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.

McIntosh LS360 loudspeakers

 McIntosh LS360

At just more than four feet tall, the magnificent LS360 is the flagship of the Academy Series. Like the CS350, its five tweeters are wired to produce a Bessel Function array. The individual tweeter amplitudes and phase relationships are adjusted so that the array acts as a high frequency point source with a broad dispersion pattern. In addition, the array greatly increases power handling for high frequencies. Two 10-inch LD/HP® woofers and an 8-inch LD/HP ® midrange round out the driver complement. This two bass ports are flared at both ends to form a natural horn and minimize air noise. The tweeters are mounted on traditional McIntosh screened black glass. Natural Cherry, red Cherry, and Black Ash finishes. Exotic woods and finishes available by special order (Piano Black).

The new McIntosh loudspeaker line results from the most ambitious speaker development project in McIntosh history. Never have McIntosh speakers and electronics enjoyed such harmony of quality, performance, and purpose.

With the McIntosh loudspeakers, from the very beginning these models have been designed for low-distortion performance, thanks to patented LD/HP® drivers and unique arched bridge truss cabinet construction. Music benefits from smooth, extended response without the coloration and fuzzy imaging caused by driver distortion and cabinet vibrations. Movie sound benefits from high power handling and fast, clean dynamic response, from the high-output LD/HP drivers.

McIntosh speakers are a true family, sharing a common tonal quality that allows for great configuration flexibility. Virtually any combination of speakers can be used in multichannel applications. High-end loudspeaker in particular are often characterized by just one aspect of their performance. It could be bass response, treble transparency, depth of image, cosmetic appearance, or even price. In all of its products, however, McIntosh seeks balance, and so is the case with speakers. McIntosh speakers certainly have an extremely smooth and broad frequency response, and they do “measure” well in front of a microphone and spectrum analyzer. But in the final analysis, they are distinguished by their sheer musicality, which can only be measured by listening.

LD/HP® Drivers

In LD/HP driver, a pair of aluminum shorting sleeves makes the magnetic field more symmetrical and reduces distortion. The sleeves also lower the impedance of the voice coil, permitting greater current flow and hence higher output levels.

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.
