A new approach to amplifier design.
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.
Note: To ensure that additional amplifier channels are installed properly, and function to our specifications, additional amplifier modules must be installed by Emotiva, or by your local authorized Emotiva service representative.
A Word About Power Ratings
Music is, by its nature, dynamic. While it’s relatively common for the two main channels in a stereo amplifier to be asked to simultaneously deliver high power levels, it is very uncommon for more than two channels to be called upon to deliver high power continuously at the same time, and this almost never occurs outside of laboratory test conditions.
In order to deliver the most dynamic performance where it counts - with real music - we have designed the XPA Gen3 modular power amplifier with a single immense power supply, which is able to deliver massive power continuously to any two channels, and to deliver huge amounts of power dynamically to any number of channels when and if called upon to do so.
The power ratings for the XPA Gen3 modular power amplifier are the same with both channels driven continuously in the two-channel version of the amplifier, and for ANY TWO CHANNELS DRIVEN CONTINUOUSLY in the versions of the XPA Gen3 configured with three, four, five, six, or even seven output channels.
In addition to this, because we always aim to provide the most complete information possible, we have also rated the other versions in terms of continuous power (under laboratory conditions) with all channels driven.
Also note that, while the exceptional sound quality of the XPA Gen3 modular power amplifier, and its two-channel continuous power rating, remain the same whether you choose to use a 120 VAC line or a 230 VAC line, the multi-channel power ratings are somewhat higher when you power the XPA Gen3 from a 230 VAC circuit. While the XPA Gen3 modular power amplifier will provide plenty of power for most home theater installations when run from a 120 VAC line, for the absolute best possible performance, we recommend operating the XPA Gen3 from a 230 VAC line.

When we set out to make the new X Series line, we analyzed everything in every amplifier we've ever made, from front to back, inside, and out. In doing so, we discovered several areas where our years of experience, and advances in audio technology, indicated that we could make significant improvements in our amplifier designs. After carefully weighing all the pros and cons, we kept the best features of our original designs, added a new set of optimizations and improvements, and the result became the foundation of our new line of audiophile amplifiers. The XPA Gen 3 is a whole new ballgame.
The new XPA Series amplifiers are fully modular and configurable at the time you order them. You can choose any configuration you want, from two to seven channels. All configurations are built on the same chassis, sharing one very robust power supply. If your needs change in the future, you can easily have more channels added. No need to get rid of a perfectly good two channel amplifier when you want to move up to surround sound. Why should you have to buy another amplifier when you’re perfectly happy with your current one, but you need a few more channels?
More power, Scotty!
In amplifier design, everything starts and ends with power. Sure, the sound quality is critical, and that’s where the amplifier circuitry comes in, but, if you don't have your power supply right, the best amplifier design in the world can't save you.
The new XPA Series utilizes a high-current switch mode power supply. It's a power supply capable of delivering over 3Kw of continuous power with absolute reliability and extremely high efficiency. It shares the dynamic attributes of a classic transformer-based design with none of the downside. It's lightweight, intelligent, and extremely powerful!
Massive old school transformers and giant filter capacitors are rendered obsolete. They just can't compete. It's a revolution in power design, and it's the backbone of the new XPA modular amplifier system. It's the way of the future, and it's here now.
Let's talk amplifiers
The XPA Gen 3 modular amplifier series uses the same core circuit topology as our legendary XPR series amplifiers. A unique differential input stage, with a cross-linked current source, drives a balanced VAS stage. The advanced input stage is tied to a fully complementary output stage and delivers a holistic, natural, and powerful listening experience. Low-level musical details and dialogue emerge from a deep black background. Its wide bandwidth, low distortion performance reveals every nuance of your high- resolution sources. The XPA amplifiers will drive difficult loudspeakers with absolute authority and control, and will keep their cool while doing so.
Our highly regarded Soft-Switch™ Class H power supply topology increases the efficiency of the new XPA amplifiers without compromising the audio performance you'd expect from an Emotiva amplifier. At lower power levels, the amplifiers operate on a lower supply voltage to minimize quiescent power consumption and standby power losses. When the amplifier control circuitry detects a fast rising input signal that will exceed the lower power voltage, it instantly switches to a higher voltage rail to ensure that the signal can pass cleanly without clipping. This process happens on a continuous basis, in real time, and it allows much greater overall efficiency than previous designs. In actual operation, the XPA amplifiers are cool running, which contributes to much longer component life, reduced power consumption, and increased reliability.
All of the benefits of a classic Class AB design without the wasted heat, weight, and power of a conventional fixed rail design - Cool.
Real Power. Really.
You can't even begin to compare the power capabilities of most existing AV receivers to the massive power capacity of our new XPA Series amplifiers. Even many "high-end" power amplifiers are rated with only a single channel, or sometimes with just two channels driven. Seriously, we can't make this stuff up. Maybe they come up with up with some marketing-driven "burst" power standard that exaggerates their performance. Or their marketing guys say hey, "instead of using an 8-ohm rating, let's do it at 6 ohms; that'll make a bigger power number!" Genius? Nope.
Emotiva XPA Series amplifiers are always rated with all channels driven –continuously - into 8 ohms. Period. (We do give you some of those other ratings as well, so you can compare our performance to that of our “competitors” on their terms.) Just ask many of our competitors to see their “all channels driven” power ratings and watch the dance begin... what should that tell you?
The bottom line is that our new XPA Gen3 amplifiers will deliver the full power and majesty of today's high definition movie and music sources without a hint of strain, loss of detail, or control. We're talking about real-world power and fidelity that you can immediately hear and appreciate. No excuses, no compromises, and no double-talk.
