FAQ
I hear hum through the headphones.
You may have a ground loop. To fix a ground loop,
try a ground loop isolator or an EbTech HumX. If
it's low-level hum and noise, you can use Lo gain
to reduce it.
There's no sound for a while after I turn it on.
That's perfectly normal. Asgard 3 has a built in
start-up delay (and instant shut-down.) It's set to
20-30 seconds to let the output stabilize.
There's no sound with the input switch
in the top position.
Do you have the optional DAC or phono card? If
you don't, you won't get any sound.
I get weird noises when I use my cheapie earbuds
that have volume control on them.
Right. Those are TRRS headphones. You need a
TRRS to TRS adapter for those. Continuing to use
TRRS headphones without the right adapter can
cause functional problems as well. Seriously, get
the right adapter.
Can I leave Asgard 3 on all the time?
You can. It won't catch on fire or anything, even
though it runs warm.
My computer doesn't see the DAC card via USB,
what's up?

I'm having hiss and hum from the phono card,
how do I fix that?

troubleshooting tips.
It doesn't turn on, what do I do?
Plug it in to a different AC socket. Ensure you are
not currently in a blackout. Then email us if it still
doesn't work.
