4-Channel Audio Amplifier with Bluetooth - Home Stereo Receiver w/ 500W Max Power - Commercial or Karaoke - Dual Mic Input with Echo, Vol, Talk-Over - AUX In - Sub Out - USB-A MP3 Player, AM/FM

This was just what I was looking for. The 4-channel output matched the speaker set-up I pre-wired when I built my office space years ago. I was using a 4-channel speaker selector switch with two prior stereo receivers that eventually died. Tremendous feature set for the price and the unit is a very solid substantial piece of gear. The Bluetooth (a game changer compared to the old equipment) was easy to pair with my iPhone. I the FM radio section was surprisingly sensitive and picked up many stations with the included basic mono-wire antennae. I only listen to one FM station, so fortunately the previously tuned station stays tuned when the input mode changes. The volume could be way louder than my needs and sound quality was fine. One review mentioned, tight, not smooth volume control knobs of channels A B C D. I noticed that on a couple of mine but noticed that the knobs were pushed on a bit too much and contacting the face of the unit. Pulling the knobs outward (as if to remove them) fixed that and the smooth rotation of each knob was realized. I was curious as to the energy used so I measured the watts with a meter. As expected, the watts varied with volume: Plenty loud was around 30w, with ~20w for normal low background music. "Cranked" was close to 100w and probably unpleasant for most. A more energy efficient replacement in my situation.

Bought this for a shop radio, and it works just as it should. With AM/FM choice and Bluetooth everyone can use it. Outputs sound good enough for what i use it for, and the price was another selling point. I know this can do a lot more the what i use it for, so better it does and not need, then having something that doesn't do enough.

I waited to review this PTA44BT (4 channels) because I was somewhat skeptical (After all, this is a great price for what you're getting). WELL, you get what you pay for and sometimes you eat the bear or the bear eats you. I've been DJing for over 30 years, so I'm not stranger to the audio industry. If you research the reviews, most are made within a few months of the purchase (which is why you get a high amount of 4 & 5 stars. I, on the hand, waited to give my review because I've learned through experience that ANY electronic unit only can by measured by time (no unit sounds good if it doesn't work). My setup was simple... I was using bluetooth with Alexa to play music to my speakers in the livingroom (3 channels and the sub were connected). This unit initially worked exceptional and the added mic inputs were real nice. But, that didn't last long. I began to have some problems about a 1 1/2 year into ownership. Strange hissing noises began to come from the speakers when no music was playing. Usually, it's a sign of interference and your speaker wires not insulated well enough. Because of my background in music, I can eliminate this as the problem. Also, sometimes interference can occur within your power connection, this was also not the case. This noise began to occur more and more often and the music began to sound somewhat distorted. Others didn't notice the difference, but I knew for certain something was wrong. However, it didn't bother anyone else... so I ignored it. Slowly it began to occur more and more until I began to second guess myself and changed ALL the wires and made sure nothing else was plugged into that circuit. Still, it got worse until yesterday when the unit itself began to screech and no sound other than the sub was playing. This is a sign that the channels are blown. I looked into the unit and the fan had stop working. ANY electronics create heat and sensitive electronics hates heat. Fans are the conventional way to cool them down. Now, I know this wasn't the fan which started the problems, but it was the fan that ended the problems. My advice is to spend more money a get a quality amp for your application. I do not recommend this product!

Bought this to replace another amplifier that I had been using to power outdoor speakers for my pool and patio area. I liked that this was a simple amplifier as I didn't need multi-channel Dolby Atmos to play music and TV audio for my backyard. Overall, it will serve, particularly for this price, but it does have some limitations. Stereo - First, it's quite true as other have noted - this doesn't not send out a stereo signal. I specifically tested with sources that pan between left and right channels. The same sound came out of both speakers, even when the source was coming from only one side. While this is good enough for my needs, it is definitely misleading on the part of Pyle to indicate that this is a stereo amplifier. At least is seems to blend the left and right together into a common mono output, as opposed to just ignoring one of the channels completely. Bluetooth - The bluetooth function connects, but requires excessive hand holding. The bluetooth connection is pretty much the only one I was interested in as my patio TV has a bluetooth output and I was using a small bluetooth receiver with my old amplifier to send the signal. This new unit will connect and receive...but it won't remember the input setting. The manual indicates that you have to select MODE a couple of time to get back to bluetooth as it defaults to one of the other inputs when it powers up. I ended up using the other bluetooth transmitter hooked up to one of the line inputs on the receiver as I did with the old unit. So, the bluetooth function built into this unit proved largely useless to me. Power - I expected, having to only drive two channels and it being able to drive up to four pairs of speakers, that the two sets of speakers would not have any issues. Again, this proved to not be the case. With two sets of speakers running, I've had to turn the master volume all the way up, as well as the volumes knobs for the two sets of speakers that I've hooked up. The sound is adequate, but not nearly as loud as I would have expected given the rated power of the unit. When I first tested it with a single set of speakers, it did seem suitably loud. However in my final configuration it doesn't put out the kind of power I would have expected. I can't imagine trying to actually drive four pairs of speakers with this. On the positive side, the power button is a physical switch. I was able to plug it into an Alexa smart plug so I can power the unit on or off with a voice command. I prefer this as the unit is outdoors under a covered patio and the smart plug allows me to keep the amplifier from seeing any power when I'm not using it. Ultimately, it will do what I need it to do well enough. At this price point it was a reasonable deal.

Good ample, fire.If you have a wireless adapter, windows might want, you might want to use a sound card and go through RC.A jacks

Cumplió ampliamente con mis expectativas, necesidades y gustos. Buen diseño y funcionamieto

Finally my Pioneer speakers work perfectly with this PTA44BT amplifier. The delivery is very fast!!! Thanks a lot!

I bought this for my 4 ceiling speakers. no issues so far, works perfectly. Sounds great. Highly recommended

Good blasting sound quality! Easy to tune to your preferred sound quality via bass and treble control.

Due to some defect like channel knob also prodect is heated in short play so I requested to return back and make my refund in my account. Pay latter thanks
