Yamaha CX-A5100 AV Pre Amplifier / MX-A5000 AV Power Amplifier - Black

By transferring the best genes, we’ve gone one step further. Yamaha, which reached one peak with the Z11, searched for the ideal AV Receiver and developed the Aventage separates.
Now, with the emergence of the latest 3D sound formats, the CX-A5100 has been included in the next generation of AV preamps, making the new dimension of video experience even greater.
The newly revised Cinema DSP HD3, the latest functions, and the best technologies and expertise have all come together here. By applying our unmatched craftsmanship to the expression of dynamism and resonance, we offer a whole new level of home theatre excitement.
Featuring the absolute latest technology. The 11.2 channel preamp that brings you new dimensions in sound reproduction
The CX-A5100 is our flagship AV preamp, featuring the latest versions of 3D surround formats, advanced network functions such as Wi-Fi and Bluetooth® compatibility, and full 4K support with HDCP2.2 compatible HDMI for the 4K era. In combination with the MX-A5000 power amplifier, you can enjoy not only a premier 3D sound fi eld Cinema DSP HD3 11.2 channel full-spec reproduction but also new dimensions of surround sound as found in the newest movie theatres - in your own home.
True sense of realism produced by the next-generation Cinema DSP HD3, compatible with all the latest formats
The CX-A5100 supports the latest surround sound playback formats such as Dolby Atmos and DTS:X. In addition to conventional channel-based audio, it is possible to create a 3D space in which separate acoustic elements can move freely, giving a sensation of the motion of “objects” above the viewer’s head that fully realises the filmmaker’s intentions. What’s more, the revamped Cinema DSP HD3 features newly developed signal processing algorithms to increase their appeal even further. With three sets of high performance processors for Cinema DSP, it is possible to maximise the theatre sound effect, accurately reproducing a new dimension of realism for a sound field with a rich sense of presence unlike any system you’ve ever experienced. And by supplementing the limited number of speakers in a home system with Cinema DSP to create the effect of a movie theatre space with a large number of speakers, you can experience a realistic cinema sound field with the sense of truly being immersed in a movie scene.
High Density Presence and Richly Detailed Sound Ensured by High Sound Quality Parts and Design
All channels use ultra-high performance ESS ES9016 DACs, which provide 192kHz/32-bit compatible superior SN ratio and dynamic range, ensuring faithful reproduction from Blu-ray and other players, as well as 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), they provide high precision D/A conversion. A new Volume IC realises low noise and superior sound orientation, and a superior low jitter clock circuit is used for clear and vivid network audio. In addition, the internal design separates the power supplies to the analogue circuit boards, eliminating high frequency noise interference from the digital circuits.
The shielded power supplies restrict noise radiation and the large power transformer minimises vibration.
YPAO-R.S.C Sound Optimisation with High Precision 64-bit EQ Calculation and Speaker Angle Measurement
YPAO analyses room acoustics and performs speaker angle measurements, then calibrates audio parameters to achieve the best sound at any of several listening positions. The height of the presence speakers is also measured, to optimise the 3D sound field. R.S.C. (Reflected Sound Control) corrects early reflections for studio-quality sound. YPAO also uses 64-bit EQ Calculation for realising the most natural room acoustics possible. YPAO 3D provides automatic sound parameter optimisation that maximises the 3D sound field effectiveness of Cinema DSP HD3 as well as Dolby Atmos.
Specially Designed High Rigidity Chassis Eliminates the Effects of Vibration for Greater Sound Purity
As part of this amp’s no-compromise design policy, Yamaha created an advanced chassis with strong rigidity. Chassis stiffness is enhanced by an H-shaped cross frame that boosts mechanical strength, by aluminium side panels that increase stiffness, and by a three-ply structure with independent top cover and side panels. The ART (Anti-Resonance Technology) Wedge in the centre of the bottom cover acts as an additional vibration countermeasure for the internal circuits and delicate parts.
Bluetooth Support, Wi-Fi Built-in and Extensive Format Compatibility
Bluetooth support gives you the convenience of wireless music playback, while Wi-Fi Built-in improves installation flexibility. These two features provide easy access to countless music sources. In addition, compatibility with FLAC/WAV/AIFF 192kHz/24bit, Apple Lossless and DSD 2.8MHz/5.6MHz formats means that you can easily play high resolution audio from a networked NAS, PC or USB.
AV Controller App Allows Convenient Control from a Smartphone
You can use the Yamaha AV Controller app to control power on/off and volume, select input and DSP modes and operate other functions from an iPhone or Android devices. You can also use in as many as 23 different languages and customise the interface by hiding unused icons and renaming functions. A tablet version is also available.
HDMI: 8 Inputs and 2 Outputs with Upscaling / Pass-Through, HDCP2.2 and HDR* Video added in HDMI 2.0a spec
The HDMI inputs and outputs support 4K60p Ultra HD video image pass-through. In addition, 4K Ultra HD upscaling boosts lower resolution images and supports 4:4:4 video signals for more vibrant and lifelike images, ensuring full enjoyment of 4k high definition video quality. The CX-A5100 also adheres to the HDCP2.2 copyright protection standard for 4K video transmission, and supports HDR (High Dynamic Range) Video which provide enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image.
Advanced HDMI Zone Switching
While standard HDMI zone switching can only send HD video programmes to the main and second zones, Yamaha’s Advanced HDMI Zone Switching adds the capability to choose from various audio and video sources for playback in either zone. An on-screen graphical user interface makes it easy to browse and select content to enjoy from the second zone no matter what is being played in the main zone.
Noise Resistant, Highly Reliable Balanced Connections and High Quality XLR Terminals for Long Subwoofer Cables
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-A5100 is not affected by this distortion, it uses 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. Even when each channel is used independently, the impact of noise flowing between the preamp and power amp is removed, minimising sound quality deterioration due to the connection. XLR terminals allow use of the long cables that may be needed to connect a subwoofer. The CX-A5100 also allows balanced audio input connection to high grade source components such as CD players.

MX-A5000 AV Power Amplifier
Absolute Quality, Massive Power.11-channel Power Amplifier delivers top-grade AVENTAGE Series performance. Incredibly clean, transparent output at all power levels. High rigidity chassis, high sound quality parts and reliable balanced connection for optimum performance, with flexible system building.
Overwhelming Power and High Density Presence Achieved by 11.2-channel Separate AV Amps
The MX-A5000 discrete structured 11-channel Power Amplifier delivers powerful driving force that provides superb quality and performance for all channels. Combined with the CX-A5000 11.2-channel Pre-amplifier, it 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.
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 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 MX-A5000 has a double bottom, consisting of vibration control plates made of 1.6mm 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.
Symmetrical Power Amplifier Layout
This is just one of the many design details that all combine to create a superior receiver. The interior of the unit has been precisely planned, circuit-routed and built so that the left and right channels are physically and electrically isolated. This naturally maximises channel separation, but also greatly improves signal to noise ratio and also helps to achieve a wide, open sound stage.
Highest Quality Parts Achieve High Power to 11 Channels and Unrestricted Speaker Drive
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 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 specially developed high capacity (27,000uF) block capacitors, it minimises 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 MX-A5000 and CX-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. And 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.
In Addition to 11.2-channel Output, 5-channel Bi-amping and Other Configurations Are Possible
The MX-A5000 and CX-A5000 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, for example, 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 for music play in a bedroom or kitchen, for example. On the MX-A5000, you can switch all 11-channel input jacks back and forth between balanced and unbalanced for each channel, further increasing system flexibility.
Auto Power Standby
Using less power saves money and is friendly to the earth. The MX-A5000 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.
Trigger Control for Synchronised Power On/Off
The trigger function allows automatic power synchronisation with other components that support this function. 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).
Speaker Impedance Selection
The Impedance Selector on the rear panel ensures that the MX-A5000 is in conformity with speakers of various impedances you may use.
- CH.2 A/B: 4 ohms or more (8 ohms or more when using CH.2 A and CH.2 B at the same time)
- Other channels: 6 ohms or more
