I was a little hesitant to purhase this cheap amp just because of all the poor reviews. I couldn't afford anything more, so I still bought it. It's better than what I expected. The amp never pops while shutting it on or off which I had problems with on other amps. The loud fan that everyone talks about gets louder the harder you hit the amp, so if you aren't using it, you don't hear it. I have it sitting on the bottom of my rack powering some Event 20/20 monitors, and they work perfect together. I can't even hear the fan because it's buried by equipment and the speakers are too loud once it starts making noise. I have been hitting the amp about 3/4 power for weeks now, and it eats it up. I would trust it to power my live sound monitors if needed. I wouldn't bother opening it up to fix the noise. I would rather have the warranty. These reviews make the fan seem worse than it really is. You pay for what you get, and for the price of this amp, it's worth more than what it costs. Yet, it isn't perfect obviously. The only one complaint that I have, is that it doesn't hit well below 70hz. My QSC amp which has too much power for my studio hits down to 50hz according to my RTA, but the NADY like I said has trouble with the real lows. Everything above 80hz is just fine, I have my sub to test my real lows.E-mail me if you have any questions.

I bought 3 of these Nady XA-300 amps, in a hurry to beef-up my PA (main highs & mids, monitors), after not playing for a while. The ?gig? was the company Christmas party, where I had just started the new job a couple months before. I was cautious at the price, but I figured, "how bad can anyone mess up a simple power amp?" so I ordered them.The first one out of the box went into fault/protection mode as soon as I turned it on, with no speakers connected. The manual said the front panel indication was speaker impedance mis-matched or too low, but nothing was even plugged in?! It never reset.The second amp did exactly the same thing during set-up and sound-check ? I started getting really nervous! The third made it until the last two songs, then followed suit. One did eventually reset after cycling power, but I couldn?t trust them.My boss (performing with us) and everyone else was gracious enough not to hold the hardware failure against me, and thankfully I still have a job, after almost ruining the whole party?!I learned my lesson: you really do get what you pay for!

6 Months!?

By kazukirec

from Nashville

If you want an amp that will work for 6 months, then fizzle out after 10 minutes of use, this is your amp. I never pushed the volume even CLOSE to halfway and it just tuckered out. I took precautions to cool it properly, not overload it, etc... Just not a good product. Perhaps I should have realized that there's a reason they are so cheap.

Use Them Properly

This is a clean sounding little amp. Power rating really is about 100 watts per channel. Just dont over drive it. Pay attention and use it for its original intention. I use this to power monitors when playing small bar gigs. We are a 4 pcs-blues jazz group and we run it at about half to two thirds volume and it works great- gig after gig.---just use it for what it was intended for.

100 days

The amp went into protect mode one week after 90 days or so. If you bargain shop, you will spend the difference in maintenance and repairs. I just got my tapco j-1400 it rawks!

Not bad...

By yozilla4

from Firth, Idaho

I had this amp for about 2 years and it served me well. It took lots of abuse such as overloading and getting tossed around and kept going for 2 years. The setup I used was this into 2 15" Kustom speakers. Often borrowed 2 10" monitors from a friend to pair with the mains and it worked great.After a year it did start to have issues with randomly going into protection mode, and now it just stays in protect.Pros-CheapQuietLightCons-Wish it had 1/4" outputsGoes into protection mode for no reasonOverall it is a good deal for the money. Great for monitors and garage band practices, but shouldn't be used for powering mains at live shows.

Woa oh no

First when i saw this i was like dude no way a power amp for only that much money. So i got it and it worked great for just practicing with my band but then we played this small private party and it went to protect mode and screwed us over thank God for this dj that was there and he hooked us up but that was just really lucky don't get caught up in this horrible technology save your money for something better.

Power out put over rated

By Mr.FourTrack

from Kansas City

Power RMS rating over rated sounds like about 50 watts other than that it is a good amp. Great cooling, great protect mode,good sound when levels are set right, but way underpowered.For the price it would make an ok monitor amp

good price for staring out.

Just starting out djing live, I was nickel & diming my PA, for the price it is very good quality sound. I do recommend a power conditioner.But over all good price & sound for starting out.

I like it!


from FL

Using this Amp on two JBL 4312 Control Monitors, they sound great! The home theater receiver I found them hooked up to did them no justice.This amp is nice and cheap, and really gives you a bit of bang for your buck. I really like this product, and will probably buy Nady again sometime.
