Rare paire Luxman C300 et M300:Amplificateur et préamplificateur (avec phono). État : "Occasion" En excellent état de fonctionnement, notez qu' il faudra remplacer une ampoule du voyant Led  "classe A". Voltage 220V. Les deux appareils sont visibles chez Jefferson Hifi à Pérouse où je les ai déposés. Livraison possible en France, en Europe,etc nous consulter pour les frais d'envoi internationaux. Le M300 a été produit en même temps que la série C300. Je crois qu’il n’en a été produit que 2000 dans le monde. C’est non seulement une paire de collection, mais le haut de gamme des luxman des années 1980. Ils sont les dernières combinaisons pré/ampli, à avoir été fabriquées sans implication de Alpine(qui a ensuite  modifié sérieusement la qualité Luxman  hélas.). ils ont été primés "produit de l'année" au début des années 80.  Le M300 se laisse utiliser soit en classe A, où il développe 2x42 w sous 8 ohms en classe A, ou alors 172w en classe AB sous 8 ohms. Comme toujours chez Luxman, on peut espérer une dizainede watts supplémentaires dans chaque modes, vu qu'ils utilisent unsystème de mesure très strict sur leurs fiches techniques. Il faut surtout savoir qu’il ne faut basculer de classe AB en classe A que à l’arrêt, en redémarrage à froid.  Voici  les caractéristiques techniques (https://audio-database.com/LUXMANALPINE-LUXMAN/amp/m-300-e.html) et https://audio-database.com/LUXMANALPINE-LUXMAN/amp/c-300-e.html 1)Préampli C300: Frequency response: 0.5Hz to 140kHz   Total harmonic distortion: 0.005% Input sensitivity: 0.09mV (MC), 2mV (MM), 140mV (line)      Signal to noise ratio: 80dB (MM), 100dB (line) Output: 140mV (line), 1V (Pre out), 20V (Pre out Max)  Dimensions: 478 x 163 x 384mm     Weight: 9kg 2)amplificateur M300 Form Duo beta plusX poweramplifier Succession effectiveoutput (20Hz - 20kHz, both channel simultaneous operation) Class-A: 40W+40W (8ohms) AB class: 270W+270W (4ohms) 170W+170W (8ohms) THD (8 ohms) 20Hz- 20kHz-3dB Class-A: 0.005% or less AB class: 0.005% or less Cross modulationdistortion (8 ohms) 60Hz: 7kHz=4:1, -3dB Class-A: 0.005% or less AB class: 0.005% or less Output bandwidth Class-A: 10Hz-100kH-3dB(0.015% of distortion) AB class: 10Hz - -100kHz three dB(0.04% of distortion) Frequency characteristic 10hz-100kHz-1dB (aClass-A and AB class) Input sensitivity Class-A: 0.45V ABclass: 1V Input impedance 50kohm (a Class-A and ABclass) SN ratio (IHF-Acorrection) Class-A: 115dB ABclass: 120dB Remains noise (IHF-Acorrection) 30 microvolts (a Class-Aand AB class) Dumping factor 120 (1kHz, 8 ohms, aClass-A, and AB class) Protection network DC drift detectionspeaker protection network Overcurrent detection amplifierprotection network Attachment Circuit operationswitchpoint (indicator) Peek indicator Inputattenuator Headset jack Speaker-off switchpoint(indicator) Line phase sensor Supply voltage AC100V, 50Hz/60Hz Power consumption (Electrical Appliance and Material Control Law) Class-A: 420W ABclass: 430W Dimensions Width 478x height 214xdepth of 484mm Weight 30kg Stereo power amplifier which adopted the Duo beta plusX circuitry. In order to control NFB of an amplifier circuitry appropriately, the Duo beta circuitry was developed and it is adopted as M-300. After this makes amplifier to the extent that it is used also from a nakedness property as it was, it adds proper-quantity NFB and DC servo as finish of a tone quality, and is suppressing the transitional distortion of a supression of play sound, TIM, etc. by superfluous NFB etc. Furthermore, in M-300, the thought of a suitable control is introduced also into a power circuit, and it is considered as the power-source Duo beta plusX. At plusX, the stability of a comfortable tone quality and an operation is reconciled because the bottom gives controlling force calmly on the assumption that a generous power-source part. M-300 can change and use a Class-A and AB class. The Class-A operation has a structure which amplifies a signal wave form as it is. Therefore, it becomes unrelated to switching distortion or crossover distortion, and does not have the cause that it is distorted in addition to an element's own linearity. In M-300, the Class-A operation excellent in adopting a Duo beta as LAPT which excelled [element] in the high region property, and an amplifier circuitry, and adopting plusX as a power circuit is realized. In AB class, Oide power which drives transitional distortion below into a limit of measurement in pursuit of a nakedness property also in an operation, and is not made in a Class-A operation on it is realized. At the time of a switching of a Class-A / AB class, in a performance, sound does not break off and a noise is not generated, either. Circuitry constituted all the amplification stages from a push-pull circuit from the input stage to the output stage, and the amplifier which was excellent in the nakedness property which will be the requisite for a Duo beta circuitry is realized. The pre-driver stage is making the input stage the transistor which was excellent in the high region property with the cascode interconnection with the stream composition of the cascode bootstrap and the differential push pull by complimentary FET of a Pch type and a Nch type. And the driver stage and the power stage are considered as the push pull stream composition by a three-step Darlington connection. A linearity makes an output element high speed power transistor linear arithmetic processor-T which was well excellent in the high region property with a triple push pull stream composition, and the electric current is sent. In this way, the static characteristics and the dynamic behavior improved. And proper-quantity NFB and DC servo are added. The power-source part had the twin monophonic stream composition of right-and-left full independence, and has acquired the merit of a linearity covering all the bands, and the outstanding crosstalk property. The power transformer is performing and using the coil mandatory adopted and put into practice among the object for Rch, and two Lch. First, the power stage and the drive stage were made into another coil, and also the primary side and secondary side has unified the orientation of a coil. This is because it is checking having influence on play sound with the potential (polarity) which a transformer begins to roll, rolls and the last each has between opposite groundings. Moreover, four right and left adopt the type only with a capacity of 12,000 micro F for an audio as a filter capacitor, and low-impedance-ization of the power-source part is attained to it. In order to cope with the rush current which becomes large as the capacity of a power-source part becomes large, the rushes current preventing circuitry is adopted. The speaker protection network and the amplifier protection network are carried. The internal organs of the speaker protection network which detects DC output in an output-terminal and separates an output are carried out. Furthermore, when the speaker code etc. short-circuits, even if there is a big input, an amplifier circuitry is protected or the electric-current preventing circuitry is carried. After the elements currently used examine, it is using it, carrying out a tone-quality mandatory strictly uniquely. The film capacitor generally called non-polar is also arranging a polarity etc., and the capacitor is carrying out the tone-quality mandatory strictly. Moreover, the precision succession good transformation Detent volume excellent in the tone quality and a feeling of an operation is adopted as input attenuator. Furthermore, in terminals, the small gilding pin jack of contact resistance was adopted as the input terminal, and the large-sized screw type is adopted as a speaker termination. The product line was packed into the shortest distance, and also it has chosen high materials of the tone-quality effect, such as a shielded cable of oxygen free high conductivity copper and 500 core. Moreover, in order to suppress an elevation of the source impedance of the pattern side of a substrate, the power bus by a copper plate was adopted and the performance of a power source is employed efficiently. The line phase sensor is carried, by the functionality which detects this polarity, the polarity of the equipment was unified and the tone quality is improved. The indicator turned on at the clipping point of an output is carried, and a peek can be supervised.

BeoLab 6000 represents both the engineering skills as well as the design capabilities from Bang & Olufsen.  BeoLab 6000 is probably one of the most famous speakers around today being a part of the standard exhibition at the Museum of Modern Art in New York.  A great advantage with the BeoLab 6000 is the fact that it has two PowerLink connections giving the possibility to loop-through the signal to the second speaker directly.  Features: BeoLab 6000 fills the room with sound The choice is simple - you can fill your home with big black boxes, or you can make a stand with BeoLab 6000 and fill it with beautiful sound and beautiful looks. Aluminium Formed from a single piece of aluminium, BeoLab 6000 is shaped to stand out from its surroundings, but coloured to match any Bang & Olufsen audio or video setup. Active loudspeaker benefits How does B&O reduce the overall size of a loudspeaker, but improve its sound performance? It can only be done by placing the amplifiers directly into the loudspeaker cabinet. It's called 'Active Loudspeaker Technology' and is used to combine the purest of sounds with the smallest and simplest of shapes. Fits any room With a height of just 110cm and a depth of 10cm, finding space for a pair of BeoLab 6000 speakers is never going to be a problem. Its superior sound capabilities ensure that its performance will never dictate your placement options. The polished aluminium cabinet is available in a range of colours - black, blue, green, red and natural - that will match any Bang & Olufsen audio or video setup. Materials and finish The deliberate choice of material, and the final surface treatment of the products’ finish, are characteristic of Bang & Olufsen and one of their true core competences. B&O's designers know that people use several of their senses in experiencing a product. They therefore derive great pleasure from tactile experiences, whether they are touching a cold or a warm surface, or one that is smooth or textured. The span of materials used for Bang & Olufsen products is wider than that of any other company within the trade, and they are carefully selected for their high quality and their ability to fit naturally into a home environment. The finish is then refined to perfection and created to provide a tangible experience that supports the visual impression. Why build amplifiers into the loudspeakers instead of keeping them separate? Because you can reduce the size of the cabinet volume to one-third of the size of a conventional loudspeaker with the same sound capacity. The principle is called Active Loudspeakers, and what you get is a compact loudspeaker that can play at high volume without distortion or damage to its drive units. Furthermore, when amplifier, treble and bass units are paired for the same task, they can be tailored to compensate for each other's shortcomings. What you hear is music that sounds exactly like the instrument it originally came from (See active speakers) Deep bass: how to make deep bass with a shallow cabinet All loudspeakers, regardless of brand, size or construction, make sound by converting electric energy into acoustic energy. They push air in waves, which is what our ears pick up. To get high sound pressure, you need to move a lot of air. You can use a very large diameter loudspeaker membrane, which moves a very short distance. Or (as Bang & Olufsen prefer), you can make the membrane "deeper", in other words, make it move a greater distance with a smaller diameter. Imagine two balloons, one round and shaped like a ball, the other long and tubular. Both contain the same amount of air; it's simply their shapes that are different. A side benefit to the deeper membrane is that it allows a smaller cabinet, with greater freedom as far as form and function are concerned. Since no two loudspeaker units have exactly the same physical characteristics, Bang & Olufsen calibrate them individually to make certain that the sound of each and every loudspeaker leaving our factory is identical. By employing an active electronic crossover network with equalization, we're able to adjust frequencies before they're amplified. The signal from the sound source is shaped before distribution to the separate power amplifiers for bass and treble. In this way, the performance of the various components is "fine-tuned", until they produce an ideal, harmonised output, which will be the same, no matter which BeoLab loudspeaker you feast your eyes upon. The custom made driver units of a BeoLab loudspeaker feature extra-heavy membranes with longer movement, which help produce a deeper bass. Adaptive Bass Linearisation Adaptive Bass Linearisation (ABL) is a process patented by B&O and is incorporated in BeoLab loudspeakers. The idea is to use the surplus capacity in amplifiers and driver units, arising by normal listening levels, for a bass extension - a sound reproduction with more bass, than the loudspeaker otherwise would be able to produce. The function is adaptive. This means that the loudspeaker adapts to the signal it receives. Loudspeaker drivers are therefore fully exploited, without suffering mechanical or electronic abuse, and the built in amplifiers are not subjected to signals would otherwise create an overload situation. ABL  gives stunning bass reproduction considering the size of the loudspeaker in which it is incorporated, under normal listening levels. BeoLab 6000: active loudspeaker, 2 power amplifier modules, adaptive bass linearisation and aluminium cabinet.

Une platine réellement AUDIOPHILE !!! et si CLASSE, si BELLE,....   A UTILISER QUOTIDIENNEMENT OU COLLECTIONNER WORLWIDE DELIVERY Will be sent in safe package Sera livré en colis protégé BEST REGARDS, The three-speed Dual CS 5000 is a semi-automatic turntable that starts rotating when the arm is moved from its rest and stops when the arm is returned. At the end of a record's side (which is sensed optically), the arm lifts and returns to its rest and the motor shuts off. The platter, which weighs 3-3/4 pounds including its thick rubber mat, is belt-driven from a tiny, flat, disc-shaped motor. The motor's speed is electronically controlled by a quartz-crystal reference oscillator and a microprocessor. In addition, a second control loop measures the platter's speed with an optical sensor and corrects the motor speed as required to maintain the correct playing speed. Unlike almost all other currently available record players, the Dual CS 5000 operates at 78 rpm as well as 33% and 45 rpm. The tonearm of the CS 5000 is designed to minimize many of the recognized weaknesses of typical pivoted tonearms. It is supported by gimbal pivots for both axes of motion and operates at all times in a fully balanced state (the downward tracking force is supplied by a coiled spring). Dual points out that the arm-support system eliminates any need for critical leveling of the turntable, which can in theory be operated at almost any angle to the horizontal. Another potential problem, warp wow, is a common result of playing a warped record with a tonearm whose vertical pivot is located above the record's plane. The combination causes a periodic fore-to-aft shift of the stylus as the arm travels over the warp and superimposes a frequency modulation (wow) on the program. The Dual CS 5000's tonearm has its vertical pivot in the plane of the record, which reduces warp wow to its lowest possible level. The slim, tubular-aluminum tonearm has a removeable head-shell featuring Dual's adjustable vertical tracking angle (VTA). The cartridge can be tilted by a knob on top of the shell, varying the VTA over a ± 5-degree range. A critical listener can do this by ear, and Dual also recommends VTA settings for a number of popular cartridges. The tracking-force and antiskating controls are on the tonearm's pivot structure, near the arm rest and cueing-lift lever. Most turntables, including the CS 5000, have platters that are designed to concentrate their mass around the outer edge, where it contributes the most to the inertia of the system. These platters resemble a shallow bell, and they usually ring like one when struck or otherwise excited mechanically, a characteristic that can color or muddy the reproduced sound. The platter of the CS 5000 features a unique damping system to eliminate such resonance. Inside the outer rim of the cast aluminum-alloy platter is a heavy metal ring covered by a plastic hose that acoustically couples it to the platter an

Tuner Denon TU 701 in very good condition. This unit was sold about 64000 yens in 1977 (600 dollars). It is an exceptional tuner, one of the best ever produced. FM stereo tuner in which the drum type long scale dial plate was carried. In addition to a frequency linear 5-unit variable condenser and one step of RF, MOS FET which was excellent in the noise characteristic is adopted as a front end part. An eight linear phase ceramics filter and LC circuit are adopted as an intermediate frequency amplifier, and the degree of selection is improved to it. Moreover, the improvement of a stereo distortion is also aimed at by adoption of a broadband ratio detection circuit or a phase compensation circuit. Furthermore, sound quality degradation by interference is prevented with the high gain magnification and the seven-step limiter using high accumulation IC. An intermediate frequency magnification circuit for exclusive use is prepared for sub functions, such as a perpendicular multipass terminal, muting, signal meter, and the influence by these circuits is avoided. A large-sized level meter is formed in right and left of the front panel, and the right meter is made signal meter for the left meter with the level meter of multipass meter combination. In the right meter, not only a tuner Output voltage but measurement of external audio voltage, such as a power amplifier output, is possible.

Hello, I am selling my Gimball, only used a couple of times for sport videos recording. Will come in the original box and the invoice. Details below: ACR The Plus is a device capable of stabilising small digital cameras and DSLRs. The stabilisers job is to make sure that the horison level is perfectly kept where it should be even during the most insane shot – it also negates unwanted round movements of the camera. An agile operator experienced in working with Steadicam or similar systems can achieve results not possible before. The versatility of this technology is limited solely by the creativity of users and the gear itself is very easy to configure. Handing over The Plus during a single, continuous shot, changing the shooting action from handheld to UAV, working in normal and inverted modes – these tasks require only a moment of preparation and open completely new horizones to open-minded filmmakers. Give it a try! The stabiliser Thanks to using a twin gyro & accelerometer system the stabilisation itself is sharp and precise while keeping the device simple to use. A powerful processor allowed us to enhance the primal functionality of the stabiliser with a set of new functions: more natural, iconic Follow Mode, larger number of saveable settings profiles, more reliable operation in demanding conditions. Three direct drive brushless motors were created to perfectly control the camera on each of the stabilised axes. The stabiliser was built according to our own solutions and technology. We used the best available materials – aircraft grade duraluminum, carbon fibres. The electronics and motors were developed from scratch to meet the requirements of our most demanding users.   The device Is powered by a single LiIon battery (included in the set) fitted inside a dedicated compartment within the carbon tube. Depending on your gear configuration it can work constantly up to two hours on a single charge. The battery charger is also included. A uniqe feature is the possibility to power up external accessories attached close to your camera straight from the main battery thanks to an auxillary power socket located at the camera shelf. Such accessories include wireless video transmission systems, follow focus systems, etc. ACR The Plus is the upgraded version of the classic BeSteady ONE – the gimble which started our journey. The first units of the predcessor were delivered to the first users around the end of 2013. We would not have made it without the support of hundreds of wonderful people who supported us via the initial KickStarter campaign. Thanks to the invaluable help from many enthusiasts we were able to revaluate, test and complete the upgrade project with success.    The heart of the BeSteady is within the mainboard. Highly modified BaseCam software, developed in direct cooperation with Alexei Moskalenko, enabled us to create a product tailored for your needs. A fast Cortex processor, vast internal memory and twin gyro & accelerometer system allows the device to easily cope with tasks such as fast running, shooting from moving vehicles and working at uncommon and extreme angles and positions. The lack of complicated configuration procedures (the so-called PID tuning) is gone with the introduction of simple, understandable sliders responsible for setting the needed parameters for every axis. The uniqe, very characteristic handheld mode, the Follow Mode, allows the operator to catch smooth scenes during continuous takes thanks to responsive and natural movement control system with a lot of precise math behind it. Moreover, the device can be controled using a dedicated analog Thumbstick or an external remote control device. The stabiliser can work in different modes thanks to the implementation of advanced control & stabilisation algorythms. The basic mode of operation is the Xtended Stabilisation – where the device maintains the exact camera position targ
