Pyle Home Audio Power Amplifier System - 2x40W Dual Channel Mini Theater Power Stereo Sound Receiver Box w/ USB, RCA, AUX, LED, Remote, 12V Adapter - For Speaker, iPhone, Studio Use

Great value for a small room. We have an older Pyle mini-amp downstairs which powers a pair of speakers in our kitchen. It has worked flawlessly for over 3 years, so I figured I'd give this little guy a shot. My daughter wanted a better sounding system for her bedroom, so I built her a pair of speakers using MarkAudio CHR-70A drivers. Paired with this amp, I think it is almost impossible to find a better sounding system for such a modest amount of money. As for the amp itself, she has had no problems with it. It has plenty of power for a bedroom system, even using the aforementioned drivers, which have a relatively low 85.4 db sensitivity. More sensitive drivers could go louder with the same amp. The sound is nice and clean, with no audible distortion until you really crank the volume up high, which she doesn't do anyway. Played at normal listening levels, the sound is great.Love the fact that it takes a USB thumb drive. For those who may not be familiar with this feature, you simply copy MP3 or WMA files to a thumb drive, then plug the drive into this amp and it will decode and play them. Super convenient and it sounds great. We have not had any problems with any files not playing. It has worked great so far.A note about the remote - it's a cheesy generic model, but it works. I don't think Pyle makes the remote - they probably buy it from some el cheapo Chinese manufacturer. Regardless, it works OK for basic functionality. You can punch in, for example, 14, and it will go to the 14th song on the USB stick, which is kinda nice. It works for volume too, but the volume knob on the amp itself is not motorized. So what this means is that the knob on the amp is sort of a MAXIMUM. The remote can reduce the volume below what the knob is set at, but it cannot increase it. Fair enough. She just sets the knob permanently at about the 12 o'clock position and then adjusts down with the remote.The aux input works great with her iPod. So basically, this is the perfect little amp for a kid's bedroom, or for an office, den, or any other smaller room. Sounds great, loud enough for most people's tastes, and has been reliable so far. I did have some concerns about long term reliability, but noticed that Amazon is offering 3 years extended warranty for four bucks or something like that. Pocket change for 3 years peace of mind. If it breaks, we'll just send it back under the extended warranty.

I bought this just for the amp to use as a booster for a frequency generator in vibration analysis. I hook it up to my Android phone with a frequency generator or to my Siglent arbitrary waveform generator; works great. Run into a sub-woofer can REALLY create some vibration! To my pleasant surprise, it also has a stereo FM radio; nice! Use it as a radio too! Excellent quality of knobs and switches. Might buy another just for my kitchen. Three stars on the remote only because I didn't use it.

While I did have to return/replace the first unit due to faulty LCD segments and properly secure the fuse on the second one, it is a useful device with good features for the price.While I have not tried/tested the RCA or SD inputs, I have a test environment that includes a phone connection (Bluetooth), USB Thumb Drive, Music Player (Aux), and FM radio.It would be nice if I could disable the "audible cues" for entering BT mode. It was nice to have the "Strong FM Signal" preset search but would like to "erase" unwanted presets. I am not 100% sure I like the automatic source switching to USB when you plug in a drive.The only part that irritates me is the blue Hi-brite LED Power On light...blinding!

This little amp is perfect for those of us who can't bear to part with our LPs and cassette tapes, but don't want to spend a lot on a replacement component system to play them with (my old Pioneer speakers are still in good shape but the other components were pretty much worn out). I connected this amp to my recently-acquired modestly-priced compact shelf system and those Pioneer speakers, and the difference is like night and day. And the amp is well-priced too!

The good:I bought one of these and it worked great - initially. I replaced an old Bluetooth module for my balcony speakers. The unit paired seamlessly with my phone. First time I selected FM it seemed to automatically program all teh p[resets, and it easily picked up my local FM stations without an antenna - more on that in a minute. The audio quality was decent, not outstanding, but probably worth the USD $40 for the combined Bluetooth, FM, and amp functions.The badAs noted, the sound quality isn't great. However the speaker output connections are horrible. Both positive connections broke while repositioning the unit its shelf. The spring-loaded clamps popped out. It is important to note they didn't break, they just popped out. I was was able to reseat them, but the slightest movement of the unit would cause them to pop out again. So I returned this unit and ordered ar replacement. The new unit won't program for FM, and there is no documentation on how to trigger programming manually. The FM 'antenna' provided doesn't fit the plug, nor does any normal FM antenna connector (I do a lot of stereo work and had several on hand). I've posted questions and I;ll update if I get answers.ConclusionPyle products seem to be a mixed bag in terms of quality. I have had multiple Pyle amps. I had a phono pre-amp that worked fine until I retired it (about 5-6 years). I had a small amp for my patio that failed after about 16 months. However the larger, more capable Pyle amp with which I replaced it has been going strong for three years now.I really like the combined functions of this unit, and it does what I need it to do at a price point I can accept. However if the replacement turns out to be as fragile and can't execute it's basic functions consistently I'm going to keep looking - and the review will drop accordingly.
