception – it offers outstanding value at all price levels.

Versatile Microprocessor

Simply turning on the power will show you that the RS-M250 is different from other cassette decks . notice, for example, the digital tape counter. The readout is large and bright, and can be seen from across the room. One count of the counter corresponds to 2 rotations of the reels. Yet it is more accurate than many similar devices because it includes 4 fractional divisions which break down the readout more precisely – half-turns of the take-up hub can be accurately measured. But the readout is only part of the story.

Suppose you want to repeat a track on the tape, or refer back to any point on the recording. It’s easy with the RS-M250 and its microprocessor. The memory has four settings; “stop”, “off”, “play”, and “repeat”/ in the “repeat” mode , you simply press the reset button at the point on the tape you want to recall. Then, a touch of the rewind button will return the transport to this spot, where it will automatically switch into play. If allowed to continue and play the remainder of the side, the microprocessor will then instruct the transport to return to “000” where, once again, playback begins. “Play” works the same way, except that it doesn’t repeat, and “stop” simply returns the tape to the “000” point without beginning playback. For checking recordings, or finding an exact point on the tape for future reference, the RS-M250 is a very convenient deck at a reasonable price.

Effortless, Error-Free Mode Changing

The transport controls are logic-controlled switches. There’s no need to use the stop button when changing modes – just go directly into any mode (except record), including rewind, fast forward, and play. And when recording, a touch of the record button also engages both the play and the pause mechanisms automatically – then just touch the play button to begin recording. Thus, you avoid the difficulties and inconvenience of having to engage all these controls separately and manually.

If you want even more convenient operation, use the optional RP-9645 remote control module. You can control all transport functions, plus record muting, from the comfort of your listening position. There is even a convenient front panel input jack for connecting the remote control unit; when not in use, a special cover protects the jack from dust and impurities.

Simple-to-Use Features

We believe that convenience features are worthwhile only if they are easy to use – all the RS-M250’s features can be engaged and used with a minimum of effort. For example, we provide a switch which allows the use of an external timer, and the hook-up is extremely simple – the entire operation can be controlled from the front panel. The same point of view explains the door on the cassette well.  It is removable for easy access to the heads for examination or cleaning. No bolts or screws – the door simply slides into place. As you can see, the RS-M250 is designed for simple operation of all functions.

Performance

Of course all the features in the world aren’t worth much if the deck lacks good basic performance characteristics. Fortunately, the RS-M250’s performance is superb, particularly in light of its modest price tag. A glance at the spec table will demonstrate our devotion to quality. And the tapes which you make with the RS-M250 will sound consistently clean, crisp, realistic, and natural. We have also included the necessary extras to ensure this excellent performance undervirtually any circumstances.

Meters

For example, our FL peak reading meters employ a peak hold readout – this means that peaks are retained on the meter for 2 seconds. Then the meters automatically reset until the next peak comes along. The 2 color readout clearly indicates the 0 dB point, so you can be sure that the recording level will always be accurate. Result? Tape recordings with low noise, low distortion, and superb fidelity.

Tape Selector Switch

Naturally, we have included a selector switch to set bias and equalization for metal tape , the latest technological advance in the cassette medium. This formulation also necessitated an improvement in the saturation flux density of the recording head itself – our improved SX record/playback head yields exemplary performance with any type of tape. The Sendust formulation also assures a long life for the head with only normal routine maintenance.

FM Recording

Recording a program from an FM signal source will also yield a very high quality recording. The front panel MPX filter switch removes the carrier pilot signal from the tape input, thereby avoiding the distortion associated with this signal.

The Technics RS-M250 – an excellent combination of fine basic performance and the features to make the deck flexible enough for a wide variety of applications. Plus, it includes something which has become a Technics tradition – outstanding value for the money.

Other Features:

2 motor drive system – one for driving the capstan and another powers the reels and the head block during transport mode switching. This system contributes to low wow and flutter and good reliability.

Input selector switch – allows you to choose between “line” and “mic” inputs. If “mic” is selected, you can utilize the 2 front panel microphone jacks.

Dual concentric input level controls – friction coupled knobs, for adjusting one channel at a time, or both together.

Output level control – useful for matching the volume output of the deck to that of your tuner and turntable, so there’s no need for repeated adjustments in volume

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.
