The unBT2A is single gang Decora style in-wall Bluetooth® audio interface aimed at adding Bluetooth® audio connectivity to installed audio systems. The unBT2A can be used in any venue where there’s a need to stream Bluetooth® audio from a smart phone, laptop, tablet or other Bluetooth® audio equipped smart device to the sound system. The unBT2A features a simple and consistent pairing process to eliminate the frustrating experience users often have with consumer grade Bluetooth® interfaces. Through the Axiom AXP2O expander unit (shipped with the unBT2A), the unBT2A outputs balanced mono or stereo analog audio on 3-pin depluggable connectors for easy connection to commercial audio equipment. The unBT2A USB port is used for initial product setup at installation and the Axiom AXP2O has an RS-232 port for 3rd party control.
