Description

The Audioflow 2 Way Smart Speaker Switch lets you connect and control two pairs of passive speakers from a single stereo amplifier.

It is ideal for creating two listening zones, such as a kitchen and dining room, bedroom and en-suite, or living room and garden, without requiring a separate amplifier for each area.

Either speaker zone can be used independently, or both zones can play together.

Control is available from the touch-sensitive buttons on the front, through the Audioflow app over Wi-Fi, using compatible Amazon Alexa voice commands or through contact closure connections.

One Amplifier, Two Speaker Zones

Connect the speaker output from your amplifier to the Audioflow, then connect one pair of passive speakers to each zone.

Both zones receive the same audio source and share the amplifier’s volume level, while the Audioflow allows you to choose which areas are playing.

This makes it a practical solution for ceiling speakers, wall-mounted speakers, bookshelf speakers and passive outdoor speakers installed across two adjoining rooms or areas.

  • Control Two Speaker Zones: Connect two pairs of passive speakers to a single stereo amplifier and switch either zone on or off independently.
  • Simultaneous Playback: Listen through either speaker zone individually or play both zones at the same time.
  • Audioflow App Control: Select your speaker zones remotely using the Audioflow app for compatible iOS and Android devices.
  • Amazon Alexa Compatibility: Use compatible Alexa voice commands to switch your speaker zones.
  • Front Touch Controls: Operate each zone directly from the touch-sensitive controls on the front of the unit.
  • Contact Closure Control: Integrate the switch with compatible third-party control systems using its contact closure connections.
  • Amplifier Protection: Series switching helps maintain a safe speaker load when both zones are active, while a 200Ω dummy load protects compatible amplifiers when every zone is switched off.
  • Made in the UK: Designed, manufactured and production-tested in the United Kingdom.

Important Compatibility Information

The Audioflow is a speaker selector, not an amplifier. It must be connected to the speaker output of a suitable stereo amplifier and can only be used with passive speakers. It does not power speakers by itself and is not intended for active or powered speakers.

Both zones play the same audio and use the same amplifier volume setting. The Audioflow switches each zone on or off but does not provide separate sources or independent volume control for each area.

When both zones are active, the connected speakers are wired in series. For example, a pair of 6Ω speakers on Zone A and a pair of 8Ω speakers on Zone B will present a 14Ω load to the amplifier. This protects the amplifier from an excessively low impedance, although the available output may be shared between the two zones.

The smart-control features require a 2.4GHz Wi-Fi network. Please check your amplifier, speaker impedance and proposed wiring before ordering. If you are unsure whether the Audioflow is suitable for your system, contact our team and we will be happy to confirm compatibility.
