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.

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 Biamping 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 biamping for driving tweeter and woofer with separate amps. Furthermore, they allow biamping 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.

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
