A:AnswerHi Bao, thank you for your question. The battery is separate but you will find that they may sell them together in a pack dependant on where you purchase from.
A:AnswerYes. I tuned the volume starting from off up until you start to hear static and then back down. I set mine to level 3/10 and use a pre amp and they are Chrystal clear and can be very loud w/o distortion easily filling a large room with 100 plus people in it. .
A:Answerthe S1 Pro doesn't directly connect to the internet. It will connect to bluetooth on your smartphone or computer and as such could be used to stream music from the internet.

A:AnswerThe alarm is in your Bluetooth device - phone, tablet, iPod. Or connected with the 1/8 inch audio cable. This speaker does not have a built in alarm.
A:AnswerFirst you have to connect 2 speakers together ( Go to Bose connect and follow steps to connect them ) Unless your mixer has bluetooth , you can connect them via bluetooth.
otherwise use cable to connect from mixer to speaker.

A:AnswerHello NTD,
Thank you for the question. If you already have the Karaoke app set up with your iPad, you can stream the audio portion to the stereo paired Micro and S1 Pro speaker. The stereo pairing can be done using the Bose Connect app and one of the speakers must be paired with your iPad.
Hope that helps.
