Rockville RPA9 2-Channel Professional/DJ Rack Mount Power Amplifier

I purchased the Rockville RPA9 to power subwoofers for my DJ setup, and it has exceeded my expectations. The amplifier delivers clean, powerful sound with plenty of headroom for small to medium-sized events. I especially like the flexibility of having RCA, XLR, and 1/4" inputs, plus Speakon and binding post outputs, making it easy to integrate with different equipment. The built-in protection circuits and cooling fans have kept the amp running reliably during long sessions without overheating. For the price, the build quality is impressive, and it performs much better than I expected from a budget-friendly amplifier. If you're looking for an affordable amplifier to drive passive speakers for DJ gigs, karaoke, or live sound, the RPA9 is a solid choice. Just remember to match it with the correct speaker impedance and don't rely solely on the advertised "peak" wattage—look at the RMS ratings when planning your system.

Almost did 4 start, because it's not perfect, but thr only bitch i have is one fan is a little weak, but it hasn't overheated to the point of blowing up yet. Have had 2 of these for 2-3 years, I never write good reviews until I am satisfie that the item is well built and durable. (too many seem to do 5 stars just because something works upon arival). at this price, I am amazed at a great power amp. Sounds good and will definatly blow up a pair of Mach2 160W speakers. however, I agree with the reviewers who say the fans are too loud. Would be fine in a Band setting with high Volume, but in the living roo at low volume, they need to be in another room, Otherwise this is one of the best deals I ever ran into!!!. great with a Behringer mixer ahead and XLR feeding these. Feeding a pair of Mach2s inthe house, and the other, a pair of Mach2s outside. Have to be careful with the amplitude so not to blow the speakers. Can hear clearly 1/4 mi away.

Okay, I bought a pair of these back in June but decided to wait a little before posting a review - mostly because of a few "reliability" issues noted by others. I can happily report I have had no such problems. Admittedly working with those amps had a rough start: While they are exactly 2u high, the holes in the flanges force them to not align with the rest of the gear in my rack. Yeah, I can do puzzles and stuff but after running through the possible installation permutations it was clear proper alignment was not possible. In the end I just ended up drilling new holes in the amp's flanges. See the attached pics. The first is a screen shot from the Rockville video and the second a picture of my mounting , washers have subsequently painted black so it actually looks less dorky. Notice the gap (unacceptable!) in the screenshot of the video and the complete lack of gap in my rig. There is an annoying screw on the bottom of the unit that sticks out and grinds on whatever is mounted below it, in my case, the top of the other amp. It is THE screw that holds the heat sync to the case, nice. Solution was to countersink the screw a little, requiring a little drill and tap of the heat sync and minor deformation of the case (dent it in at the screw head) so that the screw head is now flush with the rest of the bottom of the case. Fans are NOISY, not very noticeable in a DJ situation, but since my rig substitutes as my computer gaming sound amp system (oh yeah it rocks!), the excessive fan noise required a little parts swap , no biggie. Quiet fans are pretty cheap. That being said, now they are mounted and running, they rock. They in no way match the specs in the website, but they do put out enough power to punch a couple of Rockville RSG 12.4 speakers and a pair of Rockville SBG1128 woofers well enough to make sufficient sound levels for "recreational" level DJ-ing. Paying gigs would require more serious gear, but for what I spent on it all, it is quite sufficient. In spite of their shortcomings, they pack a fair bit of power for the buck so I'll likely pick up a couple more, eventually. Again, I have been fortunate enough to not have experienced any reliability issues. These amps just keep running.

The amp is very nice. My fans are quiet at my power level. In fact, my computer fans are louder; perhaps after running with more power and heat they will kick-in. Construction is very nice. I do not believe the power rating stated (peak or rms).... I believe it is less, but without testing it......nevertheless, this amp is terrific. Clean, great sound for the price and works very well with my OSD Audio Pre-1 mixer / preamp. My speakers are home-made. Running (2) 8" woofers (low freq woofer and a low-mid woofer), a Bema horn from France when they were available.... running with my JBL 2445J , which is a 2446 Compression Mid Driver (16 ohm), and running a bullet tweeter. Crossovers are home made using 12GA wire (yes, very big and will never burn out). Anyway, I have only been using this amp for a few days but no regrets. In the future I will probably order 2 more of these amps to allow for 5.1 system, but still allow me to run 1 amp for 2ch music. To me, running the 5.1 / 7.1 / 9x /11x system never sound the same for listening to simple music on 2 channels. Many of the new and former stereo's over the past 20 years with all their "sound effects" do not support adequate current to drive speakers. They put too much of the special effects garbage (like toilet bowl, bedroom, auditorium, etc.... sound effects which are useless to me) and they could have made a better amp section. I also love Mac amps but could not afford at this time - maybe later. In the mean time I am happy with it. I will update as time goes on.

So coming from a self proclaimed (and friends and family too) audio snob, I can honestly say the Rockville RPA9 is a pretty decent amp. I’ve had it running in my home setup for three days and can honestly say this amp has great sound. All in all I’m pretty happy with it. I’m a collector of fine vintage speakers such as Cerwin Vega, Advent, DCM, Infinity and JBL all from the 80s and 90s. I strongly prefer Crown A/B amplifiers but wanted to give the RPA9 a try. Here’s what I think: Pros: It’s an A/B amp which I prefer to Class D. Class D just sounds so empty and flat. Which is a good thing because you can EQ the sound to your liking. But I enjoy the full bodied warm sound of AB. There is zero noise. Meaning no hiss or hun coming from the speakers when idle or under load For an AB amp it’s very light Connections are easy to get to and manipulate Operationally it’s quiet. The dual fans don’t bother me Both channels seemingly have equal power output. One does not seem to have more output than the other. My ears are trained for this. XLR balanced inputs and outputs to connect more amps if you desire. Cons: The power supply and transformer are very small. This amp will not give you outdoor concert levels. I believe when this amp has its gain knobs all the way up you are truly using all of its power. There’s no extra headroom. The paint work on mine is full of flaws. The power cord is really small. I’m talking 14 gauge with no built in filter. All in all this isn’t a horrible amp and I do recommend it if you’re looking for an inexpensive amp for your vintage speakers. At its price point and what I’m using it for, I’ll be keeping it inside the rack happily. It will power my Cerwin Vega D2s without any problems.

I bought my first stereo in 1972 when I was 16. Became an "audiophile" in my 50's and have bought and sold enough stereo equipment to buy a small house. I recently had to have my vintage Phase Linear 700b amp repaired (vintage gear needs maintenance). This amp and my McIntosh 2270 amp are the nicest sounding amps I have ever owned (for different reasons) I needed a quick back up for a few months until the 700b could be repaired. My vintage AR9's are 4 ohm speakers and require Lots of Power. The RPA9 actually sounds very nice! Being a rock drummer for over 40 years you know PA gear and some amps will handle 4 ohm loads very well. The super inexpensive amp is doing a great job plus it's also pushing (4) 12" woofers! My two other home audio amps are the price of a used car and this amp was about $150 so it is a great buy and does a really nice job. Here's my comparison: A 92' Corvette LT1 is 300 hp, A Dodge HellCat Challenger is 707 hp. BOTH are powerful but different. No need to diss this amp so much. It sounds very good, especially for the amazing price. Very happy as a back-up amp and will keep it for other stuff when the Phase Linear comes back from the shop. Lots of experience means everything people.

Writing a new review on this because last one was little harsh. These are good amps for driving passive subwoofer. But! Now that ive figured out the input sentivity on the amp is horrible. You need buy a line level voltage booster to get the rated power from this amp. That being said I submitted a return on the amp because before I added the booster this amp was barely audible even bridged. Now it preforms exactly how I hoped it was would according to rated specs. Its a great amp but you absolutely need a line level booster to get it to work like advertised. Honestly they should have that listed so people dont return them like I almost did.

Has a high rooftop power peak that maintains music clairity in high volume enviroments. Setting up a new DJ music system went smoothly witout issues.

Im very pleased with the results of this amp. Both 15" cabinets POUND. I don't run a sub (I don't have one yet) but the amp can do 2 speakers and a sub with Xover support. or run 4 speakers without a sub. Simple to use amp.. The fans are loud.. but when you have music on.. YOU WILL NEVER HEAR THEM. so it doesn't matter. but in a studio where its supposed to be quiet... its the loudest thing in the room. hah. don't let that scare you.. its a great amp.. pay more for a quiet amp if you prefer.. but the price was decent.... Oh yeah, doesn't seem to run hot..... Amp is cool to the touch.. Fans move a ton of air.. Without my pre-amp I Set the gain at 2-3 'o' Clock.. (fairly high) but not maxed out.. Far from it and that's good... now with a pre-amp the gains are at 10-11 and it varies how i setup my pre-amp. great volumes ! either way...

not expected 120volts, it should be mention on brochure

Amazing amp. Drives my 18” subwoofer bass bin exquisitely or put differently it rocks the bass big time. It’s driving a 3000watt peak woofer that kicks ass with the Rockville set at mono bridged!! I love it!!! Excellent value!!! Thinking of buying another one in the new year!!

Do not let the 4 stars fool you it's not a bad product but could be with some missing and cheaply added features. Cons : -The parts are common stock power amp parts nothing special about them - There is no way to control the dual fans speed ( pots should be mandatory on the back of these devices). So it's loud so no way to use this in a studio for close to the Mixing desk. -Can not be used for home theatre use unless its hidden in sound proof closet see above. - The power rating at 8 ohms ( 175x 175 at best ) is nowhere near their rating. Inside the Unit there is not enough Caps to pull the wattage they state ( 2 caps is not going to pull 1200 watts). Pros : -It is built and assembled with good quality -Excellent packaging ( box within main box) - Front Handles!!!! 😂😂😂😂 - The back of the unit has tons of connection options this is where this unit even has an advantage over double the price ones. - Clean Sound so this unit does no colour your tone ( very good!!) - Good sized Toroid Transformer so you have some options later on to add some features to this amp. -Direct Outs.... this is a no brainier yet many expensive units do not have these outs!! Overall you may spend less building your own power amp but this unit to me is an excellent starting point due to its price and build. Issues that you may want to fix ( this is on you, you are responsible for what you do yourself) 1. Fan noise issue 2. Holes for mounting on rack are slightly off 3. Remove handles if you want a more clean rack front 4. Remove the feet of the unit so it fits in rack easier After using it for a week I am okay with it and happy with what it does. Note : The stated wattage of 1000+ watts may be less with the gear you are using.

Works well
