Troubleshooting/QA
1: Can I use T10 to create a 2.1 Channel system?
• Yes, you can connect two passive speakers via "Speakers Out"
and one active subwoofer via "PRE-OUT" to create a 2.1 Channel
system.
• Please use a 3.5mm audio cable to connect your active
Subwoofer to the "PRE-OUT" output port.
2: If I have multiple speakers distributed in different
rooms, can I control them all at the same time?
• Yes, you can control the sound level and left and right channels
of each speaker on your phone via the WiiM APP. You can also
choose synchronized playback or individual playback in the WiiM
APP to achieve the effect you want.

3: Why does the sound is cracking or make a lot of
electric noise?
• Please make sure all the cables completely pushed into the
devices, incompletely connection will cause this cracking.
• Please remove all the inputs then check whether cracking noise
disappear or not, the cracking maybe from the audio source or
input cables.
• If you are not using the original factory standard power supply,
please replace the power supply before testing. Many power
supply in the market have large interference coefficient, which
will cause a lot of current sound.
4.How to play my music?
• T10's Wi-Fi setup as well as multi-room and stereo configurations
are done via the WiiM app. After setup you can play your music
using the music players and streamers we include or leave the
app and use your own.
• For example, if you’re into play on your iPhone, select T10 as the
phone’s audio output in the iOS Music app. Or if your favorite
player has audio output settings included, as many do, you can
select T10 as the output within the app. So you’re not stuck using
only our app as there are other options for Android and iOS.
Note: Since there is no Airplay for Android, you can only
drop music to T10 in the music apps that support it. Due
to the compatibility problem, not all music apps can play
music smoothly at the beginning, which requires you to
be patient and try a few more times.
