YAMAHA A-S1100 INTEGRATED AMPLIFIER COLOR SILVER WORKING CONFIRMED Description ?? Condition: Used Please confirm the condition by reviewing the images carefully. ?? Yamaha Pre-Main Amplifier A-S1100 MC Head Amplifier Included, Superb Condition Both the main unit and accessories are in excellent condition. There are no issues with operation whatsoever. This A-S1100, while inheriting the series concept from the A-S2100, omits balanced inputs to offer excellent cost performance. Its design, unmistakably Yamaha, is outstanding. It combines MOS-FET floating and balanced power amplifiers with a single-ended control amplifier configuration, designed exclusively for RCA connections, offering 128 voices and featuring a massive wave memory comparable to gigabytes through the use of a newly developed sound source LSI. This enhances its ability in performance, sound creation, and music production. ?Product Features? Outstanding channel separation and shortest signal path symmetrical construction. Prevents crosstalk between channels by distributing the power amplifier section symmetrically to the left and right, and adopts a symmetrical construction that minimizes the signal path by placing the preamp circuitry near the rear panel terminals. Thorough low-impedance design to support robust and dynamic low-frequency reproduction. Achieves a superior speaker damping factor of 250 or more (8?, 1kHz) through a thorough low-impedance design, such as screw-fastening of major ground points and capacity enhancement of large current paths. Along with a custom-made, high-capacity EI core transformer developed with a focus on speed and rise, it supports robust and dynamic low-frequency reproduction. Equipped with MOS-FET floating and balanced power amplifiers capable of delivering a rated output of 90W + 90W, equivalent to the higher-end A-S2100. The floating and balanced power amplifiers achieve complete symmetry (pull-pull operation) of the push-pull operation in the output stage by floating four sets of power amplification circuits, + and -, for each channel, and completely isolating all circuits, including the power supply, from ground, eliminating the influence of fine voltage fluctuations and external noise circulating the ground, a Yamaha patented technology. Adopts Yamahas unique 3-parallel volume & tone control, which employs three sets of volume controls per channel, with one set each for volume/bass/treble adjustment when tone is used, and three sets in parallel for volume adjustment when tone defeat is used, achieving both a simplified circuit configuration and high adjustment accuracy. Achieves higher sound quality and long-term reliability by incorporating custom-made, high-precision ladder-type electronic volume devices from New Japan Radio, which have been proven in the A-S3000. Incorporates a full discrete construction phono equalizer with MC head amplifier that inherits Yamahas tradition. The full discrete construction MC head amplifier section ensures high S/N and low distortion even when using low-output MC cartridges. Analog audio compatibility is also assured. Gold-plated cut type is adopted for all RCA terminals. Special legs to suppress external vibrations. Aluminum face remote control.

Please note that for special items, or depending on the destination country, different shipping methods may be used. ?? Depending on the country, certain items such as watches and sunglasses may experience delays during customs clearance. Please be aware of this in advance. ?? As liquids are difficult to export, ink will not be included with pens, etc. Even if there are ink bottles in the images, the contents will be removed before shipping. International Buyers - Please Note: ?? Import duties, taxes and charges are not included in the item price or shipping charges. These charges are the buyers responsibility. ?? Please check with your countrys customs office to determine what these additional costs will be prior to bidding/buying. ?? These charges are normally collected by the delivering freight (shipping) company or when you pick the item up - do not confuse them for additional shipping charges. ?? The customs declaration amount will be based on the selling price on eBay. It is illegal to underdeclare the declared amount, a practice commonly referred to as undervaluing, so it must not be done under any circumstances. Similarly, declaring items as gifts is also not permitted.
