Emotiva XPA-3 Three Channel Audio Power Amplifier

Supercharge your system.

A typical receiver is a well engineered series of compromises. It's give and take...size, cost, power, performance - you can't have it all. Don't get us wrong, there are some great receivers on the market today, with great features and great prices. Unfortunately, something's gotta give, and it's usually in the power amp.

Take a close look at the specs of most popular receivers. Now, take the top cover off, and ask yourself, how did they do it? How could that small transformer, a couple of capacitors and that little heat sink and fan be generating and dissipating all the power claimed?

Here's a typical power spec from a popular name-brand receiver that sells for around $2,000:

120W x 7 (8 Ohm 20-20kHz 0.09%THD) - Sounds great, doesn't it? But look a little deeper into the specifications, and you'll see it again, but listed as a 'Channel Power Rating'. What does that mean? It's called 'fine print...a disclaimer.

It means that one (maybe two) channels can make that rated output, at that specification for a finite amount of time. It doesn't mean that all seven channels, working at the same time, and at the same power level, can come anywhere close to the cumulative power rating of 840 watts that the specs indicate at first glance (7 x 120 = 840). You get the idea. Something had to give. That something was power.

So what's the answer? More power. In order to deliver a lifelike, clear and engaging cinematic and musical experience, you need REAL POWER...and LOTS OF IT. You need to give that receiver of yours a shot of adrenaline.

Add an XPA-3 to your receiver. Use it to power your left, center and right speakers. Let the receiver take care of the surrounds...that's easy. You'll notice an amazing improvement in the overall detail and dynamics, and an exceptional improvement in the clarity and natural presentation of voices and instruments. Wait until the action starts, and then hold on. Your surrounds will also spring to life, because a huge burden has been lifted from the receiver, allowing it to easily feed them the power they need.

XPA-3 = Supercharger.

Like all of our X series amps, It's a brute. A high current, 600 watt amplifier with a massive toroidal power supply, independent power block construction, at price that's impossible to ignore.

When we say 600 watts, we mean 600 watts. That's the minimum output power of the XPA-3, with all channels driven. No excuses, no small print. No disclaimers. Just real, honest power.

Combine it with an XPA-2 for an absolutely knockout 5 channel system. There are as many possibilities as there are different multi-channel setups.
