I missed the tick tock tick tock when i went to your place bro, probably not silence enough

Lol... sorry couldn’t chat longer that day, u saw how the hall looked like that day during the installation work... will catch up again next time, how is your SMT treating you ?

Are u enjoying it ? What quality did it bring to your set up ?

Here is one video I saw recently

Hi,

For the PLiXiR Elite BAC 3000 he is using, it is the horizontal version.  We also make them now in full UK outlets as well. 

Thank you.

James.
Nice !!!

See this, veritune smt tuning.

"Veritune" Helmholtz resonators- Adjustable helmholtz resonators allow for specific targeting of modal problems from 16-100 Hz.

Its effective! Placed at locations below the SMT wings

Awesome stuff this SMT

Here is another way of measuring the noise floor levels if you have an iphone , download this free app called decibel x





A quick way to measure, u can look at the peak and min noise floor... above is the noise floor in a badminton hall taken just now...

I’ll post shortly on using the REW method ... hope that helps..

The above is the room noise floor now, after the acoustics work, nice levels averaging 30db in the hall, that peak at 35hz is the sound of the fan in the room

Above 1khz, it’s all down below 10db, that shows the equipment connected all has very Low noise, great job from the Plixir Elite BAC 3000! Hardly any electrical noise in the chain...

2019 achievement unlocked !

Question -- when you did the above measurement, what was the FFT length, and was the "Adjust RTA levels" checked or unchecked?
I used 131k FFT length, and with Adjust RTA levels checked, my room is about 48dB average.

Here is the settings I’ve used, with axis 10hz-20,000khz and 0-80db on RTA to measure the noise floor, I used 8 averages

Thank you.
I notice when the "Adjust RTA Levels" is checked -- the measurement is pretty close to what I see on the iPhone DecibelX app.
I think the "Adjust RTA Levels" need to be checked for noise floor measurement. What do you think?

Use this option when measuring the subs on the fly, using a pink periodic test tone from rew signal generator, then u can choose this option.

When everything is silent, look at the mic levels A weighting Fast... it will display the average noise floor levels in the room

SMT at Procella's amazing ATMOS 24.4.10  HT set up at the  ISE show in Amsterdam last week !
40 custom cardboard Wings togheter with 40 Crystal ceiling diffusors was installed. Amazing stuff really.








Last night I rewatched the book of Eli, the gun shooting demo clips, superb decay , suddenly I have a “Phantom Wide” channel in my system now, feels very immersive in a bubble now. The widths are much “ enhanced” and “depth” from the sound of bullets is unbelievable and they decay off nicely... feels really awesome

I gotta a shock a few times and thought something dropped off from my from surrounds

Use this setting when you want to adjust subwoofers using the RTA on the fly. This method is good when determining the best combinations between two subwoofers. Play a pink pn (periodic noise) while adjusting the distance on avr/phase controls and look at the big screen for its interaction and adjust the distance/phase until you find the perfect blend.

There is also a DB meter above that shows you the sum of both subs SPL as you adjust the distance/phase
