Schiit Asgard 3 Modular Continuity Manuel utilisateur

MODULAR CONTINUITY HEADAMP & PREAMP

ASGARD IS THE CITY OF THE GODS IN NORSE MYTHOLOGY.

ASGARD IS ALSO A HEADPHONE AMP, PREAMP, AND

CAN BE A DAC OR PHONO PREAMP AS WELL.

IT’S UP TO YOU WHICH IS COOLER.

JUST DON’T EXPECT IT TO RUN COOL.

CONTINUITY AMPS RUN WARM.

HOWEVER, IT IS NOT A HOT PLATE FOR YOUR COFFEE.

ASGARD

OWNER’S MANUAL

Asgard 3 is the rst complete re-imagining of

the amp that started it all for us, way back in

June 2010. It’s the third in our line of modular

headphone amps and preamps (the others

being Jotunheim and Lyr 3). Asgard combines a

current-feedback topology and our unique

Continuity™ output stage and a modular

architecture that allows you to add a DAC,

phono preamp, or future modules. Forget the

built-in obsolescence of other amp/DACs, and

enjoy your time with Asgard 3!

INTRODUCTION

WHAT’S IN THE BOX

(1) Asgard 3

(1) Power cord

(0) Stick-on feet (they’re pressed in!)

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

qualied 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 trafc 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 qualied 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

Since this isn’t a tube amp, there’s not much you

need to get started.

If you don’t have any optional module (that is, you

bought your Asgard 3 as “just an amp,”) you just

need to connect your source and headphones:

1. Use RCA cables to connect to your analog source

to Asgard 3’s RCA inputs. Asgard 3 won’t run so well

without a source.

2. Connect headphones to the Asgard 3’s head-

phone output. Asgard 3 will run very happily without

headphones, but unless you’re using the amp as

only a desk-warmer, you’ll want headphones to con-

nect to the Asgard so you can hear something.

Note: Be careful with TRRS-terminated headphones

(usually ones with microphones)—you will need a

specic TRRS-to-TRS adapter for those.

3. If you are using Asgard 3 with external powered

monitors, you will also need RCA or RCA-to-XLR

cables to connect the preamp outputs.

If you have an optional DAC module, you may also

need to connect your digital source.

a. Use a high-quality, USB 2.0-rated cable of 2M or

less in length.

b. On some Windows machines, you may

need drivers, available at schiit.com/drivers.

If you have the optional phono card, you may also

need to connect your turntable.

a. Using short, high-quality, well-shielded cables,

connect your turntable to the phono card inputs.

b. Also connect the turntable ground to the ground

post with a short, sturdy wire.

c. Note that the phono preamp’s gain is xed at

42dB, input impedance is 47k, and load capacitance

is 100pF.

4 Input Switch. Up selects the module input (DAC

or phono). That is, if you have a module. If you

don’t have a module, up doesn’t do anything.

Down selects the rear panel analog RCA inputs.

5 Headphone Jack. Plug your headphones in here.

There ain’t no fancy balanced or fake-balanced

connectors on this amp—it delivers full power

through a standard 1/4” jack. If you have 1/8” jack

headphones, get an adapter.

Note: Plugging in headphones mutes

the preamp outputs.

1 Vents. Asgard 3 runs 500mW of Class A bias

(for 32 ohm loads), so it runs plenty warm. Don’t

block these vents, and don’t spill your Chardonnay

in them, either. Nor coffee. Nor Coke. Or let your

cat throw up in it. You get the basic idea, right?

2 Volume Knob. Turn it to the right to make

the music louder. Stop before it hurts. Or your

headphones smoke. Seriously.

3 Gain Switch. Up is high gain. Down is low gain.

No surprises here. Use low gain for sensitive

headphones—that is, if you hear hiss or don’t have

enough volume control range.

CONTROLS

4 Preamp Output. Connect these to your powered

monitors or speaker power amplier with high-

quality RCA cables. If your powered monitors

have XLR inputs, you can use RCA to XLR cables

to connect to them.

5 On-Off Switch. Up is on. Down is off. Nothing

very complicated here.

6 AC Input. Plug the power cord in here. Plug the

other end into an outlet of the correct voltage.

Trying to run a 115V product on 230V will blow

the fuse and generally make for a bad, bad day.

1 Card Input. If you have a module installed, the

input for the module will be here. If you don’t have

a module installed, it will be covered.

2 Ground Lug. If you have a phono card installed,

there will be a ground lug here. You will probably

need to connect it to your turntable ground for

minimum hum.

3 RCA Input. Connect your source here with

high-quality RCA cables. Alternately, you can

use cheapie cables, but if you have a problem,

remember that we’ll ask you to check cables rst.

CONNECTIONS

I hear hum through the headphones.

You may have a ground loop. To x a ground loop,

try a ground loop isolator or an EbTech HumX. If

it’s low-level hum and noise, you can use Lo gain

to reduce it.

There’s no sound for a while after I turn it on.

That’s perfectly normal. Asgard 3 has a built in

start-up delay (and instant shut-down.) It’s set to

20-30 seconds to let the output stabilize.

There’s no sound with the input switch

in the top position.

Do you have the optional DAC or phono card? If

you don’t, you won’t get any sound.

I get weird noises when I use my cheapie earbuds

that have volume control on them.

Right. Those are TRRS headphones. You need a

TRRS to TRS adapter for those. Continuing to use

TRRS headphones without the right adapter can

cause functional problems as well. Seriously, get

the right adapter.

FAQ

Can I leave Asgard 3 on all the time?

You can. It won’t catch on re or anything, even

though it runs warm.

My computer doesn’t see the DAC card via USB,

what’s up?

Go to schiit.com/faq/dac-problems and

schiit.com/faq/usb-problems for digital system

troubleshooting.

I’m having hiss and hum from the phono card,

how do I x that?

Start at schiit.com/faq/phono-problems for phono

troubleshooting tips.

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.
