inside a bass reflex cabinet with a rear-firing port. Because its wireless, can place
the subwoofer almost
anywhere in your room (up to 33' from the soundbar). But, it is better to place the subwoofer near the

reflections. The wireless powered subwoofer does require an AC outlet

system is equipped with a HDMI 2.0 input and HDMI 2.0 ARC output that support up

Digital/DTS multichannel audio formats (including Dolby Atmos). The ARC (Audio
Return Channel) function of the soundbar HDMI output enables an HDMI capable TV
to send its audio stream to the HDMI output of the soundbar system.
Notes: Because some televisions, the ARC-enabled HDMI input
will only pass 2ch PCM from devices connected to the TV via HDMI or analog,
we recommend that you connect your Blu-ray/DVD player or Satellite/Cable box
to the LG SK8Y directly; and then connect the SK9Y's ARC-enabled HDMI output
to your TV's ARC-enabled HDMI input. This setup will give you with the best
overall sound performance.

analog audio input and one optical (toslink) digital audio input. The optical
digital input supports Dolby Digital (up to 5.1ch), DTS (up to 5.1ch), and PCM
(up to 2ch) audio signals.
Note: The digital optical output terminals of some
flat-panel TVs only send an audio signal in 5.1ch when receiving Dolby
Digital/DTS surround sound from the TV's built-in tuner, network connection,
or connected USB device; and will output only 2ch stereo from sources
connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or
