We recommend connecting a maximum of 16 Phorus or Play-Fi products to your home network. You can certainly add more, but we can’t promise the performance will be as solid as it is with this limit.
You can connect to up to eight Phorus or Play-Fi products and stream the same song to all of them at once from your phone, tablet, or Windows PC.
You can stream audio to up to four zones at once, from a single device. Each zone can have up to eight speakers grouped together, with each zone streaming from a different audio source from within the Phorus app.
Up to eight different people can be streaming different songs to different speakers from different devices at the same time, without any interference or congestion.
