Technics SL-P1000 AC120V 50/60Hz. Include: SH-R52 remote control. Paper copy instruction/owners manual and service manual Description: The compact disk player which inherited the technology of SL-P1200, such as a classAA audio circuitry, a vibration-proof design, an edit function, and also introduced new know-hows, such as strengthening of the heavy bass by an active servo power supply, and equipment of a digital output termination. The classAA scheme is adopted as a total of each six L/R of three circuitries, a sample hold circuit, buffer amplifier, and headphone amplifier. The high-resolution is gained according to powerful drive capacity and exact waveform-transmission capacity. With the sample hold circuit which removes the switching noise which a D/A converter generatesIt becomes independent about the voltage control amplifier which performs a waveform transmission, and the electric-current drive amplifier which performs a load-intensity drive of the capacitor for a hold, a low pass filter, etc., and the precision of the D-A conversion is raised by operating voltage control amplifier by an unloaded condition. a digital analog converter -- Lch and Rch -- the dual converter scheme which arranged the converter for exclusive use, respectively is adopted. While this solves the problem of the phase difference of L/R, the converter output was operated in electric-current mode, the D-A conversion was accelerated, and the distortion and resolution in a high region are improved. In order for the noise generated by the digital circuit system or the servo circuitry system to prevent mixing in an audio audio circuitry through a power source, 2 transformer schemes equipped with the transformer of respectively the special purpose of a digital system and an audio system are used for a power transformer. Furthermore, it separated into three lines, Lcn, Rch, and headphone amplifier, and the secondary winding of the transformer only for an audio system has also prevented the cross interference in an audio circuitry. Moreover, while using first recovery diode and the electrolytic capacitor for mass audios for a rectifier circuit and reducing a rectification noise, the powering stabilized also at the time of the Dainyuu power is made possible. In addition, the thing for which the audio circuitry side also arranges the circuit board in the shielding structure in a chassis, The interference from other circuitry systems and power transformers is eliminated, and a lineout termination also uses the product line by the pin jack of a shielding structure, and the high coaxial cable of the shielding effect, and is raising the purity of sound. In order to correspond to the early bass of a riser, the original low-noise active servo power supply is adopted as the power source for audio circuitries. While this forms a feedback circuit combining constant-voltage IC excellent in the temperature stability only for a power source, and wide band IC excellent in the RF property, reduces a power-source noise by 20dB or more conventionally and raises an S/N ratio, The outstanding regulation (voltage stability) which also endures a car battery has been obtained. In order to eliminate various oscillations which have an ill effect on a tone quality, thorough absent resonance and unvibrated measures are taken. First, the three-tiered weight base is adopted as a base portion to the sound pressure oscillation transmitted from a speaker. This is what carried out integral moulding of a metals chassis, special dumping rubber, and the material in which the new materials TNRC (technics non Resonance compound) differ, and has acquired the high braking effect by transforming vibrational energy into heat energy. Moreover, special deadning rubber is used also for a cabinet top plate, and vibration proof is improved. Next, in the floor oscillation transmitted from a setting stand, the oscillation is held down with the double insulator structure by the floating of four large-sized insulators and optical decks. Besides it, 2 power transformers which are the sources of an oscillation inside a CD player also performed the rubber floating, and have prevented transmitting an oscillation of a transformer outside. In order to remove the noise component produced at the time of the D-A conversion of a music signal, the super clean digital filter original with an audio circuitry is adopted. The tone quality is improved with the combination of the 96th digital filter and an analog low pass filter with a high operation precision. Two digital output terminations, light and a coaxial, can be carried, and an audio signal can be direct transmitted to an external D/A-converter unit. The Copper-foil styrene capacitor and the electrolytic capacitor for audios are adopted as capacitors. Moreover, also with each part which constitutes an audio circuitry, from double-sideds of a physical characteristic and an audition testing, the study was repeated and the careful selection using of adopting extensively the resistor for audios which uses OFC lead wire and a non-magnetic-material cap etc. is carried out. The use efficiency ratio of laser light is high to the pickup which reads the signal of a disk, and 1 original beam scheme which has improved the SN ratio of a regenerative signal sharply is adopted as it. Furthermore, high play ability and endurance have been acquired by using of the aluminum die-casting base, a glass lens strong against a transition of a temperature or humidity, a phase difference scheme tracking servo, etc. By turning a dial by a fingertip, 2 speed search dial which can do a head search minutely is carried in right reverse both ways. The refresh rate per rotation can choose the 2 modes for about 1 second (slow) and about 30 seconds (fast), and a precise access of a three-frame (1 / 25 seconds) unit of measure is possible for it at the minimum. The linear motor is adopted as the actuator of the traversal mechanism to which a pickup is moved. With the original servo system which uses a microcomputer, the pickup migration between music is shortened at about 0.9 second. Moreover, when deceleration mechanisms, such as a gear belt, are lost, silence and an endurance are also improving. The programmable music scan which plays only the intro fraction of disk enrolment music one by one is carried. The play time per music can be set up freely till 1 to 99 seconds. Almost all operations carry the ten key wireless remote control which can be performed by a hand from a play and the elementary operation of a pause to a search, a repeat, and a time mode window. Moreover, the digital attenuator functionality whose volume can be controlled is also equipped by the level key. The preset editing functionality in which compact-disk edit united at tapes enrolment time is possible is carried.

In the power section, there are two completely separate power transformers, one for the digital electronics SL-P1000 Optical Deck and the other for the analog output stage. Then in each section of the player, there are independent power supplies for each & every circuit. Yes, its a power plant in there! This gives total isolation to each circuit for which there is an independent power supply. The transport section looks like any modern day CD drive except that it is better built! It has a high torque brushless direct drive motor and was one of the first CD players to use a linear motor for the pickup sled. This means that there is no actual rotating motor shaft connected to the sled via a series of plastic gears as on most players today. The pickup sled just floats along two steel guide Linear motor sledpoles to traverse the radius of the disc without any moving parts except for the sled itself, all powered by electromagnetic induction. This means that the sled can literally fly from the center of the disc to the outside of the radius in an instant and gives an end track access time of less than a second! All a bit different to Technics first ever CD player, the SL-P10. This also means that skipping back or forward through Sled Lock the tracks is also almost instant. Because the sled is free to slide forward and back, there is a lock accessed from the bottom of the player that holds it in position when the player is to be transported. The CD draw is a quiet, fast belt driven design and the draw is tough cast plastic and has a large center plate covered with soft cloth to protect the playing surface of the disc when it is inserted. The only player I know of with a better draw is the Sony CDP-101 with its solid cast aluminum draw and Internal Gold Connectors! metal runners. The main circuit board in the player is the control & servo board. This contains a Technics proprietary central control microprocessor, the DD motor drive, focus &Class AA VC-4 Amplifier sled servos and a Sony CXD1075 digital signal processor which connects to the digital outputs and to the internal D/A converters. The digital to analogue conversion and Class AA VC-4 sample & hold buffer amp section are at the rear and of course have their own separate analogue and digital power supplies. The sample & hold buffer amps for each channel are mounted on daughter boards on separate sides of the converter board and are mounted vertically and encapsulated in a bright blue resin. You can see one of them in the picture to the left under the gold output jacks. The internal analog cabling and connectors from the output buffer amp to the external RCA connectors is better than anything else I have ever seen, beautiful gold plate and high quality audio cables. If you look inside an ordinary CD player or receiver, its just a joke to see the quality of the interconnect cables used. Its even funnier to see people spending $100s on monster cables when they have no idea that the weakest link is inside their player!The heart of the converter is a pair of Burr Brown PCM54HP converters which appear to still be an active device and can be purchased for just $19-80 a piece from Digi-Key. Technics use two of these, one for each channel which eliminates any phase differences between the two channels. There is also a PCM54KP device listed on the datasheet which can be purchased for $27-93 each from Digi-Key. This version of the chip is the same as the HP version except that it offers reduced total harmonic distortion with distortion levels as much as 10dB less. As this would be just a drop in replacement, it would be a good upgrade for anyone wishing to bring an SL-P1000 bang up to date! Simply remove the old chips & drop in the new ones! Also of interest as shown in the diagram to the right, is the fact that the PCM54 series of converters provide for adjustment of the differential linearity error so that it may be reduced to zero. Differential linearity error (DLE) is the derivation from an ideal, 1 least significant bit change from one adjacent output state to the next. This is important in audio applications because excessive DLE at bipolar zero (at the major carry) can result in audible crossover distortion for very low level output signals. I think this would have been a great user adjustable feature for Technics to have added to the player and would have been a more interesting feature on such a high-end player than the 12dB variable output that it has. The rest of the CD players in the Technics 1988 line-up had a new D/A system that Technics called High Resolution 4 DAC 18 BIT. In fact looking inside a Technics SU-A60 digital control amp from the same year shows this to be yet more Burr Brown DACs, this time a PCM56P. As you can see from the datasheet, they are not 18 bit at all and in fact are a 16 bit serial DAC with a 96dB resolution just like the PCM54HP. So playing the SL-P1000 via its digital output through the SU-A60 makes no difference to the sound as expected. In fact playing the SL-P1000 with its internal DACs and comparing to the digital output playing through the high-end DACs in my Marantz AV-9000 makes no difference either that I can detect. So this leads me on to say that the same CD played with the SL-P1000 via the Marantz AV-9000 sounds the same as when played on any of my CD changers via the Marantz AV-9000. So I guess Ill leave the SL-P1000 DACs as they are and keep the original PCM54HPs!---------------I have Lot Sony, Krell, UHER, Tandberg, REVOX, Studer, Technics, AKAI, Hitachi and Pioneer reel to reel deck, Cassette deck, Pre amp, Power Amp, Speakers and e.t.c. from analog audio Golden Era 1970-1988, for sale Check out my other items!* If the buyer will be in city Montreal or nearby, can deliver free.
