No time to explain but here are the screen captures…..

SMAART I/O ended up displaying a 0.1dB offset to 94dB but was consistent over the full “gain range”. The Evo4 and the UA1010 stayed within level 1 specs AFAIK (i never read those spec but this is from “hear say”).

For now 2 video’s and some data….More to follow

Hi Guys just playing around with the new Smaart V9 Suite…. Enjoy

This trace is for reference purposes only . I always take when given the chance a trace up close for reference purposes so that i know what to look for when all are up in the air and the mic is far away from the array . Acoustics can blur the far field trace as you can see in the next screen-shot from the far field mic .

A simulation on a end fired sub array . First free field and after that with walls .

Don’t you just love them walls .

So this is the last measurement job i did . Just the first day though . Screenshots are made with the SIM3 set-up and data viewer .

So as a follow-up on the cardioid SUB files i posted some time ago https://timobeckmangeluid.wordpress.com/2011/11/08/end-fired-sub-array-only-in-english/

There are a few things i did not post about and among them is the difference between subs in a conventional Left & Right set-up and subs in a line . So here we go………

So anybody remember that movie BACK TO THE FUTURE ? One of my most favourite scenes next to the “this amp goes to eleven” from Spinal Tap is the scene where Michael J Fox blows one of the biggest loudspeakers in this world to bits . The story tells about a guy travelling back & forth in time in a delorean sports car . The car is a time machine because it has a FLUX-capacitor build in . Because of power problems it needs a lightning strike to get back to the future . So what does “BACK TO THE FUTURE” have to do with audio ?

In the last few posts there were descriptions of cardiod sub array’s .

Turns out you need more processing and amplifiers to build them , knowledge to put them to good use (so you need a system technician) , measurement equipment for verification and calibration and a number of other things so in the end it all comes down to money . These set-ups are more expensive .

This is the last of the cardioid  sub arrays I’ll explain . If there’s no room for a end fired or a reverse end fired sub array or the budget only allows 3 subs a side and there’s no room for a end fired line of 3 subs there’s 1 array you can try . The CSA (according to some developed by D&B) .
