Mac OSX + Chrome user here, everything works fine.

Digi 192 user here also. Works fine when you set the clock source to SPDIF in PT. I also get pops / crackles if I set the clock source to anything else. I use both SPDIF in and out.

This is in Italy, nice price - http://www.essemusic.it/produc…R-Profiling-Amplifier.php

I have no experience with them so cannot comment on that

Thanks for that perfect prove!
You see the green line below the purple line just because the volume of the second track might have been a fraction of a decibel lower.
If not we wouldn't have seen the green line at all. A perfect match.

If it were just a matter of levels, wouldn't the red line then still be perfectly straight?

He Paco ¡muchas gracias!

He ReDRuM, in case you are Tony: Isn't the KPA a Weird Weapon?

Have no idea what you're talking about. Not Tony, sorry

What did you do? Did you change the phase in one of them and then try to cancel each other being the resultant the difference between both of them? If so I don't think it is that simple.

It is that simple but not with variable latency Also, resulting file here definitely shows that the null test is not valid. There should be "less" of the resulting signal, since everyone agrees that the differences are subtle

Ok. Did a test with Morgan AC20 profile in firmwares 1.5.4 and 1.6.0. Reamped through spdif no changes in configuration. Inverted one of the two tracks and this is what you get when you sum both. Isn't this the difference between both tracks?

I'm not sure, but I think that KPA's variable latency makes a null test meaningless.

Great tone! Profile please!

Unbelievable that this has to be requested.

This is quite weird. So Kemper staff is basically telling us we don't need our reamp boxes for reamping?

I was trying to figure out what was the best way to "insert" a real stomp box into the signal flow of the KPA when feeding the S/PDIF input with the clean DI track from the DAW. What was confusing is that the manual suggests using the same outputs for feeding everything, like impedance doesn't matter.

If the KPA's I/O's are somehow "smart" then this needs to be clearly stated and some more technical information needs to be provided to us more technically inclined types.

I find this story similar to the "Clean sense / distortion sense" story. The manual says what to do and how to use it. But I don't feel comfortable unless I know the signal flow.

Same goes for the I/O's. Sometimes in the studio I cannot trust my ears and do tests to "check that the sound is OK". I need to know what to expect so that I don't have to waste time testing stuff.

I think that this is one thing that the manual lacks. More technical info.

I would also like to know some of these more technical details about the KPA's signal handling capabilities.

From what i know those converters only transform light into voltage and vice versa. So the binary data should stay the same which means there is no change at all.

I would really appreciate it if mr. Kemper could confirm that using one of these converters is not going to "degrade" the KPA experience in any way

The slave option needs to be done. I have a fairly complex studio setup and I really don't like using the KPA as the master for the whole system.

So,

Same boat... I plan on getting the maudio converter box. Right now I'm going in the hi-z input and I must say it still sounds pretty darn good

I'm sure it does... Still, going for the coax S/PDIF for the KPA seems like a weird decision.

Hi guys! Just curious... Both the Motu Track 16 and the RME Babyface have the optical S/PDIF (Toslink) connections while the KPA uses the coax (chinch) connections. Are you guys using some converters to get around this limitation?

I got my KPA yesterday and was really disappointed to find the coax S/PDIF connections (Babyface user here). I know, I should have checked before buying, but it just slipped under my radar

Also, does anyone know why the decision to go for the coax S/PDIF on the KPA since it seems to me that most audio interfaces these days use the optical S/PDIF. Especially the "project studio", "lone musician ( ) " interfaces.
