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 straightfor-
ward. 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 qualied profes-
sional 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 trac 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 qualied 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.

Yggdrasil+ is simply the ultimate Schiit DAC—and maybe
the ultimate DAC, period. With insane design throughout,
from the choke-input power supply to unique time- and
frequency-domain digital lter, to complete modularity
that ensures you’re ready for the future, Yggdrasil is a
true agship. Enjoy!

1 Connect the XLR outputs to your
balanced preamp or integrated amp.
Use good-quality XLR cables. We do not
recommend connecting directly to your
amp, even if you are using digital volume
control on your source.
2 If you don’t have XLR inputs on your
preamp, connect the RCA outputs to your
preamp or integrated amp. Two sets of
outputs are provided. All outputs—balanced
and single-ended—are active at the same

time, so feel free to connect to subwoofers
and other devices as well as a preamp or
integrated.
3 Connect the Unison USB™ input to
your streamer, computer, or tablet. Use
a short (2m or less), USB 2.0-rated cable.
Depending on your source, you may need
an A-B, C-B, or Mini-B USB cable.
4 Connect the optical input with a short
(3m or less), high-quality Toslink-style
cable. Some lower-quality cables,
especially long cables, will not be able to
support 176K and 192K sample rates.
5 Connect the RCA coaxial digital input
with a high-quality 75 ohm coaxial cable.
6 Connect the BNC input with a 75 ohm co-
axial cable to a BNC digital source, (if you
have one, these seem to be rare these days!
7 Connect the AES/EBU input with a high-
quality digital-rated XLR cable. If you aren’t
using Unison USB, we highly recommend
AES/EBU.
8 Plug in the power cord. Use the supplied
IEC cord. The other end goes in the wall.
Yep, we know you knew that. And yes, you
can use another power cord if it makes you
feel better.
9 Turn on the power using the power
switch. Up for on, down for off. Very
simple. You can leave Yggdrasil on all the
time if you’d like, or turn it on and off as
you use it.

4 This is lit when phase is inverted. Press
button 2 to go back to normal phase.
5 This is lit when you’re in NOS mode.
Press and hold button 2 to leave NOS mode
6 The Sample Rate LEDs indicate what
format is coming in to Yggy—44.1K or 48K,
plus the multiple (1, 2, 4, or 8X.)
7 The Input LEDs show what input you’ve
selected. Hopefully it doesn’t show more
than one.
1 Push the Input Select button to pick your
input. Miss your input? Keep pressing.
2 Use the Phase & Mode button to switch
absolute phase and to use NOS mode.
Push once, quickly, to invert the phase, or
to leave inverted phase mode. Push and
hold to enter or leave NOS mode.
3 Use the Mute button to mute output.
Press and hold to mute. When in mute, LED

8 The Low Quality Source lights when
clock regeneration must loosen its
algorithm due to poor source. AKA the
“buy better gear” light. You should pretty
much never see this light. If you do, check
your source and cables.
9 This lights when muted. Press button 3
to unmute. It also ashes when Yggdrasil
is rst turned on and it’s doing self-checks.
10 This is the remote control sensor. Don’t
block it if you want the remote to work.

The remote allows you to cycle
through inputs, mute the output,
and invert the output.
Changing the Battery
1. Push the remote open by inserting the
end of an open paper clip into the hole in
the back and pressing rmly.
3. Replace the battery inside with one of
the same type.
4. Reassemble the remote by rst inserting

Yggdrasil+ is upgradable via its modular
design—the USB Input, SPDIF Input, DSP,
and DAC/Analog cards are all updatable.
When it’s time for your upgrade, we’ve taken great care
to ensure that Yggdrasil+ won’t have to come back to us.
However, if you want the condence of a factory-installed
upgrade, the Schiit Upgrade Queueing system ensures
you can keep your DAC until the moment we’re ready to
do the upgrade.
If you’d like to be the rst to know about upgrades as they
become available, sign up on the SPAM link on our site.
UPGRADES
I hear hum from Yggdrasil+. What do I do?
Yggdrasil’s noise oor is insanely low, so it’s most likely a
ground loop. To x a ground loop, try a HumX or a ground
loop isolator.
Hey, this thing clicks between songs/between inputs/etc!
Yes, it does.
Care to explain why, smartass?
Sure. That’s the muting relay engaging when there’s no
input. Many computer sources turn off the digital audio out-
put between songs and when changing sampling rates. We
went with a muting relay because it’s the best way to ensure
there are no clicks or pops when the input is unlocked. But
it does click a bit.
It takes a few seconds to change inputs and play music!
Yes, it does. Yggdrasil+ is doing a lot when you change
inputs. It’s actually looking at the quality of the input signal
and making a decision on which clock regeneration system
to use, as well as which clock frequency is appropriate to
the sampling rate. It’s a hell of a job, so it can take a little
while to lock in.
My computer doesn’t see the Yggdrasil via USB. What’s up?
It depends on the computer. Some Mac and PC operat-
ing systems have draconian restrictions on the amount of
power their USB ports can provide. Check schiit.com/faq/
USB-problems for some possible solutions.
FAQ
How do I install the Windows USB drivers?
No modern Windows computer needs drivers. We are fully
UAC2 compliant, so we work with Windows, Mac, Linux
(most streamers), Android, and iOS.
What if I’m still having glitches or intermittent
connectivity when connected to a computer?
Start at schiit.com/faq/DAC-problems for troubleshooting.
I don’t get any sound from Yggdrasil+!
Are your sources on? Check those rst. If you’re using a
computer source, ensure that your computer’s sound out-
put is set to go to the Yggdrasil via SPDIF or USB in BOTH
the Control Panel/System Preferences AND your music
player software.
Can I leave my Yggdrasil on all the time?
Sure, if you want to. In fact, we leave all our DACs on all the
time. It won’t hurt anything.
So when do I get the next upgrade from you?
Make sure you’re on the mailing list, and we’ll let you know
when we’ve released new USB or analog boards.
It doesn’t turn on, what do I do?
Plug it in to a different AC socket. Ensure you are not cur-
rently in a blackout. Then email us if it still doesn’t turn on.
