Comment on A sample soundcard measurement – Edirol UA-25EX by Simon https://johnr.hifizine.com/2012/09/a-sample-soundcard-measurement-edirol-ua-25ex/#comment-67271 Tue, 28 May 2019 23:15:31 +0000 http://johnr.hifizine.com/?p=127#comment-67271 Looks like distortion caused by the wrong capacitor dielectric used in circuit around the opamps. Likely X7R dielectric when C0G/NPO should be used. Distortion in this case is proportional to the voltage across the capacitor and so it scales down rapidly when viewed on a log decibel graph (every -6dB is half voltage).

A bit of DIY could be very productive.

Comment on Focusrite Scarlett 2i2 measurements by John Reekie https://johnr.hifizine.com/2012/09/focusrite-scarlett-2i2-measurements/#comment-67270 Fri, 28 Dec 2018 14:04:52 +0000 http://johnr.hifizine.com/?p=185#comment-67270 Hello, sorry for the late reply. I have not used the Solo but I assume it would work fine for measurements. However, it won’t be able to do a timing loopback which is necessary for accurate acoustic timing measurements. There are workarounds but none as convenient as just doing the loopback.

Comment on Focusrite Scarlett 2i2 measurements by Francesco https://johnr.hifizine.com/2012/09/focusrite-scarlett-2i2-measurements/#comment-67269 Fri, 16 Nov 2018 08:27:12 +0000 http://johnr.hifizine.com/?p=185#comment-67269 Hello, thank you for posting this, it is very useful. I have a question: would the Scarlett Solo be suitable for measurements as well? It’s the smaller sister, avalaible for a little less money…

No, there was some issue between the USB on the Pi and the miniDSP and I never really followed up since. I need to try it with the latest firmware in case something has changed. I suppose TOSLINK might work with a suitable HAT but haven’t tried it.

Comment on SB29RDC on Pellegrene waveguide by John Reekie https://johnr.hifizine.com/2014/04/sb29rdc-on-pellegrene-waveguide/#comment-67266 Thu, 26 Apr 2018 12:28:33 +0000 http://johnr.hifizine.com/?p=720#comment-67266 Hi David, depending on where you are you may be able to get these, but I really wouldn’t know how well they would fit/work with the SB29 – https://www.diysoundgroup.com/speaker-parts/speaker-components/seos-waveguides/seos-8-tweeter.html

Comment on SB29RDC on Pellegrene waveguide by David Eisan https://johnr.hifizine.com/2014/04/sb29rdc-on-pellegrene-waveguide/#comment-67265 Mon, 23 Apr 2018 16:29:17 +0000 http://johnr.hifizine.com/?p=720#comment-67265 I too am looking for a waveguide for SB Acoustics SB29RDC-C000.

I tried the Visaton WG148R and the throat is a little small, it interferes with the tweeter surround.

Any suggestions?

David
