FREYA
owner’S manUal
The following is required by the roughly 9,542 government agencies
and regulations we have to comply with. If you have some common
sense, they should seem pretty straightforward. In any case, read
these instructions before proceeding farther, follow all instructions, and heed
all warnings. Or else!
1. If you don’t know how to install audio devices, get a qualified professional
to help.
2. Never use this device near water, and clean only with a
dry cloth.
3. Assure adequate ventilation, do not block any ventilation openings, or place
near heat sources.
4. Use only the supplied power cord or suitable replacement. Route cords away
from traffic areas and protect them from being pinched. Unplug the cord from
the outlet if the apparatus is unused for a long period of time.
5. To prevent electric shock, do not use the plug with an
extension cord, receptacle, or outlet unless blades can be
fully inserted.
6. Refer all servicing to qualified service personnel. Service is required when
the device has been damaged, including cord or plug damage, liquid has been
spilled or objects have fallen into the device, the device has been exposed to
rain or moisture, does not operate normally, or has been dropped.
WARNING: TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE THIS DEVICE TO RAIN OR
MOISTURE.
INTRODUCTION
Freya is a no-compromise, ultra-high-end balanced preamp clever-
ly disguised by a low price tag. You won’t find any volume-control
chips or other shortcuts in Freya—just uber-quality techniques like
a relay-switched stepped attenuator and all-triode gain stage—you
know, just like what’s used in the most expensive audio gear.

(0) Wall-warts (they’re not needed)
CAUTION! Dangerous voltages inside!
1. Before plugging in the preamp, insert
the tubes. Carefully align the key in the
tube base to the notch in the tube socket
for each tube. It doesn’t matter which tube
goes where—all tubes in Freya are the same type.
2. Ensure tubes are well-seated. Push down firmly until the tube is
seated on the tube socket. This may take a fair amount of force.
3. Plug it in and turn it on. The tubes will glow after a few
seconds, and the microprocessor will connect the output after
about 40 seconds.
4. Connect your sources.
Connect up to 5 sources
to Freya’s balanced and
single-ended inputs.
5. Connect the output. Connect
the output of Freya to your amp or
amps using XLR or RCA cables.
6. Ensure the volume is turned down if you’re using Freya for the
first time. You don’t want any big surprises!
7. Power it up, turn it up, and enjoy your music!
TUBES
replacInG tUbeS
Freya accommodates any 6SN7, 6N8S, or 5692 tube type.
6SL7, 6N9S, and equivalent types also work, but will have higher
distortion and higher output impedance.
The right tubes are for the differential voltage gain stage. The left
tubes are for the cathode follower output stage. All tubes are of
the same type on Freya.
To replace or swap tubes:
1. Turn off and unplug the preamp. Wait a while for the tube to
cool. Seriously, these suckers are pretty hot.
2. Carefully extract the tube by gently rocking it back and forth
and pulling upwards.
3. Carefully insert the replacement tube. Align the key to the notch
and press down firmly until the tube is seated.
4. Plug the preamp back in and turn it on.
