The Thru output is for analog signals only and does not support Bluetooth. Therefore, a subwoofer connected to it won't receive Bluetooth audio. Keep this in mind when setting up your audio system if you use Bluetooth for streaming.
To play Bluetooth audio through your PA system, consider these solutions: Connect your PA to a mixer with built-in Bluetooth, like our Onyx series mixers. If you have a mixer already, use a generic Bluetooth receiver to stream audio wirelessly from your Bluetooth devices to your PA system, ensuring sound quality remains intact.
