Review on Pyle PT694BT: 5.2-Channel Hi-Fi Bluetooth Stereo Amplifier - Powerful 1000 Watt AV Home Speaker Subwoofer Sound Receiver with Radio, USB, RCA, HDMI & More - Ideal for 4K UHD TV, 3D, Blu-Ray by Francisco Duncan

I've been trying for hours to connect it to my 5.1 surround sound system to no avail. I have the best audio engineer I've known in 45 years. He drove to my house (two hours away) to do it for me and gave up after a few hours, eventually giving in too. And by the way, it has a blue light that dazzles in front of the receiver that flashes when it's off, totally stupid. Very bad design and it doesn't work. The best thing about this POS is Revain's return policy, which is second to none when shopping online.
