Pyle Wireless Bluetooth Power Amplifier System - 200W Dual Channel Sound Audio Stereo Receiver w/USB, SD, AUX, MIC w/Echo, Radio, LCD - Home Theater Entertainment via RCA, Studio Use - PDA6BU.6, Black

So the price is great. The sound, for a few minutes I heard it, was also great. However, here's a little story. I got the box, easy connection, sounds great. Walked to the next room and lost bluetooth connection. No problem, I'll just put it in a different location. Got it reconnected, sounded great for about three minutes, then I hear a crackle, and smoke starts coming from the receiver. OK, I'll call and get a replacement. It arrives, I hook it up and pair it to my phone. No smoke this time, but the Bluetooth is like I'm 30 feet away, dropping signal all over the place. Okay Amazon, thank you for processing my refund. Not going to try another Pyle device anytime in the future. 🤬🤬

Ordered this back in November and got it Christmas Eve 2022. This is actually a pretty nice receiver. I like the sturdy build quality, the compact size of the unit and how vivid/bright the LCD screen is. Having bluetooth is an awesome touch, because it saves you from having to go out and buy a Rocketfish/Logitech bluetooth audio adapter, etc.As indicated in my heading, there's a few weird quirks about this unit that I discovered which I feel people should know about:1) There are actually *two* ways to power the unit on and off. One is by using the power button on the unit itself, which is a hard power cutoff switch. If this button is in the OFF position, the entire receiver is completely turned off as you would expect-- no lights, no sound, no display on the LCD. But then there's a 2nd power button on the remote control, which acts completely different. If you turn the receiver off with the remote, the LCD screen stays lit but blanks out, and all the lights remain on. I've never seen a receiver do this, and I'm gonna guesstimate that it has to do with it just being a $50 receiver.2) There are two ways to increase/decrease the volume. One is via the knob, which works as you'd expect. But on the remote there's a volume up/down button. Since the knob doesn't have an infinite axis (in other words, there's a max and min range it will turn before it stops), you would think it should be motorized or something to sync with the remote. But again-- since this is a $50 receiver, you aren't getting a motorized knob. That would cost a lot more money to manufacture, LOL. I'm gonna play around with this a bit more and see how the volume is affected, etc.3) When you press the mode button, you'll notice the LCD rotating between different modes like Bluetooth, Radio, SD Card, and so on. However, the mode button only works on ONE of the 4 physical inputs, but the modes will actually display on the LCD regardless of what physical input you have selected. If you want to use any of those features, you have to have the small input knob physically turned to the one labeled "MP3/SD/BT", otherwise you'll get no sound.This quirk sent me in for a mental roller coaster, and it made me think the unit was dead for a while, because I was trying to listen to the radio (which was displaying on-screen), but the radio had NO SOUND whatsoever... So just be mindful of that, and if it looks like the radio is on but not producing any sound-- it's likely because you just have the receiver on the wrong physical input.Update 1/16/23:After playing around with this receiver a bit more, I discovered a few things:A) All the controls on the receiver will control everything as expected, no matter which input you’re using. Probably to avoid most confusion, I’ll be using mine this way and not even bother with the remote control.B) It looks like this receiver has some kind of internal digital computer, for handling the “MP3/SD/BT” input. This digital portion seems to have no idea that the AUX, DVD and CD inputs even exist, and it’s always on, until you press either the power button on the receiver itself (which will shut the entire receiver down), or the one on the remote. That would explain why there are two ways to power the receiver on and off, why the LCD is always showing “No Disk”, and why there are two volume controls. It also explains why the bass/treble/balance controls are NOT on the remote, and why the remote’s volume control doesn’t affect any of the other inputs. It also seems to be tethered to the silver buttons on the receiver and the LCD screen.C) The remote is ONLY for the internal digital unit mentioned above. So none of the inputs would work with it. Like other comments mentioned, it makes the remote a bit useless unless you’re primarily going to be using that MP3/BT input on the receiver.Anyway, that's it. Overall, it’s a pretty interesting unit and I had fun playing around with it and figuring it out. It’s a very strange machine, but it's definitely going to do what I need it to do, despite the odd functionality. For $50, it’s honestly not a bad deal. Hope this is helpful to others who want to buy it. :)

Id had this same receiver installed in my garage to listen to music while cleaning, brewing beer, or whatever else I was doing in the garage and it had performed perfectly until just last week. Turned it on, came on just fine, after 30 min or so lost the left channel and while attempting to diagnose the problem lost right channel as well. The little guy was no longer making a sound of any kind, amp was dead. Ordered the exact same model as a replacement during Amazon days for a slightly better price, amp arrived, plugged it in, waited the 3 hours for internal batteries to charge and found that the Bluetooth would not connect. Tried several things in an attempt to get it to pair up and was unsuccessful. It has been sent back and a new one ordered. If there are additional problems with the replacement unit I will amend this review. Until the old one crapped out after about five years I was very pleased with its performance. But, as they say, nothing lasts forever except the NBA season.As promised I am updating my review. The new one is here, installed and working perfectly. No complaints and have upgraded to five stars. This much receiver for this low a price is an unbelievable bargain. I highly recommend.
