X9 wifi fails to connect

invalid@example.com (mowntnbkr) — Thu, 10 Sep 2026 02:17:31 +0000

I just received the unit today. It recognizes my router, however once I enter the PW, the message “wifi failed to connect”. It is the same PW I have used for years, and I am not fat fingering it. Any help would be greatly appreciated. And yes, I have restarted the modem, router and unit.

x9 visual upgrade when ?

invalid@example.com (Liquid) — Wed, 09 Sep 2026 09:11:39 +0000

I noticed x9 has same internal led's as x8 so i assume there should/will be a visual upgrade as x8 recived.

For curious people go to
About -> My Device
and press six times name of your model

Model: Luxsin-X9 <- (thats what you should click)

internal LED's will light up, you can see them throu IR sensor and from sides of the unit, to turn LED's off, repeat above steps.

user wishes: USB Audio Output / External DAC mode

Dear Luxsin,

Would it be possible to add a USB Audio output mode to the X9, using the USB-A port as a UAC2 host, so that the X9 could send the DSP-processed main stereo signal to an external USB DAC while keeping the subwoofer outputs active?

Ideally:

main output: post-HPF / post-PEQ / post-volume PCM via USB
subwoofer output: existing analog Sub Out with LPF/delay
synchronized main/sub output

This would allow users to keep the X9’s bass management and DSP while...

Bluetooth issue…

invalid@example.com (Dave Christie) — Wed, 02 Sep 2026 15:12:02 +0000

Hi Everyone,
My Luxsin X9 is fantastic and working well, except… Bluetooth has stopped working. I had it set so that my Apple TV would connect if input set to Bluetooth. Now Bluetooth in “About” says “-“.
I have upgraded to firmware 2.0.0.9, factory reset etc. nothing. Not visible on any device to pair with.
Antenna is in firmly - taken off and reconnected. Wifi working perfectly.
Any ideas???
Cheers,
Dave
