Schiit Jotunheim R Bedienungsanleitung

DIRECT DRIVE RIBBON HEADPHONE AMP

IN NORSE MYTHOLOGY, JOTUNHEIM IS THE LAND OF THE GIANTS.

OUR JOTUNHEIM R ISN’T EXACTLY GIANT IN DIMENSIONS.

BUT IT HAS GIANT CURRENT OUTPUT FOR LOW-IMPEDANCE RIBBONS!

THE WORLD’S FIRST AND ONLY DIRECT DRIVE RIBBON HEADPHONE AMP

DRAMATICALLY SIMPLIFIES YOUR SYSTEM.

JOTUNHEIM R

OWNER’S MANUAL

Jotunheim R is the world’s rst and only direct-

drive ribbon headphone amplier. Created for the

demanding Raal/Requisite ribbon headphones,

Jotunheim R cranks out up to 14A RMS per

channel at visible clipping—plenty to run your

Raals. No speaker amp, no interface box, just

pure drive...in a tiny, convenient package.

INTRODUCTION

WHAT’S IN THE BOX

(1) Jotunheim R

(1) Power cord

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

1. If you chose Jotunheim R as an amplier only

(no DAC), simply:

a. Plug it in with the supplied power cord

b. Connect an input or inputs to the XLR and RCA

inputs on back.

c. Turn on the amp, select the correct input, wait

25-35 seconds for the relay protection to engage

the output, and enjoy.

2. If you chose Jotunheim R with the internal

True Multibit DAC card, you’ll also need to con-

nect your source to the DAC module.

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

or less in length.

b. If you are using a version of Windows prior

to Windows 10, you may have to install drivers,

which are available at schiit.com/drivers.

ABOUT UPGRADES

Additional cards for Jotunheim R may be

released in the future. When this happens, you

can return the Jotunheim to us to have the card

installed, or have it installed by a qualied elec-

tronic tech. 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.

3 Preamp Enable. Up turns on the passive preamp

outputs, off turns them off. Note: the preamp is

passive, it has no gain and doesn’t convert bal-

anced to SE or vice-versa.

4 Volume Knob. Turn it to the right to make the

music louder. Stop before it hurts.

5 Balanced Male 4-Pin Jack. Plug your Raal/

Requisite headphones in here. It’s designed only

for these headphones. Don’t try it with other

headphones. Don’t make adapters. Seriously, this

is just for Raals, and that is all.

1 Input Switch. If the name wasn’t clue enough,

this selects the input. All the way up for the

internal card (DAC), middle for balanced input,

bottom for SE input. Hint: if you don’t have a card

installed, you won’t hear anything when the card

is selected.

2 Baffle Compensation Switch. Up is on, down

is off. Turn this on when using open-baffle

headphones like the SR1a. Turn it off if using

circumaural headphones.

CONTROLS

5 Balanced Passive Preamp Output. Connect to

powered monitors or a speaker amp with XLR

cables. Remember, this is passive, it doesn’t have

gain or convert types of inputs.

6 On-Off Switch. Up is on. Down is off. Pretty

simple, right?

7 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 the DAC module

installed, the USB input will be here. If you don’t

have a module installed, it will be covered.

2 Balanced Input. Connect a balanced source

here with XLR cables.

3 SE Input. Connect a standard source here with

RCA cables.

4 SE Passive Preamp Output. Connect to powered

monitors or a speaker amp with RCA cables.

Remember, this is passive, it doesn’t have gain or

convert types of inputs.

CONNECTIONS

I hear hum through the headphones, what

do I do to x it?

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

try a ground loop isolator or an EbTech HumX.

There’s no sound for a while after I turn

Jotunheim R on.

That’s perfectly normal. Jotunheim delays the

headphone output for 25-35 seconds after you

rst turn the amp on to allow it to stabilize.

There’s no sound with the input switch

in the top position.

Do you have the optional DAC? If you don’t, you

won’t get any sound.

The Jotunheim R clicks and mutes, then turns

back on again, then clicks and mutes again.

You’re triggering the overcurrent protection.

Check your cables for shorts.Jotunheim R is

intended for use only with Raal/Requisite head-

phones, and should not be used with adapters

for other headphone types, which may short the

output and cause it to go into protection.

FAQ

The Jotunheim clicks and mutes, and stays off

for several minutes, and it’s really hot.

You’re triggering the overtemperature protection.

Reduce the output level or increase ventilation.

Also see the previous comment about not using

adapters for other headphones, and checking your

cables for shorts.

My Windows computer doesn’t see the DAC.

You may need to download and install Windows

drivers. Go to schiit.com/drivers to get them.

I installed the USB drivers, but Windows still

doesn’t see the DAC.

You may be running into USB port power

management problems or bad cables.G o to

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

usb-problems for troubleshooting.

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.
