Speaker/Room Interaction Covered In Allison Catalog
A ten-page catalog from Allison Acoustics devotes several pages to a description of room-boundary influences on the in-room performance of conventional loudspeakers. Allison's approach to the problems created by these effects is also discussed, together with the rationale behind the design of the Allison mid-range and high-frequency drivers. The remainder of the booklet covers the company's four loudspeaker models in some detail, finishing with performance data on the individual drivers used in the system and some notes on low-frequency distortion. The catalog is available free from: Allison Acoustics Inc., Dept. SR, 7 Tech Circle, Natick, Mass. 01760.
Offer Miniature Engraving of Early Talking Machine
To commemorate the hundredth anniversary of sound recording, the U.S. Government has commissioned an illustration of an early Edison phonograph, reproductions of which are being offered to the public for a nominal sum. Depicted in three colors on sturdy government-approved stock, the antique cylinder instrument has the crank-handle/flywheel/mouthpiece construction that typifies recorders of the cylinder era (the familiar horn assembly often used for playback is not shown).
The picture's small size (roughly 1 1/2 x 1 inches) makes it eminently portable and convenient to carry in wallet or purse. For permanent installation, adhesive on the back of the picture permits affixing it to any smooth surface, including the envelopes of first-class postal correspondence, on which it confers the useful ability to pass through the U.S. mails unimpeded. The phonograph illustration is available singly or in various combinations, including sheets of one hundred. Perforations decorate all four sides. Price: 13¢ each.
"Linear Phase" Speaker Systems From Technics
The three systems comprising Technics' current line of "Linear Phase" loudspeakers give special attention to driver spacing, cross over characteristics, and driver phase/amplitude response. The individual drivers are spaced vertically to be as close together as possible, while their distances from the listener are staggered to equalize their acoustic path lengths. Crossover networks, matched to the drivers used, combine low-pass, high pass, and band-pass elements to provide a smooth phase transition at the crossover frequencies. The wide-range drivers employed are limited to bandwidths that are effectively free of phase anomalies.
The Model SB-7000A (shown) is a three way system (13 3/4-inch woofer, 4 3/4-inch cone mid-range, and 11/4-inch dome tweeter), in a ported enclosure, with a nominal impedance of 6 ohms. Crossover frequencies are 700 and 6,000 Hz. At a distance of 1 meter, the system produces a sound-pressure level of 90.5 dB with a 1-watt input; it is rated for peak inputs of 150 watts. Level controls adjust mid-range and tweeter outputs by varying the "Q" of associated resonant circuits, which is said to avoid many of the effects of conventional controls on phase integrity. The cabinet is clad in black vinyl material, surmounted by a black "sub-enclosure" for the mid-range and tweeter. Overall dimensions: 33 1/4 x 19 x 16 1/4 inches. Price: approximately $400. Two other Technics models, the SB-6000A and SB-5000A, are two-way systems based on the same design philosophy, with approximate prices of $300 and $160.
Mitsubishi's "Docking" Preamp and Power Amplifiers
The Mitsubishi DA-P10 preamplifier and the DA-A15 (150 watts per channel) or DA-A10 (100 watts per channel) are designed to interconnect or "dock" via special mating connectors on their respective rear and front panels. When so connected they form a unit less than 17 inches deep, 163/4 inches wide, and 6 3/4 inches high. The Mitsubishi products are described as "dual-monaural" components, meaning that virtually all circuits and controls (bass, treble, level, and subsonic filter in the P10 preamplifier) are completely separate for the two channels. At their rated power outputs (for 8 ohms, 20 to 20,000 Hz) the two power amplifiers have 0.1 percent harmonic and intermodulation distortion and signal-to-noise ratios of approximately 100 dB. For the preamplifier, harmonic and inter-modulation distortion are 0.02 percent at the rated output of 1 volt into 50,000 ohms. Signal-to-noise ratios are 73 (phono) and 90 (high-level) dB.
The power amplifiers contain circuits to protect against abnormally low load impedances and to prevent d.c. voltages from appearing at their outputs. Both have completely separate power supplies (including separate power transformers) for their two channels.
The preamplifier also has separate power sup plies, deriving line voltage from isolated windings on a single power transformer. Prices: DA-P10, $290; DA-A10, $390; DA-A15, $590.
McKay Dymek All-wave Communications Receiver D The McKay Dymek DR-22 is a frequency-synthesizing AM unit that will receive all broadcasts between 50 kHz and 29.7 MHz, including AM stations, short wave, amateur radio, and Citizens Band, along with upper and lower side-band, continuous-wave, and tele type reception. The phase-locked-loop tuning system works together with combinations of crystal and ceramic filters to provide a maximum of selectivity and high resistance to cross modulation.
A prominent feature of the DR-22 is a five-figure LED digital frequency indicator. A front-panel switch permits the user to choose an audio bandwidth of 8,000 or 4,000 Hz, the latter providing an increase in selectivity.
Tuning is by means of four rotary selector switches and a fine-tuning control with a range of-±5 kHz. The tuner has a small built in power amplifier and speaker, connections for an external speaker, and an output for connection to an external audio system.
There is also a front-panel headphone jack.
The tuner comes with teak side panels; rack-mounting accessories are available. Dimensions are approximately 17 1/2 x 5 x 16 inches. Price: $995.
Deluxe Electrostatic Headset Begins Koss "Auditor" Series D
The ESP/10 electrostatic stereo head phones, successor to the illustrious ESP/9, is the start of a new Koss headphone line to be entitled the "Auditor" series. The ESP/10 consists of two parts: the headset itself, with circumaural foam-filled ear cushions and an adjustable padded headband attached through pivoting yokes, and an energizing unit in the form of a small console accepting up to two headsets. The energizer, which plugs into a standard a.c. outlet, is in turn connected to the speaker outputs of a stereo amplifier (a minimum of 35 watts per channel is recommended to realize the full dynamic-range potential of the headphones). It has "semi" peak-reading meters for each channel, plus a relay that cuts off the signal to the headset in the event of excessive drive level. The relay resets itself automatically after a few seconds' pause; a red LED on the energizer lights when the relay has tripped.
The ESP/10-headset has electrostatic diaphragms with radiating areas of 3.8 square inches per side. Usable frequency response is 10 to 22,000 Hz within ±2 dB of Koss' "ideal" response for headphones. A sound-pressure level of 100 dB is achieved for an input to the energizer of about 2 volts rms.
Harmonic distortion for that level at 1,000 Hz is less than 0.5 percent. Excluding cable, the headset weighs just under 1 pound. Price of the ESP/10 (energizer plus a single headset): $300.
The PS-58 is a two-speed (33 1/3 and 45 rpm) "Uni-torque" direct-drive machine with fully automatic operation. The S-shaped tubular tone arm has its own motor to insure complete isolation from the platter-drive system.
The 12-inch aluminum platter, weighing 3 1/2 pounds, carries a stroboscopic pattern on its edge, illuminated by a lamp to indicate any speed error. Separate adjustment controls for the speeds operate over a 5 percent range.
A single lever control selects manual or automatic operation and initiates the automatic cycle. Two other controls-one for tone-arm cueing (fully damped) and the other for selecting record size (diameters of 12, 10, or 7 inches)--are also provided. Tracking force is applied by a calibrated counterweight on the tone arm; the antiskating adjustment is separate. Wow and flutter (weighted) are 0.025 percent; rumble (DIN B weighted) is-74 dB. A hinged dust cover is also supplied, resulting in dimensions of 18 3/4 x 6 1/2 x 14 1/2 inches. Suggested price: $300.
Analog's Modular Preamplifier
The Analogue 520 from Analog Engineering Associates has all its signal-handling circuitry contained in six epoxy-encapsulated modules. These in turn plug into connectors on a large printed-circuit board that fills al most the entire chassis; all controls (environmentally sealed) are also affixed to the board.
The 520 has inputs for two phono cartridges, tuner, auxiliary source, and inputs and tape-monitoring circuits for two tape machines.
Harmonic and intermodulation distortion are less than 0.004 percent for both the phono and the high-level sections, referred to an output level of 2.5 volts at the main outputs. Signal-to-noise ratios (unweighted) for the two sections are 80 and 90 dB, respectively. Frequency response throughout the preamplifier is flat within +0,-0.5 dB over the full audio range. The 520 has a maximum output of 7.5 volts, and a load of at least 30,000 ohms is recommended. Dimensions: approximately 15 x 4 3/4 x 11 inches. Price: $590. Oak or oiled-walnut cabinets are available as options.
American Audioport has become exclusive distributor for the Entre-1, said to be the lightest (at 5.8 grams) moving-coil stereo pho no cartridge available. For a standard recorded level the cartridge has an output of 0.2 millivolt; it presents a source impedance of 3 ohms. Recommended tracking force is 1.8 grams. The Entre-l's stylus is described as a modified elliptical configuration with a vertical tracking angle of 20 degrees. Frequency response is 10 to 50,000 Hz. Retail price: about $200.
Micro-mini Speaker System by Royal Sound
Especially suited for mobile applications, the Royal Sound RS-6040 has a cast aluminum enclosure measuring a compact 6 1/2 x 4 1/4 x 4 1/2 inches. The driver complement consists of a 4-inch air-suspension woofer and a 2 3/4-inch dome tweeter, resulting in a system with an impedance range of 4 to 8 ohms and a power-handling capacity of 20 watts. The crossover frequency is 2,800 Hz; frequency response is rated at 50 to 22,000 Hz. The speaker weighs 4 1/4 pounds and comes with a 9-foot connecting cable terminated by a DIN speaker plug.
Available finishes are black or natural. Price: $200 per pair.
Dual Adds Three Automatic Turntables
All three of Dual's latest automatic turntables are belt-driven, and all three, feature the four-point gimbal tone-arm suspensions that have distinguished the top-of-the-line Dual machines. Two speeds (33 1/3 and 45 rpm) are provided, and speeds can be fine-tuned over a range of 6 percent by means of a pulley that can be varied in its effective diameter. The Model 1245 (shown) has a stroboscopic indicator in the form of indentations cast into the edge of its 12-inch platter, illuminated by a strobe lamp. It is provided with base and dust cover at a price of less than $230. The Dual 1241, also with a 12-inch platter, is priced at under $200, base and dust cover included.
The dimensions of the units installed on their bases are 16 3/4 inches wide, 14 1/2 inches deep, and 7 3/4 inches high with dust cover. The Model 1237 has a somewhat smaller platter and chassis than the other two units and is priced at under $135, with base and dust cover costing less than $30 additional.
All three machines have damped cueing mechanisms and antiskating adjustments calibrated for conical, elliptical, and CD-4 styli.
The tone arms are of a straight tubular design, with stylus force applied by a calibrated spring mechanism after the arm has been balanced by means of a rotating counterweight.
The record-changing spindles for all three machines accommodate up to six records; manual spindles that rotate with the platter are also provided.
Complete Audio System Includes Equipment Cabinet
MGA has announced a complete component audio system, including several options, that is supplied with a free-standing rosewood cabinet to house the electronic components as well as a selection of record albums. The ensemble, called the "Series E System Components," begins with the belt-drive DP-200 single-play turntable, a unit with speeds of 33 1/3 and 45 rpm that comes with a magnetic cartridge installed. The amplifier, the DA-U200, is an integrated design rated at 25 watts per channel with a maximum of 0.5 percent harmonic or intermodulation distortion. The DA-F200 AM/FM stereo tuner has a usable sensitivity of 2.5 microvolts and a signal-to-noise ratio of 75 dB in mono, 70 dB in stereo. The SS-200 speaker systems are two-way air-suspension designs (8-inch woofer, 2-inch cone tweeter) with rosewood-finish cabinets. The cost of this complete ensemble, including equipment cabinet, is $670.
For an additional $220 a two-head cassette machine incorporating Dolby B-type noise reduction can be added to the above. Other options include a 50-watt-per-channel integrated amplifier, the DA-U300, and the SS-300 speaker systems, similar in configuration to the SS-200's but adding an 8-inch passive radiator and providing a 20-watt increase in power-handling ability. The complete system with these two options (excluding the cassette deck) is priced at approximately $750.
The "new” Advent loudspeaker is the successor to the company's original speaker system. It remains a two-way, 8-ohm air-suspension design with a woofer of nominal 12-inch diameter and a 1.25-inch tweeter. however, both drivers are said to have been redesigned for more efficient manufacture, and the output capability of the tweeter has been increased, leading to an augmentation of the system's extreme high-frequency response.
Minimum power required is 15 watts. According to Advent, this change has been made to "take advantage of such recent improvements in source material as the wide use of noise-reduction systems; the higher levels of high-frequency information on records due to improved disc cutters; and a new generation of phono cartridges capable of tracking those higher levels with low distortion." In other respects, the new speaker's performance remains similar to that of the original.
The enclosure, available in walnut finish or a vinyl-clad "Utility" version, measures 26 x 14 1/8 x 11 1/2 inches. Prices: $149 in walnut; $129, utility.

Vintage magazine ADs:
No components have ever been so extravagantly engineered. And so extravagantly praised.
What they said.
Stereo Review: "We see the Accuphase line as occupying a place in audio analogous to that of Rolls Royce among automobiles: Hi Fi News and Record Review: "There is no doubt that the P-300 is one of the most advanced power amplifiers on the world hi-fi market today." Why they said it.
Accuphase components are handcrafted with unprecedented devotion to excellence. Only aero space quality component parts are used, with each hand-selected.
The P-300 amp has modular construction, push-pull complimentary symmetry in all input and output circuits; 3 meter ranges and power-limiting switches to protect your speakers. And more.
With its design overkill, the Accuphase amp can loaf through the most demanding and complex musical passages, maintaining delicacy and precision without sacrificing power.
The C-200 Preamplifier has 10 back and front inputs, 7 outputs, 28 controls-versatility beyond belief-yet is extremely simple in operation.
The reason for such lavish craftsmanship in every Accuphase component is very simple: a deep devotion to music.

Un-identical twins
A-170S ---We couldn't leave well enough alone. So when the A-170 was rated a "best buy" we made it even better. Now it's the A-170S.
It's easy to understand what makes it a best buy; if it were our only deck, the A-170S would cost much more. In stead, we were able to take advantage of the same technology and computerized equipment we use in making decks that cost three times as much as the A-170S.
Which means the difference between our lowest priced deck and our heavy duty decks is features, and not tolerances.
And speaking of heavy duty, the A-170S even has a built-in Dolby* noise reduction system, to virtually eliminate annoying tape hiss.
So if you're looking for a best buy in a top-loading deck for less than S200, your choice is simple; TEAC A-170S.

Now the world's finest tonearm starts at less than $135.
Complete with drive system.
Introducing Dual's three new fully automatic turntables.
You don't have to wait till someday to play your records with the world's finest tonearm. A gimbal mounted Dual tonearm. You can afford one right now.
We have designed into our lowest-priced turntable, the new 1237, the very same tonearm (and drive system) formerly available only on our highest-priced models.
Advantages of the four-point gimbal suspension.
If you're not familiar with the gimbal, it's understandable. Few other tonearms, at any price, have one despite its widely acknowledged superiority.
A true four-point gimbal centers, balances and pivots the tonearm mass at the precise intersection of the vertical and horizontal axes. The tonearm maintains the perfect balance in all planes essential for optimum tracking.
The Dual gimbal employs identical pairs of tempered and finely-honed needle-point bearings, each set in miniature ball-bearings. During assembly, each gimbal is individually tested and adjusted to assure that bearing friction will be no more than 0.008 gram vertically and 0.016 gram horizontally. (If there were a cartridge that could track at forces as low as 0.25 gram, this tonearm would do full justice to it.) Further, the straight-line tubular design (for maximum rigidity and lowest mass) and the settings for zero balance, tracking force and anti-skating are, like the gimbal, identical in every Dual tonearm. The tone arm establishes and maintains the correct cartridge-to-groove geometry, and allows the stylus to trace the groove contours freely, precisely and with the lowest practical force. In short, flawless tracking.
Advantages of the Vario-belt drive system.
Another important inheritance is the Vario-belt drive system. This drive system comprises a high-torque synchronous motor, a precision-machined Vario Dual pulley, a precision-ground belt and a machine balanced, die-cast platter. The Vario-pulley simply expands and contracts for reliable fine-speed adjustments. There are no complicated mechanics or electronic circuitry, which add nothing but cost.
Versatility and reliability too.
We've just described the qualities of the new Dual fully automatic line that will make your records sound better and last longer. But there's more. For versatility, you have fully automatic and manual start and stop, plus provision for multiple play. And cue-control damped in both directions. Plus pitch-control, rotating single-play spindle and multi-scale anti-skating.
Everything we've described applies to the 1237, which is, incredibly enough, our lowest-priced model.
And where the 1237 ends, the 1241 and 1245 begin.
With an even higher degree of performance. And very handsome, contemporary, low-profile bases.
One further point. All Dual turntables are ruggedly built. They need not be babied, by you or anyone else in your family. As any Dual owner can tell you, they are designed to last for years and years and years.
Now we suggest that you visit your favorite audio dealer and see first hand what Dual engineering is all about. You may then wonder why no other manufacturer puts so much care and precision into a turntable.
The answer is simply this. For more than seventy-five years, craftsmanship of the very highest order has been a way of life with the Dual people in the Black Forest. As nowhere else in the entire world.
Dual 1237: less than $135; base and cover less than $30 additional.
Dual 1241: less than $200, including deluxe base and cover.
Dual 1245: less than $230, including deluxe base and cover.
Other Duals to $400. Actual resale prices are determined by and at the sole discretion of authorized Dual dealers.

Setton front access turntable: 8 unique features for a world premiere.
The TS-11 is a true rarity.
Because, even for the ever-changing world of high fidelity, it represents total innovation : front access for professional-standard turntables. Without doubt, the TS-11 will become the most-imitated development in the history of hi-fi.
Conceived by the Research Division of Setton Engineering, the TS-11 does away with several outdated traditions associated with nearly all turntables in existence today.
1- Setton cuts out wasted space above and behind the turntable by the introduction of Slide-O-Magic horizontally sliding. Their feather-light sliding and closing action can not disturb tonearm tracking.
2- These dust-covers are open at the front, allowing precision, accident-free manipulation of the tonearm at all times.
3- Thus Setton can offer the option of lifting the entire component and placing it where many felt it has always belonged : near or actually at eye level in a rack or shelf position.
4- Frontal configuration of the controls, for optimal handling, especially in conjunction with other components.
5- Vertical-action controls.
It is a fact that a vertical movement induces less vibrations than an horizontal one since it exerts pressure toward a perfectly rigid surface.
6- Illuminated instant read-out panel to check speed and functioning; when recording, it makes it possible to ascertain at a glance that a record is finished.
7- Totally unique lighting t let you choose exactly the cut you want to hear, even in the ful darkness of your shelf.
8- New designed wide insulating base pads.
The extraordinarily slim by houses a self-cooling motor, driving a precision cast-aluminum alloy platter to full speed in less than three-eighths of a revolution. Precision belt-drive is the reason for the astoundingly low 0.08 % average wow and flutter, with practically nonexistent audible rumble particularly important figures when taping is involved.
Vertical and horizontal friction is a mere 0.001 gram, and the stylus force gauge and anti-skating settings are calibrated, allowing for an accuracy as perfect as can be measured.
This unit was designed, aesthetically and technically, to frankly appeal to only the most exacting and perceptive buyer: Setton Engineering went to extreme lengths in the conception, development and testing of this project. The Setton standard of solidity, too, will become a legend in its time.
Each TS-11 is heat-tested for eight hours and every circuit, every moving or non-moving part exhaustively.
Function-tested for 90 minutes, details of which are confirmed on the Quality Control card accompanying each component.
Likewise, the TS-11 carries a two-year comprehensive guarantee.
Clearly, such exigencies dictate limited supply and prices somewhat above average. The only way t appreciate the front-access TS-11 is to test it for yourself at your Setton dealer.
We are confident that you will find it a singularly profound experience.

THIS IS WHERE TOMORROW'S GREAT MUSIC IS COMING FROM.
We think musical styles change because musical talents change.
There is hardly a musician making money today who doesn't know as much about recording music as he does about playing it. And recordists know as much about playing music as they do about recording it.
Because both know the equipment that captures music can also be used to improve it.
So while musical styles may change, the interdependence of musician, recordist, and the instruments they use will not.
And that is the reason for the TASCAM Series by TEAC.
For not very much money TASCAM lets both musician and recordist get their hands on mixers and recorder/ reproducers that let both tailor their music their way.

For every kind of music, for every kind of need, at home and on the road, by price and application, everything we make has the same goal as everything you make--be the best..
Because it still takes great talent to make great music.
