Using the Alto Professional Total 2 Bluetooth Audio Adapter is a breeze. First, find the XLR input on your mixer or powered speaker and plug the adapter into it. Then, turn on the Bluetooth function on your device, like your phone or tablet, and search for available Bluetooth devices. Select the Total 2 adapter from the list to pair them. Once paired, you can play audio wirelessly. If you want a cable - free stereo setup, you can link two Total 2 adapters together. Just make sure both are in pairing mode and connect them. When it comes to the battery, use the included USB micro cable to recharge it. Try to recharge it when the battery is low to keep it in good condition. Remember, this adapter can pair with another Total 2 or the Alto Professional Bluetooth Ultimate, but not the original Bluetooth Total. So, don't try to pair it with the original one, or it won't work.
