Einstein The Final cut User manual

- 1 -
Dear EINSTEIN customer,
With your purchase of the EINSTEIN mono amplifiers The Final Cut, you own an audio component of the
highest mechanical and electrical qualities. In order to fully appreciate the great benefits of this unit, we
kindly ask you to carefully read these instructions and manual.
The Final Cut is a two chassis mono-block stereo amplifier of the highest quality, which emphasizes rele-
vant features over unnecessary gimmicks. Some of these features are:
-A realistic playback quality
-Exemplary reliability
-Simple and intuitive usability
-High value
The EINSTEIN The Final Cut amplifier is not a component, which sounds nice, soft or bright. Our goal is to
integrate a component into your existing system, which minimizes its impact on the musical signal. The
mono-blocks transfer the signal directly to the loudspeakers. No world-class loudspeaker could ever correct
for the amplifier’s deficiencies; quite the contrary, good loudspeakers will always tell you the quality of
your amplifier. Incorporating The Final Cut as a component of the highest qualities into your system was
therefore the right choice.
We wish you many hours of happy listening with your EINSTEIN The Final Cut amplifier.
Regards from Bochum,
Volker Bohlmeier

1. Safety information and precautions:
Do not manipulate the component in any way (loss of warranty, danger of electric shock)
For electrical safety reasons never operate the amplifiers without their top cover
The amplifiers must be protected from moisture
Never disconnect the protective conductor
Exchange the safety fuse only with one of the same value
Please contact your dealer / distributor or EINSTEIN directly prior to changing the tubes

3. Technical information
The Final Cut is an OTL amplifier based on innovative and new design concepts. Up until now, the bene-
fits of an OTL based amplifier have never been fully realized in the world of high performance audio. The
technical specification and remarkable sound qualities are a definite testament to that accomplishment.
The Final Cut represents a true milestone in the development of tube amplifiers for audio applications.
4. Placement
When selecting a placement for your amplifiers, please consider proper ventilation of the units as well as a
solid platform for the units to be placed on. The Final Cut should never be placed on top of other compo-
nents nor should other components be placed on top of it. Due to the massive transformers you should
not place a turntable or phono amplifier next The Final Cut amplifier. Separately available equipment
racks can positively affect the sound quality of your new amplifier.
5. Power
The Power supply socket is located on the left side at the back of the unit. This socket also includes the
fuse and one spare. Please make sure that the unit is powered off and not connected to the power outlet
prior to exchanging the fuse. 230V are at the safety clip, EXTREME SHOCK HAZARD!

6. Connecting your amplifier
Please make sure that all connections to your pre-amplifier and loudspeakers have been made prior to
turning the amplifiers on. Should you notice any hum, it may be necessary to connect a ground cable be-
tween the amplifier and pre-amplifier.
Interconnects and cables
You may use any high quality interconnects fitted with balanced XLR style connectors. Please make sure
that the connectors are not oxidized and make a solid and tight connection to the amplifiers. We recom-
mend the use of our own XLR cables, as they are optimized to work best with our EINSTEIN components.
Since The Final Cut amplifier is a fully balanced design, it is critical that you only supply a fully balanced
signal at the input. You may only use a fully balanced pre-amplifier and of course our very own The Tube
pre-amplifier receives the highest recommendation
Loudspeaker cables
Only use high quality loudspeaker cables with properly terminated ends. Make sure that the terminations
are free from oxidation and that the cable’s cross section is wide enough. Using loudspeaker cables that
are too thin minimizes the power transfer from our amplifier and results in a lower damping factor critical
to properly control your loudspeakers.
7. Power switch
To turn power to The Final Cut on or off, please use the left switch on the front panel of the chassis.
Three blue LED’s and lighting of the tubes indicate the status of the amplifier. The Final Cut is ready to
play after approximately 5 minutes when both outside LED’s are switched off. If there is a problem with
the amplifier, either both or one or the other LED will remain lit, at which point you should turn the ampli-
fier off and contact your dealer / distributor or EINSTEIN directly. The unit will achieve its optimal sound
and operating temperature after approximately half an hour. It is recommended that you don’t tax the
amplifiers unnecessarily during this warm up phase as it may result in lower tube life.
8. Control from front face plate
The two front panel mounted switches control the following functions of the amplifier: left switch — on /
off; right switch — standby

9. Connections at the rear of the unit
The rear end of the amplifier contains the speaker connectors (red — right channel; white — left channel)
and balanced inputs.
10. Safety fuse
A blown fuse indicates a fault in your amplifier or mains power. Should your unit not power on after you
have replaced the blown fuse please contact your dealer / distributor or EINSTEIN immediately. The fuse
is of following value: 6.3A slow-blow for 230-240V version and 10A slow-blow for 115- 125V version..
Prior to replacing the fuse, you must disconnect the amplifier from the power line due to shock hazard.
Please make sure that the power cord is disconnected from the power outlet(s). The fuses are located
right next to the power input at the bottom of the unit.
11. Tubes
The Final Cut uses 6C33 type tubes, which have a lifecycle of approximately 2000 hours. In order to
maintain the amplifiers fidelity only the same kind tubes should be used as replacement, as these have
been fully checked and tested by our lab.
12. Service
If you encounter any problems with your pre-amplifier please contact your local dealer / distributor or
EINSTEIN directly.
13. Maintenance & care of your amplifier
Cleaning of all chrome and stainless steel surfaces should only be done with a damp cloth and a small
amount of Windex or similar window cleaner.
14. Tips to improve and tweak the sound quality
You can improve sound quality of the unit by paying attention to these points
Make sure you have proper phase
Use only high quality preferably low impedance interconnects
Connecting the amplifiers to a power conditioner
Use a high quality power cord
Use a high quality rack and support
Make sure you have proper ground in your system
