Using the Alto Professional Bluetooth Stereo Adapter is easy. First, plug the adapter into the XLR inputs of your mixer or powered speaker setup. Then, pair your Bluetooth device with the adapter. You're all set to enjoy wireless audio. If you have a larger speaker setup, you can link two adapters together wirelessly for better sound. Note that this adapter can pair with another one or the Alto Professional Bluetooth Total 2, but not the original Bluetooth Total. Also, you'll need to get an additional XLR cable separately. To keep your adapter in good shape, recharge the battery regularly. It can run for over 6 hours on a single charge. Avoid exposing it to extreme temperatures or moisture, and store it in a dry place when not in use.
