Title: Mic height config question
Post by: 69mako on April 18, 2008, 12:06:18 AM

I just got a set of Busman mics.  I've been playing around with different lics configurations.  I notice that I am unable to set up the mic in DIN because the rear of each mic hits each other.  My question is:

How critical is the mic height in relation to each other when running the different mic configurations?

Thanks,
Mako

Just make some spacers DIY or buy these:

Thanks for the reply.  Spacer was my plan but I wanted to make sure there were not adverse effects from it.

Thanks

The height, when minimal, is no consequence.  DPA has a spacer for their "standard" (SDC) cards to raise one over the other by the diameter of one plus a small amount when used on their mic bar.   8)

Try to imagine sound waves from a far field your horizontal placement is critical the vertical placement only matters as far as alignment goes unless you're talking about many many feet.  It just becomes more difficult to get the arrival queues correct on near coincident techniques with greater spacing.  Coincident techniques are a bit easier because you can still draw that visual alignment.

Look at the configuration pics to help you see why it's not a problem.
