I know live music is much different then DJing, but have been asked to provide audio equipment and support for a friend that is filming a music video and wants to create a live show as part of the video. Never done a live event. Should I consider it just to learn? And what would I need to know? Thinking 2 18" subs with 12" tops for main, 2 12" monitors for the stage, I have 8 Shure SM57 mics, so those I would think should work. I told him if he needs wireless mics, he is renting those. Direct boxs for the instrument input, I would assume. I have a 12 channel and an 8 channel mixer. Is there any issue with feeding the 8 channel into the 12 if more channels were needed? Also thinking I would probably need to rent a snake if using the traditional FOH setup. Sounds interesting just to learn in a no stress environment and make a few bucks while helping a friend.
