The basic design of the power amplifier circuit adopts Yamahas own,
uniquely developed Floating and Balanced Power Amplifier technology.
Adopting output elements with the same polarity on the plus and minus
sides of the output stage, and also completely separating the NFB
(Negative Feedback) circuit and power supply into total of four plus and
minus sides of the left and right channels, results in thoroughly
symmetric push-pull operation of the output stage, Completely floating
the entire power amplifier 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 character. The use of MOSFETs, which have the same
polarity on the plus and minus sides, further evolves the ideal of a
complete symmetrical design, to eliminate sound quality variations due
to difference in polaritya major distinguishing characteristic of the
Floating and Balanced Power Amplifierresulting in sound with a superior
signal-tonoise ratio and superbly well-defined sound field. Dedicated single-ended amplifier for all types of audio sources
Since this device employs a dedicated singleended amplifier, it
provides excellent response in amplification of single-ended analogue
sound from all kinds of audio sources, such as CD players of D/A
convertersand the A-S1100 takes advantage of this in having been
carefully fine-tuned for optimum sound quality. By fully utilising
single-ended amplification, the A-S1100 transparently draws out the
intrinsic qualities of your favourite audio devices, including those
made by other manufacturers. All-stage full discrete configuration for strong reproduction of high notesThis amplifier adopts an all-stage fully discrete configuration
through all sound circuit stages, using only the most meticulously
selected high-precision parts from input to output. (Applicable during
tone control circuit defeat. ) The slew-rate of the audio signal has been
improved to bring lively and strong response to high musical notes.
Moreover, the tone control circuit lets you switch to defeat state and
enable a full discrete configuration that bypasses the op-amp IC of the
internal circuit, simply by setting the BASS/TREBLE knobs to their
center points.
Thorough low impedance design ensures powerful bass response with extremely dynamic, energetic feel
By strengthening the capacity of the high current route (raising the
section area of the cable core wire to about 60% of that of the A-S1000)
and by pursuing thorough low impedance design, including forming
screwclamped wire connections of major ground points, the A-S1100 boasts
excellent speaker drive power with a damping factor of more than 250
(8, 1kHz). Along with the large-capacity power source transformer
equipped with an EI core, this design delivers bass reproduction that is
both strong and uplifting. Superior quality electronic volume control for optimum sound
Weve utilised a high-quality digital volume control specially
designed by New Japan Radio Co. , Ltd. , which consists only of adder-type
resistance, removing the impact of slew-rate decline or colouring of
the sound, delivering higher purity in the sound, and excellent, fast
response to large volume changes and steep transients. Moreover, the
tone controls employ a triple-parallel method, minimising the
detrimental impact on sound quality seen with straight-line tone
controls. In addition, the bass, treble, and common circuits each
utilise simple construction in which the NFB of the amp is not used and
the CR elements are simply fixed in a straight line, ensuring
exceptionally pure sound reproduction even when tone control is applied
and superb response to audio signal transients. When tone defeat is
applied, straight signal flow from only one volume circuit to a discrete
configuration buffer amp is realised. Large capacity power supply unit delivers energetic, dynamic sound with fast response
The A-S1100 employs an original EI transformer, carefully customised
for optimum compatibility with the chassis. Combining four large
capacity carbon sheath block capacitors delivers an energetic soundeven
during high volumethat is possible only with the A-S1100. Moreover,
since the control amp and control system is equipped with twelve shunt
type local regulators that prevent deterioration caused by currency
fluctuation, a clean and stable power supply is achieved. The EI
transformer is mounted on the chassis using brass washer, restricting
internal vibration that would result in noise. Symmetrical design in pursuit of ideal stereo reproductionEnlarge
The left-right symmetrical construction with the power supply in the
centre and the power amp blocks on the ends achieves greater separation
of the left and right channelsnecessary for proper two-channel stereo
reproductionand ideal weight balance. Including fine tuning by a centre
frame which extends from the front to the back of the casing and
specially made metal legs (selectable from spike or pad), the A-S1100
has superb mechanical rigidity and installation stability that
dramatically lessens the impact of external vibrations on sound quality.
Discretely configured phono ampThe phono amp is comprised of an MC head amp and an equaliser amp,
each of which are discretely configured, resulting in a rich sound with
pronounced musicality, when playing vinyl records with both MC and MM
phono cartridges.
Level meters visually reflect the dynamics in the music
The centre of the main unit features level meters that provide visual
enjoyment of the music as well, 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 meter indicators can, along with
VU display, be switched to peak display, and can be selected according
to your preferences. The window of the meters has been precision-fit to
the panelcompletely flat, with no gapsfor an elegantly beautiful
appearance. Elegant design with luxurious real wood panelsThe refined design and construction of the A-S1100 reflects Yamahas
commitment to fine craftsmanship and art, uniquely drawing on its long
experience as a world-class musical instrument maker. The metal front
panel and the side wood panels have been beautifully integrated by the
masterful use of advanced processing technology. Moreover, the dials and
tone controls are machined aluminium knobs, for a richly textured
finish and graceful touch.
Original speaker terminals combine ease of use and beauty with high sound qualityOur meticulous obsession with quality continues through to the
speaker terminals, which are the last and crucial link in the audio
chain. Featuring screw type terminals. with originally designed handles,
these are created by cutting pure brass, enabling secure connection
with no reduction in sound quality. Contoured to the shape of human
fingers, they not only look beautiful, but can be turned easily and
fastened tightly with minimal effort. They are also compatible with
connections using banana plugs.
* Banana-plug compatible speaker terminals are available in some regions.
Remote control with simple design and superior texture
The supplied remote control features a design complementary to the
aluminium panel of the amplifier itself, with a simple,
easy-to-understand button layout and gorgeous metallic texture. In
addition to the basic volume adjustment and input switching controls of
the A-S1100, it can also be used for operation of the companion
