CHOKE-INPUT NEXUS AND CONTINUITY
MONOBLOCK AMPLIFIER
IN NORSE MYTHOLOGY, TYR WAS THE GOD OF WAR AND JUSTICE.
HE WAS ALSO ONE-ARMED BECAUSE HE WAS TRYING TO BE COOL
WITH FENRIR AND THE OTHER GODS PLAYED A TRICK ON HIM.
IN OUR SIMPLE MINDS, ONE-ARMED = MONOBLOCK.
YEAH. THAT’S WHERE COMICS GET YOU.

OWNER’S MANUAL

Tyr is a choke-input monoblock amplifier featur-
ing our Nexus™ differential topology and Conti-
nuity™ constant-transconductance output stage.
Or, in non-techy, non-buzzword-bingo terms, it’s
Schiit’s biggest and best amplifier. We’ve looked
back to the past to bring back one of its great-
est hits—the choke-input power supply —while
incorporating state-of-the-art microprocessor
oversight and protection.
INTRODUCTION
WHAT’S IN THE BOX
(1) Tyr
(1) Power cord, special super-thick edition
(0) Fanciness in the power cord
(0) Expectation the cord changes the sound
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.
GETTING STARTED
“How hard can it be getting started with a
simple speaker amp?” you may be asking. Well,
not hard at all, as long as you keep a few things
in mind.
Tyr is heavy. Not like “so heavy you need
reinforced concrete floors,” or “this amp creates
its own gravity,” but probably heavier than you
think. Each is about 55 pounds, while still being
relatively small. Be careful when lifting and
moving Tyr.
Tyr runs warm. Again, this isn’t grille-meat-
while-you-listen warm, but each Tyr runs pretty
warm. That means:
• Do not stack your Tyrs
• Ensure there’s plenty of ventilation around
each Tyr
• If you’re putting Tyrs in a cabinet, ensure at
least 2” of free airspace above each amp, and
that the cabinet is open to the air on at least
one side
• If you’re putting them directly on the ground,
thick carpet may impede airflow over the
exposed heatsinks
Also, if you like your house warm--as in, over
80 degrees F, don’t be surprised if Tyr may
need some additional fan cooling. These amps
are designed for use in typical air-conditioned
indoor temperatures.
You need one Tyr per speaker. Yes, this might
sound silly, but we actually have gotten a lot of
questions about how to connect this amplifier
to two speakers. However, Tyr is a monoblock—
which means it’s a single-channel amplifier.
Which means you need one per speaker.
You can’t “bridge” Tyr. This is a differential
amplifier, which means both speaker terminals
are “hot.” This also means you can’t use Tyr with
speakers that have a common ground between
both channels (this is very, very odd—if there are
no cables connecting your speakers together,
you’re safe).

1 & 2 Speaker Outputs. Connect a speaker to
these outputs. The right output is positive, and
left output is negative, but both are active—don’t
ground either output, or connect them together.
3 RCA Input. Connect one channel of a single-
ended source using a high-quality RCA cable.
4 Input Switch. Up selects the XLR balanced
input, down selects the RCA input.

5 XLR Input. Connect one channel of a balanced
source using a high-quality XLR cable.
6 Power Switch. Up is on. Down is off. Pretty
simple. Feel free to leave the amp on all the
time if you’d like, and use the front button to put
it into low-power Standby mode. An extra fuse is
located in the integrated fuseholder.
