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!

VACUM CLEANER

By Tom-9-6EL

from Dallas, TX

I only used this amp for 2 hours during a church service. I installed it into our sound system to run 4 small speakers and everyone thought I was running a vacum cleaner during the service. The cooling fan is the loudest I have ever heard on any component. This amp would have to be kept in a closet.

Not A Bad Amp

By Poco

from Pueblo, CO

See all my reviews

I purchased this amp as a replacement for a Gem that had a loud fan. I plugged this one in and was disappointed to hear another really loud fan. However, I happened upon the review by Anonymous Musician, March 22 and found his solution did quiet most of the noise. (Thanks a bunch!!!) I also added some felt pads on all fan mounting surfaces. (Note: This repair voids the warranty!) The amp provides good clean sound and appears to be a good buy for the money.

Great amp for the money!!!!

By SOS Sound and Lighting

4/10/06 I use this amp to power four 15" stage monitors, and it works perfect. It does not get warm, and does all it needs to do. If you are trying to run a pair of subs on here I think that would be foolish! But, to run in a bi amp system, or as a monitor amp it is awsome!

Does the job

By WELO

Bought one of these abut ten months ago to use as a studio vocal monitor amp and it finally torched itself last week. RIP. Where you gonna rent an amp for 9 bucks a month?One thing I noticed is it is not shielded very well. Wasn't until I replaced this one with an American Audio VLP-300 that I became convinced the ringing I was hearing wasn't a semi-blown monitor horn.

Nady XA-300

By Gary N.

from Texas

I purchased 2 of these amps. Within Days both went into fault protection mode. Paid Shipping ans sent them to Nady. 5 Weeks later I get these amps back and 1 right out of the box does not work; the second one dies the next day going up in smoke! Stay away from these China made products! Transformers & secondary voltage circuitry is Don't waste your money or your time!

Power out put over rated

By Mr.FourTrack

from Kansas City

See all my reviews

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

Not bad...

By yozilla4

from Firth, Idaho

See all my reviews

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.

Thanks for bailing me out!

By Anonymous

from Undisclosed

I was in a tight spot - I was skinless (out of money!) and in need - my PA head blew. I searched the options here and I was amazed to find a way out so cheap. I didn't expect much but got more than I bargained for. This amp has all the features I needed - especially a mono bridge switch for small jobs where I wanted to pare down to one speaker and parallel input so I don't have to use a Y jack. It doesn't POP when you power up and its light as a feather. It got me through my tight spot but I also found that it sounded good as well. When I pondered having my little Crown bridged as a back up it dawned on me - damn, just get another XA-300. It costs less to buy it new than fixing my old amp and two of them are lighter than my old amp. I can't say how it would hold up to six nights a week of pushing it to the limit but for my part time use it is perfect.

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!

Great Sound Unless you sit next to it

By Carl-GbfsR

from Nashua, NH

We ordered the XA-900 about six months ago and loved it. So we bought two of these last week,Mar 2006. They sound great in bridged Mono, I have not tried prallel or stero. I let them run for about 4 hours first with no load and then played some CDs through them to Test/Burn them in before using them live. The big problem we found was that unlike the XA-900 the 4 fans in each amps are noisy, and to make matters worse they change speed according to the ammount of power being used. The fans change in pitch with the baseline of the music being played. If you are not going be near these amps, they are a great deal.

Nice Price

By Mssg2URudy

from Riverside, CA

See all my reviews

I am pleased with the performance of the XA-300, it is comparably in quality to much more expensive systems. The price is simply unbeatable. I cannot comment on sound much because I am using franken-cabs that I have built from pawn shopped speakers and the like.

OK for the money

By North

from Franklin, WV

See all my reviews

I bought this to power a couple of older Peavey SP-1's. The amp works well enough for that, however I would not use this for recording as the fan is quite noisey. Great for live sound as long as you use it within the specs.

Great Deal - Great Price

By Vorris

from Tampa, Fl.

See all my reviews

These amps are great, especially for the price.Even though it's around 120 watts stereo @ 8 ohms (Which I'm running currently), the amperage makes up for it!Using just two of them, I power 2 18"'s and 2 12"'s with mids and tweets, and it sounds great, not to mention the frequency response!The only cons are:1. Make sure you can flip the energy bill.2. Make sure they have good ventilation.

great value

By Anonymous

from Undisclosed

Great Value for the money.Loud whine from cooling fans - I opened it up and the noise was coming from the left rear fan that is attached to the heatsink. Undid the heatsink and removed fan and discovered the problem is not the fan itself, but the harmonics from being attached to the heatsink. Drilled a couple holes and got a couple screws to attach it to the case like the one on the right rear, which makes it about 1/4 inch away from the heatsink. Problem solved, very quiet now.

Cheap

By sR3JaRHRd

from Illinois

Bought it as a backup for a small DJ rig. Power seems to be as advertised.Features are basic but thats what I needed.Extreemly noisy when 60% volume knob is passed. Sounds like the cooling fans are generating the noise. Really could use some additional noise filtering on the power supply. Sound produced is fine once you have overcome the noise generated.

Stereo Guitar Effects Amp

By pacAir

from Portland, Oregon

See all my reviews

I use the Nady XA-300 as a 120 watts per side stereo amp driving 2 Eminence Legend V12 drivers for my guitar effects (a Lexicon MX200... also an outstanding buy at MF). This system alongside my tube guitar amp (which is fed clean unprocessed guitar signal) gives me a 3-channel guitar setup that fills a room without overpowering it from a big amp alone.The XA-300 has worked flawlessly since day one and continues to perform without problems (mounted in a padded rack bag for protection). The front-panel level controls make balancing the system easy and the fan is very quiet and I never hear it on-stage. I got so much bang for the buck with this amp that I recently ordered another one! It works for me!

XA-300

By Kabby

from Tennessee

See all my reviews

I purchased this amp (XA-300) to use specifically for a monitor amp. I have read many reviews that mention noisy fans but did not find that to be the case in my experience. I have used this amp both indoors and out without flaw. This amp produces great sound, I have had no problems with clipping or distortion but I usually don't run my amps over 80%. If you need a good monitor amp or small gig amp, for the money you can't go wrong with this one.

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.
