FAQ
I hear hum through the headphones, what
do I do to fix it?
You may have a ground loop. To fix a ground loop,
try a ground loop isolator or an EbTech HumX.
There's no sound for a while after I turn
Jotunheim R on.
That's perfectly normal. Jotunheim delays the
headphone output for 25-35 seconds after you
first turn the amp on to allow it to stabilize.
There's no sound with the input switch
in the top position.
Do you have the optional DAC? If you don't, you
won't get any sound.
The Jotunheim R clicks and mutes, then turns
back on again, then clicks and mutes again.
You're triggering the overcurrent protection.
Check your cables for shorts.Jotunheim R is
intended for use only with Raal/Requisite head-
phones, and should not be used with adapters
for other headphone types, which may short the
output and cause it to go into protection.
The Jotunheim clicks and mutes, and stays off
for several minutes, and it's really hot.
You're triggering the overtemperature protection.
Reduce the output level or increase ventilation.
Also see the previous comment about not using
adapters for other headphones, and checking your
cables for shorts.
My Windows computer doesn't see the DAC.

doesn't see the DAC.

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.
