Profoundly accurate sound with the full expressive power of the music.
This material effectively reduces vibration caused by the power transformer, helping to create sound of greater clarity and spaciousness.
Comprehensive low impedance design, shortened signal paths and copper-plated chassisEnlarge In order to achieve the absolute purest signal transmission, capab.
For the base, to which the power transformer is installed on the inner frame, brass was selected by strictest examining the particular sonic properties of various materials by exhaustive listening tests.
The completely copper-plated inner frame has a structure which integrates the front-back and left-right frames with a convex-shaped highly rigid main frame as its base, reducing vibration coming from all directions.
Large toroidal transformer, solidly mounted with independent three-dimensional inner frame An independent three-dimensional inner frame has been employed in order to provide a more solid mount for the large toroidal transformer, which is installed in the centre of the A-S3000, considering the ideal weight balance.
The result is a dramatic reduction in signal loss, for remarkably pure audio amplification.
The newly developed chassis with this innovative structure helps to minimise the length of the signal paths and achieve low impedance, as well as providing high rigidity and anti-vibration benefits.
Moreover, the inner frame that supports the power transformer is shaped with ample space below it, allowing passage of the wiring to each circuit over the shortest possible route.
The power supply unit and amplifier circuits are thus structurally isolated, achieving an ideal chassis structure which thoroughly blocks the transmission of vibration.
The power amp circuit board and the weighty heat sink are attached to the left and right inner frames.
And the power source unit, which consists of a power transformer and capacitors, which are major sources of internal vibration, is fixed firmly with a three-dimensional structured inner frame, and is supported solidly by the front panel and the rear panel.
The bottom chassis and insulator ward off external vibration, and provide each circuit board a floating structure supported by an independent inner frame, thoroughly eliminating the impact of vibration.
The A-S3000 has adopted a newly designed highly rigid double structure construction in order to achieve profoundly pure and accurate audio amplification.
The supreme culmination of the Yamaha linethe A-S3000.
