The LG S75Q Black soundbar has decent stereo frequency response straight out of the factory. It has a fairly balanced midrange that handles clean vocals and lead instruments. The S75Q soundbar has good center channel performance. Thanks to it, dialogue is reproduced clearly and accurately, and voices are localized to the exact place on the sound stage. The frequency response on this channel is fairly balanced in the midrange. The set of connectors is very similar to that of other inexpensive models. These are two HDMI ports (input and output), a USB port and an optical audio input (TosLink). You can connect the soundbar to your TV via HDMI or via optical connections. Since the device comes with an HDMI cable, this connection will be optimal.
Additionally, the LG S75Q has good support for audio formats via ARC, from Dolby Digital surround sound to lossless and object-oriented formats such as Dolby Atmos.
