Bluetooth 5.0 Stereo Audio Amplifier Receiver - 4 Channel, 440W Peak Power Home Theater USB, 🔊 SD, FM - 2 Mic in Echo, RCA, LED - Speaker Selector for Studio, Home - MAMP5 Review

I bought this amp from Donner for my office computer. It's amazing value and has more power than I've ever used. I use 4 Cambridge speakers and it can handle more if someone feels the need to expand it. The tone controls are precise and each channel has its own volume control. . What offer!

I was happy to receive this receiver for three days but was disappointed when I plugged it in and it made a loud fan noise when playing audio through the speakers. Also, the VHF antenna didn't have proper connectors (I had a used one) and the RCA connectors on the back were loose and cheaply made. Didn't try the Bluetooth connection as I quickly packed it up and sent it back the next day. Very happy with Revain's return policy. Went to a local store and bought a basic two channel Yamaha…

The Donner amplifier was defective by default. As soon as I started using it, there was a strange noise in the background. Confusing. It wasn't in the audio. It was the amp's fan going on and off. It was loud enough to be annoying, especially when it turned on and off on up and down ramps. It was almost comical because the harder the amp got - when the full score was playing - more amps burned - the louder the fan got. A fan tried to keep up with the music! Funny but annoying. Send back.

The device is ideal for decorating areas inside or outside the home. I bought it for an outdoor setup and it works great. We currently have two areas of outdoor foosball speakers, some of which are more than 75 feet from the receiver, and power is not an issue. Bluetooth connection with our iPad was quick and easy. 4 separate volume controls, separate bass and treble controls make it very enjoyable. I haven't used a USB or SD card yet, but don't expect any problems with it. Very reliable…

This unit works as shown. Used to drive 2 indoor Klipsch wall/shelf speakers on "Channel A" and 2 outdoor Bose speakers on "Channel B". Its performance is more than sufficient for the simultaneous operation of all four loudspeakers. Each pair of speakers can be set to different power levels. The power level is retained when switched off and on again. For the price (even if the price was higher) to ask for more and nothing. I bought it despite the first reviewer calling this device "junk" and…

I used it to control my new Polk Audio Atrium 6 outdoor speakers. Gives great sound. Not too high bass but overall great sound for a light evening. The volume can be very loud with clear tones, no distortion. The only thing I didn't like was the Bluetooth range of about 15 feet and with my iPhone 12pro I started to hear crackling in the noise. I just bought another BT adapter with a longer 25ft RCA to 3.5mm cable and now I can use my phone in my backyard and still enjoy clear music. For the…

I bought this for our pool with external speakers. For the price it's pretty good value but I can't figure out how to select the FM channel. I can't stop it when it hits a channel when I use auto select, and the manual button returns to the first channel when I switch to higher numbered channels. Also, I'm not a fan of the automatic favorites feature. It picks every channel it can tune into and I'm obviously not listening to every channel. I usually listen to 2 to 3 channels and add them to my…

I was skeptical about buying an unknown brand with no feedback or questions. I wanted a stereo for the patio. Bought 1 pair of Polk Atrium 4s and 2 pairs of Klipsch KHO-7s for a total of 6 speakers with room for two more. Absolutely delighted with the stereo. Although 440 watts are specified, this is not the case. However, this is certainly enough to ensure the sound quality of these speakers. In fact, it has more options than I can use without sharing music with neighbors, but I'm on a 2-3…
