I have no idea what i'm doing.....

Welcome to Chordie, Sisyphus!

What you've done there is a job to be proud of ... nice studio! I hope you didn't have to turn any cows or horses out to pasture in the process! Looking forward to hearing about your projects, your band, your music, etc.

Keep in touch, eh? (typical Canadian greeting)

Thank you , yes i've a LOT of questions....~S~

Sorry.  I thought you meant that you didn't know what to do about the dates. 

If you meant that you don't know what to do about live sound, that's a whole different ball of wax.  I used to do some very simple sound engineering.  There are some remarkably good white papers and beginner introduction write-ups available.  I'm sorry that I don't have any of those old links bookmarked or I'd share them.  I suspect if you do a Google Search on "Live Sound for Beginners" or "Introduction to Band Live Sound" or some such that you'd find some real zingers and maybe some Youtube tutorials.  If you've already got your live sound board, then you could search on it.  About the only thing I can tell you is to have the sound guy control the monitors, because otherwise the lead guitarist will cut everyone else out and crank himself/herself up to 11 and you'll have terrible feedback and it's all that anyone will hear.  Or the bass player, but since you're the bass player I"m sure you wouldn't do that.

It's been awhile but I used to run sound for a couple local bands and also took care of the lighting.You'll find every venue is different as to how you're going to set up your board. If everyone is playing through their own amp make sure your stage volume is loud enough that everybody can hear each other but not so loud it carries past your p.a. The bass (no knocks here) is usually the hardest to keep under control but you want that bass thump coming through your stacks so you can feel it. Get your board levels set so you can still turn up your leads but you're not clipping your meters. Remember to return any channels you turn up back to your original setting. I highly suggest you find somebody to run sound for you as trying to do it from stage can be challenging. Running from the stage you don't have the option of tweaking things while you're playing and if something needs adjusted you're having somebody drop out to do it. The lighting isn't such a big deal. If you're using par cans make sure everybody's covered and watch using green. It's fine to point a green light at somebody if you're doing back lighting. Pointing green at somebody from the front isn't wrong but it tends to make for a sickly looking performer. Set your sequencer and run a couple quick checks. If back lighting your light should extend slightly past the band but not blinding people dancing/watching. You may have a few bumps in the road figuring everything out but if you set up for practice like a regular gig (p.a. and lights) you'll figure it out. I prefer to run everything through the board and use monitors so everyone's on the same page and level but that's me. Good looking job on the studio and hoping things work out for you. As long as people can hear everything and nobody gets out of control,it's all good. Good luck

Get yourself a copy of Room EQ Wizard, measure the heck out of that place, and treat it accordingly.

Then come over to my house and build another one.

Jerome, i do than you for the  room wiz link, in fact it appears i may quite well spend a lotta time there........and we got all powered stuff, 2 powered mains, 4 powered monitors, board takes 4 mics and has all the effects, could fit on a barstool.....i also have a wireless ear monitor, but haven't quite figured it out yet......so here's the deal, we're 'stage volume' with only volcals going thru the 'PA'  , trying to run as light as possible, no  heavy woofers , i literally bought it all with weight in mind , just haven't run it all 'live' yet so i'm on pins/needles  ~S~

Interesting Phill,    so how would you place the mains?  Would they be in front, or in back of the band?  ~S~

Mains are always in front of the band.  The last thing you want is your mains behind your microphones.

No worries.   Generally speaking, if you have a speaker cone pointed at the business end of a microphone feeding that speaker, you're probably doing something wrong.  The good news is that the setup will let you know immediately by making a horrible screeching noise.
