EMOTION
Understanding music is to understand the emotion upon which music is created. The passion and story behind the music that drives artists to create. With unmatched experience in every facet of music creation, embedded deep in Yamaha’s DNA is an intimate understanding of the emotional essence of music and music creation. Conveying the artists’ emotion through our Hi-Fi equipment is a fundamental component of Yamaha’s design philosophy.
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 LED’s.
OPENNESS
An open sound stage presents the listener with a musical experience that is similar to being at the live performance. True Hi-Fi delivers this openness in the sound, transforming the listeners’ musical experience, bringing them closer to the artist.
Thick Wires for Ground Connection by Low Impedance Concept
Low Impedance concept, aided by the thick wires for ground connection, is critical for componentry adopting the badge of premium Hi-Fi. This design concept begins in Yamaha’s 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.
GROOVE
Connection with the music is achieved with the underlying groove and rhythm. A true representation of the music lets the listener feel the groove, and therefore not just hear the music but feel the story behind the music.
Mechanical Ground Concept
Warranting the ‘Premium Hi-Fi’ badge, 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.
Silver Plating Feet
Completing the rigidity of the amplifier are the heavy-duty silver-plated metal feet.
school Class AB analogue
The A-S1200 is an old school Class AB analogue integrated amplifier, with no digital inputs, streaming or signal processing onboard. Five unbalanced RCA line inputs are fitted, with one of them bypassing the volume control so it can be used as a power amplifier – plus an MM/MC phono input.
