ProblemWhat to do
Neither speaker 
plays •	
Make sure the amplifier is connected to AC (mains) power.
•	 Make sure the plug is inserted fully and the AC (mains) power 
outlet is powered.
•	 Make sure content is selected via the SoundTouch
™ app.
•	 Disconnect the SoundTouch™ wireless adapter cable from the 
amplifier. Disconnect AC power from the SA-4 amplifier for three 
minutes. Reconnect the SoundTouch
™ wireless adapter. Reconnect 
power to the SA-4 amplifier.
Only one speaker 
plays Make sure the cables are in good condition and are firmly  
connected at both ends for the speaker that does not play.
One speaker still 
does not play Try connecting the speaker that does not play to the other speaker 
cable. If the speaker still does not play, the problem may be with 
the speaker. If the speaker now plays, you know the speaker and 
the cable are both good. Disconnect the cable from the ampli-
fier terminal, and connect it to the other terminal connector. If the 
speaker now plays, the problem is likely in the other speaker cable. 
Replace it. If the speaker does not play, the problem may be in that 
channel of the amplifier.
Right and left 
stereo channels are 
heard on the wrong 
speakers •	
Make sure the cable connected to the SPEAKER OUTPUTS L  
at the amplifier are connected to the speaker on the left in your  
listening area, and the cable connected to the SPEAKER  
OUTPUTS R at the amplifier are connected to the speaker  
on the right in your listening area.
Bass or treble is 
weak Check the speaker cable connections. Make sure the individual 
wires are connected + to + and – to –. 
Interference •	Make sure the speaker cables are firmly inserted in the terminals 
on the back of the speakers and on the amplifier rear panel. Check 
to be sure no individual wires are touching across terminals. 
•	 Make sure the SoundTouch
™ wireless adapter is away from metal 
objects, other audio/video components, and direct heat sources. 
SoundTouch
™ 
controller does not 
adjust the volume •	
Replace the batteries in the SoundTouch™ controller.
•	 If you are using a local volume control (VCA), turn it to the off  
position.
Volume suddenly 
decreases •	
Lower the volume setting to see if the level returns to normal. If so, 
the sudden loss of volume was an intentional action of the ampli -
fier’s overload protection feature. This engages automatically if the 
volume is set too high and is overdriving the speakers. Choosing a 
lower setting should ensure continuous, even volume.
•	 Disconnect the amplifier from AC (mains) power and allow it to 
cool. Increase ventilation. Reconnect to power. If the volume level 
returns to normal, the sudden loss of volume was an intentional 
action of the amplifier's thermal overload protective feature. This 
engages automaticaly if the amplifier overheats. Increasing ventila-
tion should ensure continuous, even volume.
Wireless adapter 
does not awaken 
from power saving 
mode.  Disconnect the SoundTouch
™ wireless adapter cable from the 
amplifier. Disconnect AC power from the SA-4 amplifier for three 
minutes. Reconnect the SoundTouch
™ wireless adapter. Reconnect 
power to the SA-4 amplier.
