Q: QuestionWhat is the distance range of the WISA connectivity to the Klipsch speakers? Could I put more RW-51M speakers in other rooms (for music)? Can they all be independently controlled, turned on/off and volume changed?
Asked by kolart.
- A:Answer WiSA has a 30-foot range and supports 24-bit resolution with sampling rates of 44.1-, 48- and 96kHz without any compression or conversion. It can handle other sample rates by up- or down-sampling the material if the playback device doesn’t handle that natively. It is a closed Wi-Fi network, pairing devices devices should be no hassle at all. For the most part, it’s said to be auto-magical, with everything just connecting out of the box as you turn it on. The only time you might conceivably run into issues is when you change audio sources. At that point, a simple reset button should have you up and running with your new source in no time. It steers clear of with your Wi-Fi router and privately uses less-populated 5GHz frequency bands (with 24 RF channels available in the 5.1- to 5.8GHz spectrum) along with various techniques such as spread spectrum, error correction, and dynamic frequency hopping to avoid interference and maintain signal strength. Though WiSA shares many attributes with wireless multiroom speakers, it is not a multiroom, whole-home music system. The LG NanoCell 90 Series 2020 55 inch Class 4K Smart UHD NanoCell TV w/ AI ThinQ® (54.6'' Diag), Model # 55NANO90UNA has the required software to let you control a WiSA set of speakers and when connected to the speakers via the WiSA transmitter, it will only support 2.0 or 5.1 configurations...^IFV
