Dear customer!
With the EINSTEIN The Tune MKII stereo integrated amplifier, you have acquired that
rarest of Hifi components –one that conforms to the most stringent standards of
electrical design and mechanical integrity. To get the most from it, please take a
few leisurely moments and peruse the following instructions.
The Tune MKII is a component that deliberately eschews frilly features to focus in-
stead on the core essentials:
Realistic reproduction with the utmost fidelity
Rock-solid reliability for years of worry-free service
Intuitive user interface everyone in the household can use
Extended market value to protect your investment
The EINSTEIN The Tune MKII does not sound beautiful, soft or energetic. Our goal is to
design components that integrate into existing systems with the absolute minimum
of signal degradation or “artistic license“. As the central nexus of an audio system,
an integrated amplifier’s influence is vital. Even the world’s best source or speakers
cannot correct for losses or errors incurred by this key component. Hence your deci-
sion to incorporate the EINSTEIN The Tune MKII into your system was a truly informed
one. Congratulations.
We extend our regards from Bochum and wish you much musical satisfaction from
your new EINSTEIN The Tune MKII.
Volker Bohlmeier
We are interested in your experience with our amplifier. Please do not hesitate to contact us about anything –may
it be positive or negative. You can help us to improve. (If you take a picture of your hifi equipment and want to
share it with us we would be happy –if you even agree that we may publish your statements and picture on our
web site, please, let us know –this will only happen without your name and location!)
Declaration of Conformity - EINSTEIN Audio Components herewith declares to comply with the requirements set out
in the Council Directive on the Approximation of the Laws of the Member states relating to Electromagnetic Com-
patibility EMC (89/336/EEC) and the Low Voltage Directive LVD (73/23/EEC).

01. Safety concerns - what not to do
Don’t pry inside the machine. It uses high voltages. You’ll void the warranty and risk
electric shock.
Protect the machine against moisture and condensation.
Don’t defeat the ground.
Only replace fuses with original type (1.6A slow-blow for 230-240V version; 3.15A slow-
blow for 100- 125V version)

03. Design overview
The EINSTEIN integrated transistor amplifier The Tune MKII is a double mono design. It contains all
our experience in analog design and digital technique. It is a unique Einstein product that is ex-
emplary for the sound and circuit philosophy that made Einstein a company with international
reputation and worldwide approval.
The amplifier offers all technical attributes of the ‘big’ Einstein amplifiers:
extremely short signal paths
sophisticated power supply with high current headroom
outstanding signal to noise ratio
absolute thermal balance within the casing (basic for high life expectancy and optimal
function of electric parts)
high bandwidth for a detailed musical reproduction without phase problems
no relays in the loudspeaker signal path and therefore no limits in dynamics
volume control realized with resistor network
integrated phono preamplifier suitable for MM as well as high output MC cartridges
optional digital input (USB, DSD, Optical, SPDIF) for highest requirements
04. Setup
Proper HiFi racks with adequate spacing are most suitable and can even improve audible system
performance.
05. AC mains connection
The IEC power inlet and mains fuse holder are located on the back panel. Disconnect the ampli-
fier from the AC plug if you have to replace the fuse. 230/115 volts on the fuse contacts can
cause serious electric shock.
When The Tune leaves our company it is adjusted to the voltage of the importing country. The
voltage is adjustable and can be set to the necessary voltage of your country by your authorized
dealer, the distributor or by EINSTEIN.
Since our customers usually have a preferred power chord we supply a standard one. For more
‘EINSTEIN’ we recommend the custom made EINSTEIN power chord.
06. Component connections.
Before initial power-up, install the interconnects to the sources and the cables to your loudspeak-
ers.

- 4 -
Interconnects Use any high-quality RCA-terminated cable. Insure good non-oxidized contacts.
Naturally, we recommend our own NF cable EINSTEIN The Balance which has been designed for
optimum synergy. But that’s just our opinion. Still, allow us one piece of advice: Use The Tune MKII
to enjoy music, not to test cables.
Loudspeaker cables Insist on cables with superior non-oxidized contacts and sufficient conductor
mass to supply adequate current to the speakers. This insures proper damping factor for manda-
tory transducer control. (Cables of insufficient conductor mass can strangulate an amplifier’s cur-
rent delivery.) The EINSTEIN The Thrill loudspeaker cable is a perfect partner for The Tune MKII.
07. Power mains
To turn the machine on or off, press the rocker mains switch on the back panel right beside the
power inlet. The touch screen panel on the front will confirm power. Thermal stabilization and final
readiness are reached after about 2-3 minutes. Should you have any problem please switch off
the amplifier for 5 minutes. Then switch on the amplifier again. If the problem still exists, contact
your dealer or the factory to avoid internal damage. Optimal operation conditions and stabilized
sonics for The Tune MKII are reached within a half hour of turn-on.
08. Controls on the front
All functions of The Tune MKII can be operated by pressing the buttons in the middle of the front
panel. With the two upper buttons the volume can be adjusted by touching + for louder or –for
lower. Volume is indicated by a row of blue LEDs from minimum (0) to maximum (63).
While pressing the lower two buttons you can select the input of the amplifier.
Inputs
The Tune MKII offers four analog inputs: three high input (CD, Tuner, Line with an input sensivity of
550mV for rated power output / 50kOhm) and one phono input (input sensivity 2,5mV/MM,
1,2mV/MC).
The Tune MKII has an integrated phono preamplifier. It is suitable for MM as well as high output MC
cartridges. Input impedance for MC cartridges is 200 Ohm. For the use of MM cartridges two jum-
pers have to be removed by your dealer or distributor. The input impedance then is 47 kOhm.
The Tune MKII also offers a LINE OUT output which serves either as Preamp Out (the output level
changes according to the volume / 1.8V for rated power output) or as Tape Out (the output level
is independent from the chosen volume). Originally The Tune MKII is delivered with Preamp Out. If
you prefer to use the Tape Out please contact your dealer or distributor.
09. Remote control
The Tune MKII comes with a custom made design remote control called The Control. It is a real
EINSTEIN product with the basic functions for input selection and volume control.
The two upper buttons are for input selection. The volume can be controlled by pressing the two
buttons (–for lower + for higher volume) in the middle. The lowest button is for mute (pressing
once the volume is zero - pressing twice the volume is back to the original level).
To change batteries please remove the black acrylic cover (the one without the EINSTEIN printing)
on the opposite of the function panel by removing the four screws with the provided tool. When
you open the case just change the two AAA batteries. Please make sure you are using high qual-
ity batteries.

10. Fuses
A blown fuse could indicate internal problems. Should the integrated amplifier refuse to operate
after a blown fuse has been replaced, contact your dealer/distributor or EINSTEIN. A proper re-
placement fuse must be marked 1.6A slow-blow for 230/240V version and 3.15A slow-blow for
100V or 115/125V version. Before replacing a fuse, insure that the amplifier is disconnected from
your wall outlet to avoid risk of electric shock.
11. Cleaning
Use a soft cotton cloth and a gentle glass cleaner to polish the acrylic front or to clean the
stainless steel part of the front panel.
12. Service
Should you encounter any problems, please, contact your dealer or EINSTEIN.
13. Performance Tips
You may enjoy improved performance if you pay attention to the following: Correct AC power
phase; high-quality low-impedance interconnects; proper AC mains filtration or conditioning; suit-
able performance power cord; resonance control by way of a well-engineered equipment sup-
port; proper system grounding via a single earth ground; high-quality loudspeaker cables.
14. Warranty
EINSTEIN The Tune MKII carries a 3-year parts & labor non-transferable warranty. For detailed war-
ranty conditions please contact your dealer or the distributor of your country. If you have any fur-
ther questions please feel free to contact [e-mail].
