Traditional Speaker Switches are often made of metal to dissipate heat from energy sucking impedance matching transformers and resistors. Some have weights such as metal plates inside of them to stop them from slipping on the surface when you press the mechanical buttons on the front.

Audioflow uses plastic casing as we do not need to dissipate heat, and also this helps us to have excellent Wi-Fi reception on our device. The reality is that Audioflow is typically operated without touch so we decided to not include weights to make it artificially heavier.

This is a decision made alongside our recyclable styrofoam-free packaging that is as kind to the environment as possible.

Audioflow 3S Switches do not include a volume control.  You would control volume from your source amplifier, typically using the app or volume buttons on your device.

Briefly, impedance is a measurement for how much resistance (or load) speakers place on an amplifier.

• The lower your impedance, the more power your amplifier would output. However, if the load is too low your amplifier may output too much power and be beyond it’s specification. It is important to stay above the minimum impedance rating of your amplifier.
• The higher your impedance, the less power your amplifier would output. This is generally not a problem but you may experience a slight reduction in audio quality due to the reduction in power output – this would depend on your specific speakers and amplifier but can often be imperceptible.

Note that impedance isn't really a static value, it moves around a lot as music is playing at different frequencies and volumes. Hence, this is always a nominal value.

Yes you can!  Using in-wall volume controls works well with Audioflow switches.

Some of these have impedance multiplying circuitry in them, try to aim for 8Ω per zone.

Yes you can, the app will show you all of the Audioflow Switches on your home network in a list.

Each Audioflow must be connected to it's own amplifier output and you can name each switch to match the name of the amplifier.

When all of the zones are turned off, the Audioflow Switch introduces a 200Ω dummy load to the amplifier. This is a safety feature which avoids your amplifier output suddenly becoming open circuit and allows it to dissipate it's energy.

Please note that this is a feature to be kind to your amplifier. We do not recommend using Audioflow to isolate your amplifier for long periods of time.

• The Audioflow Switch is a 2.4GHz device, it does not support 5GHz Wi-Fi
• 802.11b, 802.11g and 802.11n is supported
• WPA Personal and WPA2 Personal is supported

You cannot go through the setup procedure with a hidden SSID, however if you temporarily unhide your network to set up the switch you can then hide your SSID again once it is set up.
