The JIB/BT4R is a lightweight, compact, portable XLR Bluetooth® receiver for speakers allows a user to transmit high quality mono Bluetooth® audio wirelessly from a smart phone to an active speaker or mixing console. The receiver offers a practical, straightforward audio solution for venues that require a quick wireless set up. Just pair the receiver to a Bluetooth® enabled device such as a smart phone and plug it into an active speaker or mixing console. Using the JIB/BT4R eliminates cable clutter for a clean, hassle free set up. The rechargeable receiver enlists an internal 3.7V Lithium battery and comes standard with a micro USB charging cable that can be plugged into a computer or A/C adapter to charge. For a more permanent mixer installation, it can stay plugged in for a continuous power source. DJs accepting requested songs that they might not have in their track list can allow a user to Bluetooth® a song straight to their mixing console for live DJ mixing. Singers and musicians can stream audio wirelessly to the receiver while using another mic input for vocals. The JIB/BT4R can also be used for a number of other audio streaming applications including dance studios, aerobics classes, school and gym classes, house of worship, karaoke, weddings, and many more.
