[Black Tuyú] Introduction

Hello everyone. My name is Ignacio Guerrero. I'm new to the forum, but I've been reading/learning from it for quite a while now. My partner and I are designing/building a small (maybe not so small) studio in General Madariaga, Buenos Aires, Argentina. We have already built the outer structure. I have too many questions, but I'll try to post them one by one. But, first of all, I would like some feedback about the overall design. Do you think it's OK? Did I miss somthing? Probably a lot. Q1: As you can see, I've numbered the walls in the Control Room (CR1 to CR7). There are two sets of parallel wall (CR2-CR5 and CR3-CR6). Would that be a problem? Should I tilt CR2 and CR6 by 5º-10º ? Q2: I'm planning the lighting/wiring of the studio right now, and I'm wild guessing a lot here. How many connections would I be needing in each room? I'm talking mics, lines, MIDI, headphones... What is avarage? We are buying a YAMAHA 01V96V2 (12 MIC/Line CH + 4 line CH + 8 Aux CH) and already have a Hoontech DSP2000 (8 CH unbalanced A/D converter) but we will eventually grow. Thank you for your patience and, please, don't hesitate to ask for more details.

you could try turning the CR to face the vox booth. also, the number of connections per booth will depend on your styles of recording. generally, the drum booth should be equiped to handle close micing of the drums so maybe 12-16 low-z connections. each vox booth, 4-6 lo-z should be plenty, and live room, another 12-16 lo-z connections. plus returns in each - about 4 headphone returns per booth, and 8 returns in the live room. in the live room, drum booth i'd have 4 midi each. and 4 line inputs per booth plus 12 lines in the live room. so maybe 32-40 lo-z, 20 headphone, 24 line, and 8 midi is probably enough for most scenarios with a mixture of live and eletronic instruments. much depends on your budget. if nothing else, leave some space in the inter-room conduit to pull additional lines. I'd have separate conduit for lo-z, line, and midi. also consider some tv (cable), telephone/network lines - again separate conduit for those.

Thank you, Gullfo for your answers. I like what you propose. The design of the CR is great. In fact, one of my first drafts faced the Vocal Booth. I designed the CR facing the Live Room and the Drum Booth so I could have direct eye contact with as many people as possible. In most cases, I record vocals on a second stage, more intimate and with less people. I found amateur vocalists to be somewhat shy. That's why I let the VB connect only to the CR and not to the LR (except for the window). Something like having a Studio A and a Studio B, with a shared CR. Anyway, your CR looks bigger and with a better symmetry, so I'll definitely think about it. About the wiring, I'll do as you say. And you're right about the TV and network lines. Thanks for the advice. I have a lot of questions about wiring, but I'll leave those to the Installation and Wiring forum. Now, I have some more questions about the Drum Booth. Please, if you think this should be in a different post, just let me know. Every wall in the Studio should be like the image I'm posting. A layer of 12 mm Gypsum Plasterboard, 70 mm steel studs stuffed with glass wool, a 50 mm air gap and another single layer dry wall like the one I just described. Should that be enough to prevent bleeding from the Drum Booth to the Live Room? Would it be better if I leave, for instance, a 10 cm air gap instead? What is, acoustically speaking, the differnce between rock wool and glass wool? Too many questions, uhh? Finally. Gullfo, I see you changed the angled pair of aluminum sliding doors in the drum booth for glass double doors (or is it only my interpretation?) Truth is, I'm very concerned about the Drum Booth. I wouldn't want any noise leaking from it. Speaking of doors, what is the better solution? We have a $10000 budget, but we're prepared to expend as much as necessary in the long term. Thank you all for your cooperation.

the wall design looks good. if you can afford 10cm gap then it should help. you could also consider flipping the walls and making them "inside-out" to get some treatment benefit and the isolation. check John's SAE site for details on walls. the doors are sliders but could be double doors - either way you want solid exterior grade double glazed with tight seals as a minimum. the double doors might be nice in case you want to open the booth and/or have large drums to load in/out. i also pictured a raised platform in the drum booth. if you can use concrete to create the drum riser floor, it will keep the resonance frequency lower and keep the bass drum tight. use mineral wool or 703 insulation under the riser floor to "float" it (or buy proper isolation jacks). keep in mind the ceiling can be a major place of sound transmission so ensure the ceiling has enough mass to isolate. add more over the drum booth but leave the drum booth ceiling higher to add absorption and some diffusing bits.
