2-channel Integrated Amplifier
Enjoy superior audio quality with dedicated single-ended and high-grade integrated amplification that faithfully draws out all of the emotional and dynamic sound from your favorite players as only Yamaha can do.
Floating and Balanced MOSFET Power Amplifiers
Completely floating the entire power amp circuit from the ground removes any negative impact of minute voltage fluctuations or ground noise. Moreover, the output elements are comprised of MOSFETs, which provide a warm and natural sonic characteristic. The use of MOSFETs, which have the same polarity on the plus and minus sides, further evolves a complete symmetrical design by eliminating variations due to difference in polarity.
All Stage Fully Discrete Construction, Balanced Transmission and Low Impedance Design
The A-S1100 has a full discrete configuration during tone defeat by thoroughly separating the tone control circuit from the signal system. This not only increases response, but also improves slew rate and results in high range reproduction of greater vitality, richness and smoothness.
Symmetrical Design in Pursuit of Ideal Stereo Reproduction
The left-right symmetrical construction and the power amp blocks on the ends achieves greater separation of the left and right channels which is necessary for proper two channel stereo reproduction and ideal weight balance. This also dramatically lessens the impact of external vibrations and improves the quality of sound.
Large Capacity Power Supply Delivers Energetic, Dynamic Sound with Fast Response
The A-S1100 employs an original EI transformer, carefully customized for optimum compatibility with the chassis. Combining four large capacity carbon sheath block capacitors delivers an energetic sound, even during high volume.
Electronic Volume Control
A high-quality digital volume control specially designed by New Japan Radio Co., Ltd. consists only of ladder-type resistance. This removes the impact of slew rate decline (or coloring of the sound) to deliver higher purity in the sound and excellent, fast response to large volume changes and steep transients.
Discrete Phono Preamp
The phono preamp is comprised of an MC head amp and an equalizer amp, each of which are discretely configured resulting in a rich sound with pronounced musicality. Enjoy vinyl records with a Moving Coil or Moving Magnet phono cartridge and utilize the selectable switch on the back panel.
Level Meters
Level meters provide visual enjoyment with the rapid and delicate movement of the needles. The meter is illuminated softly from inside by LED, giving a warm, beautiful lamplight look. The level meters can be set to VU, Peak or remain in the 'Off' position.
Original Speaker Terminals
Complete inheritance of the emotional and dynamic sound delivered from Yamaha. Enjoy superior audio quality with dedicated single-ended, high-grade integrated amplification that faithfully draws out all of the intrinsic value of your favorite players or D/A converters.
