DUAL 1010 A

Auto/Standard Turntable for single play and changer operation.

The ingenious design of the top/mounting spring screws makes it possible for you to mount and secure the Dual 1010 to its base - or to the cutout mounting board of a console -  entirely from the top. No need to fumble underneath, nor to take anything apart.

The Dual 10101 tonearm is designed for tracking at the low stylus forces required by high compliance cartridges. Once adjusted for your cartridge, the force will remain highly linear for a complete stack of records. Stsylus force is adjusted by turning the knob located at the pivot; clockwise to increase force, counterclockwise to reduce force. The range of adjustment is from 2 to 7 grams, with clock stops at 1/2 gram increments.

The tonearm has been set to descend accurately into the lead-in groove. But if the dimensions of your cartridge and/or the location of its stylus cause the lattere to touch the record either too far in or too far out, it can be adjusted quite easily.

All the operations of the Dual 1010 are activated by smoothly acting slide switches. Unlike push buttons, they do not jar the spring-mounted chassis or induce even momentary vibration. Thus the three spring-mounted footings of the Dual can enjoy a softer, more shock-absorbent characteristic, rather than a compromised stiffness.

DUAL 1010 F

 DUAL 1010 F 

The Dual 1010 F in all the functions is similar like model 1010 A, but  in addition is equipped in function of variable speed control.

Pitch Control - each of the 3 standard records speeds (33-1/3, 45 and 78 rpm) may be varied up to 6% by means of pitch control. The selected speed may be checked using the stroboscopic disc supplied with the unit.

How to use?

Place the stroboscopic disc on the rotating platter. Under AG illumination, the circular line patern for the desired speed will appear stationary - while the record is turning - when the actual platter speed matches the desired speed. The pitch control knob serves for making the exact adjustment.

Also the 1010F is equipped with Dual Stereo crystal cartridge CDS 630, duplo sapphire needle.

BSR UA 70

 The BSR UA70 record changers will play a stack of one to six records in automatic sequence and shut off after playing the last record. 16, 33-1/3, 45 and 78 RPM records can be played.

Indexing, correct tone arm set-down, for playing 12", 10" or 7" records is determinated by the position of the 12, 10, 7 control.

The tripping method is the velocity type. Rapid tone arm acceleration is required to actuate the trip mechanism.

The changer operates on 117 V AC, 60 Hz with provisions made for converting to 220 V AC operation and 50 Hz operation. The motor leads can be connected as shown in diagram, on the motor, for operation on 220 V AC.  A simple conversion kit for changing to 50 Hz operation is available.

Dynaudio Confidence 3

As great truths are wont to do, the Confidence 3 is discrete about its qualities. We all know of much, much bigger loudspeakers 49.5 x 22.5 x 33.5 cm won't even impress a dwarf in very flat shoes - one of the reasons why the Confidence 3 has its personal dedicated stand). Or speakers with even more wallop (die-hard heavy metal fans will probably put on an aloof smile - at least until you turn the volume knob a little clockwise).But if true musical worth is what you're after, the Confidence 3 is in a class of its own. The tweeter is a special version of our justly famous Esotar T-330 D, which combines absolute brilliance with ultimate musicality - without the least bit of hardness. (You probably knew how it looks without realising it: the most reputed speakers in the world tend to be designed around this tweeter, a laudable step in the right direction.) With its ferrofluid-damped resonance and an aluminium voice coil which is lighter than a feather, it is not only at the outer frontier of the technologically feasible. It also puts an end to all diffuseness and tonal colouration.

Not in the least because the backwards-radiated energy of the Esotar (a democratic 50%), thanks to damping measures calculated by our famously reliable Danish engineers on high speed computers, is almost completely absorbed.

Which makes the Confidence 3 one of the few speakers that do not distract you with their own echo.

Meridian 207 Pro

 No ordinary Compact Disc Player

Meridian have earned their reputation as the leading designers of the world's finest sounding Campact Disc players. The 207-Pro is designed and made by these enthusiasts in England, and extensive research has been made in the evolution of this very advanced CD player. Every detail of the mechanical and electric engineering, from the floating cast subchassis to the electronic volume and comprehensive remote controls, is designed to make the 207-pro the finest Compact Dsic player. The Meridian 207-Pro est quality music playing system for your home - and it combines this formidable performance with effortless, yet comprehensive control of its functions. It has no equal.

A powerful feature of the Meridian 207-pro is the built-in preamplifier facilities. It can connect a tuner and tape directly to Meridian active loudspeakers, to give a simple system with the finest combination of performance and control available; or it may be used in a conventional music system.

This leaflet highlights some of the design features of the Meridian 207-pro, but only a visit to a Meridian dealer will convey a true impression of its distinctive quality.

 Meridian 207-Pro, why separate boxes?

It is no accident that the 207-Pro is arranged in two parts. One contains the precision-engineered motrised CD transport system and the system power supplies. The CD transport carries the single-beam laser pick-up assembly in a sprung die-cast subchassis, and runs on precision stainless steel guides. The assembly moves out at the touch of a switch on the front panel. This whole mechanism is housed in a heavy aluminium tube and when the plate-glass door slides shut against its soft surround, the spinning Compact Disc is acoustically and mechanically isolated. This aspect of the construction adds a lot to the sound quality of the player and yields the convenience of front-loading without the loss of quality that normally results. The digital signal is passed via a single cable to the electronics unit.

 The 207 provides a unique conbination of quality and facility. The very highest standards of audio performance are combined witha truly comprehensive control system, resulting in a product which has received worldwide acclaim. Meridian now provide a complementary range of products to the 207 including 201 Preamplifier,, 205 Power Amplifier, 204 Tuner Timer, 209 remote Control and a range of 3 Active Loudspeaker Systems.

The 207 has the following new features:

New Meridian designed servo circuits for improved playability.

2 box construction which provides acoustic and electronic isolation of circuits.

High mass 3 point sorbothane suspension system for better sound.

New Meridian designed microprocessor control functions for simpler operation.

Inputs for radio, tape and LP record deck with switchable cartridge level matching

High energy power supplies for better control of audio circuits resulting in improved sound.

Full function remote control system.

SANSUI LM-330

SANSUI LM-110

Sansui AU-X301

Sansui AU-X301 Integrated Amplifier

Built to drive low-impedance loads

Today's speaker system present lower impedances to the amplifier than ever before; nominal impedances of 6 or less are becoming more and more common.  And when playing music with wide dynamic  undulations, the actual impedance may go still lower, taxing the amplifier heavily. this is especially true with digital programs because of their wide dynamic range and fast transient response.

That's why an amplifier should have the capability to supply as much current to the power transistors as demanded, and at an instant's notice. Otherwise, gross distortion can result, making it impossible for you to enjoy the full benefits of digital sound. The AU-X301 is expressly designed to drive low-impedances; its dynamic power ratings tell the story - 110 watts at 8 ohms; 190 watts at 4 ohms, and 260 watts at 2 ohms.

High-power output transistors and high-capacity power supply.

Supporting the admirable low-impedance driving capability of the AU-X301 are two factors; high-power output transistors, and a well-regulated power supply that combines a high-capacity power transformer and two large electrolytic capacitors.

High-quality phono equalizer for MM and MC cartridges.

The AU-X301 accepts an input from any cartridge of any impedance. With MC cartridges, you can choose the impedance that your cartridge requires. No sonic degradation results from impedance mismatching.

Luxman L-81

Solid State Intergrated Amplifier

A tremendous amount of time and energy was spent to achieve excellent tonal quality through unique and innovative circuit design. That combined with sophisicated styling makes these units beautiful to the ear and eye.

The power amplifier section is a whole-stage direct-coupled OCL system and the output stage is pure complementary. The differential amplifier circuit is composed of 2 stages to ensure DC stability throughout the entire power amplifier section.

Selected transistors are used especially at the 1st differential stage which have high treble cut-off frequency and large collector output capacity. At the same time, the pre-driver stage is driven by constant current so that crossover distortion triggered by class "B" operation of the output stage is suppressed. This is a technical feature common to all current Luc amplifiers as crossover distortion could impair sound quality and should be minimized.

An important feature of the pre-amplifier section is the equalizer circuit wherein the same basic circuit as the C-1000 control center is used. The operation amplifier is composed of a special IC which inherently has high loop gain and the closest frequency to that of the RIAA equalizer,, which ensures unconditional stability and overall improvement of various characteristics such as distortion, etc, throughout the entire bandwidth with sufficient amount of negative feedback.

The buffer amplifiers incorporate an orthodox 2-stage direct-coupled circuit and also LUX's well known NF (Negative Feedback) type potentiometers for the tone controls. The turn-over (roll-off) frequency for tone control is interchangeable in 2 steps with a useful "defeat" position.

We know the true measurements of minimum performance standards of a quality amplifier must be of a very high level. However, these figures are not the only requirements.

Despite every effort to make amplifier design a pure science one amplifier among many with similar absolute specification can still have, relatively, far better sound quality.

The reson there are more comprehensive theories of amplifier design which account for such problems as harmonic intermodulation, and notch distortion, stbility, filters, and equalization as they relate to statements of power.

Whatever the scientific theory, Lux conducts the most detailed listening test with engineers and musicians in different fields from what is considered good in article.

The Lux sound is not only a science but an art.

Luxman R-1030

 Model R-1030 Am/FM  Stereo Receiver

A new receiver from Lux with optimum cost/performance ratio. An exhaustive review of current circuitry and functions in receivers has made it possible to achieve greater simplicity whilsst still retaining the features indispensable to real High Fidelity. Power output 30W/channel into 8 ohms both channels driven with 0,05% total harmonic distortion.

Pre-Amp Section

Sound playback is possible from any of the FM, MW, Phono and Auxiliary terminals. A 2-stage direct coupled amp in the equalizer circuitry with PNP and NPN transistors gives good linearity and high input voltage at phono. Versatile contouring of the reproduced sound is possible with Lux's exclusive NF type tone control for bass and treble. High- and low-cut filters are useful to renmove tape-hiss disc noise and turntable rumble. A loudness control offers effective tonal compensation at low-level listening.

Main Amp Section

The direct coupled DC output configuration ensures the best possible bass and transient response and gives the amplifier excellent characteristics throughout. Today's almost mandatory full complementary symmetric output attains the least possible distortion, i.e.0,05% up to 30 W both channels driven into 8 ohms.

 FM Section

The front-end features a high grade 3-gang tuning capacitor to provide a satisfactory sensitivity at 2 µV, and 2 pairs of linear phase ceramic filter ensures good bandpass response. The superb figures provided by the PLL MPX IC in respect of distortion, separation and Signal-to-Noise will remain constant over a long period of time.

AM Section

A newly developed IC for AM reception makes it possible to obtain high sensitivity, low distortion and strong AGC, and the adoption of a ceramic filter of good selectivity ensures clean AM broad casting without interference, thus most AM stations become far more "listenable".

Pioneer SX-434

Stereo Receiver with high-performance tuner and direct-coupled OCL power amplifier.

There is a wide range of Pioneer stereo receivers to satisfy the needs and demands of virtually every audio fan. One of the latest, the SX-434, is specifically designed for those who insist on low distortion but who feel that paying for power they don't need is wasteful. The SX-434 has more than enough power, yet is priced to appeal to budget-conscious music lovers. Its FM section provides an excellent 1,9 µV sensitivity (IHF), a capture ratio of 1,0 dB (IHF) selectivity of 60 dB (IHF), and superb stereo separation of more than 30 dB over a 50 to 10,000 Hz range. Advanced electronic circuitry throughout includes a low-noise FET and a frequency-linear 3-gang variable capacitor in the FM front end, exclusive IC and phase-linear ceramic filters in the FM IF section and more. The phono equalizer in the SX-434 is high-fidelity all the way, with RIAA equalization of less than ±1 dB deviation. The power amplifier circuitry is the pure complementary direct-coupled OCL type with wide response and power bandwidth. The SX-434 produces 15 W + 15 W continuous RMS power (both channels driven at 8 Ω) with harmonic distrotion of less than 0,8% over 40 to 20,000 Hz bandwidth. This is enough to drive two pairs of stereo speaker systems individually or simultaneously.

The Pioneer SX-434 features top-class FM capabilities. The low-noise FET and frequency linear 3-gang variable capacitor in the FM front end contribute to the excellent sensitivity of 1,9 µV (IHF). Improved image and spurious rejection characteristics and a high signal-t-noise ratio in performance.

FM IF Section with IC and Ceramic Filters

State-of -the -art. Techniques are also employed in the FM IF amplifier of the SX-434. phase-linear caermic filters and an advanced IC afford a high selectivity of 60 dB (IHF) and a capture ratio of 1,0 dB (IHF), figures you'd expect from a tuner or receiver in a higher price category.

FM Muting Switch

Annoying inter-station noise can be cancelled during tuning by the handy FM muting switch.

Exclusive IC-Equipped AM Section

Maximum fidelity and noise-free listening can be enjoyed in the AM band with the IC-equipped AM section of exclusive Pioneer design.

RMS Continuous Power 15 x 2

The pure-complementary direct-coupled OCL design of the power amplifier section in the SX-434 assures wide frequency response wide power bandwidth and satisfactorily low distrotion. Continuous RMS power over the 40 to 20,000 Hz frequency bandwidth (measured with both channel driven into 8 ohms loads) is a stable 15 W + 15 W with less than 0,8% harmonic distortion.

Two-pair Stereo Speaker Facilities

With its ample power provisions, the SX-434 drives up to two independent pairs of stereo speaker systems, one pair at atime or both together. Ideal for powering those remote speaker.

Precise RIAA Equalization

The two-stage direct-coupled NF (Negative Feedback) design of the phono equalizer in the SX-434 enables audio reproduction of records within ±1 dB deviation from the RIAA characteristic curve.

Click-Stop Tone Controls

The bass and Treble tone controls are the click-stop type for convenience in adjustment.

Other Features

The control capabilities of the SX-434 are ideal for the average hi-fi set-up; it handles a turntable, tape deck, microphone, Aux and has an output jack for stereo headphone. The provided loudness contour switch enhances frequency response at low-volume levels.
