Product Description:
Nostalgic Hi-Fi design. Today's Hi-Fi technology.
A nod to the past with the latest technology for a purely musical sound.
Emotion
Translating the emotional narrative of artists requires an intimate grasp of the music creation process. This profound understanding is woven into the fabric of Yamaha DNA, cultivated through extensive collaboration with artists to nurture their creative endeavors. It is this deep-rooted comprehension that empowers Yamaha to authentically convey the full spectrum of emotions embedded in the music to the listener.
Toroidal Transformer
Usually reserved for flagship Hi-Fi components, the A-S1200 benefits from the technical proficiency and absolute musicality of a toroidal transformer. This essential component, combined with an array of high-end Hi-Fi features and components, plays a crucial role in ensuring that the emotional depth of the music is faithfully conveyed to the listener.
Gorgeous Level Meters
The level meters on the A-S1200 pay homage to the nostalgic era of Hi-Fi while also symbolizing the resurgence of pure Hi-Fi for today’s discerning enthusiasts. These visually captivating meters not only present the dynamics and pulse of the music but also evoke a warm sensation through their softly illuminated LEDs.
Openness
True Hi-Fi isn't just about listening to impressive equipment; it's about the equipment disappearing, leaving only the live performance in the room. The openness of the music, the sensation of being within arm's reach of the artist, brings the music to life, transforming listening into an active, engaging experience rather than a passive one.
Thick Wires for Ground Connection
Yamaha’s low impedance concept, reinforced by the use of thick wires for ground connection, plays a pivotal role in distinguishing our premium Hi-Fi components, exemplified by the A-S1200. This Yamaha design philosophy is integral to presenting an open, natural soundstage, forging a deeper connection between the artist and the listener.
Original Speaker Terminals
Cut directly from pure brass, the luxurious speaker terminals of the A-S1200 are ergonomically designed to comfortably fit the human hand, allowing for effortless tightening and ensuring a highly secure connection.
Groove
It's not just about feeling like you're there; it's about experiencing the story within the music. Feeling the rhythm, the groove, and moving with the music. Only a true representation of the music can evoke such emotions and transport you into its world.
Mechanical Ground Concept
The A-S1200 incorporates the Mechanical Ground Concept, passed down from both the A-S2200 and A-S3200 models. This concept starts with the bolts of the feet being welded directly to the main chassis, followed by the large heat sink, power transformer, and block capacitors, which are also directly bolted to the chassis. This meticulous design effectively eliminates unwanted vibration, resulting in expressive and rhythmic bass, presenting the true 'Groove' of the music to the listener.
Chrome-Plated Iron Feet
Completing the amplifier rigidity are the heavy-duty chrome-plated iron feet.
