I recently purchased an iphone X and it can't find the HK SB20 using Bluetooth. I have powered off/on the phone and speaker. I verified that the Bluetooth symbol is flashing on the speaker and Bluetooth is turned on on the phone. It worked with iphone 5.

I am going to move to Europe. Does the system support 220 v? Thanks

Asked by: Axel V
Depending on where you purchased the HKSB20 it will be rated 110v or 220v. In this case, you will need a step down converter to 110v.

Does the sb20 have an auto switch off function? ie when the TV is switched off it shuts down, If not can it be connected to a power down plug so that when I switch off the TV it kills power to the the sound bar?

Asked by: Zorro
Hi The HK SB20 accepts HDMI CEC power commands. So, when your TV is set up to send a CEC Power On/Off command through HDMI, it should power on and off the SB20 together with your TV. In any other case, when the SB20 does not receive an active signal for 15 minutes, it will go into Standby, and after 30 minutes it will shut down completely

is it possible that there's not a broad spectrum of bass adjustment on the subwoofer?

Asked by: Stephy
The remote control has a BASS +/- control, which controls the level of bass output on the subwoofer.
