I hear hum, what do I do?
A small amount of hum when using the
differential tube output stage may occur
with some tubes. Try other tubes. The noise
should not be audible from the listening
position in most typical systems.
No, I mean, I have a LOT of hum!
You may have a ground loop. Try a ground
loop isolator or a device like the EbTech
HumX to eliminate the ground loop.
There’s no sound for a while after I turn
Freya on, and the lights ash.
That’s perfectly normal. Freya delays the
output for 20-40 seconds after you rst turn
the preamp on for self-checks.
What’s with the clicking noises when I turn
the volume?
That’s the sound of the mechanical relays in
the relay-switched stepped attenuator. Also
normal.
FAQ
The Status light ashes when I select tube
output mode.
Yes, this is normal. Freya only powers up
the tubes when they are in use. You can
cancel tube start-up if you select a different
output mode within 5 seconds of selecting
tube output; this allows you to skip back
and forth between passive and differential
buffer quickly.
Can I use both outputs at the same time?
Most of the time, yes. If you have products
that short the input when turned off, then
that can cause distortion.
I have the volume all the way down and still
hear faint music.
Yes, that is normal with a relay attenuator.
If it’s bothersome, hit the Mute button to
completely mute the preamp.
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.
