Title: Direction of omnis
Post by: blu666z on July 26, 2004, 01:05:33 AM

This will be my last omni question for a while I swear.  I understand that by defintion omnis pick up 360deg, but does the angle of the cap to the stack change the frequency pickup?  ie. I'm working on a croakie stealth setup....before the sun goes down(sunglasses on my face), my caps will be parallel to the ground.  After sunset(move to sunglasses up on the head), the caps will be 45deg to the ground.  Will there be an obvious sonic difference on the tape?

Onmis do tend to exibit directional characeristics in the high end, look to the published polar pattern plot for specifics. I'm not sure we can answer your question based on angle to the ground, rather, the important question is how will they be pointed in relation to the stacks?

Horizontal angle wouldn't change only vertical.

a tad, yes. the 45 deg. up will sound a bit "airier," perhaps. i'd choose that over stickin 'em straight forward.

i ran my omni's for oar a bit differently...  i was about 20ft off the stack 13' up.  but i mounted the mics facing eachother w/ a 10" split.

i'm real anxious to hear how it came out once it's converted.

are more directional ast higher frequencies.  based upon this when i run my TL's omnis i always point the caps towards the stacks or right at them.  better , more even frequency pickup that way.

edit: so yeah don't point your mics towards the ground ;)
