Summary: I bought this amplifier to boost audio from Mp3 players and YouTube videos in our church's youth classroom. It works extremely well for both purposes. We get plenty of amplification without any distortion. The separate bass and treble controls are a huge bonus. My only negative comment would be the brightness of the blue lights could be distracting depending on where you place the amp. It's a perfect solution for our application.
Excerpt: I'm using it with a couple of old Bose Bookshelf speakers, in a 250 sf office. It won't crank really loud before distorting ( it seems more like a 2x 15w amp), and you'll want to make sure not to overdrive the input. However, at reasonable volumes it runs just fine, and both its size and price are very convenient.
Summary: ***THIS REVIEW IS SOLELY ON THE PRODUCT. IN NO WAY DOES IT REFLECT ON AMAZON'S EXCELLENT CUSTOMER SERVICE*** Distorted sound, even at low volumes. Used it for two hours to power two speakers at 50w each, at low volume. Kept indoors, A/C on and we'll ventilated. The next day tried to use and powered off immediately after turning on. Checked fuse and it was blown. Replaced fuse three times and blew each time. Not sure if I got a bad unit or that these things are junk.
Summary: I have been using this to drive my bathroom built in speakers for 2 years now. I push it to the end. works great. this will never be an audiophiles dream but when the water is running you cant hear the little bit of hum it has at top volume and no input. I would buy this amp again.
Excerpt: I am one week into using the PCA3 to powering my homemade Auratone Mixcubes for audio monitoring. The PCA3 is working great right out of the box! The front metering LEDs are unreasonably and obnoxiously bright, so unless you put this amplifier inside an opaque box, you'll most likely want to put some sort of tape over them to keep from injuring a retina or two.
Pros: Compact, Easy to Install, Great For Lofi Comparison
Excerpt: Purchased to use as replacement speaker amp for new , and expensive, TV that had marginal built in speakers. Hooked this amp to Mirage mini Nanos and a very inexpensive Earthquake Mini Me 8" subwoofer. Sound is quite good from the Nanos, marginal (boomy) from the sub (not the Pyle's fault!) and better than the TV speakers.
Summary: Properly ventilated and I didn't even run it that hard (maybe 7 or 8 tops on volume, but never maxed it out). It just quit working. Checked the fuse, all good. Power supply to the unit was good (red light was "red" after it quit)... it just stopped working without even using it for 2 or 3 hours. The irony is I read the Amazon reviews on this unit and that swayed me, so I don't expect my review to sway anyone one way or the other.
