https://www.admess.de/ap-promo-30-2024/ No idea if it's international or just from the distributor. To be honest I'm happy with the generator of my 515. When you don't build absolute super high end AD converters you should be fine. p.s.: 25% at AP.com and 10% at lower ones or R&S UPV.

Btw not sure if it is already mentioned - AP gives a 30% bonus until 2024 when you trade in an 2700 analyser. That's a good amount when you buy a 555! They will also take smaller ones (ATS-1 etc) but with less price reductions. It's not the case :cool: When the unit doesn't perform to the...

A GOOD switched power supply is better as the conventional 50/60 Hz transformer. You always have some residuals of the main power frequencies with transformer power supplies, switched mode ones push these out of the audible range. And properly done they have no downsides. But not that easy to...

Is it possible to connect the computer with HDMI to your receiver and select different channels for measurement in REW? How did you achieve this? I have a 7.1.2 configuration at the moment and would be also interested how the calibration happens in my difficult room. Your Dirac correction looks...

I have an 56R at the input cause that was laying around :facepalm: and it's at it's lowest gain setting. Unsurprisingly it rises with higher input ranges ... but I never protocoled how quickly.

That's interesting. The smaller APs I know (515, 525) all outperform their specs, my 515 is in terms of input noise better as the 525 datasheet. (1,1uV, 0,83uV(A) - spec of 525 is <1,3uV, spec of 515 <1,4uV) All of the 515/525 have input noise in this range (cause this was a discussion once with...

I know from one of my customers they just NEED to calibrate gear which is involved into production once a year. No matter if it's needed or makes sense - it's not allowed to be switched on without the correct calibration sticker. Someone is making a lot of money with calibration there ... Of...

With the actual problems with Denon/Marantz I would not buy one of these amps in the next few month ... https://www.audiosciencereview.com/forum/index.php?threads/denon-marantz-the-end-is-near.58647/

Can you give some more information about that? How is the "interface" on the PC? Virtual sound card or ASIO pluging or something different? How many channels are supported? I will start rebuilding my listening and mixing room soon, with Dirac ART running on the computer I would plan 2-4 subs...

Your 2700 machine will not stop working suddenly. They didn't got any updates for years now, the software is ancient. When you need regular calibration you surely switched to a newer model a while ago. So they announced to not repair 20+ year old units any more. 2722 and it's brothers...

Which Wilson Alexia has 0,9R impedance? This one goes down to 2,0R, the new one is specified with 2,6 or so impedance minimum. https://www.stereophile.com/content/wilson-audio-specialties-alexia-loudspeaker-measurements Building a speaker with 0,9ohm impedance on PURPOSE ... :oops:

You go digital from KH750 to both KH120ii. Then you can go analog or digital into KH750 from your source. It really makes sense to also connect KH750 with digital connection to your system! I use my RME for studio but recently bought the WiiM preamp for my office and 2 KH120ii, there are more...

Klippel Measurements - do I see that right that there is no room correction at all/anechoic measurement for THD? There is +-5dB influence of the room >100Hz and -30dB(!!!) at 92Hz. The % THD scale is only from 100Hz upwards (guess why ...) and pretty nonsense under 300Hz. Now I know why they...

I would have preferred to not have a pronunciation in the 3-5kHz area. And maybe a little boost >10kHz. But EQing is easy nowadays and the rest of the implementation ist very nicely done. Looking forward to what price they can make in the European market.

You use MA1 with the 750 and still can hear the sub location? 120 or 120ii? What cross over frequency? At all volumes? Normally you hear a sub located when the level is WAY to high, the crossover doesn't work properly cause level is to high and phase is off or it distorts already. Or cross...

Yes - they are very slow with their software :rolleyes: I always laughed about "Germans can't do Software" but ... They also need a network volume and monitor control unit and of course ATMOS is the way to go for new studios, they need an easy configuration and setup recall tool. Switch...

Next version they just need to implement a low frequency cancellation system with these 8 subs :cool: or at least a double array function with automated correction ... I'm sure they have the Knowhow and this would set them apart in the Pro industry and show the quality of their MA1 system. They...

I did plenty of measuring with sine sweeps with the KH120ii and never experienced such a behaviour around 50Hz. It will start with noises at way higher levels like every ported system.

Just remeasure and write over the settings? You should be able to set the sensitivity also in network mode similar to the sensitivity switch on the back?

That's pretty easy to decide - cause ATMOS tells you what to do to stay within the norm so the decoder knows what to do ;-) Search for "Atmos-installation-guidelines-....pfd" 5.1.2 or 7.1.2 is with 2 top middle overhead speakers which are 80° over your head (so a liittle in front of you) with...
