In-Wall Speaker Installation Manual
Troubleshooting
No sound from all speakers:
Make sure the amplifier and source device (music streamer, CD player, Bluetooth receiver,
etc.) are turned on and music is playing. Check the connections between the source device and the amp to make sure
they are firmly connected and that the cables are in good condition. If all units are on and the connections are good, dis-
connect the AC cord from the amp, wait for 5 minutes, plug it back in and try again.
No sound from one speaker:
Check the cable connections on the speaker and the amplifier. If they are good, check the
connection from the source device to the amp, to make sure both stereo channels are connected. If all these connections
are good, twist the speaker to remove it from the bezel ring, then bring it down by the amp. If the speaker works, the
installed cable between the speaker and the amp is damaged and will have to be spliced or replaced. If the speaker still
doesn’t work with a direct cable to the amp (but other speakers connected to that amp do work), unplug the AC cable to
the amp, wait 5 minutes, then plug it back in and try the speaker again. If it still doesn’t work, contact Adept Audio.
Sound seems unfocused or bass is weak:
Check the polarity of the speaker cable connections on the amp and the
speaker. The marked (or white or red) conductor of the cable should be connected to the positive (usually red) terminals
on the speaker and the amp. The unmarked (or black) conductor should be connected to the negative (usually black)
terminals on the speaker and the amp. If the polarity of a connection is wrong, reverse it and listen again.
