Mechanical Ground Concept Chassis Design

Brass Speaker Terminals

Enjoy enhanced stereo sound with your favorite pair of speakers and the black Yamaha A-S1200 Stereo 180W Integrated Amplifier . It outputs up to 90W per channel at 8 ohms and features a switchable MM/MC phono input in addition to its five stereo RCA inputs. A 1/4" headphone jack with discrete amplification enables private listening. The A-S1200 includes a remote control as an added convenience.

Toroidal Transformer The toroidal transformer in the A-S1200 is designed to provide technical proficiency and musicality. Combined with an array of audiophile-grade hi-fi features and components, this transformer helps ensure you get the musical emotion you expect. Level Meters The level meters are both a nod to the nostalgic era of hi-fi and demonstrate the return of pure hi-fi for today's enthusiasts. Visually presenting the dynamics and pulse of the music, the level meters are designed to provide a warm feeling through their softly illuminated LEDs. Open Sound Stage The open sound stage is engineered to provide a musical experience similar to being at a live performance. Thick Ground Connection Wires The amplifier's low impedance design, aided by the thick ground wires, helps present an open, natural soundstage. Pure Brass Speaker Terminals Cut directly from pure brass, the speaker terminals are designed to comfortably fit in your hand for simple tightening to provide a secure connection. Mechanical Ground Concept The A-S1200 adopts a Mechanical Ground Concept, with the bolts of the feet welded directly to the main chassis, and the large heat sink, power transformer, and block capacitors bolted directly to the chassis. This design helps avoid unwanted vibration to achieve expressive and rhythmic bass, presenting you with the groove of the music. Chrome-Plated Iron Feet The chrome-plated iron feet help complete the rigid design of the amplifier. UPC: 027108958682
