Yamaha A-S1200 Integrated AmplifierYamaha
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.
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.
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.
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.
