Review on 🎵 Pyle Bluetooth Mini Blue Series Home Audio Amplifier - Compact Desktop Home Theater-Stereo Amplifier Receiver with USB Charge Port - Pager & Mixer Karaoke Modes - Mic Input (40 Watt x 2) - PTA22BT: The Perfect Amplifier for Home Audio and Karaoke Entertainment by Angela Patra

My new 'expensive' 7.1, 4 HDMI input 'box' didn't support my current B-channel speaker system so I needed another amp to match it Getting sound where I wanted it. This Pyle amp did just that. (I didn't need Bluetooth functionality.) It had volume, balance, bass, and treble controls, and the sounds were very good. I used two of the three inputs, one from my HD radio and the other from my CD changer. Ideal. But I couldn't figure out why the RCA audio out wasn't working. Apparently the output level is controlled by the speaker's volume control. That is in a nutshell "BUT". This feature "? Is this an internal wiring problem? One day I'll get the schematic and find out.
