Building an audio room - 12x22 - electrical plan?


I am at the pount of adding a new room which will be my audio room. It will be 12x22 feet with the audio on the short wall. While I would like to Go wider than this I do have size limits that I have to adhere to. The contractors will be adding electric to the room and I have not yet decided what to request. Based off of what I have read I am assuming that 2 20 amp circuits are the way to go. Any other recommendations? I am looking to add things now that will be easier done during construction then down the road.

I will also be adding a layer of Homasote sound barrier to the sheetrock to keep me toe tapping to myself. The floor will be carpet. Any other items to consider up front?

+1 for # of outlets. Will your room have any HEat/AC power requirements? If so keep on separate circuit, Same true for lighting and other non audio outlets. Keep the latter two need on opposite phase from the audio circuits.
Thanks for the responses. I am leaning towards 3 dedicated circuits right now - one per mono block and one for the pre. The fourth circuit will be for the lighting, computer etc.

I am wondering about adding 240v to run european equipment. Is this a good idea?
Michael:
The advice above is good. They are talking about (4) duplex receptacles, with each duplex on its own dedicated circuit. Amps on 20A with #10 is good advice and only a modest upcharge from USA code minimum of #12. Lighting is a separate (5th) ckt. Yes, your electrician will think you are wacky. Good luck.
I did run 2 ea 220 Volt lines into my room (1 on the amp wall and one on the front end wall) in addition to the 6 ea 120V lines so that I can run 220V equipment when needed. I was however made aware of, here on this forum, that it is not up to code to do so in a residential setting so your electrician may not want to do it for you.

Best of luck

It's not code to run 220 power in a residential setting? I'm curious where you got your information. Electric dryers, water heaters, and ranges all run on 220 power. There is no code that says you can't have 220 power in your house. Or even three phase for that matter.

I don't know any stereo gear that runs on 220v, however.
