Specially Designed High Rigidity Chassis Eliminates the Effects of Vibration for Greater Sound Purity
As part of the no-compromise design policy for this amplifier, Yamaha created an advanced chassis with strong rigidity. Chassis stiffness is enhanced by an H-shaped cross frame that boosts mechanical strength, by adopting aluminum side panels that increase the stiffness of the housing and by a three-ply structure with independent top cover and side panels. Any external vibration from the rack or other sources is damped by heavy insulators. The A.R.T. (Anti-Resonance Technology) Wedge in the center of the bottom cover acts as an additional vibration countermeasure and firmly supports the internal circuits and delicate parts. In addition, the MX-A5000 has a double bottom, consisting of vibration control plates made of 1/8 inch (1.6 mm) black steel, the same type of construction used on the previous flagship model Z11. In order to support the heavy heat sinks and other parts, it has a left-right independent construction strengthened by a rigid-frame structure. The bottom frame reduces the transmission of vibration produced by the large power supply transformer and heat sinks. It also incorporates a heavy insulator that blocks external vibration.
