Pyle Compact Mini Public Address Amplifier - 50W Home Power Audio Sound PA Receiver System w/ AUX,2 Microphone Inputs,Independent Volume Control,Power Cable,For 4 to 8ohm Speakers - Pyle PMSA20 Black

Excellent PA system for the price, I tried it out with our present microphone for Mark whole system and it works perfect. I plug my iPhone into the auxiliary port and it plays music on my iPhone perfectly. This is a great PA system at a very reasonable price with fast delivery.

I rated the unit at 4 stars. The amplifier works but does not achieve the volume I expected or was hoping for.

This little amplifier exceeded my expectations. Though the literature was the usual skimpy confusing translation, it is a very simple device that needs only to be connected to a microphone and speaker(s). It fills the room with the speakers voice nicely. The room can hold 200 people. There is no hum or distortion at about 60% volume as installed in a podium with 2 built-in small speakers. Pleasantly surprised with the excellent price and quick shipment.

This little amp (it's not a "power amp" as its manual says but an integrated PA amp) would be fine except for its poor signal-to-noise ratio. It hums, relatively loudly, which is a shame as it works pretty well, otherwise, and actually seems to put out around 50 watts, as advertised. Since there are so few other reviews of the amp, I'm not sure whether I received a defective unit or if they all hum. I might try exchanging it and, if I do, I'll update my review.

Making PA system from it for parties, announcements, karaoke. I am connecting it to a 3-way (12"-8"-2") speaker. AUX takes in 3.5 mm phone input with a stereo adapter, so I can feed music from my phone or MP3 player. Two MIC inputs: input from MIC1 tunes off AUX input when you speak while input from MIC2 mixes with AUX. So, use MIC1 for PA and parties and MIC2 for karaoke. A little hum from MIC1 and MIC2. The dB is not bad but could be louder.

Good choice if you simply need amplification at modest volumes. Handles mics and line level. Reduces the volume of the line level when you speak over the mic input. Just wish it had a 1/4-inch jack for the speaker connections.

This unit would have been perfect for my application. It's a small digital amplifier. However, it is not 50 watts RMS. It is, in fact, 8-10 watts into a perfect load. Still would have met my need. It sounds ok. The problem is that it generates almost as much radio frequency energy as it does sound. There is a solid 950 khz. coming out of the speaker terminals even into an 8 ohm load. That radio signal is amplitude modulated by any audio input. If I connected an antenna to the speaker terminals it could be a neighborhood broadcast station. There is no FCC type acceptance label on the unit or in the instruction manual. I suspect it is illegal to sell in the United States.

Works great
