Specially Designed High Rigidity Chassis Eliminates the Effects of Vibration for Greater Sound Purity
As part of the no-compromise design policy for these two amplifiers, 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, both models have a double bottom with the MX-A5000’s consisting of vibration control plates made of 1/8 inch 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.
Highest Quality Parts Achieve High Power to 11 Channels and Unrestricted Speaker Drive (MX-A5000)
The MX-A5000 uses a current feedback power amp with a three stage Darlington circuit that has superior phase properties and is resistant to speaker impedance fluctuation. To fully realize its inherent power, it uses high quality parts with superior sound quality that were strictly selected based on listening tests.
The power supply transformer is a specially developed high output, high efficiency, large-size toroidal transformer. With two specially developed high capacity (27,000μF) block capacitors, it minimizes energy loss and features power supply capacity with generous headroom. This ensures sound capable of superior musical expression. The speaker output terminals are high quality gold-plated types and are compatible with Y plugs for optimum speaker connectivity.
Noise Resistant, Highly Reliable Balanced Connection
Electrical noise may be generated due to connection with other AV components and even to the connection between them, as well as from other sources of external noise. To ensure that the CX-A5000 and MX-A5000 are not affected by this distortion, they use balanced connections that are highly noise resistant—the same type generally used in pro audio equipment. Even the RCA unbalanced connection uses a ground sensing transmission method that achieves simple balanced transmission. In cases where each channel with an XLR is used selectively, the impact of noise flowing between the preamp and the chassis of the power amp is removed, minimizing sound quality deterioration due to the connection. The CX-A5000 also allows balanced audio input connection to high grade source components such as CD players.
Overwhelming Power and High Density Presence Achieved by 11.2 Channel Separate AV Amps
Making full use of Cinema DSP HD³, the pinnacle of three-dimensional sound field reproduction, the CX-A500 AV preamplifier realizes detailed, accurate sound imaging. The MX-A5000 discrete structured 11 channel power amplifier delivers powerful driving force that provides superb quality and performance for all channels. Combining these two achieves overwhelming silence and sound filled with dynamic feeling - the goal to which Yamaha constantly aspires. With all types of sound sources, you will enjoy a deep resonance that immerses you in music with the full scale presence of 11.2 channels for the perfect home theater experience.
High Density Presence and Richly Detailed Sound Ensured by High Sound Quality Parts and Design (CX-A5000)
In the CX-A5000, all channels use ultra high performance ESS Technology ES9016 SABRE32™ Ultra DACs, which provide 192 kHz/32-bit compatible high S/N ratio and dynamic range, ensuring that it can faithfully reproduce audio signals from Blu-ray Disc™ and other players and high quality signals from high resolution sound sources input through networks.
Matched to the design of the DAC circuit which achieves stable ground potential (DAC on Pure Ground), then ensure high precision D/A conversion. The OP amp is a high-grade type adopted only by flagship models for maximum signal purity. It realizes even more detailed sound by adopting a three-layer circuit board design that completely separates the digital, analog video and analog audio circuit boards, which have different noise levels and frequency bands, and by design that provides the shortest possible circuit route. Further, by separating the power supplies to the analog circuit boards, it eliminates high frequency noise interference from the digital circuits. The shielded power supply restricts noise radiation and the large power transformer minimizes vibration.
