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

Disconnect the SoundTouch

ampliﬁer. Disconnect AC power from the SA-4 ampliﬁer for three

minutes. Reconnect the SoundTouch

power to the SA-4 ampliﬁer.

Make sure the cables are in good condition and are ﬁrmly

connected at both ends for the speaker that 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.

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.

Check the speaker cable connections. Make sure the individual

wires are connected + to + and – to –.

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

objects, other audio/video components, and direct heat sources.

Replace the batteries in the SoundTouch™ controller.

If you are using a local volume control (VCA), turn it to the off

position.

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.

Disconnect the SoundTouch

ampliﬁer. Disconnect AC power from the SA-4 ampliﬁer for three

minutes. Reconnect the SoundTouch

power to the SA-4 amplier.
