Topic: Vertical angle for mic configs..

[phishn]

What vertical angle do you use when setting up mics and does it vary with different configs?  I generally point mine down about 5 degs all the time.

[Sean Gallemore]

depends where the stacks are relative to the placement of your mics

[jpschust]

yah, though ive noticed a LOT of people failing to point their mics a touch upwards when the stacks are well above where they are.  It's like they will run their stand with LD's on them way high (often to the point of instability) but a lot of the same effect can be achieved just by tilting the diaphragms up about 5-10 degrees

why?

pointing up a touch can help but why down?

[phishn]

i like bass..and logic says the subwoofers are usually at the bottom of the stacks.

[Tim]

yes, so I usually keep my stand low for the same effect. angling the mics down is going to give you reflections off of bodies, heads and the floor...

The bass that the subs put out is primarily omnidirectional (to a point). However, the midrange is not. Pointing down to get more bass doesn't make a lot of sense by the way you've described it.

[phishn]

oh well..tapes sound fine..perhaps even better aiming up then.  when someone finds an exact equation please let me know.

[Tim]

I think not pointing at the floor will definitely help your tapes...

[phishn]

"yes, so I usually keep my stand low for the same effect."

Keeping stand low= tons of crowd chatter.  FWIW, i never aim the mics with an angle that great where they would be aiming at the floor..moreso towards the subwoofer.  I always to the line of sight test before raising em.

[phishn]

cool..i'll aim em upwards at vegas..confirmed.  thanks for the input.  Of course, you never know if you don't ask.

[Tim]

have you experimented with a low stand? I think you'll find that if the music is loud enough you don't really notice the crowd..

[phishn]

ok..so if the bass is omnidirectional then I don't need to worry about aiming towards the subwoofers downward.  If I'm interpreting this right, more bass effect would be a stand at a lower height, and the mics should still point upward towards the stacks moreso than the subwoofers.

[phishn]

how low are you talking?  I'm not sure usually how high I  hoist say around 8 to 9 ft..

[phishn]

+T for all on this thread....thanks again for your input.  not only did it answer my question but made me realize what can affect sound and how it travels..such as omnidirectional bass, floor reflections, etc...guess I should focus on wave theory again...
