Emotiva XPA Gen 3 Modular Power Amplifier (Modular)
- E-piphany Product Feed
The power amplifier performs the simple but critical job of boosting the output signals from each channel of your stereo preamp or surround sound processor to the level necessary to drive your loudspeakers. While this may seem trivial, a really good power amp is essential to having a great audio system, because any flaws in the performance of your power amp are going to limit the performance of your entire system. Every amplifier in the new Third Generation XPA series was carefully designed to deliver superb technical performance, unsurpassed sound quality, and an exceptionally accurate and dynamic rendition of all types of music, thus ensuring that your entire system will sound its absolute best. Each individual XPA amplifier is modular, and can be customized to provide exactly the power and number of channels you need today, and expanded later if your needs change; and multiple matching chassis enable you to add even more channels, or more power, for a near endless variety of options.
The new XPA-3 is a three-channel audiophile quality power amplifier, and is perfect for powering:
The three important front channels of a 5.1 channel or 7.1 channel home theater system.
Connecting an XPA-3 to the preamp outputs of your current high-quality AVR is a great way to upgrade the performance and sound quality of the three critical front channels.
3 x High-Powered Single-Channel Modules
(four module slots remain available for future expansion)
275 watts/channel RMS into 8 Ohms; all channels driven
300 watts/channel RMS into 8 Ohms; two channels driven
490 watts/channel RMS into 4 Ohms; two channels driven
Why You Need A Dedicated Power Amplifier
Most experts agree that, if you want the absolute best sound quality and technical performance, separate components are the way to go. Our new Third Generation XPA series power amplifiers are all designed from the ground up to perform a single critical task – to accurately reproduce every detail and nuance of your music. By focusing all of our efforts on that one goal, we’ve been able to design an amplifier that performs its job with remarkable precision, and avoids most of the compromises that limit lesser designs.
Experience Meets Cutting Edge Technology
When we set out to design the latest version of our XPA series of amplifiers, we analyzed everything in every amplifier we’ve ever made, from front to back, inside and out. By combining years of design experience, with a thorough understanding of recent advances in audio technology, we were able to determine several areas where we could improve on our previous designs. After carefully weighing all the options, we kept the best features of our previous models, added some new technology where we determined it would actually deliver significant improvements, and optimized several operating parameters to ensure that it would all work together flawlessly. The new Third Generation represents a significant improvement for our highly acclaimed XPA series of amplifiers – and delivers improvements in both technical performance and sound quality.
All of the models in our new Third Generation XPA amplifier family are designed to reproduce today’s high definition movie sound tracks and music sources with awesome realism, amazing finesse and precision, and without the slightest hint of strain or signal compression. They deliver a listening experience that is far above anything you can achieve with multi-purpose components like receivers, or with other amplifiers in their modest price range. We’re talking about real-world power and fidelity that you can immediately hear and appreciate.
Regulated Switch Mode Power Supply (SMPS)
One of the main limitations with traditional amplifier designs has always been the power supply. Until recently, a power supply that could deliver enough current to run a modern high-powered amplifier required a bulky transformer and large filter capacitors. While these traditional power supplies delivered good performance, they were heavy, expensive, and inefficient. For years, precision components like preamps and processors used regulated power supplies, but regulated supplies powerful enough to be used in large amplifiers remained complex and prohibitively expensive.
Thanks in part to recent advances in power supply technology we’ve finally overcome this limitation. One of the design enhancements shared by all of our new XPA power amplifiers is our new, specially designed, high current, switch mode power supply (SMPS). Our powerful, intelligent new power supply offers all of the benefits of a classic transformer-based design, but avoids virtually all of the limitations. It can deliver over 3 kW of fully regulated power, which ensures optimum performance under a wide range of load conditions, and plenty of dynamic power to ensure that musical peaks will never be compressed or limited. However, it’s also more efficient, more reliable, and much lighter. (Our revolutionary new SMPS has enabled us to reduce the weight of our new amplifiers by about 30%, making them easier to ship, and easier to install in your equipment rack or shelf.)
Class A/B Sound Quality Meets Optimized Class H Efficiency
The High-Powered Single Channel Modules used in the XPA-3 utilize a fully analog Class A/B output stage, and our highly regarded Soft-Switch™ Optimized Class H power supply topology, which increases their efficiency significantly without compromising their superb Class A/B performance and sound quality. At low power levels, each channel operates on a relatively low supply voltage, to minimize quiescent power consumption and standby power losses. Then, when the demand for power increases, it instantly and seamlessly switches to a higher voltage rail to ensure that 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.
