unBT2A
Bluetooth® in-wall audio interface (Attero Tech by QSC)

The Attero Tech by QSC 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.
