Review on 🎧 Pyle PT390AU Home Audio Power Amplifier: 300W 4 Channel Theater Power Stereo Sound Receiver Box with USB, RCA, AUX, Mic w/ Echo, LED, Remote – Ideal for Speaker, iPhone, PA, Studio Use by Shakira Anderson

Works in my garage with all 4 channels. Sounds great, very loud. It would be nice if only a few things were changed or added. The power switch is just a button, it cannot be turned on or off with the remote control. Not the end of the world, but weird that it can be radio controlled with any function other than this. When you turn it on, the volume automatically gets pretty high. High enough that no audio should pass through until you turn the device on. This is programming to be decided by the manufacturer. The volume steps are too large. It would be nice to have more space for variable volumes. Each volume/volume control step is represented by step 2. Using volume 08 is hard to hear, 10 is a bit loud, 12 is too loud through the aux inputs. Looks like another thing that can be fixed with a programming adjustment.
