you use the find delay for synchronized the mic measurement with the reference channel for measure the top ok but when you measure the sub for compared with the top you do again find delay ? (sorry for my bad english...)
Hi Timo Beckman, Thanks for sharing great video. In the Smaart Screen i can see you are using 'Mic Back' . Actually Which microphone you are using. Where is the Placement of microphone? Is in front of PA?. Thanks for your answer
The name of the mic in this screen capture was from a couple of previous capture. In this captures. The mic was about 12 to 15 meters away at the front of the set-up
Yes i used the tracking delay on the tops or on the whole system because of wind. The set-up was outside so to get a stable trace tracking delay will help a lot as will using a lot of averages (somewhere around 5 or 6 seconds). On the subs it doesn't matter to much as long as there's not to much wind hitting the mic.
Hi, great videos sir. I was wondering you added delay to both your reference and measurement signal which makes sense. But what I don't understand that why you didn't add delay in the end fire configuration with no averaging. I'd really appreciate if you explain this. Thanks !
I do not really understand the question? In the first part I Use the delay finder to synchronize Smaart as you would in any situation. The 2nd part is a little different but still the same. If you add delay to the delay finder the phase trace goes horizontal in "a desired area" in this case the x-over zone. It's just a trick to make things maybe a little easier.....
That's because you can't use the delay finder for finding delay times on sub woofers. You have to phase align sub woofers. You might want to look at this small intro in one of the blog posts at: timobeckmangeluid.wordpress.com/2017/08/13/end-fired-sub-array-with-2-fulcrum-acoustic-cs121-passive-cardioid-subs/ The first screen capture shows what i mean although in the intro i'm using a processor output. If i implement a low pass filter time changes because of group delay caused by the low pass filter. You might also take a look at this blog post: timobeckmangeluid.wordpress.com/2017/03/19/some-more-work-on-the-impuls-respons/ You can clearly see what the problem is when working in the frequency range of sub woofers.
I do not use target curves. I use common sense. If it doesn't sound the way you want it to sound keep working at it until it does. A flat line might not be what you want so adjust......
@@timobeckman4853 that's exactly what I do... The response that sounds good to me it's + 9db (subs) 0db (mids) - 6 db (highs) Wich microphone do you use for measurements?
@@timobeckman4853 great! What do you think about the ecm8000 ? On my research of true the only difference between expensive mics and this mic it's the consistent response over time and humidity\temperature changes... But are to dramatic that changes ?
@@gabrielrodriguez8200 I ask anywhere between €400 to €800 ex VAT ex Travel/hotel etc. This means i have to be sure about the gear i use so mic's i/o's etc has to be the best i can get within my budget.

The response of the Behry mic is closed to the DPA or the 7150 but it has already shown some deviation to when i first checked it. Not a big problem. Remember it's not a expensive mic so as long as it works no problem.
really help full tutorial thx sir

Really good, thanks and keep going

Hi Sir, in the first part you had the delay tracker ON when you were measuring the TOPs. Did you Off the delay tracker before you unmuted the SUB?
Yes i used the tracking delay on the tops or on the whole system because of wind. The set-up was outside so to get a stable trace tracking delay will help a lot as will using a lot of averages (somewhere around 5 or 6 seconds). On the subs it doesn't matter to much as long as there's not to much wind hitting the mic.
Hi,
Can you give me a lesson for this. I will pay for you. Please reply,
Thank you.

HI... Do you use a weighting curve when you EQ the P.A? I find out that the flat response on a line array doesn't sounds good at all
