“Where is the amplifier? I’m pretty sure amplifier and wireless receiver are not the same thing. The instructions are very vague and “what’s in the box” is tiny icons with no words.”

Just hooked this up yesterday; the 2 rear speakers connect via speaker wire to a receiver (not an amp). The receiver plugs into an outlet, then it connects to the soundbar wireless from the back of the room. The instructions in the box have 1 for the soundbar & woofer and then another for the rear speakers/receiver, it's an easy hookup all around, much better than just a soundbar & subwoofer. Here's the web page for LG: http://www.lg.com/us/home-audio/lg-SJ4R-wireless-surround-kit
Sorry, there was a problem. Please try again later.Hi Kamilah. The title description for the LG - 4.1-Channel Hi-Res Soundbar System with Wireless Subwoofer and Digital Amplifier, Model # SJ4R indicates that it has a digital amplifier and that amplifier is built into the Sound Bar. The difference between an amplifier and a receiver is that an amplifier alone just provides power and requires a separate pre-amp/processing unit to "control" it and provide connections for your components. you can use a preamp to control one or more separate amplifiers. there are also "integrated amplifiers" that have the preamp/processor built-in. either way requires a "tuner" in order to receive radio signals. (there are preamps with built-in tuners, too). A receiver consists of an amplifier section, a pre-amplification/processing section, AND usually a radio tuner (hence the name receiver), all in the same housing. So while an amplifier and a wireless receiver are not the same things as you stated, a receiver still has a built-in amplifier...^IFV
