Brand: Sound Town
 The Sound Town SWM15-PROS is a compact karaoke microphone mixer system. It comes with dual-channel, 8 selectable UHF frequencies per channel (16 channels in total) and is interference free. The HDMI, 3.5mm (1/8”) input and output connectors makes it easy to connect with various devices including TV box, smart TV, home theater systems, receivers, speakers, amplifiers, notebooks and tablets, and more.   With a built-in HDMI ARC (Audio Return Channel) connector on the SWM15 mixer, it allows you to connect to almost any smart TV through an HDMI cable. Simply plug the HDMI cable to the HDMI ARC port on your Smart TV and plug the other end of the HDMI cable to the HDMI OUT (ARC) port on the SWM15 mixer. The smart TV is required to have an HDMI ARC port and the HDMI cable is not included.   The SWM15-PROS now provides an optical solution. The SWM15-PROS’s Audio Out port can be served as both an AUX (3.5mm Jack) or an optical port. This makes it convenient and versatile to fit almost any connection method, specifically when your speaker or soundbar does not come with an AUX input connector and better yet, if you want to stay digital. With the included AUX to AUX or Mini Toslink to Toslink cable, simply connect the karaoke mixer’s Audio Out/Optical Out port to your speaker’s AUX or optical input port and you are all set.  The microphone mixer enables you to mix mic signal with music without using an additional mixer. It comes with two wireless microphones and can support two wired dynamic microphones (not included). The rotatory control knobs can swiftly adjust the volume of your music, microphone, echo and tone to the desired level. It is ideal for karaoke, DJ music and house parties.  Important!  If you intend to use a smart TV as the input source, you will need external speakers (not included in the package) to connect the TV to the SWM15 receiver and output the sound through the speakers.
