Could be, I have also seen an older websize under the SZAPTK brand. Usually when Chinese people mention the country of origin they mean it's imported, since they're saying "German Klippel" it implies it's from Klippel. But they're not an official klippel reseller.

I don't know what's going on, but this company is certainly interesting... http://www.abtec.cn/product/60.html Anyone knows about it?

Things I like - Auto calibration. it does a frequency response and a gain-calibration automatically. Seems to first one a fixed-voltage AC source to calibrate the DAC, then do a frequency response, and then calibrate the ADC. - Autoscaling works well - the separation by task. Frequency response...

I'll make a video in the next few days

Yeah I have it. You do a couple of impedance measurements, and then press an icon with a weight on it do calculate the TS parameters using the added mass method. I believe it's possible to use the QC box to calculate impedance measurements at different voltages.

Hi Fellas, I'm testing a Clio 12 this week, and the related QC (amp) box. Any questions? Any tests you'd like me to run?

hi, Any news on this project ?

Hi, I’m very curious to see how the input stage of the CLIO 12 is designed. Anyone is willing to post some pictures of what’s inside their unit? Any other audio analyzer input stage welcome.

Various items under NDA, so the picture is a clean workbench instead.

Ok so I was curious and I bought them. Findings: Compared to HD600, ER4XR, ER4XR eqed as per Oratory1990: - Quite a bit of bass, but that's expected - Too much treble and missing mids. pop music sounds terrible. other genres are fine. Definitely not happy so far, but will try with different...

It can get pretty wild sometimes... here are 6 wires soldered on a sensor for an experimental medical device.

Just wanted to pitch in. I'm an EE designing tablet computers that enable disabled people to communicate. One of the issues I encountered is audio is a low priority for many companies, and tools such as audio analyzers are very expensive and specialised. REW has been an absolute blessing...
