The unBT2A is a 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 smartphone, laptop,

tablet or other Bluetooth® audio equipped smart device to the sound system.

The unBT2A features a simple pairing process that eliminates the frustrating experience

users often have with consumer grade Bluetooth® interfaces. Through the Axiom AXP2O

expander unit, which is included with the unBT2A kit, the product outputs balanced

mono or stereo analog audio on 3-pin depluggable connectors for easy connection to

commercial AV equipment, including the Q-SYS Ecosystem. The unBT2A USB port is

used for initial product setup at installation, and the Axiom AXP2O offers an RS-232 port

for third-party control.
