-Yamaha MXA5000 Power Amplifier
The discrete structured 11-channel Yamaha MX-A5000 Power Amplifier delivers powerful driving force that provides superb quality and performance for all channels. Combined with the CX-A5000 Preamplifier, it achieves overwhelming silence and sound filled with dynamic feeling, the goal to which Yamaha constantly aspires. With all types of sound sources, the Yamaha MX-A5000 Amplifier will provide an incredibly clean and transparent performance that immerses you in the soundstage at all power levels.
As part of the no-compromise design policy for the Yamaha MX-A5000 Power Amplifier, Yamaha created an advanced chassis with strong rigidity. Chassis stiffness is enhanced by the H-shaped cross frame that boosts mechanical strength, by adopting aluminium 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 centre of the bottom cover acts as an additional vibration countermeasure and firmly supports the internal circuits and delicate parts. In addition, the Yamaha MX-A5000 Amplifier has a double bottom, consisting of vibration control plates made of 1.6mm black steel. 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.
The Yamaha MX-A5000 Power Amplifier 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 realise 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 27,000uF block capacitors, specially developed for the Yamaha MX-A5000 Amplifier, it minimises energy loss and features power supply capacity with generous headroom. This ensures sound capable of superior musical expression. The high quality gold-plated speaker output terminals are compatible with Y plugs for optimum speaker connectivity.
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 Yamaha MX-A5000 Power Amplifier and CX-A5000 Preamplifier 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 such as that where each channel with the XLR is used selectively, the impact of noise flowing between the pre-amp and the chassis of the power amp is removed, minimising sound quality deterioration due to the connection.
The Yamaha MX-A5000 Power Amplifier and CX-A5000 Preamplifier are designed to allow flexible system building. Complementing their 11-channel output, that maximises Cinema DSP HD3 performance and makes the most of the capabilities of the speakers, they also support bi-amping for driving tweeter and woofer with separate amps. Furthermore, they allow bi-amping of all five channels using the 11 internal channels. Extra amps can be used to power multiple zones in addition to the main room, letting you configure your system to provide output in other rooms. On the rear of the Yamaha MX-A5000 Amplifier, you can switch all 11-channel input jacks back and forth between balanced and unbalanced for each channel, further increasing system flexibility.
The 12v trigger function of the Yamaha MX-A5000 Power Amp allows automatic power synchronisation with other components that also support it. Connecting a preamp, for example, to the Trigger In jack turns the power on and off together with the preamp. Connecting another component such as a subwoofer to the Trigger Out jack syncs the power of that component to the MX-A5000. In addition, the input from the Trigger In jack can be output in a cascade connection to control the power of another component such as another power amplifier (Through Out). The Yamaha MX-A5000 Amplifier also has an Auto Power Standby function that will turn the power off after eight hours. It can be turned on and off via a rear panel switch, and will be overridden by the Trigger function.
