Troubleshooting
If you have no audio output, please check to ensure you do not have another Zone activated which does
not have any speakers connected to it. It is possible to disable a Zone via the Audioflow app to avoid
activating spare zones on your switch which do not have speakers connected.

Check your Speaker Impedance & Amplifier Minimum Impedance
It is important that your speaker system does not fall below the minimum impedance rating accepted by
your amplifier.
• 3S-2Z is a series switch; the lowest impedance set of speakers connected to the switch is the minimum.
• For the 3S-3Z or 3S-4Z switches; if all of your speakers are 8Ω rated, the minimum impedance is 4Ω.
• For more information on speaker impedances, please visit our website.
