Playing around with a couple of SUBS ;-)   2 comments

Most of the time the word SUB gets everybody’s attention. Played around with a couple of them today outside……

SUBS SUBS SUBS ;-)

First here’s a link to a post i did more then a year ago:

CSA post januari 2016

The screen capture below sort of shows the same thing as explained in the blog post.

The channels you want to keep your eyes on would be both the far field front (orange) and far field back (pinkish) mic’s. These would be the bottom traces in the screen capture.

Settings on the apex processor would be:

*First> front sub 0dB back sub -6dB +/- 3.5ms delay and polarity reversal. This will give the deepest cancels in the near field of the array.

*Second> front sub 0dB back sub -0.5dB +/- 3.5ms delay and polarity reversal. This will give the deepest cancels in the far field of the array.

A surprising thing for me while doing this measurement: normally doing this indoors with boundaries (walls ceiling etc.) i most of the time end up with 4.5-ish ms delay and now i end up with less……..Lesson learned again. (Mapp gives about the same value 😉 ).

On Youtube

I’ll add more to this post but i’m out of time now. Enjoy
