Pyle 420W 5.1 Channel Bluetooth Power Amplifier System

I was looking for a cheap 5.1 receiver. Well, I should have been careful about what I wished for. This is NOT a 5.1 Home Theater Receiver, this is nothing more than a Karaoke machine that happens to be able to do 5.1 (and doesn't do either very well).I tried one, returned it because the 5.1 wasn't working even when using 5.1 media. Replacement did do 5.1 surround (poorly). Returned after a single day of use, and I bought a Denon AVR-S540BT as a replacement. Save yourself the aggravation and get a real Audio/visual receiver.Let's be real, you don't care about my story, you are here for the facts:1) The HDMI Input *will* do 5.1, but ONLY if the input is providing 5.1 media. Otherwise you get Stereo only (no bass speaker).2) You can not force/upmix HDMI, Radio, Aux or Bluetooth stereo into 2.1, 3.1 or 5.1. If the input is stereo, you only get stereo. This means for Bluetooth and AM/FM radio, you will not get 5.1 sound, ever and only get 5.1 if you have Aux or HDMI inputs which are sending a 5.1 signal.3) There is no "Listening Mode", "Sound Mode", "MultiChannel Stereo", or "All-Mode Stereo". Meaning you don't get to listen to music on all the speakers. If you connect your PS4/PS5 or XBOX to this, make sure the game or movie/show you are watching is broadcast in 5.1.4) Does not do any Dolby processing or decoding and no ARC on this. The 5.1 processing is passable at best. If you play any Dolby 5.1 type audio, prepare for distortion, crackling and sound 'fluttering'.5) The receiver must be physically on for the HDMI passthrough to work (physical power button pushed in).6) When the receiver is on, the fan is always running7) Power button on remote puts the Receiver into standby, does not turn it off.8) No matter what volume level you have the speakers set to and no matter if you are playing Stereo, 2.1, 3.1 or 5.1, a slight buzzing/humming will be played on your speakers.9) Mic inputs were unreliable. I tried a few different mics in all 3 of the mic inputs, adjusted the mic level, adjusted the volume, adjusted the echo and delay. Mic was either muted or breaking up or highly distorted. Mics themselves work fine on other devices.10) AM/FM reception is absolutely horrid. I have a 1990's clock radio that can pick up better FM radio and my 1930's Tube Radio picks up AM better!
