Kemper Amps Forum

Thanks bro! I contacted them via email...

Quoted from "schneidas"

Ok, I tried and tried with the S/Pdif out on the KPA today.
Gain maxed out, volume maxed out, MV maxed out - everything super hot.. no signal gets to my soundcard.

Is there a digital out volume I'm missing somewhere hidden in the KPA menu?

I guess the problem is, that your audio interface is set to something different than 44100 Hz. Since the SPDIF input of the KPA is not working yet, the KPA can only act as SPDIF Master, not as Slave. So your Audio Interface should be set as slave. If that is not possible, try to set to 44100 Hz manually.

My SPDIF output works pretty good.

Actually, I do have the soundcard (M_Audio Delta 2496) set to 44100 Hz. It synchronizes with the S/Pdif out of the Kemper.
When I try to set the Hz on the soundcard to anything else (48Khz, 96Khz), it just drops back to 44100 Hz.

Word from Kemper is that the S/PDif issue will be fixed in an update soon... and it should work for everybody then.

This may be related but when I connect S/PDIF OUT to my Axe-fx II S/PDIF IN it gives me a "no input clock" error.
I know they are 'rival' products but it would be cool to connect the 2.
Will the fixes allow for clocking at 48khz? and allow me to run the Axe-fx as the sound-card / post-effects processor.

I already made a suggestion to the kemper guys via email to be able to configure the output signal of the SPDIF output. For those who intend to use the KPA for reamping it would be awesome to be able to output the dry direct output signal of the guitar out of the SPDIF out. That way you would not have to use a DI Box and any further A/D and impedance conversions would not be necessary anymore. i could imagine a config dialog for the SPDIF output routing in the following way:

1. normal Amp output
2. dry DI output
3. mixed mode. Left side: amp output, right side DI output

I would especially love the third mode because it would allow you to record both signals in one pass. You would just create two mono tracks in your DAW and route the left and right sides accordingly.
