The WILLIAMS IR SY22 D IR + System uses invisible infrared (IR) light to broadcast speech or music to wireless infrared receivers. Listeners can also use their own personal electronic devices with Wi-Fi. The new IR + is designed to support those who want to use their own smartphones and headphones for a more discreet assistive listening experience. Simplicity is also available for those who want a more traditional assistive listening system with a dedicated IR receiver and headset. Venues no longer need to choose between providing IR or Wi-Fi assistive listening systems. IR + supports the iOS and Android WaveCAST Receiver Apps and the Wi-Fi Receiver-- in addition to all of the current and legacy Williams AV IR receivers. The system is designed to transmit high quality audio for hearing assistance and language translation applications. Because the system uses infrared light for transmission, it is not affected by interference from radio equipment and does not interfere with radio equipment. No FCC license or radio approval is required. The system can be used with microphones as a stand-alone system, or can be connected to other sound equipment. Infrared-systems generally cannot be used in direct sunlight because of sunlight's large amount of interfering infrared light
The IR + is intended to be set up on an already existing Wi-Fi network; however, upgrades to your network equipment may be necessary depending on the performance desired from the IR +. For instance, a higher-end, more powerful router will allow more users to connect to your audio stream than using a cheaper, less powerful router. The Wi-Fi network will need to be accessible to the users who will be listening to the audio. A public or Guest Wi-Fi network will usually be ideal for ease of accessibility. If the user's devices cannot connect to the network due to security settings, they will not be able to hear the audio. The IR + system will put a demand on the network. If the network cannot handle the demand, whether because it is being used for other networking needs or because the networking hardware is not strong enough, the IR + will be unable to reach its maximum audience. When streaming to a small or medium sized audience, a basic networking configuration may suffice. When streaming music using multiple channels (such as having several IR + units on your network), a powerful router and network configuration is more likely to be required.
Network Cable Connection:
The Ethernet port can be used to connect the IR M1 to a local network. A network connection is required to access the IR M1 webpage. The webpage is needed to configure some device settings after the system is set up.An Ethernet connection alone will not allow the Wi-Fi broadcast features to work; a Wi-Fi connection must be available on the network. A network connection is not required for broadcasting over infrared. Once a connection has been established, an IP address will automatically be assigned to the IR M1. Device settings can then be set via the website, including changing any network settings.
