 YAMAHA A-S1200 Integrated Amplifier
 Acknowledging the golden era of Hi-Fi with
   its beautiful design, the A-S1200 boasts an
   impressive array of the latest technology to
   accurately deliver an emotional,
   purely musical sound.
 High quality components delivering exceptional
   musical expression
 Toroidal power transformer with enormous energy
   for a pure musical sound
 Gorgeous level meters convey dynamics and
   music pulse with a nod to the nostalgic Hi-Fi era
 Floating balanced power amplifier
 Mechanical ground concept maximizes rigidity
   for expressive and rhythmic bass
 Toroidal Transformer:
   Usually reserved for flagship Hi-Fi components,
   the A-S1200 benefits from the technical proficiency
   and absolute musicality of a toroidal transformer.
   Combined with an array of high-end Hi-Fi features
   and components, the toroidal transformer assists
   in ensuring the musical emotion is conveyed to
   the listener.
 Gorgeous Level Meters
    The level meters are both a nod to the nostalgic
    era of Hi-Fi, while simultaneously demonstrating
    the return of pure Hi-Fi for today’s discerning enthusiast.
    Visually presenting the dynamics and pulse of the music,
    the level meters imbue a warm feeling through their
    softly illuminated LEDs.
 Thick Wires for Ground Connection:
    Our low Impedance concept, aided by the
    thick wires for ground connection, is critical
    for componentry adopting the badge of
    premium Hi-Fi. This Yamaha design concept
    begins in our premium Hi-Fi components with
    the A-S1200, helping to present an open,
    natural sound stage, bringing the artist and
    listener closer together.
 Original Speaker Terminals
    Cut directly from pure brass, the luxurious
    speaker terminals comfortably fit the human
    hand for effortless tightening, achieving a highly
    secure connection.
 Mechanical Ground Concept:
    The A-S1200 adopts a Mechanical Ground
    Concept, inherited from both the A-S2200 and
    A-S3200. The concept begins with the bolts of
    the feet welded directly to the main chassis,
    followed with the large heat sink, power transformer
    and block capacitors also directly bolted to the chassis.
    Through this design, unwanted vibration is avoided,
    achieving expressive and rhythmic bass, presenting
    the "Groove" of the music to the listener.
 Chrome-Plated Iron Feet:
    Completing the rigidity of the amplifier are the
    heavy-duty chrome-plated iron feet.
