Frequently Asked Questions for the On-Q/Legrand airQast™ Wi-Fi Network Music System, covering setup, streaming, and troubleshooting.
The airQast Wi-Fi Network Music System is operated by a controller — an app downloaded to your Android or iOS smartphone/tablet. With the controller you can select music sources, create collaborative playlists, and control speaker volume.
The airQast Controller App supports a wide range of operating systems, including Apple devices running iOS 4 or newer (iPod Touch, iPhone 3Gs/4/4s/5, iPad) and Android devices running Android 2.2 or newer. Proprietary Android systems such as Kindle Fire, Kindle Fire HD, Nook Tablet, and Nook HD are not supported.
The server is the airQast software program installed on a PC or Mac. It bridges the airQast speakers and the controller app, providing access to Internet Radio and music files stored on your PC, Mac, or network-attached storage drives.
The mobile controller can control airQast speakers without the server running. However, some sources — such as Internet radio and files stored on your home network — require the server to be active.
Direct streaming transmits music services (such as Pandora) and files stored on your smartphone or tablet directly to the airQast speakers via Wi-Fi, without going through the server.
No. Music with Digital Rights Management (DRM) protection is paired with its associated player and cannot be played by airQast. Non-DRM iTunes files can be played as long as your iTunes folder is mapped to the airQast server during setup.
Yes — airQast requires that your wireless router or access point support multicast. If multicast is disabled, enable it. Most modern routers support multicast by default.
airQast connects to 802.11G or 802.11N networks. It cannot connect to an unprotected/open network — the network must be secured with a password.
Make sure the supplied speaker wire is securely attached to the connectors on both speakers.
Check the speaker wire polarity — the red wire should connect to the red terminal and black to black on both speakers. Crossed wires put the speakers out of phase and cause distortion.
