Toroidal transformer
Typically used in flagship Hi-Fi equipment, the A-S1200 benefits from the absolute musicality and technical prowess of a toroidal transformer. The A-S1200 amplifier combines a range of high-end Hi-Fi features and components, with the toroidal transformer helping to convey the feeling of music to the listener.
Thick ground wires provide low impedance
The low impedance concept, supported by thick ground wires, is a requirement for a high-end Hi-Fi product. This concept gives the A-S1200 an open and natural soundstage that brings the artist and the listener closer together.
High-quality speaker connectors
The screw terminals and specially designed parts are machined from pure brass and ensure a tight cable connection without compromising sound quality. The finger-friendly screws not only look good, but are also easy to tighten and loosen with little force.
Mechanical grounding concept
Like the A-S2200 and A-S3200, the A-S1200 also uses a mechanical grounding concept, which includes welding the feet directly to the chassis, large heat sinks, a high-efficiency transformer and capacitors directly mounted to the chassis. This eliminates unwanted vibration and achieves expressive rhythm in the music.
Structure
To complement the rigidity of the amplifier chassis, the A-S1200 is equipped with heavy-duty redesigned feet.
Floating and balanced power amplifier & MOSFET transistors
The basic structure of the power amplifier circuit follows Yamaha's own specially developed floating and balanced power amplifier technology. The plus and minus sides of the output stage have the same polarity, and the NFB (Negative Feedback) circuit and power supply stage are completely isolated for the left and right channels into four different plus and minus sides - this gives the output stage a completely symmetrical phase shift. "Floating" the entire power amplifier stage from ground eliminates any negative interference that small voltage fluctuations and background noise could cause. The MOSFET transistors in the output elements bring warmth and naturalness to the sound. Their polarity is the same on the plus and minus sides, which contributes to the ideal of perfect symmetry and eliminates variations in sound quality due to polarity differences. This is precisely the remarkable feature of a floating and balanced power amplifier. The result is sound with a superior signal-to-noise ratio and a very precise sound field.
State-of-the-art electronic volume control for ideal sound reproduction
The A-S1200 uses a high-quality digital volume control specially developed by New Japan Radio Co. Ltd. It uses only ladder-type resistors, eliminating voltage drop and the effect of sound coloration. The result is a cleaner sound and excellent, fast response to large volume changes and sharp transients.
Symmetrical design for ideal stereo sound reproduction
The left-right symmetry of the structures in the power supply and power amplifier sections enables high-quality separation of the left and right channels – which is very important for high-quality two-channel stereo sound reproduction – and optimal weight distribution. The chassis features a precisely adjusted edge-to-edge frame and redesigned metal feet (with optional spikes or pads). They give the device good mechanical rigidity and enable stable placement, significantly reducing the impact of external vibrations on sound quality.
Separate turntable amplifier
The turntable amplifier has a separate MC preamplifier and EQ amplifier. They enable you to hear the rich, beautiful sound of vinyl records when using both MC and MM cartridges.
Level meters provide visual representation of music dynamics
The A-S1200 amplifier features level meters on the front panel, allowing you to enjoy your music visually. The fast, precise movements of the meters are illuminated by a beautiful warm LED light. In addition to volume, the meters can be selected to show peak values. The meter cover is precisely fitted to the chassis.
Stylish design
The sophisticated design and construction of the A-S1200 amplifier reflect Yamaha's appreciation for exquisite craftsmanship and craftsmanship. This attitude stems from a long tradition as a manufacturer of world-class musical instruments. The metal front panel and wooden side panels are beautifully joined together using state-of-the-art processing techniques. The machined aluminum controls feel and look elegant.
Beautifully finished remote control
The remote control echoes the metallic design language of the aluminum-paneled amplifier. The buttons are arranged for easy and logical use. The volume and input source selectors control not only the A-S1200 amplifier but also the Yamaha CD player.
