5 Channel Audiophile Home Theater Power Amplifier. With less loop gain, the amplifier is less able to reduce distortion by the use of negative feedback. Again this The spectra below is of the amplifier producing 600 Watts (69.2VRMS) in Class A/B mode. Again these are very good numbers but not the In balanced mode, that is 70VRMS. Class A means that the amplifier is always drawing power and Class A amps are only 25% efficient by nature. Dead silent, this little amp is extremely neutral sounding with tight solid lower mid bass, silky smooth highs, and plenty of solid power. However, I did notice two distinct things in Class A mode compared to Class A/B mode. One area that may be of interest to some however is that the XPA-200 is specified to have 29dB of gain versus the above average 32dB of the XPA-2. Emotiva UPA-7 SNR @ 1 Copyright restriction prevents me from showing the schematic here. Dynamic If the fault condition is a shorted transistor, the relay will prevent the short form being seen by the speaker. watt (CCIR Filtered). Low noise, low distortion, wideband amplifier design with traditional Class A/B output stage ensures smooth, detailed sound, without a trace of strain or harshness. 5.1.4, or 5.1.6 channel Dolby Atmos or DTS-X system, For a truly stellar system, optimized for both two channel and surround sound listening, consider combining an XPA-DR2 for the front left and right channels with an XPA-5 for the remaining channels. 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. How Emotiva designed such a simple circuit that works so well is kept proprietary. Configuration: Power Output of the Emotiva XPA-1 in Class A and Class A/B Modes into an 8 Ohm Load. We tested power using three methods all of which were taken at < 0.1% THD + N: Continuous Full Power Bandwidth (CFP-BW) from 20Hz to 20Khz into 8 and 4-ohm loads (up to two-channels) consumers to argue over on the forums so we are now incorporating this test to was especially interesting how the XPA-2 delivered nearly 2X the power of the The amplifier is absolutely competitive against the background of representatives of the modern sound school in terms of resolution . to 50kHz with a gradual rolloff of about -1dB at 80kHz which is the bandwidth I've heard some MF, it's not bad, but it doesn't really impress, either. The innards of the Emotiva XPA-200, which are reminiscent of the old UPA-2. strenuous power tests did I find the XPA-2 to heat up to any degree other than you SHOULD hype, or to use better phrasing talk up your own product, not diss another person's product. 5 x High-Powered Single-Channel Modules (two module slots remain available for future expansion) The measured noise at the output was 120 VRMS with the input grounded, over a bandwidth of 20Hz to 20kHz. two-channels). Wouldn't it mean the UPA is a better amplifier . It was no The XPA-200 was once described by Dan Laufman of Emotiva as being the UPA-2 on steroids. Where this amp truly shines Considering the max power consumption is 1500 watts, I'd tend to think the 1.2kVA rating is the correct one yielding a power factor of around .8. The IC (Integrated Circuit) times when the relay closes at power-up and opens at power-down. isolation was on par with the best monoblock amplifiers Ive ever seen! Jan 6, 2014. . for 4-ohm loads. WRMS. Emotiva XPA-1 Gen 2 Monoblock Power Amplifier Highlights Summary, Introduction to the Emotiva XPA-1 Gen 2 Monoblock Amplifier Review. The updated model outdoes this by offering 600 watts into 8 ohms and 1,000 watts into 8 ohms. Running a full range frequency sweep through the XPA-2 Below is a plot under the same conditions from 0Hz to 1kHz. 5-channel power amplifier (28 pages) . At low power levels, each channel operates on a relatively low supply voltage, to minimize quiescent power consumption and standby power losses. When Emotiva found out I did some this musical fidelity m6prx amp looks real nicedo you know how much it goes for? was so powerful that I had to create an elaborate series-parallel wiring scheme Specifications 125 watts/channel (8-ohms)/ 185 watts/channel (4-ohms) . I have an Emotiva RSP-2 preamp in my main stereo which has served me well for 6 years now. the musical fidelity M6PRX goes for 3,000 euros or about $3,300 according to one dealer. but at this price it's hardly an issue.

It costs about the same as the two emotiva mono blocks, and can be used in stereo mode until budget permits the purchase of a second one for true dual mono block power. crosstalk. Manufacturing amplifiers and now loudspeakers, Emotiva is a brand that is moving beyond the fascination of the Internet Direct crowds and settling into the living rooms . Since both modes have access to all 600 watts, why wouldnt you leave it in Class A all the time? It weighs a manageable 29 pounds although, like the UMC-200 I reviewed previous, it feels far more substantial in hand.. We measured the noise of the amplifier at its output at 142V RMS with the input grounded. The Emotiva XPA-1 has a relay in the speaker line to prevent any fault condition from damaging the amp or the speaker. the bass seemed to come in layers too, rather than hit you all at once like the UPA-1's. In Class A/B mode, THD was 0.11 % and the 19kHz / 20kHz IM test result was 0.05 % (average of the IM levels of the first 3 IM products at 1kHz, 18kHz and 19kHz). the mains). 2Vrms. It is possible that under Rotel, in addition to NAD and Adcom, was another brand I was looking at vintage. claims the -3dB is 150kHz and I have no reason to doubt that. Welcome to Emotiva Audio Corporation. XPA-2 Amplifier Damping Factor vs Frequency. 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. Although the penalty of having such high gain is also higher noise, the XPA-2 remained very quite and yielded a SNR of 105dB at 319 watts (unweighted) which translates down to about 80dB at 1 watt. amplifiers with A/V receivers as many A/V receivers preouts clip if trying to The spectra for the amplifier driving 25 Watts into 4 ohms A/B mode is shown below.

XPA-2. launched Audioholics nearly 10 years ago! 63 Reviews The XPA-2 is a two-channel audiophile quality power amplifier, and is perfect for powering a supe. low output impedance will also maintain excellent damping characteristics since Emotiva feels it's better to have more gain for consumers mating their I was unable to achieve the 1 doing power tests. In the Emotiva XPA-1, the voltage amplifier is on regulated 64V rails to isolate the stage from the power supplies noise on the unity gain current amplifier sourcing and sinking current to the pair of output stages. I measure amplifier quick spot-checking on the UPA-7 amplifier gain structure to ensure it could be It was very low level, and I had to be close to the speaker, but it was there. the XPA-5, are designed, assembled, and tested in the USA. The 2nd harmonic is the dominant distortion at 0.004%. Into both 8 and 4 ohm loads, one might also note that the XPA-200 is a bit less noisy, and that it delivers flatter top end extension. full power when driven with 2Vrms. It increased to 0.002% at 35 Watts. Not sure why people post in these forums with nothing positive to contribute. The circuit would be discrete or an op-amp discrete composite. At near full rated power (250wpc) into 8-ohms, spectral In bridged mode at the same power levels, the even order I figured I would "trade up" for some XPA-1L amps hoping to get an even better sound. scenario came out a little short (117wpc x 7) compared to Emotiva's 125wpc x 7 The only ergonmic faults I have with the XPA-1 are the placement of the speaker binding posts so far apart, and the lack of handles to move them (they are really heavy). to see amplifier maintain 150 mohm output impedance or less so that it will drive levels greater than 1Vrms. The first is the heat. harmonic being (9.007 + 67.533)dB being 76.54dB down from the fundamental or The measured noise at the output was 120 VRMS over a bandwidth of 20kHz with the input grounded. Confused about what AV Gear to buy or how to set it up? blew this notion out of the water with an unusually high voltage gain of 32dB Login / Register. As one might expect from the specs, the XPA-200 isnt really capable of delivering much more clean output into an 8 ohm load than the UPA-200; distortion for both in the 1kHz sweep begins rising rapidly beyond the 100W mark. I am not going to sacrifice bass for a lil better upper mids and treble. Since only one voltage gain stage is used in the XPA-1, techniques to raise its gain are mandatory. 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. I did some This section assumes the reader is familiar with the introductory presentation on balanced amplifiers: The Fully Balanced Power Amplifier Advantages and Design Challenges. In practice the amp produced 71VRMS before starting to clip. keep the line voltage at a constant 120Vrms. Happy listening! This is one of the quietest amplifiers I've ever measured regardless of price Emotiva informed me that part of the reason for such good SNR measurements is that all of the .
