Emotiva XPA-11 Gen 3 Eleven Channel Power Amplifier
Emotiva XPA-11 Gen3 is an eleven-channel audiophile power amplifier that delivers exceptionally accurate and dynamic renditions of all types of music.
The XPA-11 Gen3 offers the rare combination of excellent technical performance and superb sound quality, which makes it the perfect solution for listening to your favourite multi-channel music or for listening to movie soundtracks in a high-end home theatre system.
Configuration
The XPA-11 Gen3 features three High-Powered Single Channel Modules and four Stereo Modules – for a total of three high-powered channels and eight low-powered channels. This combination is perfect for a surround sound system with three large speakers in the front (Left, Right, and Center) and eight smaller surround or height speakers, and is especially well suited for a Dolby Atmos 7.1.4 or 5.1.6 system. The XPA-11 Gen3 would also be a great choice for driving a 7.1 or 7.2 channel surround sound system that also includes two pairs of smaller speakers in other zones.
Switch Mode Power
XPA-11 Gen3 features new high-current switch mode power supply (SMPS) - a lightweight, powerful, intelligent design capable of delivering over 3kW of continuous power with absolute reliability and extremely high efficiency. The cutting-edge SMPS offers the dynamic attributes of a classic transformer-based design with none of the drawbacks.
Like the best transformer-based power supplies, SMPS delivers plenty of continuous power to enable the amplifier modules to live up to their full performance potential, and plenty of dynamic power to ensure that musical peaks will never be compressed or limited. However, compared to transformer-based designs, SMPS is lighter and more efficient; it’s also fully regulated which ensures optimum performance under a wider range of load conditions.
Audio Performance
XPA-11 Gen3’s unique differential input stage, with cross-linked current sources, drives a balanced voltage amplification stage, and this advanced input circuitry delivers an incredibly accurate and pure audio signal to the complimentary, fully discrete output stage. Together they deliver a holistic, natural, and powerful listening experience.
Low-level musical details and dialogue emerge from a deep black background; musical crescendos are delivered with both stunning impact and precision. The wide bandwidth, low distortion performance of the XPA-11 Gen3 reveals every nuance of your high-resolution music sources and it has plenty of power to drive even difficult loudspeakers with absolute authority and control.
Class H Efficiency
Both amplifier modules used in the XPA-11 Gen3 utilise a fully analogue Class A/B output stage. The High-Powered Single Channel Modules feature highly regarded Soft-Switch Class H power supply topology, which increases their efficiency significantly without compromising the audio performance you’d expect from an Emotiva amplifier. They operate on a lower supply voltage at low power levels to minimise quiescent power consumption and standby power losses, instantly switching to a higher voltage rail when needed to ensure the signal passes cleanly and without clipping.
This process happens on a continuous basis in real time, allowing greater overall efficiency, cooler operation, longer component life, reduced power consumption and increased reliability. The Stereo Modules each deliver two completely independent channels of pure Class A/B audio power and sonically are perfectly matched to the High-Powered Single Channel Modules.
Dedicated Power Amplifier
Most experts agree that, if you want the absolute best sound quality and technical performance, you should use dedicated separate components. Thes X amplifier modules are designed to reproduce today’s high definition movie soundtracks and music sources with awesome realism, amazing finesse and precision, and without the slightest hint of strain or signal compression.
The specially designed 3kW switch mode power supply delivers the tightly regulated continuous power and massive reserves of dynamic power necessary to enable amplifier modules to perform to their ultimate potential. Together they deliver an experience that simply cannot be matched by multi-purpose components like receivers.
Modular Construction
The XPA Gen3 modular power amplifier is comprised of a heavy-duty chassis, which houses the oversized power supply, and up to seven amplifier modules. The XPA Gen3 can be purchased with anywhere between two and seven amplifier modules installed, and additional amplifier modules may be installed as more channels of amplification are needed (up to a maximum of seven modules).
The front panel display and protection system are designed to work with the maximum number of channels, and so need not be updated when the XPA Gen3 is expanded; on the rear panel, slots not occupied by amplifier modules will be covered with protective cover panels. All seven module slots in the XPA-11 Gen3 are already populated.
Circuit Topology
The XPA-11 Gen3 is a fully modular audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete, dual differential, high current, short signal path Class A/B amplifier modules, optimised Class H power supply topology and microprocessor-controlled fault protection. The XPA-11 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).
Modern Efficient Circuit
Optimised Soft-Switch Class H power supply topology delivers improved efficiency without compromising audio performance. Switched Mode Power Supply (SMPS) offers all of the performance of a traditional linear power supply, with improved efficiency and reliability, and reduced overall weight.
Quality Construction
Top quality parts and construction are used throughout for years of reliable trouble-free service. Heavy steel 4RU chassis with milled aluminium faceplate offers strength and rugged good looks. Solid machined gold-plated RCA input connectors provide a reliable connection with a wide variety of audio interconnects. Fully modular construction allows you to purchase as many channels as you need today, and then add more channels later when and if you need them.
