Gobos - Can you please check this out?
« on: January 12, 2010, 02:53:24 pm »

Hi there!

I've re-read my post, and it seems a bit long.. I hope you can understand my question and be of some assistance.

I work in a small recording studio, but we have a decent sized tracking space. Lately we've been trying more and more to get into tracking bands live, playing together in the room. It's a great approach to recording, but now more than ever we need to get some nice gobos to control the bleed and to allow us to place the musicians where they feel good - regardless (well, kind of) of the sound of that particular spot in the room.

We asked an acoustician that works in a pro audio company not far away from us (and that builds gobos and stuff) to give us an estimate, but the ballpark he's aiming at seems a bit over our budget.

In the meantime, I decided to ask for an estimate in another company (not really an audio company, mostly they manufacture and assemble exhibition stands/booths and stuff like that). In order to do this we asked a designer to make us some drawings of what we thought that could be a good screen.

We saw the BBC gobos PDF file in the Mercenary Audio website and after some more google image search we came up with something like this:

- Number #1 -

This gobo would be 2mx1x0.15m (something like 6'7'' x 3'3'' x 6'' - I hope I got this right, we use the metric system).

One side would be a rigid surface, like plywood, and the other would be some kind of thick fabric (I don't know the english word for that). On the inside it would be stuffed with rockwool or some kind of absorving foam.
The window would be made from 5mm thick plexiglass.

- Number #2 -

This gobo is exactly like the first one, but with no window.

- Number #3 -

This is square gobo - 1m x 1m x 0.15.
The filling is the same, but this one has no legs so we can stack them.

The legs would be made in a way that would allow us to put the gobos together like this:

We have the actual drawings with all the measures, these are just images so you could see what I am talking about.

Do you think this could work?

Probably it would be better if one side of the gobo was a diffuser (but that would be more expensive). We thought that if we get a reflective side (insted of 2 absorbing surfaces) we can have more options in the room.

My main concern is the plexiglass screen. Will it cause some nasty reflections even? We don't plan to put the mics too close to the window.. Would the plywood surface have the same problem?



Our room is aprox. 12ft. high.

Sorry for the long post, I hope to get some feedback here before I can send them the drawings!

Thanks,

Joao.

Hi,

I don't know about the price, these are only sketches.

I'm waiting on some estimates, i'll let you know as soon as i get them.

Gobos are pretty straight forward really. You need to assess your particular needs, but usually Gobos with both surfaces absorptive are the way to go in smaller rooms. It's good to have a couple with windows, but in my experience they end up not being so very useful so don't stock too many of those.

Just get the 2/1m fully absorptive ones.

And make sure they are built to last! Tough!  

I hate those cheap unstable Gobos with noisy loosen feet.  Confused

Hi Thomas,

Thanks for chiming in!

I understand that the ones with windows would be less effective than the fully absorptive gobos. Probably I'll just order 2 or 3 with the glass, in order to the musicians to feel less confined.

Hey Joao,

Just a comment but I read Thomas's post to infer that you should consider making both sides of the gobo absorptive instead of one side absorptive and the other to be plywood...

And more gobo's without windows than with windows..

I built some with a reflective side and an absorptive side and would use the rockwool on both sides next time... Just because I don't want the reflection on one instrument/mic and no-reflectionon the other instrument/mic... At least that's what I have found to be practical in my situation...

Best,
j

These exhibition stands seems to be very simple style. What does there price range from.
Good pictures.
Anymore styles of Display stands and Exhibition stands?

Let me suggest that you watch the following video (with good headphones or speakers).  

http://www.realtraps.com/video_diffusors.htm

It really changed my mind about the hard side of the gobo.  I think we're going to go with absorptive on one side and diffusors on the other.

Good luck with your project.  Please post photos or updates when you move forward.

Most gobos I see or build these days are designed to be used as "movable booth". They can be assembled like a box if you will. This is how they are used most of the time.

It avoids having to build too many small booth that seldom sound really 'right' anyway. I've seen so many end up being used to store mic stands, Patch cables and amps...

Not sure a diffused side would have a lot of use. And it would likely make the Gobo very heavy to move around (and it's already pretty heavy).
A separate set of Skyline diffusors can indeed be of use in some specific but rare situations.

There's nothing like a well planned live room really Smile

I have seen Gobos with diffusers particularly to record small ensembles in large tracking rooms.

You can make a ligther Gobo using EPS for your diffusers.Not exactly as wood but cheaper
