The AVENTAGE CX-A5100 11.2-Channel A/V Preamplifier from Yamaha features 3D surround formats, network functions such as Wi-Fi and Bluetooth compatibility, and full 4K support with HDCP 2.2 compatible HDMI. In combination with the MX-A5000 power amplifier, you can experience a 3D sound field and Yamaha digital signal processing with CINEMA DSP HD3 in an 11.2-channel speaker configuration or a 7.1.4-channel configuration with Dolby Atmos or DTS:X surround sound formats. This device includes digital-to-analog conversion for all channels, as well as advanced HDMI zone switching that allows A/V switching to multiple zones. The 11.2-Channel Preamplifier offers 4K Ultra HD video upscaling with High Dynamic Range (HDR) support via its HDMI 2.0a inputs.
With the free MusicCast app, the CX-A5100 can be expanded to deliver wireless multi-room audio playback, all controlled by an app. The preamplifier also supports AirPlay, Spotify, Pandora, and other music streaming services through the free AV Controller app. The AVENTAGE CX-A5100 is constructed with an aluminum front panel, an H-shape cross member frame, and a rigid bottom frame.
 
 
Noise Resistant, Highly Reliable Balanced Connections and High Quality XLR Terminals for Long Subwoofer Cables
Electrical noise may be generated from connections with other AV components, including the connections between them as well as from external noise sources. To ensure that the CX-A5100 is not affected by this distortion, it uses balanced connections that are highly noise resistant t the same type generally used in pro audio equipment. Even the unbalanced RCA connection uses a ground-sensing transmission method that achieves a simple and balanced transmission. When each channel is used independently, the impact of noise flowing between the preamp and power-amp is removed, minimizing sound quality deterioration due to the connection. XLR terminals allow for the use of long cables that may be needed to connect a subwoofer. The CX-A5100 also has a balanced audio input connection to high-grade source components such as CD players.
 
Sound Tuning Achieved with High Quality Parts for Optimum Performance
Every single part in an AV receiver affects the sound quality. For AVENTAGE models, extra time is taken to find (or develop) the exact parts needed to achieve the highest performance possible. Sound technicians go through a testing process to, in effect, “tune” the receiver’s sound.
 
High Density Presence and Richly Detailed Sound Ensured by High Quality Parts and Design
All channels use ultra-high performance ESS ES9016 DACs, which provide 192 kHz / 32-bit processing with a superior SN ratio and high dynamic range, ensuring faithful reproduction from Blu-ray Discs and other players, as well as from high-resolution source inputs over the network. Matched to the design of the DAC circuitry, which achieves stable ground potential (DAC on Pure Ground), they provide high-precision D/A conversion. A new Volume IC realizes 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 analog circuit boards, eliminating high frequency noise interference from the digital circuitry. The shielded power supplies restrict noise radiation and the large power transformer minimizes vibration.
 
Specially Designed High Rigidity Chassis Eliminates the Effects of Vibration for Greater Sound Purity
As part of this preamp processors no compromise design, Yamaha created an advanced chassis with strong rigidity. Chassis stiffness is enhanced by a three-ply structure that incorporates an independent top cover, aluminum side panels and an H-shaped cross frame. The ART (Anti-Resonance Technology) Wedge in the center of the bottom cover acts as an additional vibration countermeasure for the internal circuits and delicate parts.
 
Aluminum Front Panel Offers Visual and Aural Benefits
All of the AVENTAGE components feature the same sleek, clean design, with an elegant aluminum front panel and silky touch volume/selector knobs. The aluminum front panel is used to effectively shield sensitive circuitry from external noise and electronic radiation generated by dimmer switches, fluorescent lighting, video monitors and so on. This ensures optimum sonic performance in the widest range of installation environments.

4K Ultra HD Full Support with 4K60p, HDCP2.2, HDR* Video and BT.2020 pass-through
This AV receiver completely supports with the latest HDMI standards. Thanks to transmission of 4K video at 60 frames per second pass-through, you can fully enjoy the high definition video quality of 4K without degradation. It also adheres to the HDCP2.2 copyright protection standard for 4K video transmission. It also 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. Furthermore it supports wider color gamut of BT.2020 pass-through.
*A future firmware update will be required to enable HDR.
