Home Audio Power Amplifier System - 2X120W Mini Dual Channel Mixer Sound Stereo Receiver Box w/ RCA, AUX, Mic Input - For Amplified Speakers, PA, CD Player, Theater, Studio Use - Pyle PTA4 Black

This is a great little stereo amplifier with 3 RCA inputs for Aux 1, Aux2 and CD. There's also a high impedance microphone input (1/4" jack) and a spare Aux input (1/8" jack) on the front panel. The front panel controls are Input Select, Balance, Treble, Bass, Master Volume and a mic input level volume. Outputs are L & R speaker terminals, Record out (flat) and Phones. There are switches for Mixing the mic with main program material, a Pager setting for the mic, a On/Off power switch and a voltage selector (110/240). It's very well built, solid and looks high quality. Listening tests on quality speakers (JR149s) plus passive sub woofer sounds to me exactly as good as my normal home HiFi on different types of program material. It's subjective but honestly, I couldn't tell the difference so sounds great. Now for some technical stuff. As I have a digital scope & a sig generator I measured the frequency response into a resistive load (8 ohms) and it was as advertised (in linear region ie: no distortion). I ran a 1KHz square wave at several different levels (short of clipping) and the unit showed no signs of ringing or instability which is very good. Then for the not so good..... The unit is advertised as being able to source 2 x 120 watts into a 4 ohm load. My measurements showed using a 200Hz and 1KHz sine wave that just below the onset of clipping it would provide 18.4v peak into 8 ohms and 15.2v peak into 4 ohms which translates into 21 watts RMS into 8 ohms and 29 watts RMS into 4 ohms per channel. So in reality my unit provides 2x30 RMS watts into 4 ohm and NOT the 2x120 watts as advertised. Some manufacturers provide misleading power info by advertising PEAK instantaneous output power without stating that it's not true RMS power which is the only power that counts. Peak power divided by 4 equates to RMS power. You can't really say it's dishonest advertising so buyer beware!! So in summary, this is a superb high quality and versatile home stereo amp at an incredible price. Mine provides 21 watts RMS per channel into 8 ohms (which most home speakers are) and should provide years of listening pleasure at reasonable volumes.

I was pleasantly surprised with the quality of this unit. Instructions were good and set up was easy. The controls allow for good sound adjustment for perfection settings. Highly recommend.

Details to my music system: My house has ceiling speakers in every room for background music. For several years it has been running on a low-end home theater system rated at 30 watts per channel @ 4-ohms; Music provided by its over-the-air FM stereo function. It works well but it's time to upgrade to a more advanced solution that has internet capabilities. For example, internet radio access and media playback from my NAS drive. So I DiY assembled a media player using a Raspberry Pi micro computer, Volumio software, and a HiFi I2S DAC board (total cost about $90). This needs a power amp and the specs for the Pyle PTA4 looked like a good choice. Start of Product Review: To my surprise I found a Pyle PTAU45 unit inside the factory sealed PTA4 box. For some mysterious reason I received the upgraded model with USB media port (which I don't need). Since all the important specifications are the same, I decided to keep it. Here's what I found inside the box: Pyle MINI 2X120 WATT STEREO POWER (PTAU45) The metal cased amplifier is small and attractive, but surprisingly heavy. Its beefy weight is because the amplifier has an old-school linear power supply instead of a modern switching supply. That's not a bad thing, just an explanation for the heavy weight. Installation was easy, but I encountered a small problem. During speaker wire installation one of the spring loaded jacks fell apart (this issue has been reported in other reviews). I reassembled the jack and finished the installation. Sound quality is good. But the maximum distortion-free audio level is dramatically less than my previous amp, which was rated at 30W per channel (RMS). As others have observed, there's no way that the Pyle amp has 120W per channel. Based on my observed results I think 25W RMS per channel is more realistic. Overall I am satisfied with the Pyle amp. It was the final piece needed to create my new music system. Now my home has internet radio, a NAS music server with hundreds of my albums, smartphone control, and a compact sized amplifier box. The best part is that the overall cost was amazingly low. BTW, if you are interested in making your own internet capable media player then here's a summary of the parts needed: Raspberry Pi 3 Model B+: ELEMENT Element14 Raspberry Pi 3 B+ Motherboard HiFi I2S DAC: SainSmart HIFI DAC Audio Sound Card Module I2S interface for Raspberry pi B+ 2 Software: Search the web for Volumio Audiophile Music Player Misc Parts: SD card, 5V/2.5A USB Power Supply, suitable case, etc. (typical Raspberry Pi Project parts). Review Summary: Pros: Low cost, compact size. Cons: Speaker clips are fragile. Output Watts much less than stated.

This is my second Pyle amplifier, and for good reason. I bought my first one—the PTA3 2x75W—back in 2010, and after 15 years of powering my outdoor speakers, it finally gave out. These days it’s rare for any electronic device to last more than a couple of years, so I was genuinely impressed that it made it that long. I’m the type of shopper who obsessively researches every available option before making a purchase, no matter the price. Initially, I tried one of the newer amplifier brands that showed up in my search results and had solid reviews. But after hooking it up, I was extremely disappointed with the power output. To get decent sound from this new Class D amp, I had to max out the volume on my source device (an Amazon Echo). That meant I lost the ability to tell Alexa to turn the volume up, because it had to stay at 100% just to get acceptable audio levels. After more research, I realized that input sensitivity is a major factor with these newer mini‑amps. To make that other amp viable, I would have needed to buy a separate pre‑amp just to boost the signal. Instead, I checked the specs on the Pyle PTA4 and saw that its input sensitivity is 250 mV—meaning it requires only a quarter of the signal strength to drive the amplifier properly. Once I hooked it up, I was pleasantly surprised. It sounds fantastic even with much lower volume coming from my Echo Dot. I can now leave the main amplifier volume at 50% and adjust everything directly through the Alexa app without ever touching the amp. The sound is rich and warm, unlike the other amp, which felt tinny and lacking depth. Plus, the PTA4 includes Bluetooth—something my old PTA3 didn’t have—so connecting any device wirelessly is effortless. This is going to be a great upgrade for my patio speakers. Here’s hoping I get another 15 years out of Pyle’s solid, reliable products.

This is actually the second unit I bought. I returned the first one because of a loud whine/hum for about 12 seconds after it was turned on. I tried again because I really wanted to like this amp. I needed a mini amplifier with a headphone output, and there are not many in this price range that have one. Because of this, I decided to give it a second chance, figuring I just got a bad one the first time. This turned out to be correct in a way, because the second unit didn't have the same fault as the first one. Unfortunately, it had a different fault; this time it was a constant hum that was way too loud to ignore. The hum was always present no matter what level the volume was set at, and no matter what input was selected (including Bluetooth) It's such a pity, because, on paper, this amp was exactly what I needed. It's a nice looking unit too; the steel chassis is good quality, and the unit feels solid and robust. I don't know whether it's an inherently bad design, or if it's just low quality parts and/or poor QC, but after two bad ones in a row, I can't recommend this amplifier. If, like me, you are looking at this amp because you need a speaker amp that also has a headphone output, I don't know what to tell you. This amp has a headphone jack because it's a Class AB amp, which makes adding a headphone output relatively trivial. Most mini amps today are Class D, and typically use a BTL design, which makes adding a headphone output more difficult. Most manufacturers don't bother because it adds expense and complexity. They do exist (like the Nobsound NS-20G and the Moregax M19 BT) but they all seem to have some sort of drawback. I ended up buying a used Topping amp.

After searching around extensively for a simple yet quality receiver that met my needs, I confidently purchased this product. I needed ample wattage to handle my Klipsch R-51 as well as an input on the front of the device for my iPad so to play music, etc from it. Lastly I needed it to take my audio mixer, a dvd/cd player and a tv — all of which it does very well! I’m totally satisfied with the quality of the build — it’s a hefty little piece and the knobs/dials and inputs are solid and securely manufactured. If you’re wondering if this receiver has what it takes to power up a pair of Klipsch R-51’s or the like, then look no further! Plenty of headroom on the volume and plus there’s room to spare to dynamically dial in your highs, mids and lows. Even though it doesn’t come with a remote, it serves my purposes well. My only issue is that upon delivery, the box clearly indicates it is a stereo receiver (diagram included), making it a bit of a tempting grab if you’re in an apartment building, condo, etc. and worry your deliveries might fall into the wrong hands. So, I’d suggest upon purchasing, try to request that the product is shipped within a standard Amazon box so to hide the contents of the delivery.

Bought PTA4. Nice compact unit. Looks quite nice. Functions with ease. I bought it to power two floor speakers either at site or remotely by Bluetooth. The receiver doesn’t seem to like my remote Bluetooth. But my add on Micus RTX overcomes the issue. I highly recommend the PTA4.

I like the size, the price and the styling. Less wonderful things include: There are bright blue led lights that flash when it's in use (obnoxious) which I covered with black electrical tape. The power of the unit when it pushes my 8 ohm Altec Lansing bookshelf speakers is less than I would have thought, given the power rating (it doesn't seem like they're getting anywhere near to 60 watts of clean power per channel - to me anyway). The tone is really only average with a bit of muddiness in the mid and a lack of sparkle in the upper ranges. But what should I expect for $75? For that price, I'm sure you can't beat 'em and for my application they work OK.
