Product Description Yamaha A-S1000BL Natural Sound Integrated Stereo Amplifier In Black From the Manufacturer The Yamaha A-S1000 Integrated Amplifier: An Affordable Sound Luxury The brilliantly expressive capabilities of Yamaha's floating and balanced design is now available to a wider range of music lovers. The power amp, power supply, and phono EQ circuits that contribute to the A-S1000's high sound quality are identical to that of the more expensive Yamaha A-S2000, while the line amp section and volume and tone circuits are nearly the same. Designed to take full advantage of the excellent sonic qualities of the matching Yamaha CD-S1000 Super Audio CD Player, the A-S1000 will also bring out the best of other high performance components. Heat sink Huge power transformer Custom-made block capacitors Preamp board Yamaha's All-New Approach to Achieving Superior Performance The development of the modern audio amplifier began in the 1960s with the introduction of full-transistor amplifiers. In the 1970s, pure complementary configured power amps appeared, made possible by high output PNP-NPN transistors, and became the dominant type of analogue amplifier. Now digital amps have become popular for their high conversion efficiency and superior operating precision, as well as for their lower weight, size, and heat production as compared to analogue amps. Some manufacturers of audiophile-quality amps are working to improve the traditional pure complementary analogue amplifier, while others are seeking to achieve higher sound quality from digital amplifiers. But Yamaha has developed a third, superior approach. The Floating Balanced Power Amplifier uses patented technologies featuring power transistors with the same polarity at the output stage to achieve completely symmetrical operation. This method, used in the A-S1000, combines a floating balanced power amp section with a high quality preamp section. Simpler in configuration yet with many of the same sound quality features as the ultra high-end A-S2000, it will deliver excellent performance with the CD-S1000 Super Audio CD player and other high quality components. How Does the Floating Balanced Amplifier Design Work? Completely symmetrical left-right construction View back panel Floating Balanced Power Amplifier With the A-S1000, Yamaha has taken the bold step of using a floating balanced configuration to update the power amplifier for serious music fans. This method, which is completely different from the pure complementary circuit that has been the main type for the past four decades, features identical polarity on the plus and minus side of the output stage. By completely isolating the plus and minus sides of the left and right channels of both the NFB and power supplies, it achieves perfectly symmetrical operation in the output stage. The use of four sets of floating power supply units (not connected to earth), provides further operating precision. The result is very low levels of noise and distortion for exceptionally pure and transparent sound quality. Triple Parallel Electronic Volume and Tone Controls Conventional audio amps have the volume and tone control circuits arranged in a series (in line); when the tone controls are used, the signal route becomes more complicated, which can lower sound quality. Many high quality amps therefore have a default circuit that can be selected to bypass the tone controls, but this forces you to choose between tone control and optimum quality. The A-S1000 is one of the first amplifiers to avoid this problem by employing triple parallel electronic volume and tone controls, providing maximum sound quality even when the tone controls are used, because the signal goes through fewer ICs, so there is less noise. When the tone controls are set to the center position, the passive element used for tone control is bypassed, so the three volume elements connected in parallel operate solely to drive and control the volume for more efficient use of the power output. Each volume element is an ultra-high quality device and an analogue potentiometer is used to provide a very smooth operating feel. Fully Discrete Phono Equalizer and MC Head Amp The A-S1000 uses a fully discrete phono equalizer circuit, whose quality is comparable to those in high-end control amps. And with its high priority on maximizing musical response, it is also equipped with a discrete head amp for MC cartridges. If you enjoy listening to records via high performance cartridges, the A-S1000 is an ideal choice. Power Supply That Cleans Itself Power is provided by four large-capacity power supplies that are completely isolated from earth. In the preamp stage, the combination of a low-current circuit that prevents the occurrence of noise due to current fluctuation and 12 shunt regulators supply all stages with clean and stable power, so you won't get distortion from a dirty power source. The extra-large power transformer, the carbon sheath block capacitors and other parts that directly affect sound quality were chosen only after extensive testing. Symmetrical Construction Mimics the Benefits of Having Separate Amps Although it is an integrated amplifier, the A-S1000 has a completely left-right symmetrical construction that makes it virtually the equal of separate amps. A central reinforcing bar ensures that the chassis is totally rigid. Specially Designed Feet Dampen Vibration to Reduce Jitter The base is equipped with height-adjustable, solid steel feet that maximize stability and thoroughly dampen any external vibration.

Actually it's tube buffer + amplifier work model.both function is alone, the music input to 6J1 tube buffer preamp and output to daul NE5532(TI)(each chip for each channel) amplifier part, after music output to your headphone. else ,In back of the P2-1. you will find a OUT interface. that the 6J1 buffer preamp pure output.you can use it as a buffer preamp for your other power amplifier, that's interface music isn't through the headphone amplifier part.so. it's very helpful for install it in your home audio system too. get more warm sound. Secondly: this P2-1 powered by 12VAC, and this list included a transformer already. with both voltage for choice. 110V or 220V,i will sent correct one to you by your order address. Outside shell is made by aluminum, good quality. P2-1 support power to 12~200ohm headphone. so. make sure your headphone is in this ohm range.About the tube.. each tube for each channel. and the tube will light up when turn ON.because there is a LED under the tube. about the tube itself. inside the tube. also will light up. but just weak light. that's normal.don't worry about that.There are 2 headphone interfaces, there are 6.35 and 3.5,Both interface are in parallel connect.so. if you want to get best sound. don't plug 2 headphones in them at same time.
