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.

No, Audioflow does not accept banana plug connections. The 5.08mm Pluggable Terminal Blocks which come with Audioflow are designed for raw speaker cable.

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.

If you are using a system such as Bluesound or Sonos with rear surround speakers paired to your amplifier, we typically would not recommend you connect your speakers via Audioflow. You may continue to have surround audio while the speakers are on in a different room.

If you are using an AV Receiver with rear speakers, we would typically not really recommend using Audioflow on your main / front speakers for the same reason as above. If you are using a stereo Zone B / Zone 2 output it may be possible to use Audioflow if your amplifier supports 4Ω speakers on these connections.

We do not recommend Audioflow if you have a Subwoofer connected to your Amplifier either wired (eg with an RCA Cable, or Speaker Cable) or wireless (eg Sonos, REL Arrow or equivalent).

If you have a crossover or high pass filter on your main speakers this will affect other areas you may want to connect via Audioflow. If your speaker output is full range, you may have a situation where you have speakers on in one area and the subwoofer on in another area. Also, Audioflow does not support connecting speaker level connections to a subwoofer.

In most cases, it's just not going to work out. Please get in touch with us if you would like any further advice on whether Audioflow is suitable for your system.

The Audioflow App does not see your physical location and we do not collect any such information from our users.

However, the Audioflow App does need to know whether you are connected to your home Wi-Fi Network so that it can control your Audioflow. To know such information about your Wi-Fi connection which is also important for the setup process, the app does need 'Location' permission.

Audioflow checks for a new firmware update when it starts up and these are installed automatically if they are available.

You can manually initiate this process simply by rebooting (power cycling) your Audioflow.

Learn more about firmware versions.

• 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.
