Review on 🎤 Wireless Karaoke Bluetooth Stereo Receiver Pyle - 4 Channel Power Amplifier with USB, Headphone, 2 Microphone Inputs and Echo, Talkover for PA - Ideal for Home Speaker System - Model: PTA42BT by Andre Noel

I bought this to have a multi-zone setup for our garage, patio and pool. I figured four channels would be enough for this (2 channels in the garage for my 4 speakers, one channel for 2 speakers on the patio and one channel for 2 speakers by the pool). I've read reviews that say it's a MONO amp even though it's advertised as STEREO. My device was indeed stereophonic. it was a little weird. Each of the 4 channels is either left or right, although each channel has two sets of speaker connections. This means you can connect two left OR two right speakers to each channel. If you want stereo in a specific location, you must use 2 channels for that location. Obviously this isn't working for me so I went back. I ended up getting the zone selector and amp as separate units for a little more money. One thing to note related to the quality control of these devices: the left channel and right channel were oppositely marked on the labels. the back of the device is displayed. Images of this article do not show any left or right side markers at all, but my unit had left and right side markers. They were simply upside down from what the label said. This leads me to believe that some of these devices are connected in one way while others might be connected in a different way. the input has been swapped or incorrectly connected. However, the unit worked and sounded pretty good and is nice to look at, hence it gets a 3 out of 5.
