After much research I decided to try the product and apply it to drive a Polk Audio RC80i 2-Way In-Ceiling speaker sound system with two in-wall volume controls installed by my builder, and pre-wired to a connection point tucked behind my 55" wall mounted flat-screen TV. The objective was to drive the set of ceiling mounted speakers through the MCM amplifier using my new Samsung TV as the audio source; and in short it worked like a charm! the unit is so small I easily attached it to the wall in the space available behind the TV and right next to the wall mounted set of coupler-type connection posts for the speakers provided by my builder. From there physically connecting the MCM 30 Watt Amp to the four binding posts of the Wall Plate took only a few inches of speaker wire. From there I had the option to connect the MCM to my TV via the 3.5 mm stereo audio line level input or via the MCM's built in Bluetooth receiver; I tried both and the result was the same; outstanding in all cases. In fact, the whole thing worked so well I purchased a second unit for use in powering ceiling mounted RC80i speakers installed in my great-room and dinning room areas, except this time the little MCM Amp would have to drive four RC80i's (2 sets of Polk RC80i speakers) mounted in the ceiling by my builder, and the source here will be an assortment of devices streaming music and other audio content to the MCM via Bluetooth; including our Amazon Alexa. Here too the tiny MCM proved an easy connection for each device I put forward and amplified the content beautifully. I call this piece of technology "the little giant"! I literally could not find a device for 3 times the price that could do everything this MCM 30 Watt Amplifier with Bluetooth Receiver can do.
